Norway: Military Alliances
The question
To ask the Secretary of State for Defence, under the Lunna House Agreement, by when will the Royal Navy adopt advanced Norwegian naval strike missiles and what existing capability will they replace.
Answered by Luke Pollard
The Naval Strike Missile (NSM) is a Norwegian anti-ship and land attack missile, which has been acquired for the Royal Navy’s escort force. It replaces the Harpoon anti-ship missile, which went out of service in December 2023. The NSM is 20 years newer, has greater range, and is far more capable than the system it replaces.
The Royal Navy completed its first successful launch of an NSM missile from HMS SOMERSET in Norway in September 2025 at Exercise AEGIR. Test firings are now complete and the NSM is expected to enter service later this year.
