Heinkel He-177 Greif

The Heinkel He-177 Greif was Germany’s primary long-range heavy bomber during World War II, utilized extensively on the Eastern Front, in Operation Steinbock (1944) against the UK, and for anti-shipping missions in the Atlantic and Mediterranean. Despite high engine failure rates, it was used for mass raids near Velikiye Luki and supplied encircled forces. 
 
Key details regarding the usage of the He-177 include:
Eastern Front: Primarily used here, where its range was beneficial, and it conducted low-level missions against Soviet armor.
Operation Steinbock (1944): Participated in the "Baby Blitz" against London, with early deployments from France and later redeployments.
Anti-shipping (Atlantic/Mediterranean): Used in 1943–1944 for maritime, anti-shipping attacks in the Atlantic and in the Mediterranean.
Operational Role: Known for its high, and often fatal, engine overheating issues, leading to nicknames like "Flaming Coffin".
Other Potential Uses: Late-war, an upgraded version (A7) was discussed for long-range, one-way missions, including potential, though speculative, transatlantic flights. 
 
Approximately 1,100+ He-177s were produced, with notable use by units like KG 50 and II./KG 100.
