It is possible to build either of the two Ju 390s using two Revell of Germany Ju 290 kits. In this case I’ll be building the V2 maritime patrol aircraft. This conversion is fairly straight-forward, and is easier than it might first appear. There is obviously a bit of sawing to be done, but the parts generally mate back with others of identical lines and cross sections. Piece of cake, right? Revell has boxed A-5 and A-7 versions of the Ju 290, either kit can be used for conversions as the required solid nose is in both boxes. One benefit of using the A-7 version is there is an extra sprue with three Hs 293 anti-ship missiles for the spares box. These are nice kits, but there are a few inaccuracies which I’ll point out as I go along.
I first became interested in the Ju 390 after reading about its history in William Green’s Warplanes of the Third Reich. When Revell of Germany released their 1/72 scale Ju 290 kits, 390 conversions became an attractive, and affordable, possibility for modelers. The Ju 390 was a development of Junkers’ previous Ju 290 series, which themselves were extensions of the Ju 90 design. Green gives a detailed description of the modifications made to transform existing Ju 290 airframes to Ju 390 standard and lists the equipment they carried.
References are an issue, there is just not that much material on the Ju 390. Fortunately, most of the design details were consistent with the Ju 290s, and much of the operational history of the Ju 390 V2 parallels the 290s which were operated by the same units. In addition to Green, Monogram Close-Up 3 Junkers 290 provides many pictures useful for modelers.
There are only seven known pictures of the V1, and just one purporting to be the V2. I say purporting because the picture shows several obvious indications of tampering, and does not match the general description of the V2 given by Green. There are three different versions of this picture on the Internet, all doctored in different ways.
If you want to model a Ju 390, there are several versions and paint schemes from which to choose:
V1 (factory code GH + UK) – This was the development aircraft for the transport version. Some sources state that a Ju 90 was used as the basic airframe for the conversion, and the fuselage had round cabin windows consistent with this. The fuselage aft of the wing was extended 8.07 feet, and the wings were extended 27.23 feet, bringing the total span to 165.02 feet, which is 27.5 inches (69.9 cm) in 1/72 scale! For a transport, camouflage was the standard 70 / 71 over 65 scheme. This aircraft appears to have spent its days conducting various tests and trials, including serving as an aerial tanker for Ju 290s. It ended the war on an airfield in Czechoslovakia, without propellers. Planet Models makes a resin kit of this aircraft, but it is very, very expensive.
V2 (factory code RC + DA) – This was the development aircraft for the maritime reconnaissance version. The main structure was modified the same as the V1, except an additional 8.2 foot section was added to the forward fuselage. Various reconstructions show the fuselage with either round or rectangular windows – your choice. This aircraft was fitted with a ventral gondola, FuG 200 radar, and full defensive armament. It was completed in October of 1943, and delivered to FaG 5 (codes 9V + xx) at Mont de Marsan in France. Several sources state that this aircraft flew to within 12 miles of New York in January 1944, although this is disputed by others. Ju 290 maritime patrol aircraft carried a high-demarcation 72 / 73 over 65 scheme.
FaG 5 was disbanded in August 1944 when German airbases in France were threatened by the Allied advance. FaG’s Ju 290s were passed to KG 200, a Luftwaffe special missions unit (KG 200’s assigned codes were A3 + xx, some aircraft were repainted to this, some to other codes). Pictures show at least a few were given additional mottles of dark greens on the fuselage sides – see the cover photograph on the Monogram Close-Up. Color photographs of the captured Ju 290 A-7 “Alles Kaputt” of KG 200 brought to Freeman Field by Col. Watson show it carried black undersides, while upper surfaces were RLM 83 Light Green with 81 Brown Violet spots. So, there a few possible alternative camouflage and marking options to model the V2 in later service.
Several interesting missions are attributed to the Ju 390, including liaison flights to Japan. While confirmation is lacking (not surprising for a special ops unit), Ju 290A-9s are known to have completed many of the same assignments. The V2 was reported to be standing by at Recklin to evacuate Nazi VIPs to Spain in April of 1945. While a Ju 290A-5 (W.Nr. 110178) actually made the flight to Spain, the V2 was not reported to have been located after the war. One account says the V2 was flown to Norway, where it was repainted in Swedish colors, and then used to transport German scientists to a ranch in Paysandu Province, Uruguay. The aircraft was then supposedly dismantled and sunk in the Rio Uruguay River, where it is said to remain to this day. A mystery.
V3 – This was to be the Amerika Bomber Ju 390A development aircraft, but it was never built. Dimensions were to have been the same as the V2, but defensive armament was to have been increased. The bomb load was to have been carried externally. Camouflage could be anything carried by German bombers during the last year of the war, so there are several interesting possibilities.
A Luft ’46 project is a proposed reconnaissance version with wings extended to 181.63 feet. This was a Paperwaffe project only, and I’ve never even found general configuration drawings of this one.
Ki-390 – This one is definitely a Nippon ’46 “what if”. Considerable interest in the Ju 390 design was expressed by the Imperial Japanese Army Air Force, the JAAF even purchasing manufacturing rights. However, the design was never developed. Anybody up for a kitbash using engine nacelles and armament from the Hasegawa Rita? I’d be lying if I said I haven’t thought about it!
This is ESCI’s M6 Gun Motor Carriage, I believe this is the only kit made of this vehicle in our scale. An old kit, and not an easy build. Just about every piece had an ejector pin mark or mold seam somewhere, and there are fit issues with several of the parts. One thing to watch for is the rear suspension sits way too high, mount the rear springs to the bottom of the bed instead of the frame and the sit is much improved.
Grunt: The Curious Science of Humans at War
By Mary Roach
Hardcover in dustjacket, 288 pages
Publisher: W. W. Norton & Company June 2016
Dimensions: 6 x 1.1 x 8.6 inches
Warfare is a parade of the absurd, and Mary Roach loves a parade. In this book she takes a humorous look at the peculiar topic of military science, or more specifically the science of human physiology in the U.S. military. Roach does not pull any punches either, topics covered in depth include the use of cadavers in research and testing, the medical uses of maggots, and penile transplants. The absurdities of the bureaucratic controls on the researchers are not lost on her, and she writes with a very readable style, tongue firmly lodged in cheek.
While often funny, Roach clearly understands the science behind the research and does an excellent job communicating that to the reader. She presents one of the best explanations of how heat stress affects the human body I have read. She also treats the scientists and military personnel she interviews with respect. She has a way of preserving her subjects’ personal dignity while exploring undignified topics in a humorous manner.
I bought this book for a pittance at Half Price Books, one of my all too frequent impulse buys. I’m glad I read it, and can recommend it as an entertaining look into the science behind people in the military.
