History

First flown in 1937, the BV 138 entered Luftwaffe service in 1940 after significant development problems with the original design. The definitive BV 138C-1 proved a capable long-range patrol aircraft, cooperating with U-boats in the Atlantic. Over 270 were built.

Variants

The BV 138A and B were early versions with various teething troubles; the BV 138C-1 was the main production variant with Junkers Jumo 205 diesel engines and improved armament. A minesweeping version carried large degaussing loops.

Where you'll see it

Operated by the Luftwaffe's maritime aviation units over the North Sea, Atlantic, and Arctic throughout the war. It worked in concert with U-boat wolf packs, relaying convoy positions. No examples are known to survive.
