The Blohm & Voss Bv 246 Hagelkorn (Hailstone) originally known as
Bv 226. Designed and developed by Blohm
in 1943 under the leadership of Dr.-Ing. Richard
The designation was changed to Bv 246 on 12 December 1943,
when production was started. The main idea for Bv 246 was to attack targets from
the air at a greater distance than the defending anti-aircraft guns, allowing
the bomb to glide to its target and allowing the carrier aircraft to escape.
The Bv 246 had a clean cigar shaped fuselage and a cruciform tail in early versions
and a double ventral tail mounted on the sides of a wide horizontal stabiliser.
In later versions. The wings were constructed of diecast concrete aerofoils with
a steel core. Although the concrete wings made the Bv 246 Hagelkorn extremely
heavy, it did manage a very acceptable glide angle of 25:1, allowing it a range
of 210 km if dropped from 10,500 m.
The Bv 246 was originally meant to
be guided by a radiolink from the carrier aircraft such as the He
, Fw 190
but the British had began successfully countering German radio navigational
aids and so the project was officially cancelled on the 26 February 1944, mainly
due to re-emphasising priorities within the German missile programme.
in 1945. There was renewed interest in the Bv 246 when it was used in tests with
a Radieschen (Radish) which was designed by Dr.-Ing. Kleinwächter. Ultrashort
wave, passive homing device, which would allow it to home in on enemy radar systems.
The Bv 246 had to be modified to fit the Radieschen into the nose compartment,
and acted on gyroscopic autopilot for the rudders and elevator. Ten Bv 246 were
fitted with Radieschen system and thoroughly tested out at Unterlüss artillery
range, of the ten only two managed to reach their target. The eight failures were
due to the gyroscopic autopilot, which was still under development. However the
two that did make it were extremely accurate. Even though 1,100 Bv 246 have been
produced none ever made operational use. The Blohm & Voss team were involved in
a number projects similar to the Bv 246 like the
of the Third Reich.
