Sea Venom is an Anglo-French lightweight anti-ship missile developed by MBDA to equip the French Navy and the Royal Navy. 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. While initial operating capability had been expected with the Royal Navy in 2022, it was reported in 2023 that, due to “on-going integration challenges”, the Royal Navy's Wildcat helicopters would only achieve full operational capability with the missile in 2026.

The first test launch, from an AS365 Dauphin helicopter of the French DGA, was successfully conducted on 21 June 2017.

Initial operating capability for the missile with the Royal Navy was declared in October 2025.
