Re: Blohm und Voss Ha 137 B-0
In the RLM Aircraft development programmes dated 01.10.1936 and 01.04.1937, the following information is given about the Ha 137 light dive bomber:
V-1 W.Nr. 107 engine: 1 x BMW 132. First flight in January 1935.
V-2 W.Nr. 108 engine: 1 x BMW 132. First flight in May 1935.
V-3 W.Nr. 109 engine: 1 x RR Kestrel. First flight in June 1935.
V-4 W.Nr. 183 engine: 1 x Jumo 210. First flight in November 1935.
It is said that all testing were cancelled as these aircraft would not be procured by the RLM. However, completed aircraft would be used as test beds for various equipment.
A series of 7 Ha 137A-0 with 1 x BMW 132 engines and reserved W.Nr. 184 - 190 were planned, as well as a series of 9 Ha 137B-0 with Jumo 210 engines and reserved W.Nr. 191 - 199 were also planned. How many that was acutally built, this source do not tell.
