Comments
Arguably the largest bomber built by the Germans, the He 177 suffered many flaws and turned into one of the Luftwaffe's biggest failures (when compare service use to the amount of resources invested.) A significant problem that plagued the program from the beginning was a ludicrous requirement that this extremely large aircraft be capable of dive bombing. This combined with the attempt to reduce drag by coupling the engines, while theoretically sound, proved to be impossible in practice for no aircraft in history had engines that would so readily burst into flame. 75% of the prototypes crashed and a good percentage of the 35 A-0 pre-production airframes were written off in crashed or in-flight fires.
About 700 served on the eastern front using 50mm and 75mm guns for tank-busting while a few brave aircrews ineffectually bombed England.
The He 177 proved to be such a big problem that Goering forbid Heinkel to develope a four engine version (though Heinkel did anyways, the result being the He 277).
