Martlet (missile)
Martlet or 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. It is named after a mythical bird from English heraldry that never roosts, the Martlet.
The LMM was developed from the Starburst surface-to-air missile to meet the UK's "Future Air-to-Surface Guided Weapon (Light)" requirement to equip the Royal Navy's AW159 Wildcat helicopters and supplement the heavier Sea Venom missile by the engagement of smaller and manoeuvrable naval craft.
A glide variant of the LMM known as FreeFall LMM (FFLMM) or Fury 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.
The Lightweight Multirole Missile was initially conceived as Thales' response to the MoD's FASGW(L) or Future Air-to-Surface Guided Weapon (Light) requirement. FASGW consisted of both a heavy and light system. The heavy requirement would become the Anglo-French developed Sea Venom designed to replace the Sea Skua as a helicopter launched anti-ship weapon for use against fast-attack-craft, landing craft and larger vessels such as Corvettes. The light requirement was to be a new weapon optimised around defeating fast-in-shore-attack-craft particularly in response to the force structure of the Iranian Navy.
Thales submitted a re-designed Starburst missile (the predecessor to Starstreak) which would maintain the use of a laser beam-riding guidance system as means of overcoming the tight rules of engagement present in in-shore waters and ensuring continued effectiveness against low-reflectivity targets. It was designed to be launched from a variety of naval, air and land platforms against a wide range of targets.
Qualification testing and initial production commenced in late 2011, following an initial contract by the UK Ministry of Defence in April 2011. Thales has conducted successful guidance control firings, including a semi-active laser (SAL) version. The MoD contract was for the design, development, and commissioning of a laser beam rider version of LMM, together with production of an initial quantity of 1,000 missiles.
The LMM weighs approximately 13 kilograms (29 lb) with a length of 1.3 metres (4 ft 3 in) and a diameter of 76 millimetres (3.0 in). The weapon is guided using a laser beam-riding system but Thales have proposed a variety of additional seekers including a semi-active laser, terminal Infrared, and GPS/INS systems.
