[2] The missile is known as Anti-Navire Léger (ANL) in France and Sea Venom (formerly "Future Anti-Surface Guided Weapon (Heavy)") in the United Kingdom.

[3][4][5][6][7] The first test launch, from an AS365 Dauphin helicopter of the French DGA, was successfully conducted on 21 June 2017.

With its 30 kg warhead, the missile is also capable of inflicting significant damage to larger vessels through precision aim point selection, and can also attack static land-based targets.

"[10] Sea Venom uses an infrared seeker with the option of "man in the loop" track-via-missile guidance via data-link;[2] the high speed two-way data-link transmits the images "seen" by the seeker back to the operator, enabling them to remain in control of the missile throughout its flight in addition to having an autonomous engagement capability.

The missile equipped four Wildcat HMA2 helicopters embarked on the strike group's accompanying destroyers.
