Early 1943 the departement "Technische Luftrüstung" led by Dr. Benecke proposed a new type Torpedo
and developed and tested it at the Researchinstitute "Graf Zeppelin. The so called "BombenTorpedo" is
unpowered Torpedo which was dropped in a low angle. This new developed Torpedo could be build in
shortest time , much cheaper and resource saving. No expensive PowerUnit was needed.
Developed, built and tested had been:
BT 200 / BT 400 / BT 700a / BT 700 b / BT 1000 / BT 1400 / BT 1850
It is reported that Fw 190 F-8/R16 equiped with BT-700 flew night attacks against British ships from
Stavanger airfield / Norway. However this claim can not be substantiated.
