Some background:
The Boeing B-52 Stratofortress is a long-range, subsonic, jet-powered strategic bomber, designed and built by Boeing, which has continued to provide support and upgrades.
Beginning with the successful contract bid in June 1946, the B-52 design evolved from a straight wing aircraft powered by six turboprop engines to the final prototype YB-52 with eight turbojet engines and swept wings. The B-52 took its maiden flight in April 1952. Built to carry nuclear weapons for Cold War-era deterrence missions by the United States Air Force (USAF), the B-52 Stratofortress replaced the Convair B-36. A veteran of several wars, the B-52 has dropped only conventional munitions in combat, capable of carrying up to 70,000 pounds (32,000 kg) of weapons.
The B-52 has been in active service with the USAF since 1955. The bombers flew under the Strategic Air Command (SAC) until it was inactivated in 1992 and its aircraft absorbed into the Air Combat Command (ACC). In 2010 all B-52 Stratofortresses were transferred from the ACC to the new Air Force Global Strike Command (AFGSC).
Superior performance at high subsonic speeds and relatively low operating costs have kept the B-52 in service despite the advent of later, more advanced aircraft, including the canceled Mach 3 B-70 Valkyrie, the variable-geometry B-1 Lancer, and the stealth B-2 Spirit. The B-52 has so far completed sixty years of continuous service with its original operator, and after being upgraded between 2013 and 2015, it is expected to serve with the USAF even into the 2040s, maybe even beyond that.
The only foreign operator of the B-52 had been the Royal Air Force in the 1980ies and 19990ies, and just in a small number. After the USAF's retirement of the earlier B-52 types, the remaining G and H models were used for nuclear standby ("alert") duty as part of the United States' nuclear triad. This triad was the combination of nuclear-armed land-based missiles, submarine-based missiles and manned bombers.
After the end of the Falkland War, the Royal Air Force withdrew its final long-range bomber type, the Avro Vulcan - which was to be replaced by the MRCA Tornado which was designed to a totally different tactical profile. Fearing the loss of international influence, the Ministry of Defence decided to fill this gap and leased twelve revamped and heavily modified B-52Gs from the USA. This was a convenient deal for both sides, since these bombers were earmarked to be scrapped per the terms of the Strategic Arms Reduction Treaty (START).
These modified aircraft were designated B-52K by Boeing, while the RAF officially called them later in service Stratofortress B.I, even though B-52K was more common. Most obvious change was the introduction of new engines. The B-52K benefited from a Boeing study for the U.S. Air Force in the mid-1970s which investigated replacing the original TF33 engines, changing to a new wing, and other improvements to upgrade B-52G/H aircraft as an alternative to the B-1A, then in development. Boeing had suggested re-engining the complete USAF B-52 fleet with four Rolls-Royce RB211 535E-4 each. The RB211 had originally been developed for the Lockheed L-1011 TriStar in the early 1970ies, but also saw use with several Boeing airliners, the "535" being a special development for the 757 airliner.
This new, bigger engine would not only improve overall weight and power (total thrust 8× 17,000 lb vs .4× 37,400 lb), it would also increase range and reduce fuel consumption and simplify the whole aircraft. Despite these direct benefits the USAF did not opt for this offer: the costs for aircraft modifications, infrastructure, logistics and also for the running operations of the complete fleet would have been prohibitively high, as well as only a partial conversion. For the UK, where the weapon system was to be introduced from scratch and also on a much smaller scale, the update made sense, though.
Boeing supported the British project, since the company expected to present the UK conversion as a field case study for potential later large-scale sales to the USAF. This included extensive wind tunnel testing, in order to optimize the engine pylons. These tests also demonstrated that the new four-engined aircraft may not have enough rudder authority to counter the adverse yaw generated by an outboard engine-out scenario. As a consequence, an enlarged fin was (re-)introduced, even though it was different from the earlier B-52 variants. Actually, as a cost saving measure, fin elements from the Boeing 747 airliner were used - and its integral tank enhanced the overall fuel capacity even further.
The ex-USAF B-52Gs converted into K models were taken from surplus stock that not been modified into cruise missile carriers, they were rather conventional bombers with nuclear capabilities - its main purpose for the RAF. A secondary role were martime operations like mine laying or missile attacks against surface ships over long distances.
Hence, the RAF aircraft underwent a series of modifications to improve conventional bombing and to adapt them to RAF standards. They were fitted with a new Integrated Conventional Stores Management System (ICSMS) and new underwing pylons that could hold larger bombs or other stores, including up to twelve AGM-84 Harpoon anti-ship missiles. The B-52K also introduced new radios, integrated Global Positioning System into the aircraft's navigation system and replaced. The under-nose FLIR was retained, even though with a modernized system. A fixed refluelling probe for the RAF's drogue system was installed on top of the cockpit section (earn ing the B-52K the nickname "unicorn"), and the tail gun station was deleted and replaced with ECM equipment and flare/chaff dispensers.
Delivery started in 1990, and the B-52K was just too late to become operational during the First Gulf War (Operation Desert Storm), in which RAF Tornados took part in, though, as well as USAF B-52s. In fact, the modified BUFF took three years to become fully operational, despite - or perhaps because of - the small fleet. In parallel, the Tornado was gradually introduced, too.
Eventually, the B-52Ks were baptized with fire: in 1999, when 'Operation Allied Force' began and USAF and RAF bombers bombarded Serb targets throughout the Federal Republic of Yugoslavia - even though with mixed success, since more than 600 of the 1.000 bombs dropped by the RAF during the Kosovo conflict missed their target, the Ministry of Defence admitted in 2000.
In 2003 the B-52Ks also took part in the invasion of Iraq as part of 'Operation Telic'. The Iraqi Forces were unable to mobilize their air force to attempt a defense, and the U.S. Air Force, Marine Corps and Naval Aviation, as well as the Royal Air Force, operated with impunity throughout the country, pinpointing heavily defended resistance targets and destroying them before ground troops arrived.
This success reinstated the B-52K's performance reputation a little, but could not deny the fact that the global political situation had changed since the fall of the Soviet Union, and that the heavy bomber was a concept of the past. Furthermore, the changing character of conflicts and the respective mission profiles made the British MoD in 2004 decide to retire the small, costly B-52K fleet, of which four aircraft had already to be grounded due to the end of their airframe lifetime. Consequently, all B-52Ks were scrapped until 2005.
Besides, the program results did not change the USAF's decision to keep the B-52H with its eight engine layout in service.

The kit and its assembly:
I remember that I read about the re-engine project of the USAF's late B-52 versions when I was in school, many years ago, and the BUFF is still flying - even though in its original eight engine layout. Anyway, I wonder why this topic has not been adopted by modelers more often? O.K., a B-52 is a large aircraft, but there are good small scale version around, like the Dragon kit in 1:200 which I converted.
Work was pretty straightforward, and the basis is/was a B-52G. The kit was built almost OOB, only mods include:
- engine nacelles from a Hasegawa Boeing 747-400
- the upper section of the latter's fin, too
- a scratched refuelling probe
- a modified tail without the four machine guns
Fit is good and surface structure/details are more than satisfactory for a kit of this small scale. Only thing that bugged me was the slightly tinted canopy that is a bit too wide for the fuselage, it's hard to blend it into the rest of the body. Another building horror were the 24 itsy-tiny bombs for the quadruple MERs under the wings.
Integrating the Jumbo nacelles was easier than expected, even though, after finishing the conversion, I'd recommend reducing the height of the outer pyolns by 2-3 mm, so that the engines come higher and closer to the wings. Space to the ground is very little - and to mend this I lengthened the outrigger wheels slightly.
Another issue were the wing parts - the left wing was slightly warped, upwards, and even though I tried to bend and force it into a stright line it somehow move back into its original position, so that a B-52 on the ground was hard to realize. If you build one, tuck the landing gear up and put it on a stand. It looks better, anyway... ;)
Painting and markings
This was the fun part. A B-52 with four bigher jet engines is one thing, and at first I intended to create a contemporary USAF aircraft. But then I remembered the weird Hemp apint scheme for large RAF birds like the Nimrod, VC.10 or Tristar tankers, and I wondered if that could not be applied to a B-52 in "foreign service"...?
Said and done, and from there things unfolded in a straightforward fashion. The only consequence of the RAF as useer was the refuelling probe, and the 340kg iron bombs that came as ordnance with the kit were a welcome option, too.
Even though Hemp is available from Humbrol (168) I rather used a darker tone, 187. Hemp was later used for shading, though. The undersides were painted in Barley Grey (Humbrol 167) and shaded with Light Ghost Grey (FS 36375, Humbrol 127), after a light wash with highly thinned black ink. Radomes and antennae received a yellow-ish, beige finish, the landing gear and the air intakes were painted white, as well as the MERs.
Decals come from several kits, e .g. a Cyber Hobby 1:200 Vulcan, a Matchbox Hawk 200 and a Tornado sheet from the Operation Allied Force era (the nose art was taken from there, as well as the ZA447 code).
A relatively simple whif - the large engine nacelles look strange and demonstrate how slender the B-52's body actually is, compared with an airliner. But the Hemp/Grey livery suits it very well, and the pics taken from above show how effective this scheme is when the aircraft is parked on a concrete airfield - and it is even effective in the air!
Ex-British Railways Bulleid 'Battle of Britain' class pacific locomotive Nº 34081 92 SQUADRON, is named after the famous Spitfire squadron based at Biggin Hill during the Battle of Britain in 1940. Entering service from Brighton works in September 1948, her all-too-brief mainline career ended when she was withdrawn from Eastleigh shed in August 1964 and subsequently sold to Dai Woodhams scrap yard at Barry Island in South Wales.
Purchased from there by the then-named Battle of Britain Locomotive Preservation Society in autumn 1973, she arrived at Wansford on the Nene Valley Railway near Peterborough on 7th December 1976 where restoration commenced. In 1998, some 22 years later she moved under her own power at the NVR for the first time since 1964 and became a regular performer on various Heritage Railways until being withdrawn for overhaul at the North Nofolk Railway in May 2008. 34081 returned to service on the Nene Valley Railway in February 2017 during the special Bullied Gala event.
The locomotive is seen running "light engine" at Wansford.

More car show, hot rods, and chrome. The object of these cars is to create something that both functions (in a limited way) and is an quasi-art object. Hundreds, probably thousands of hours of labor went into building this hot rod engine that delivers maximum bling-----chrome hose, rocker arm covers, carburetor, all blinding shiny, perfectly fit and pristine. For me it's interesting, odd, and strangely beautiful stuff. I wanted a crop that would slightly disorient the viewer, so as not to focus on the forms as specific engine parts, but as light, light, line, color and reflection. Not too sure about this. . .wanted the feel of photorealistic painting or pop art. . .just something I wanted to try!
