Some background:

In Autumn 1946, the Saab company began internal studies aimed at developing a replacement aircraft for the Saab B 18/S 18 as Sweden's standard attack aircraft. In 1948, Saab was formally approached by the Swedish Government with a request to investigate the development of a turbojet-powered strike aircraft to replace a series of 1940s vintage attack, reconnaissance, and night-fighter aircraft then in the Flygvapnet’s inventory. On 20 December 1948, a phase one contract for the design and mock-up of the proposed aircraft was issued. The requirements laid out by the Swedish Air Force were demanding: the aircraft had to be able to attack anywhere along Sweden's 2,000 km (1,245 miles) of coastline within one hour of launch from a central location, and it had to be capable of being launched in any weather conditions, at day or night.

 

In response, Saab elected to develop a twin-seat aircraft with a low-mounted swept wing and equipped with advanced electronics. On 3 November 1952, the first prototype, under the handle “Fpl 32” (flygplan = aircraft) conducted its first flight. A small batch of prototypes completed design and evaluation trials with series production of the newly designated Saab 32 Lansen beginning in 1953. The first production A 32A Lansen attack aircraft were delivered to the Swedish Air Force and proceeded through to mid-1958, at which point manufacturing activity switched to the Lansen’s other two major scheduled variants, the J 32B all-weather fighter and the photo reconnaissance S 32C, optimized for maritime operations.

 

The idea behind the J 32 originated from the late 1940s: Even before the SAAB 29 Tunnan had taken to the air, discussions began between SAAB and the Swedish Aviation Administration regarding a future night fighter aircraft with a jet engine. Since the end of the war, the Swedish Air Force had wanted a night fighter aircraft but was forced to put these on the shelf due to cost reasons. In the end, they managed to obtain sixty de Haviland Mosquito night fighter aircraft (then designated J 30) from Great Britain as a low-budget solution, but the J 30 was far from modern at the end of the 1940s and talks with SAAB regarding a domestic alternative continued.

At the beginning of the 1950s, the Fpl 32 project was in full swing and the aircraft was selected as the basis for an indigenous all-weather jet night fighter with a sighting radar and various heavier weapons to be able to shoot down bombers – at the time of the J 32B’s design, the main bomber threat was expected to enter Swedish airspace at subsonic speed and at high altitude. The original idea was that this aircraft would replace the J 30 Mosquito from 1955 onwards, but this proved to be impossible as the J 30 fleet needed to be replaced long before this and the A 32A as initial/main varia of the Fpl 32 had priority. Because of this operational gap, in January 1951 the Swedish Air Force ordered the British de Haviland Venom (then designated J 33) as an interim all-weather fighter and plans for the J 32B were postponed until later with the idea that the Lansen’s fighter variant would replace the J 33 at the end of the 1950s and benefit from technological progress until then.

 

On 7 January 1957, the first J 32B conducted its maiden flight, and it was a considerable step forward from the A 32A attack aircraft – in fact, excepts for the hull, it had only little in common with the attack variant! The new fighter version was powered by a Rolls-Royce Avon Mk 47A (locally designated RM6A) which gave as much thrust without an afterburner as the SAAB A 32A's original RM5A2 did with an afterburner, greatly improving the aircraft’s rate of climb and acceleration, even though the J 32B remained only transonic.

The armament consisted of four heavier fixed 30 mm ADEN m/55 automatic cannon in a slightly re-contoured nose, plus Rb 24/AIM-9B Sidewinder IR-guided AAMs and various unguided rockets against air and ground targets. Instead of the A 32A’s Ericsson mapping and navigation radar, which was compatible with the indigenous Rb 04C anti-ship missile, one of the earliest cruise missiles in western service, the J 32B carried a PS-42/A. This was a search/tracking X-band radar with a gyro-stabilized antenna with a swivel range of 60° to each side and +60°/−30° up/down. The radar featured the option of a 3D display for both WSO and pilot and its data could be directly displayed in the pilot’s Sikte 6A HUD, a very modern solution at the time.

 

A total of 118 aircraft (S/N 32501-32620) were produced between 1958 and 1960, serving in four fighter units. However, the J 32B only served for just under 12 years as a fighter aircraft in the Swedish Air Force: aviation technology progressed very quickly during the 1960s and already in 1966, the J 32B began to be replaced by the J 35F, which itself was already an advanced all-weather interceptor version of the supersonic Draken. In 1969 only the Jämtland's Air Flotilla (F4) still had the J 32B left in service and the type began to be completely retired from frontline service. In 1970 the plane flew in service for the last time and in 1973 the J 32B was officially phased out of the air force, and scrapping began in 1974.

 

However, the J 32Bs’ career was not over yet: At the beginning of the 1970s, Målflygdivisionen (MFD for short, the “Target Air Division”) was still using old J 29Fs as target tugs and for other training purposes, and they needed to be replaced. The choice fell on the much more capable, robust and readily available J 32B. Twenty-four machines were transferred to the MFD in 1971 to be used for training purposes, losing their radar and cannon armament. Six of these six J 32Bs were in 1972 modified into dedicated target tugs under the designation J 32D, six more J 32Bs were left unmodified and allocated to various second-line tasks such as radio testing and ground training.

The other twelve J 32Bs (s/n 32507, -510, -512, -515, -529, -541, -543, -569, -571, -592, -607 and -612) became jamming aircraft through the implementation of ECR equipment under the designation J 32E. This electronics package included internally:

- An INGEBORG signal reconnaissance receiver with antennae in the radome,

covering S, C and L radar frequency bands

- A G24 jamming transmitter, also with its antenna in the radome, covering alternatively

S, C and L frequency bands. This device co-operated with the external ADRIAN jamming pod

- Apparatus 91B; a broadband jammer, later integrated with INGEBORG

- MORE, a jammer and search station for the VHF and UHF bands

- FB-6 tape player/recorder; used, among other things, to send false messages/interference

Additional, external equipment included:

- PETRUS: jamming pod, X-band, also radar warning, intended for jamming aircraft

and active missile radars

- ADRIAN: jamming pod, active on S- and C-band, intended for jamming land-based and

shipboard radars

- BOZ-1, -3, -9 and -100 chaff dispenser pods

 

Outwardly, the J 32E differed from its brethren only through some blade antennae around the hull, and they initially retained the fighters’ blue-green paint scheme and their tactical markings so that they were hard to distinguish from the original fighters. Over time, orange day-glow markings were added to improve visibility during training sessions. However, during the mid-Nineties, three machines received during scheduled overhauls a new all-grey low-visibility camouflage with toned-down markings, and they received the “16M” unit identifier – the only MFD aircraft to carry these openly.

 

When a J 32E crashed in 1975, three of the remaining six training J 32Bs were modified into J 32Es in 1979 to fill the ranks. The MFD kept operating the small J 32Ds and Es fleet well into the Nineties and the special unit survived two flotilla and four defense engagements. At that time, the Målflygdivisionen was part of the Swedish Air Force’s Upplands Flygflottilj (F16), but it was based at Malmen air base near Linköpping (where the Swedish Air Force’s Försökscentralen was located, too) as a detachment unit and therefore the machines received the unit identifier “F16M”, even though the “M” suffix did normally not appear on the aircraft. However, through a defense ministry decision in 1996 the Target Air Division and its associated companies as well as the aircraft workshop at Malmen were to be decommissioned, what meant the end of the whole unit. On June 26, 1997, a ceremony was held over the disbandment of the division, where, among other things, twelve J 32Es made a formation flight over Östergötland.

After the decommissioning of the division, however, the Lansens were still not ‘dead’ yet: the J 32D target tugs were kept operational by a private operator and received civil registrations, and eight flightworthy J 32Es were passed over to FMV:Prov (Provningsavdelningen vid Försvarets materielverk, the material testing department of the Swedish Air Force’s Försökscentralen) to serve on, while other airframes without any more future potential were handed over to museums as exhibition pieces, or eventually scrapped. The surviving J 32Es served on in the electronic aggressor/trainer role until 1999 when they were finally replaced by ten modified Sk 37E Viggen two-seaters, after their development and conversion had taken longer than expected.

 

However, this was still not the end of the Saab 32, which turned out to be even more long-lived: By 2010, at least two Lansens were still operational, having the sole task of taking high altitude air samples for research purposes in collaboration with the Swedish Radiation Safety Authority, and by 2012 a total of three Lansens reportedly remained in active service in Sweden.

The kit and its assembly:

This is a what-if project that I had on my idea list for a long time, but never got the nerve to do it because it is just a mild modification – the model depicts a real aircraft type, just with a fictional livery for it (see below).

The plan to create a J 32E from Heller’s A 32 kit from 1982 predated any OOB option, though. Tarangus has been offering a dedicated J 32B/E kit since 2016, but I stuck to my original plan to convert a Heller fighter bomber which I had in The Stash™, anyway)- also because I find the Tarangus kit prohibitively expensive (for what you get), even though it might have saved some work.

 

The Heller A 32A kit was basically built OOB, even though changing it into a J 32B (and even further into an “E”) called for some major modifications. These could have been scratched, but out of convenience I invested into a dedicated Maestro Models conversion set that offers resin replacements for a modified gun bay (which has more pronounced “cheek fairings” than the attack aircraft, the lower section is similar to the S 32C camera nose), a new jet exhaust and also the Lansen’s unique conformal belly tank – for the cost of a NIB Heller Saab 32 kit alone, though… :-/

Implanting the Maestro Models parts was straightforward and relatively easy. The J 32B gun bay replaces the OOB parts from the Heller kit, fits well and does not require more PSR than the original part. Since the model depicts a gun-less J 32E, I faired the gun ports over.

 

The RM6A exhaust was a bit more challenging – it is a bit longer and wider than the A 32A’s RM5. It’s not much, maybe 1mm in each dimension, so that the tail opening had to be widened and slightly re-contoured to accept the new one-piece resin pipe. The belly tank matched the kit’s ventral contours well. As an extra, the Maestro Models set also offers the J 32B’s different tail skid, which is placed further back on the fighter than on the attack and recce aircraft.

 

The J 32E’s characteristic collection of sizable blade antennae all around the hull was scratched from 0.5 mm styrene sheet. Furthermore, the flaps were lowered, an emergency fuel outlet was added under the tail, the canopy (very clear, but quite thick!) cut into two parts for optional open display, and the air intake walls were extended inside of the fuselage with styrene sheet.

 

Under the wings, four pylons (the Heller kit unfortunately comes totally devoid of any ordnance or even hardpoints!) from the spares box were added that carry scratched BOZ-1 chaff dispensers and a pair of ADRIAN/PETRUS ECM pod dummies – all made from drop tanks, incidentally from Swedish aircraft (Mistercraft Saab 35 and Matchbox Saab 29). Sure, there are short-run aftermarket sets for this special equipment that might come closer to the real thing(s), but I do not think that the (quite considerable) investments in all these exotic aftermarket items are worthwhile when most of them are pretty easy to scratch.

 

 

Painting and markings:

The paint scheme was the actual reason to build a J 32E: the fundamental plan was to build a Lansen in the Swedish air superiority low-viz two-tone paint scheme from the Nineties, and the IMHO only sensible option beyond pure fantasy was the real J 32E as “canvas”. I used JAS 39 Gripens as reference: their upper tone is called Pansargrå 5431-17M (“Tank Grey”, which is, according to trustworthy sources, very close to FS 36173, U.S. Neutral Grey), while the undersides are painted in Duvagrå 5431-14M (“Dove Grey”; approximately FS 36373, a tone called “High Low Visibility Light Grey”). Surprisingly, other Swedish types in low-viz livery used different shades; the JA 37s and late J 35Js were painted in tones called mörkgrå 033M and grå 032M, even though AJSF 37s and AFAIK a single SK 37 were painted with the Gripen colors, too.

 

After checking a lot of Gripen pictures I selected different tones, though, because the greys appear much lighter in real life, esp. on the lower surfaces. I ended up with FS 36231 (Dark Gull Grey, Humbrol 140, a bit lighter than the Neutral Grey) and RLM 63 (Lichtgrau, Testors 2077, a very pale and cold tone). The aircraft received a low waterline with a blurry edge, and the light grey was raised at the nose up to the radome, as seen on JA 37s and JAS 39s. To make the low-viz Lansen look a little less uniform I painted the lower rear section of the fuselage in Revell 91 and 99, simulating bare metal – a measure that had been done with many Lansens because leaking fuel and oil from the engine bay would wash off any paint in this area, leaving a rather tatty look. Di-electric fairings like the nose radome and the fin tip were painted with a brownish light grey (Revell 75) instead of black, reducing contrast and simulating bare and worn fiber glass. Small details like the white tips of the small wing fences and the underwing pylons were adapted from real-world Lansens.

 

After a light black ink wash, I emphasized single panels with Humbrol 125 and 165 on the upper surfaces and 147 and 196 underneath. Additionally, grinded graphite was used for weathering and a grimy look – an effective method, thanks to the kit’s fine raised panel lines. The silver wing leading edges were created with decal sheet material and not painted, a clean and convenient solution that avoids masking mess.

 

The ECM and chaff dispenser pods were painted in a slightly different shade of grey (FS 36440, Humbrol 40). As a subtle contrast the conformal belly tank was painted with Humbrol 247 (RLM 76), a tone that comes close to the Lansens’ standard camouflage from the Sixties’ green/blue livery, with a darker front end (Humbrol 145) and a bare metal tail section.

 

The cockpit interior was, according to pictures of real aircraft, painted in a greenish grey; I used Revell 67 (RAL 7009, Grüngrau) for most surfaces and slightly darker Humbrol 163 for dashboards and instrument panels. The landing gear wells as well as the flaps’ interior became Aluminum Bronze (Humbrol 56), while the landing gear struts were painted in a bluish dark green (Humbrol 195) with olive drab (Revell 46) wheel hubs - a detail seen on some real-life Saab 32s and a nice contrast to the light grey all around.

 

All markings/decals came from RBD Studio/Moose Republic aftermarket sheets for Saab 32 and 37. From the latter the low-viz national markings and the day-glo orange tactical codes were taken, while most stencils came from the Lansen sheet. Unfortunately, the Heller kit’s OOB sheet is pretty minimalistic – but the real A/S 32s did not carry many markings, anyway. Finally, the kit was sealed with matt acrylic varnish. As a confusing detail I gave the aircraft an explicit “16M” unit identifier, created with single black 4 mm letters/numbers. As a stark contrast and a modern peace-time element I also gave the Lansen the typical huge day-glo orange tactical codes on the upper wings that were carried by the Swedish interceptors of the time.

 

 

A relatively simple build, thanks to the resin conversion set – otherwise, creating a more or less believable J 32E from Heller’s A 32 kit is a tough challenge. Though expensive, the parts fit and work well, and I’d recommend the set, because the shape of the J 32B’s lower nose is quite complex and scratching the bigger jet pipe needs a proper basis. The modern low-viz livery suits the vintage yet elegant Lansen well, even though it reveals the aircraft’s bulk and size; in all-grey, the Lansen has something shark- or even whale-ish to it? The aircraft/livery combo looks pretty exotic, but not uncredible - like a proven war horse.
