The He 111's low-level performance attracted the interest of the Kriegsmarine. The result was the He 111J, capable of carrying torpedoes and mines. However, the navy eventually dropped the program as they deemed the four-man crew too extravagant. The RLM continued production of the He 111 J-0. Some 90 (other sources claim 60) were built in 1938 and were then sent to Küstenfliegergruppe 806.  Powered by the DB 600G engines, it could carry a 2,000 kg payload. Only a few of the pre-production J-0s were fitted with the powerplant, the DB 600 was used, performance deteriorated and the torpedo bomber was not pursued. The J variants were used in training schools until 1944. Some J-1s were used as test beds for Blohm & Voss L 10  radio-guided air-to-ground torpedo missiles.
