Lightweight Multirole Missile

The Lightweight Multirole Missile (LMM) is a lightweight air-to-surface, air-to-air, surface-to-air, and surface-to-surface missile developed by Thales Air Defence for the United Kingdom. In Royal Navy service, the LMM is referred to as Martlet, a mythical bird from English heraldry that never roosts. The LMM was developed from the Starburst surface-to-air missile to meet the UK's Future Air-to-Surface Guided Weapon (Light) requirement (supplemented by the heavier Future Anti-Surface Guided Weapon (Heavy) missile now known as Sea Venom) to provide Royal Navy AW159 Wildcat helicopters with the ability to engage smaller and manoeuvrable naval craft. A glide variant of the LMM known as FreeFall LMM (FFLMM) (or Fury for the U.S. market) is designed as a lighter munition to equip drones and is currently slated to equip the British Army's Dispensing Rocket Payload for the GMLRS-ER and Precision Strike Missile (PrSM). The Ministry of Defence (MoD) placed an initial order for 1,000 missiles with deliveries due to start in 2013. However, initial operating capability was considerably delayed and took place in 2021 with full operating capability achieved in 2025. In March 2026, the MoD said that in order to protect the UK's partners in the Gulf region, it would order more missiles, as well as provide them with training in the UK.
