Junkers Ju 390

Post by Cantankerous » 17 Aug 2020 04:51

If anyone is aware, the Junkers company in Dessau developed the Ju 390 as an enlarged version of the Ju 290 with six BMW 801 engines and a longer fuselage and greater wingspan. The Ju 390 was planned as a transport aircraft (Ju 390A-1) and maritime reconnaissance aircraft (Ju 390B-1), but also as a strategic bomber (Ju 390C). The first Ju 390 prototype (GH-UK) was made by taking a Ju 90 prototype and fitting it with an additional wing section and a new fuselage section behind the wings; it first flew on October 20, 1943, at Merseburg and was to be the prototype for the Ju 390A-1. The Ju 390 V2 was the planned prototype for the Ju 390B-1, and it would have featured a FuG 200 Hohentwiel ASV (Air to Surface Vessel) radar and defensive armament consisting of five 20 mm MG 151/20 cannons. An order was placed for 26 Ju 390A-1s, and the Ju 390 V2 was to be built by modifying one Ju 290 with an additional fuselage section and new wing section. However, by the time the RLM ordered a stop to all large combat aircraft programs in mid-1944, including the Ju 390, the second Ju 390 prototype was still under construction. The Ju 390 V1 was flown to Dessau and stripped of parts, finally being blown up by the Germans to prevent it from falling into Allied hands.

There was a rumor that the Ju 390 made a test flight to within 12 miles of New York to test the Ju 390's ability to attack Manhattan, but this claim is nothing more than pure fantasy and not backed up by documented evidence.

The possibility of a Ju390 wreck deserves some serious investigation

There are someinaccuracies in your summary,ie

Photos of the Ju390 in flight disclose two completed aircraft with different dimensions flew during WW2
one with Stkz markings RC+DA is often misidentified as the V2 prototype, however it is in fact the V1 aircraft

Image

The other aircraft with stkz markings GH +UK has a much longer fuselage

Image


bY flipping & rotating images of both aircraft, I can demonstrate which one was the V2 which it is known had a lengthened fuselage
