History[]
Concept[]
The F21 was to be a development version of the Italian Black Shark torpedo. In 2008 France signed a development contract for 93 heavy torpedoes for its nuclear submarines, to be delivered from 2015.[3] The original plan called for a derivative of the Black Shark to be built by a joint venture between DCNS, Thales and WASS,[4] but they fell out and DCNS will now be developing the F21 Artemis with Thales and Atlas Elektronik.[3] The F21 shares similarities with the Black Shark, including an electric motor driven by an aluminium silver-oxide (AgO-Al) battery.[5] It will have a warhead of PBX B2211, range of 50 km (31 mi) and speed of 50 knots (93 km/h).[6] As of 2015[update] the project has a €485m budget with a unit cost of €2.3m (FY12), or €5.2m including development costs.[3]
Qualification[]
The F21 was first tested on DCNS's Pégase catamaran in February 2013 and a submarine launch is planned for 2014, with production deliveries scheduled to start in late 2015.[7] Qualification testing began in 2016, and were completed in June 2017 off the coast of Var.[1]
