A few years ago I acquired several Leitz items including a 13.5cm Hektor f/4.5 (screw mount) lens from 1958. Although I have generally been very pleased with the performance of the Leitz lenses I own, the Hektor produced images with a very disappointing lack of sharpness unless closed well down (beyond f/11).

 

The Hektor is not the Leitz lens with the finest reputation. Not knowing much about Leica in general at the time: I just assumed my sample was typical, and ceased using it for the most part.

 

Fast forward to 2022 and my IIIf had become one of the cameras I most often used. So I decided to revisit the Hektor. Once again, although I obtained one or two decent photos with it stopped almost fully down, sharpness was mostly, very poor. So poor, in fact, that I concluded my sample must have been compromised in the past, in some way, by persons unknown. I just couldn't see Leitz sending such a poor optic out the door. Wide open, it was diabolically bad. Indeed, a few hours of online research turned up plenty of images made with other 13.5cm Hektors which were a great deal better than those produced by my own, at any aperture.

 

Fortunately, the 13.5cm Hektor f/4.5 is one of the most affordable of all Leitz lenses and copies are readily available. In late 2022 I purchased another example from a trusted seller (who was kind enough to take some digital test images with the lens for me, prior to ordering it). Having been once bitten, I decided that some basic test images with the new example (also, a 1958 build), were worthwhile, to obtain some first hand data about its behaviour at all its apertures from f/4.5 to f/32.

 

Thus, this series of ostensibly identical images of Hobart's (in)famous Tasman Bridge, which I made at Lindisfarne on the Eastern shore of the River Derwent in February 2023.

 

I make no claim to the series being a definitive benchmark for the characteristics of the 13.5cm Hektor. The images were made because of my own curiosity, to inform my use of the new lens in future. That said, I have shared them here in case they might be helpful for other film photographers.

 

Friday 3rd February 2023.

Camera: Leica IIIf RD 35mm Rangefinder (1952).

Lens: Leitz 13.5cm Hektor f/4.5 (1958).

Film: Ilford FP4 Plus ISO 125 35mm black & white negative.

Exposure: 1/50 @ f/4.5.

Development: ID-11 1 + 3 20C/21m.

 

Other details:

A Leitz APDOO accessory self timer and Linhof tripod were used to release the shutter without reducing stability. The Hektor couples accurately to my well-adjusted IIIf rangefinder at infinity, and was set to its infinity stop for these photos. Only shutter duration and aperture were altered between images, to maintain a nearly equivalent amount of exposure for each image during the series.

 

The processed film was scanned using a well set up Epson V700 at 3200ppi 16 bit depth and saved as tiff. Each image was very slightly cropped to remove any film rebate acquired during the scan to the standard 35mm format 3:2 ratio, and very slightly reduced in size to 15 x 10 inches at 300ppi resolution using a bicubic sharper resizing algorithm in Photoshop 2020. Minor adjustments were made to brightness and contrast in several cases, (to compensate for any slight variations in exposure resulting from the slowly changing evening light levels and the Leica's not completely linear scale of shutter speeds).

 

The edited tiffs were resized to 2400 x 1600 pixels using bicubic sharper resizing again, sharpened with a 2 pixel high pass filter, and saved as RBG jpegs with minimum possible compression before being added to Flickr.

OK, so I've got a thing for benches, and I happen to think this shot, taken early in the Morning, on Hamstead Heath, is quite cool. Shallow DoF light, perspective, comp, all those things.

 

But I still in Flickr terms it will be a bust.

 

There's a method in my madness though - I have a stunner to put up next, and I've noted before that if Flickr whimsically condescends to let a shot run high in Explore, it zaps the next one. So here's one I like but I expect very few other people will, just to break the pattern...

Some background:

The Saab 35 Draken ('The Kite' or 'The Dragon') was a Swedish fighter-interceptor developed and manufactured by Svenska Aeroplan Aktiebolaget (SAAB) between 1955 and 1974. Development of the Saab 35 Draken started in 1948 as the Swedish air force future replacement for the then also in development Saab 29 Tunnan dayfighter and Saab 32B Lansen night fighter. It featured an innovative but unproven double delta wing, which led to the creation of a sub-scale test aircraft, the Saab 210, which was produced and flown to test this previously unexplored aerodynamic feature. The full-scale production version entered service with frontline squadrons of the Swedish Air Force on 8 March 1960. It received the designation Flygplan 35 (Fpl 35; 'Aeroplane 35') and was produced in several variants and types, most commonly as a fighter type with the prefix J (J 35), standing for Jaktflygplan (Pursuit-aircraft), the Swedish term for fighter aircraft.

 

The Saab 35 Draken was known for, among other things, its many "firsts" within aviation. It was the first Western European-built combat aircraft with true supersonic capability to enter service and the first fully supersonic aircraft to be deployed in Western Europe. Design-wise it was one of, if not the first, combat aircraft designed with double delta wings, being drawn up by early 1950. The unconventional wing design also had the side effect of making it the first known aircraft to perform and be capable of the Cobra maneuver. It was also one of the first Western-European-built aircraft to exceed Mach 2 in level flight, reaching it on 14 January 1960.

 

The Draken functioned as an effective supersonic fighter aircraft of the Cold War period. Even though the type was designed and intended as an interceptor, the Draken was considered to be a very capable dogfighter for the era, and its large wing area allowed the compact Saab 35 to carry a relatively high payload, too. In Swedish service, it underwent several upgrades, the ultimate of these being the J 35 J model which served until 1999. The Draken was also exported to several countries and remained operational in Austria until 2005.

 

In Swedish service, the Saab 35 was replaced by the Saab 37 “Viggen”. Development work on the new type was already initiated at Saab in 1952 and, following the selection of a radical canard delta wing configuration, the resulting aircraft performed its first flight on 8 February 1967 and entered service on 21 June 1971. However, being a radical and new design, the service introduction of the Viggen – esp. of its initial version, the AJ 37 fighter-bomber – was not without teething troubles, and in the late Sixties the Swedish Air Force expected an attack aircraft gap in its line-up. The former A 32 A Lansen attack aircraft were reaching the end of their airframe lifetime and were simply outdated, even though it was still needed as an anti-ship attack platform for the indigenous Rb 04 guided missile, so that Saab suggested an interim solution: the conversion of seventy of the 120 produced J 35 D fighters into dedicated attack aircraft, with the designation A 35 G (Gustav).

 

The Saab A 35 G was heavily modified to make it into a fighter bomber aircraft. Compared to the fighter versions the outer wings where completely redesigned and the aircraft featured 9 hardpoints in total. Airframe and landing gear were strengthened to cope with an increased payload of 10,000 lb (4,540 kg) vs. the fighters’ usual 6,393 lb (2,900 kg). Several airframe components were restored or replaced to extend the life of the aircraft, and the landing gear featured low-pressure tires for a better field performance on improvised/dispersed airfields.

A wide array of ordnance could be carried, such as bombs of up to 1.000 lb (454 kg) caliber, MERs with up to six 100 kg (220 lb) bombs each, pods with unguided 75 mm or 135 mm rockets, single 14.5 cm psrak m49/56 high-explosive anti-tank rockets and, as a new weapon, the indigenous guided Rb 05 air-to-ground missile. This had been developed for the AJ 37 "Viggen in 1967 and was roughly comparable with the American AGM-12 Bullpup, but had some unique features. The Rb 05’s supersonic speed was deemed necessary to reduce the threat of surface-to-air missiles, and it allowed the missile to be deployed against slow/large aerial targets, too, making it a dual-purpose weapon. Consequently, the Rb 05’s fuze could be set by the pilot to impact mode for ground targets, or proximity mode for attacking air targets such as bombers.

The missile had a maximum range of 9 km (5.6 ml) and would usually be launched after a high-speed attack run on very low altitude and a climb to 400m for launch. Since the RB 05 was roll-stabilized, the aircraft did not need to be aimed straight at the target when launching and could immediately descend into terrain cover again, and this also made it possible to attack aerial targets from unusual angles and flight paths. Tracking the flares on the missile, the pilot would then visually guide the missile (the missile's engine was smokeless as to not obscure the view) with a small manual joystick towards the target. Guidance commands were transmitted to the missile via a jam-proof radio transmission link.

 

The A 35 G kept the J 35 D’s two 30 mm ADEN cannons, and a limited air defense capability was retained, too: the Gustav could carry up to four IR-guided Rb 24 (AIM-9B Sidewinder) AAMs, in addition to the Rb 05 in air-to-air mode. However, the aircraft lacked any air intercept radar, and had instead a Ferranti LRMTS (laser rangefinder and marked target seeker) and a counterweight installed in the nose, which resembled the S 35 E photo reconnaissance version’s nose, just without the windows for the side-looking cameras. For its attack role, the A 35 G received a new inertial navigation system, new altimeters and a ballistic computer from Saab called BT-9Rm, which worked with both bombs and rockets and even allowed for toss bombing. The Gustav Draken was furthermore fitted with electronic countermeasure (ECM) systems, a RHAWS and chaff and flare dispensers in their tail cones to improve its survivability over the battlefield.

 

The Gustav conversion program was accepted by the Swedish government in 1968. Work started in early 1969, the first revamped aircraft reached the operational units in late 1971. However, since production of the AJ 37 was starting at the same time, only 61 aircraft were eventually re-built from existing J 35 D airframes (one prototype and sixty production aircraft). Västgöta Wing (F 6) at Karlsborg was the first squadron to receive the A 35 G, replacing its A 32 A fighter bombers, the other unit to operate the type was Skaraborg Wing (F 7) at Såtenäs.

 

Among Sweden’s Draken fleet the Gustav was easy to recognize because it was the only version that carried the new “Fields & Meadows” splinter camouflage as standard livery. Service of the A 35 G lasted only until the early Eighties, though: as more and more AJ 37 all-weather fighter bombers reached the Swedish frontline units during the Seventies, the interim attack Draken, which was only effective under daylight and more or less good weather conditions, was withdrawn and either used for spares in the running J 35 J modernization program or directly scrapped, because many airframes had, suffering from the special stress of low-level flight operations, reached the end of their lifespan.

 

Another factor for the quick withdrawal was the disappointing performance of the type’s primary weapon, the Rb 05 missile: Its manual joystick steering in the cramped Draken cockpit (to be operated while the pilot was expected to fly at low altitude and evade enemy fire!) presented a number of problems, and the Rb 05’s ultimate accuracy was, even under ideal conditions, on the order of just 10 meters (33 ft), greater than desired. Targets like tanks or even ships were hard to hit with this level of scattering, combined with imminent danger for the pilot, and the air-to-air mode was even less effective. On the more modern Saab 37 the Rb 05 was therefore replaced by the Rb 75, a license-produced version of the American TV-guided AGM-65 Maverick “fire and forget” weapon. TV and laser seeker heads for the Rb 05 to improve the weapon’s accuracy and handling had been planned since the early Seventies, but were never realized.

The kit and its assembly:

Even though the model depicts a what-if aircraft, the Draken’s proposed “Gustav” attack variant based on the J 35 D interceptor was real – even though I could not find much detail information about it. So, I took some inspiration from the contemporary Danish Saab 35XD export version, which probably had similar features to the Gustav? Another inspiring factor was a pair of Rb 05 missiles (from an Airfix Viggen) that I had bought with a spare parts lot some time ago – and an attack Draken would be the perfect carrier for these exotic (and unsuccessful) missiles.

 

For a low-budget build I used one of Mistercraft’s many recent re-boxings of the vintage Revell Draken from 1957(!), and this kit is nothing for those who are faint at heart. It is horrible.

The kit probably depicts a late J 35 A (already with a long tail section), but even for this variant it lacks details like the air scoops for the afterburner or a proper landing gear. The Draken’s characteristic tail wheel is also missing completely. Worst pitfall, however: there is NO interior at all, not even a lumpy seat! The canopy, the early model with struts, is disturbingly clean and crisp, though. The overall fit is mediocre at best, too – there are only a few visible seams, but any of them calls for filling and PSR. It’s a very toyish kit, even though the general outlines are O.K.

And the Mistercraft instructions are really audacious: they show all the parts that are actually NOT there at all. Suddenly a seat appears in the cockpit, a fin fairing from a J 35 D or later, or the tail wheel… And the decal sheets only roughly meet the aircraft you see in the painting instructions - there are three sheets, totally puzzled together, including material for aircraft not mentioned in the instructions, but that’s a common feature of most Mistercraft kits. But: how much can you taunt your disappointed customers?

 

So, this leaves lots of room for improvements, and calls for a lot of scratching and improvisation, too. First measure was to open both the air intakes (which end after 2mm in vertical walls) and the exhaust, which received an afterburner dummy deep inside to create depth. Next, I implanted a complete cockpit, consisting of s scratched dashboard (styrene sheet), the tub from an Italeri Bae Hawk trainer’s rear cockpit (which comes with neat side consoles and fits quite well) plus a shallow vintage ejection seat, probably left over from an early MiG from a KP kit or one of its many later reincarnations. As an alternative, there’s a Quickboost resin aftermarket set with a complete cockpit interior (even including side walls, IIRC intended to be used with the Hasegawa Draken) available but using it on this crappy kit would have been a waste of resources – it’s more expensive than the kit itself, and even with a fine cockpit the exterior would still remain sh!t.

 

Since I could not find any detail about the Gustav Draken’s equipment I gave it a laser rangefinder in a poor-fitting S 35 E (or is it a Danish export F-35?) nose that comes as an optional part with the vintage Revell mold – which is weird, because the recce Draken was built between 1963 and 1968 in 2 series, several years after the kit’s launch? Maybe the Mistercraft kit is based on the 1989 Revell re-boxing? But that kit also features an all-in-one pilot/seat part and a two-piece canopy… Weird!

 

Once the hull was closed many surface details had to be added. The afterburner air scoops were created from plastic profiles, which are aftermarket roof rails in H0 scale. Styrene profile material was also used to create the intakes behind the cockpit, better than nothing. The OOB pitot on the fin was very robust, and since it would be wrong on a J 35 D I cut it off and added a fairing to the fin tip, a shortened/modified ACMI pod, which bears a better pitot alternative at its tip. The pitot on the nose was scratched from heated styrene, since the kit offers no part at all.

 

Under the rear fuselage the whole tail wheel arrangement had to be scratched. The shallow fairing consists of a section from a Matchbox EA-6B drop tank, the wheel and its strut were tinkered together with bits from the scrap box and profile material. Not stellar, but better than OOB (= nothing!).

The landing gear struts were taken from the kit but beefed up with some details. The main wheels had to be replaced, the new ones come from a KP MiG-21, IIRC.

 

The ordnance consists of a pair of Rb 05’s from an Airfix Viggen, a pair of OOB drop tanks and MERs from a Matchbox A-7D, together with fourteen streamlined bombs from the same kit – twelve on the MERs and single bombs on the outer pylons. AFAIK, Sweden never used MERs on their aircraft, but the bombs come pretty close to some small bombs that I have seen as AJ 37 ordnance. Most pylons are OOB, I just added a single ventral station and two outer hardpoints under the wings. The Rb 05s received a prominent place under the air intakes on Sidewinder launch rails.

  

Painting and markings:

Finally a good excuse to apply the famous and complex “Fields & Meadows” paint scheme to a Draken model! However, this “combo” actually existed in real life, but only on a single aircraft: around 1980 a J 35 B (s/n 35520), aircraft “20” of F18, was painted in this fashion, but AFAIK it was only an instructional airframe. You find some pictures of this aircraft online but getting a clear three-side view (esp. from above!) as a reliable painting benchmark is impossible. However, a complete paint scheme of this aircraft is provided with one of Mistercraft’s Revell Draken re-boxings (not the one I bought, though), even though it is mismarked as a J 35 F of F10 in the instructions. One of the common Mistercraft errors, err, “surprises” (*sigh*).

 

Finding suitable model paints for the elaborate scheme is not easy, either, and after having applied it several times I stuck to my favorites: Humbrol 150 (Forest Green, FS 34127), 75 (Bronze Green), 118 (US Light Tan, FS 30219, a bit light but RAF Dark Earth is too somber) and Revell 06 (Tar Black, RAL 9021) on the upper surfaces and Humbrol 247 (RLM76) underneath.

A large ventral section was, typical for the J 35, left in bare metal, since leaking fuel and oil would frequently eat away any paint there. The section was painted with Revell 91 (Iron) and later treated with Matt Aluminum Metallizer (Humbrol). As per usual, the model received an overall light black ink washing and some post-shading in order to emphasize the panels, correct the splinter camouflage and dramatize the surface. Some extra weathering was done around the gun ports and the jet nozzle with graphite.

 

Internal details like the cockpit and the landing gear were painted with the help of Swedish Saab 35 reference pictures. The cockpit tub was painted in a dark, bluish green (Humbrol 76) with grey-green (Revell 67) side walls.

The landing gear and its respective wells were painted in a bluish grey (Revell 57), parts of the struts were painted in a bright turquoise (a mix of Humbrol 89 and 80; looks quite weird, but I like such details!). The wheel hubs became medium grey (Revell 47). The Rb 05 missiles were painted in white as live weapons, so that they stand out well from the airframe. The drop tanks received the same blue-grey as the underside (Humbrol 247). MERs and launch rails were painted in a neutral grey (RAL 7001) and the bombs became olive drab (RAL 6014, Gelboliv) with yellow rings and golden fuzes.

 

Decals/markings were puzzled together from a Moose Republic Saab 32 sheet (unit code number and emblem) and the spares box, including the red tactical tail code from an Italeri 1:72 Gripen and roundels from a Hasegawa Draken. Stencils were taken from the kit’s OOB sheet and also from the Hasegawa Draken sheet. Finally, the model was sealed with matt acrylic varnish (Italeri).

  

What a horror trip! The paint scheme itself was/is challenging enough, but modding the crappy vintage Revell kit into something more presentable was already a fight in itself. However, I like the outcome. “Fields & Meadows” suits the Draken with its huge and flat upper surface well, and while the Gustav conversion did not take much effort the “mud mover” ordnance under this Mach 2 fighter really looks strange and makes you wonder what this is. A nice what-if model, despite its blurriness!

This is a USGS benchmark. There are many thousands like it. I'm drawn to them because most have their typography damaged in some unique way.

Some background:

A monitor is a class of relatively small warship that is lightly armoured, often provided with disproportionately large guns, and originally designed for coastal warfare. The term "monitor" grew to include breastwork monitors, the largest class of riverine warcraft known as river monitors and was sometimes used as a generic term for any turreted ship. In the early 20th century, the term "monitor" included shallow-draft armoured shore bombardment vessels, particularly those of the Royal Navy: the Lord Clive-class monitors carried guns that fired the heaviest shells ever used at sea and saw action against German targets during World War I.

Two small Royal Navy monitors from the First World War, Erebus and Terror survived to fight in the Second World War. When the requirement for shore support and strong shallow-water coastal defence returned, new monitors and variants such as coastal defence ships were built. Allied monitors saw service in the Mediterranean in support of the British Eighth Army's desert and Italian campaigns, and they were part of the offshore bombardment for the Invasion of Normandy in 1944.

 

During the First World War, the Royal Navy developed several classes of ships which were designed to give close support to troops ashore through the use of naval bombardment. The size of the various monitor classes of the Royal Navy and their armaments varied greatly. The Marshal Ney class was the United Kingdom's first attempt at a monitor carrying 15 in (381 mm) guns, two of these ships were eventually built and showed a disappointing performance. The Admiralty immediately began the design of a replacement class, which incorporated lessons learned from all of the previous monitor classes commissioned during the war. Some of the main modifications were an increase in the power supply to guarantee a speed of 12 knots (22 km/h; 14 mph) and a change to the angles and lines of the hull to improve steering. Another significant change was to raise the top of the anti-torpedo bulge above the waterline and reduce its width; both changes would improve the stability and maneuverability of the ship at sea. The new design would later be named the Erebus-class, the first ship being launched in June 1916. Two ships were built and took part in WWI, but the Admiralty was not fully convinced with these ships, which also had shown major operational flaws, and requested in early 1918 three ship from another monitor class with higher firepower and better performance at sea, which led to the Trebuchet-class – even though it came too late to take part in any hostilities.

 

The class’ ships were to be the name-giving HMS Trebuchet, HMS Mangonel and HMS Ludgar. The latter would be the first and eventually become the class' only ship, because Trebuchet and Mangonel were quickly cancelled. HMS Ludgar was named after the famous, probably largest trebuchet ever made, also known as “Warwolf”, which had been created in Scotland by order of King Edward I of England, during the siege of Stirling Castle, as part of the Scottish Wars of Independence. Still seeing a need for this specialized ship for local conflicts in the British Empire around the world, Ludgar was proceeded with and laid down at Harland and Wolff's shipyard in Govan on 12 October 1918.

 

Due to the lack of wartime pressure, though, Ludgar took three years to complete and was launched on 19 June 1920. The new design was a thorough re-modelling of the earlier Royal Navy Monitors, even though most basic features and the general layout were retained - with all its benefits and flaws. Overall the ship was slightly larger than its direct predecessors, the Erebus-class monitors. Ludgar had a crew of 224, 9,090 long tons (9,185 t) loaded displacement, was 436 ft (133.1 m) long, 97 ft (29.6 m) wide with a draught of just 11 ft 8 in (3.6 m, less than a destroyer) for operations close to the coastline. Power was provided by four Babcock & Wilcox water-tube boilers, which would generate a combined 6,000 ihp (4,500 kW) that were produced by triple-expansion steam engines with two shafts. The monitor had an operational range of 2,480 nmi (4,590 km; 2,850 mi) at a speed of 12 knots.

 

HMS Ludgar’s deck armor would range from 1 in (25 mm) on the forecastle, through 2 in (51 mm) on the upper deck and 4 in (102 mm) over the magazine and belt. Unlike former British monitors, the Trebuchet Class featured two main turrets, which were each armed with two 15 in guns, what considerably improved the ship’s rate of fire. With the main 15 in guns being originally intended for use on a battleship, the armor for the turrets was substantially thicker than elsewhere in the design; with 13 in (330 mm) on the front, 11 in (279 mm) on the other sides and 5 in (127 mm) on the roof. The main guns' barbettes would be protected by 8 in (203 mm) of armor. Learning from the earlier experience with Ney, the turrets were adjusted to increase elevation to 30 degrees, which would add greater firing range. The 15 in guns had a muzzle velocity of 2,450 feet per second (750 m/s) – 2,640 feet per second (800 m/s), with supercharge. Maximum firing range was 33,550 yards (30,680 m) with a Mk XVIIB or Mk XXII streamlined shell @30° – 37,870 yards (34,630 m) @ 30°, with supercharges.

 

Just like on former British monitor ship designs, the turrets had to be raised high above the deck to allow the small draught, what raised the ship’s center of gravity and required a relatively wide hull to ensure stability.

The tall conning tower was protected by 6 in (152 mm) of armor on the sides and 2.5 in (64 mm) on the roof. The former monitors retrofitted anti-torpedo bulges were integrated into the Trebuchet-class’ hull, extending the deck’s width and giving the ship a more efficient shape, even though the short and wide hull still did not support a good performance at sea. The outer air-filled compartments under the waterline were 13 ft (4 m) wide with a 9 ft (2.7 m) wide outer section and an inner compartment 4 ft (1.2 m) wide containing an array of protective, air-filled steel tubes which would take the blast from an eventual broadside torpedo hit.

 

Ludgar conducted sea trials on 1 September 1921, during which the ship was faster than her predecessors at 16.5 knots (30 km/h; 19 mph) compared to 13 knots (24.3 km/h; 15.1 mph) for the Erebus-class monitors. However, like her ancestors, the wide and shallow hull of Ludgar made the ride rather unstable, and under practical conditions the ship’s top speed rarely exceeded 14 knots, making Ludgar only marginally faster than older monitor ships. The inherent flaws of the ship class’ design could not easily be overcome. However, Ludgar was officially commissioned on 2 September.

 

Upon entering service Ludgar was immediately deployed to the eastern Mediterranean as part of the 1st Battle Squadron of the Atlantic Fleet to mediate conflicts between Greece and the crumbling Ottoman Empire. While in the Ottoman capital Constantinople, Ludgar and the other British warships took on White émigrés fleeing the Communist Red Army.

The 1922 Washington Naval Treaty cut the battleship strength of the Royal Navy from forty ships to fifteen. The remaining active battleships were divided between the Atlantic and Mediterranean Fleets and conducted joint operations annually. Ludgar remained with the Mediterranean through 1926. On 4 October 1927, the ship was placed in reserve to effect a major refit, in which new rangefinders and searchlights were installed and the ship's original secondary armament, eight 4 inch naval guns against enemy destroyers and torpedo boats, was replaced be anti-aircraft guns of the same caliber.

On 15 May 1929 the refit was finished, and the ship was assigned to the 1st Battle Squadron of the Mediterranean Fleet. The squadron also consisted of Royal Sovereign, her sisters Resolution and Revenge, and Queen Elizabeth, and based in Malta. The only changes made during the Thirties were augmentations to Ludgar’s anti-aircraft batteries.

 

Fleet exercises in 1934 were carried out in the Bay of Biscay, followed by a fleet regatta in Navarino Bay off Greece. In 1935, the ship returned to Britain for the Jubilee Fleet Review for King George V. In August 1935, Ludgar was transferred to the 2nd Battle Squadron of the Atlantic Fleet, where she served as a training vessel until 2 June 1937, when she was again placed in reserve for a major overhaul. This lasted until 18 February 1938, after which she returned to the 2nd Battle Squadron.

 

In early 1939, the Admiralty considered plans to send Ludgar to Asia to counter Japanese expansionism. They reasoned that the then established "Singapore strategy", which called for a fleet to be formed in Britain to be dispatched to confront a Japanese attack was inherently risky due to the long delay. They argued that a dedicated battle fleet would allow for faster reaction. The plan was abandoned, however. In the last weeks of August 1939, the Royal Navy began to concentrate in wartime bases as tensions with Germany rose.

At the outset of war in September 1939, Ludgar was assigned to the 2nd Battle Squadron of the Home Fleet but remained at Plymouth for a short refit. In May 1940, painted in an overall light grey livery, she moved to the Mediterranean Fleet. There she was based in Alexandria, together with the battleships Warspite, Malaya, and Valiant, under the command of Admiral Andrew Cunningham.

 

In mid-August 1940, while steaming in the Red Sea, Royal Sovereign was attacked by the Italian submarine Galileo Ferraris and lightly damaged. Later that month, she returned to Alexandria for repairs and she received false white wakes at front and stern to simulate speed and confuse enemies. At the same time the conning tower was painted in a very light grey to make it less conspicuous when the ship was lurking behind the horizon. These were combined with periodic maintenance and the stay at dock lasted until November 1940.

Ludgar then moved to North Africa where she supported Operation Compass, the British assault against the Italian Tenth Army in Libya. The monitor shelled Italian positions at Maktila in Egypt on the night of 8 December, as part of the Battle of Sidi Barrani, before coming under the command of Captain Hector Waller's Inshore Squadron off Libya on 13 December. During the successful advance by the Western Desert Force Terror bombarded Italian land forces and fortifications, amongst others the fortified port of Bardia in eastern Libya on 16 December. After the Bardia bombardment concern was raised about the condition of the 15 in gun barrels which had been fitted, having been previously used, in 1939. The barrels were inspected by Vice Admiral Sir Andrew Cunningham and the order was given for Ludgar to reduce the amount of cordite used when firing the main guns, in an attempt to extend the weapons' useful life. In a further attempt to conserve the monitor's main guns, her duties were changed to concentrate on providing anti-aircraft cover for the rest of the squadron and to ferry supplies from Alexandria. The ship also served as a water carrier for the advancing British and Commonwealth army.

 

Along with the flotilla leader Stuart, the gunboat Gnat and the destroyers Vampire and Voyager, Ludgar supported the assault on Tobruk on 21 January 1941 by the 6th Australian Division with the port being secured on 22nd. By this point the monitor's main gun barrels had each fired over 600 rounds of ammunition and the rifling had been worn away. While the main guns could still be fired, the shots would rarely land accurately and frequently exploded in mid-air. Ludgar was now relegated solely to the role of a mobile anti-aircraft platform and her light anti-aircraft armament was supplemented by two triple two-pounder anti-aircraft guns, mounted in armored turrets in front of the bridge and on a small platform at stern. To make room for the latter the original locations of the ship's lifeboats was moved from stern to the main deck behind the funnel, and a large crane was added there to put them afloat. The crane was also able to deploy a light reconnaissance float plane - and for a short period in early 1941 Ludgar carried a Fairey Seafox biplane, despite having neither catapult nor hangar. However, since the aircraft was exposed to the elements all the time and quite vulnerable, it soon disappeared.

At this phase the ship started sporting an unofficial additional camouflage which consisted of irregular small patches in sand, brown and khaki over her basic grey livery, apparently applied in situ with whatever suitable paint the crew could get their hands on, probably both British Army and even captured Italian paints. The objective was to better hide the ship against the African coastline when supporting land troops.

 

In March 1941, Ludgar was involved in Operation Lustre, the Allied reinforcement of Greece. The turn of fortune against the Allies in April required the evacuation of most of these forces, Operation Demon. On 21 April Ludgar was in Nafplio and accounted for the evacuation of 301 people, including 160 nurses. Following this, the ship became involved with the Tobruk Ferry Service, and made 11 runs to the besieged city of Tobruk before engine problems forced her withdrawal in July. Ludgar sailed again to Alexandria for repairs, which lasted from September 1941 to March 1942.

 

Ludgar – now re-fitted with new main gun barrels and two more Oerlikon AA machine cannon to the original complement of eight – was then assigned to Force H in the Mediterranean. Operation Torch saw British and American forces landed in Morocco and Algeria under the British First Army. Force H was reinforced to cover these landings and Ludgar provided heavy artillery support for the land-based ground troops. The end of the campaign in North Africa saw an interdiction effort on a vast scale, the aim was to cut Tunisia completely off from Axis support. It succeeded and 250,000 men surrendered to the 18th Army Group; a number equal to those who surrendered at Stalingrad. Force H again provided heavy cover for this operation.

 

Two further sets of landings were covered by Force H against interference from the Italian fleet. Operation Husky in July 1943 saw the invasion and conquest of Sicily, and Operation Avalanche saw an attack on the Italian mainland at Salerno. Following the Allied landings on Italy itself, the Italian government surrendered. The Italian fleet mostly escaped German capture and much of it formed the Italian Co-Belligerent Navy. With the surrender of the Italian fleet, the need for heavy units in the Mediterranean disappeared. The battleships and aircraft carriers of Force H dispersed to the Home and Eastern Fleets and the command was disbanded. Naval operations in the Mediterranean from now on would be conducted by lighter units, and Ludgar was commanded back to Great Britain, where she was put into reserve at Devonport, enhancing the station’s anti-aircraft defense.

At Devonport Ludgar was repainted in a dark grey-green Admiralty scheme and on 2 June 1944 she left Devonport again, joining Bombardment Force D of the Eastern Task Force of the Normandy invasion fleet off Plymouth two days later. At 0500 on 6 June 1944 Ludgar was the first ship to open fire, bombarding the German battery at Villerville from a position 26,000 yards offshore, to support landings by the British 3rd Division on Sword Beach. She continued bombardment duties on 7 June, but after firing over 300 shells she had to rearm and crossed the Channel to Portsmouth. She returned to Normandy on 9 June to support American forces at Utah Beach and then, on 11 June, she took up position off Gold Beach to support the British 69th Infantry Brigade near Cristot.

On 12 June she returned to Portsmouth to rearm, but her guns were worn out again, so she was ordered to sail to Rosyth via the Straits of Dover. She evaded German coastal batteries, partly due to effective radar jamming, but hit a mine 28 miles off Harwich early on 13 June. The explosion ripped her bow apart, leaving a gaping leak, and she sank within just a couple of minutes. Only 57 men of Ludgar’s crew survived.

The kit and its assembly:

This was another submission for the "Gunships" group build at whatifmodellers.com in late 2021 - and what would such a competition be without a literal "gunship" in the form of a monitor ship? I had wanted to scratch such a vehicle for a while, and the GB was a good motivation to tackle this messy project.

 

The idea was to build a post-WWI monitor for the Royal Navy. From WWI, several such ships had survived and they were kept in reserve and service into WWII, some even survived this war after extensive use. However, the layout of a typical monitor ship, with low draft, a relatively wide hull and heavy armament for land bombardments, is rather special and finding a suitable basis for this project was not easy - and I also did not want to spend a fortune just in donor parts.

Then I recently came across Hobby Boss 1:700 kit of the USS Arizona (in its 1941 guise, w/o the hull barbettes), and after some comparison with real British monitors I found my starting point - and it was dirty cheap. Righteously, though, because the model is rather primitive, comparable with the simple Matchbox 1:700 waterline ships. There are also some dubious if not cringeworthy solutions. For instance, in order to provide the superstructures with open windows, the seams between the single levels run right through the windows! WTF? These seams can hardly be hidden, it's really an awkward solution. Another freak detail: the portholes on the lower hull protrude like pockmarks, in real life they'd the 1 1/2 ft (50 cm) deep?! Some details like the cranes on the upper deck are also very "robust", it is, in the end, IMHO not a good model. But it was just the starting for me for "something else"...

 

Modifications started with shortening the hull. Effectively, I cut out more then 3 1/2 in from the body, which is an integral part with side walls and main deck, basically any straight hull section disappeared, leaving only the bow and stern section. My hope was that these could be simple glued together for a new, wide hull - but this did not work without problems, because the rear section turned out to be a bit wider than the front. What to do...? I eventually solved this problem through wedge-shaped cuts inside of the integral railings. With some force, lots of glue and a stiffening structure inside the new hull could be completed.

 

Next the original turret bases had to disappear. as well as two of the four anchors and their respective chains on the foredeck. I retained as much of the original superstructure as possible, as it looked quite plausible even for a shorter ship, but since the complete hull basis for it had been gone, some adaptations had to be made. The main level was shortened a little and I had to scratch the substruction from styrene sheet, so that it would match with the stepped new hull.

At the same time I had to defined where the main turret(s) would be placed - and I settled for two, because the deck space was sufficient and the ship's size would make them appear plausible. A huge problem were the turret mounts, though - since a monitor has only little draught, the hull is not very deep. Major gun turrets are quite tall things, on battleships only the turret itself with the guns can be normally seen. But on a monitor they stand really tall above the waterline, and their foundation needs a cover. I eventually found a very nice solution in the form of 1:72 jet engine exhausts from Intech F-16s - I has a pair of these featureless parts in the spares box, and with some trimming and the transplantation of the original turtret mounts the result looks really good.

 

In the meantime the hull-mounted gun barbettes of USS Arizona had to disappear, together with the pockmarks on the hull. A messy affair with several PSR rounds. Furthermore, I added a bottom to the waterline hull, cut from 0.5 mm styrene sheet, and added plaster and lead beads as ballast.

 

Most of the superstructure, up to the conning tower, were mostly taken OOB. I just gave the ship a more delicate crane and re-arranged the lifeboats, and added two small superstructures to the rear deck as AA-stations, behind the rear tower - the space had been empty, because USS Arizona carried aircraft catapults there.

 

For the armament I used the OOB main turrets, but only used two of the three barrels (blanking of the opening in the middle). The 4 in guns were taken OOB to their original positions, the lighter 20 mm AA guns were partly placed in the original positions, too, and four of them went to a small platform at stern. For even more firepower I added two small turrets with three two-pounder AA guns, one on the rear deck and another right in front of the bridge.

  

Painting and markings:

The ship might look odd in its fragmented multi-colored camouflage - but this scheme was inspired by the real HMS Terror, an monitor that operated in early 1941 on the coast of North Africa and carried a similar makeshift camouflage. This consisted of a multitude of sand and brown tones, applied over an overall light grey base. I mimicked this design, initially giving the ship at first a uniform livery in 507b (Humbrol 64), together with an unpainted but weathered wooden deck (Humbrol 187 plus a washing with sepia ink) and horizontal metal surfaces either in a dark grey (507a, Humbrol 106) or covered with a red-brown coat of Corticene (Humbrol 62). As a personal detail I gave the ship false bow and stern waves on the hull in white. Another personal mod is the light grey (507c, Humbrol 147) conning tower - as mentioned in the background, I found that this light grey would be most useful when the ship itself was hidden behind the horizon from view, and only the conning tower would be directly visible in front of a hazy naval background.

On top of the grey hull I added several other paints, including khaki drab (FS 34087 from Modelmaster), red brown (FS 30118, Humbrol 118), khaki drill (Humbrol 72), mid stone (Humbrol 225) and light stone (Humbrol 121).

 

The model received an overall washing with dark grey and some rust stains with various brown and red shades of simple watercolors. The waterline was created with long and thin black 1.5 mm decal stripes, a very convenient and tidy solution. Finally, all parts were sealed with matt acrylic varnish, and after the final assembly I also added some rigging to the main mast with heated black sprue material.

  

Phew, this was quite a challenge, the result looks good overall, but I am not happy with the finish. Ships are not my strength and you see the Hobby Boss kit's flaws and weaknesses everywhere. Then add massive bodywork, and thing look even more shaggy (*sigh*). Nevertheless, the model looks like a typical monitor ship, and when I take the rather crappy USS Arizona kit as basis/benchmark, the "new" HMS Ludgar is not a bad achievement. It's surely not a crisp model, but the impression is good and this is what counts most to me.
