French shipbuilder and defense contractor DCNS announced it has performed a “qualification firing” of the French Navy’s F21 heavyweight torpedo.

This move brings the torpedo another step closer to being fielded on the French submarines.

In addition to being fielded on the French new Barracuda-class nuclear submarines, the torpedo was expected to be ready for delivery to the navy for the entire fleet by 2016.

In an announcement from 2014, DCNS said a prototype of the weapon had been undergoing tests in the Mediterranean Sea since 2013.

The contract, under which DCNS was to deliver 93 of the torpedoes to the navy, was awarded by the French Defense Procurement Agency (DGA) in 2008.

The wire-guided torpedo is 6 meters long, weighs 1.5 tonnes and has a range of 50 kilometers traveling at speeds between 25 and 50 knots.

F21 is operated through the MIGAL fire control system which serves as the interface between the torpedo and the submarine’s combat information centre.

According to DCNS, the F21 will be fitted on the Brazilian Navy SSKs and is also launchable from ships.
