Hamburger Flugzeugbau Ha 137

what is it?

The Hamburger Flugzeugbau Ha 137 was a German ground-attack aircraft of the 1930s. It was Blohm & Voss' entry into the contest to equip the re-forming Luftwaffe with its first purpose-built dive bomber. Although the contest would eventually be won by the Junkers Ju 87, the Ha 137 demonstrated that B&V's Hamburger Flugzeugbau, not even two years old at this point, had a truly capable design team of its own.
