HISSTORY AND DEVELOPMEANT:
Spoiler
The He 177 B was the later, more developed version of the He 177 heavy bomber, intended to fix the severe problems of the original A-series. Its development began after the A-series showed major issues with its tandem engines and structural integrity, but its progress was hindered by Allied bombing raids on production facilities and Arado’s heavy involvement with its own advanced aircraft. The He 177 B was planned with a four-engine layout, which was more reliable, and saw prototypes begin flight testing in late 1943, but it never entered mass production before the end of the war.
The He 177A was Germany’s only operational heavy bomber but it was crippled by its coupled engine design (two engines bolted together per nacelle).
This caused chronic overheating, fires, and structural stress — earning it the nickname Luftwaffenfeuerzeug”* (Luftwaffe’s lighter).
By 1942, it was clear the A‑series could not fulfill the Luftwaffe’s strategic bomber role
The Redesign: Birth of the B‑Series
Spoiler
Heinkel proposed a clean redesign: the He 177B, with four separate Daimler‑Benz DB 603 engines in individual nacelles.
This solved the A‑series’ fatal flaw and aligned the aircraft with Allied heavy bombers (B‑17, Lancaster, B‑24).
Structural changes included:
Twin‑fin tail for stability.
Pressurized cockpit for high‑altitude operations.
Enlarged wingspan (~43 m) for greater lift and range.
Strengthened bomb bay** for very heavy ordnance
Why It Failed
Spoiler
Despite solving the A‑series’ problems, the B‑5 came too late:
By 1944, Germany’s strategic situation was collapsing.
The Luftwaffe shifted resources to fighters (Me 262, Ta 152) and “wonder weapons” (V‑1, V‑2).
Only a handful of B‑series prototypes were completed at Heinkel’s Vienna‑Schwechat plant.
A production order was penciled in for autumn 1944, but never realized.
