Status of German Seaspike and equivalent lightweight ASW weapons?

[Jon K]

What is the current status of German-Norwegian Seaspike and other equivalent programs? (Seaspike is a very lightweight torpedo intended mostly to clarify whether detected sub contact is real or not)

[tatra]

It's probably not SeaSpike but SeaPike, the name of a fish. In German: SeeHecht. Previous versions called respectively called
DM1 Seeschlange (Sea Serpent)
DM2/DM2A1 Seeaal (Sea Eel, also referred to as Seal)
DM2A3 Seehecht (Sea Hake)
DM2A4 Improved Seehecht (Sea Pike?)
