Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the in-service date is for the Royal Navy’s Future Anti-Surface Guided Weapon.

The Future Anti-Surface Guided Weapon (FASGW) requirements will be fulfilled by a “light” and “heavy” capability.

FASGW (Light), also known as Martlet, achieved Initial Operating Capability in October 2021 and has been in operational service with the Royal Navy since then. The programme is progressing towards Full Operating Capability and achievement of this milestone is forecast for December 2025.

FASGW (Heavy), also known as Sea Venom, reached Initial Operating Capability in May 2025 in time to be deployed on Operation HIGHMAST. Full Operating Capability is on-track to be delivered by 2029.
