F21 Heavyweight Torpedo

The F21 heavyweight torpedo from DCNS is a dual-purpose torpedo that is effective against submarines and surface vessels. It will replace F17 mod2 torpedo aboard the French Navy's submarine fleet.
The 1.3t F21 can be integrated into all types of submarines including nuclear-powered SSBNs and SNs as well as diesel-electric types, and can be launched in swim-out or push-out modes. It incorporates a new-generation acoustic head from Thales Underwater System, in addition to an impact/acoustic fuse warhead.
The F21 can be operated in depth ranging from 10m to 500m and is driven by electric propulsion based on the silver oxide-aluminium (AgO-Al) primary battery providing a speed of 25kt to 50kt, range of over 50km and endurance of one hour.
