In an effort to overcome the problems being experienced with the coupled DB 606 engines of the He 177, Heinkel suggested in 1940 that four separate DB 603s should be substituted. Although the Reichsluftfahrtsinisterium rejected the plan, work continued unofficially under the designation He 177B and the design was resurrected in response to Hitler's May 1943 demand for a heavy bomber to facilitate effective strikes on London. Converted from an He 177A-3/R2 airframe, with four DB 603A engines, the first Heinkel He 277 prototype flew at Vienna-Schwechat in the closing months of 1943, followed by the second aircraft on 28 February 1944. Directional instability resulted in the fitting of a twin fin and rudder tail unittothe
third prototype. Eight 1305kW DB 603A-powered He 277B-5/R2
production models were completed
before the priority given to fighter production in July 1944 brought the programme to an end.

| Simon Gunson, symngun=gmail.com, 05.05.2010 Correction Luft Archiv.de have a photo of the aircraft which you refer to Steve from the side and the Stamkennzeichen is NE+OD which would be a factory code for the first prototype. That codes identified for 6 airframes now. | | Simon Gunson, symngun=gmail.com, 05.05.2010 Hi Steve,
The aircraft with "N" is likely to have been GA+QN.
There were possibly as many as 26 He-277 produced. If you go online you may find a photo of one bombed out at Cheb airfield Czechoslovakia in 1945. Stamkennzeichen which I can identify include:
GA+QQ Heinkel He277 V9
GA+QR Heinkel He277 V10
GA+QM Heinkel He277 V26
GA+QX Heinkel He277 V18
GA+QQ Heinkel He277 V9 | | d.jay, 12.07.2009 This aircraft could have been the german Lancaster. Thousand bomber raids over london ? luckly it was too late in development. | | Simon Gunson, NZ, simongunson=paradise.net.nz, 22.05.2009 Some sources give W.Nr.535550 as a prototype He-277 but conflict whether it was the first or third prototype. The first was a single fin aircraft. The third was a twin fin. It's code was NN+QQ.
W.Nr.535550 (above) and Heinkel He277 GA+QQ (former He177 A-08 W.Nr.23 previously coded DL+AT are the only two records of He-277 which I can locate.
There are various claims that only 5 were built. Other claims that 8 were built. Given the lack of records or conflicting records it's hard to identify. Good luck. | | Steve Woodward, steve_woodwar84=hotmail.com, 04.10.2008 Can anyone tell me what the factory call-sign codes (stamkennzeichen)were on either of the He177B single-fin aircraft please? I want to model this aircraft but can find no photo showing all four letters. The pic on this site shows a "N" outer starboard wing but no more.
Thanks to anyone who can help. |
