Royal Navy successfully tested its new Martlet anti-ship missile against a target boat in the Irish Sea, the service announced.
The Navy’s Type 23 frigate, HMS Sutherland (F81) fired four Martlet missiles at a fast-moving speedboat off the Welsh coast to see whether the weapon could be launched from a ship as well as a helicopter.
Martlet is the Royal Navy designation for Thales’ Lightweight Multi-role Missile (LMM).
The Royal Navy warships are currently armed with a series of machine-guns and Mini-guns (manually-operated Gatling guns) to fend off small craft, while some are also equipped with Phalanx close-in weapon system (CIWS) which spew out a hail of bullets at incoming aircraft, missiles and threats on the surface. The Navy wanted to add to those defences and turned to the new missile system, modifying it so a launcher could be fitted to the existing 30mm automatic gun.
Just five months after the idea was mooted, the Plymouth-based frigate was off the Aberporth Range at the southern end of Cardigan Bay facing a fast inshore attack craft tearing across the water. After first proving that the gun could still fire accurately with the missile fitted – 120 rounds obliterated a large red ‘killer tomato’ target – and that the sensors behind Martlet could track its radio-controlled foe at ranges of up to five kilometres.
Finally, four missiles were fired – one to test the effect of the Martlet ‘blasting off’ from its launcher on the gun mounting and the side of Sutherland (the missile accelerates to one and a half times the speed of sound in an instant), three packed with telemetry to measure the missile’s accuracy (ordinarily the weapon carries a 3kg warhead).
All was recorded by high resolution cameras so the team from manufacturers Thales and military scientists could analyse the effects in minute detail.
“The current defence against fast inshore attack craft, the 30mm gun, is highly effective for closer range engagements,” said Lieutenant Commander George Blakeman, HMS Sutherland’s Weapon Engineer Officer. “By adding the missile to the gun mount it is anticipated it will extend the reach of the ship’s defensive systems – key to successful defence against fast craft using swarm attack tactics. The Fighting Clan has always had a reputation for being at the forefront of innovation and we were delighted to be chosen to support this trial.”
The frigate’s Commanding Officer Commander Tom Weaver added: “The impressive result of this trial was achieved through the hard work and cooperation of a wide array of industry and defence partners and it was rewarding for Sutherland to have played such a key role in its success.”
Malcolm McKenzie from the missile’s manufacturer Thales said: “The rapid integration of Lightweight Multi-Role Missile on to the 30mm gun demonstrates how Thales can quickly develop cost-effective high capability solutions to meet the evolving threats faced by our naval forces. The success of the trial was a true team effort and delivery was only possible due to the outstanding contributions of HMS Sutherland crew.”
LMM was originally conceived as Thales’ response to the UK MoD’s Future Air-to-Surface Guided Weapon (Light) , or FASGW(L), requirement. The missile was to be fired by AW159 Wildcat helicopters to take out small boats which posed a threat to the Fleet, alongside the heavier Sea Venom for dealing with larger warships. Sea Venom was developed by MBDA for MoD’s Future Anti-Surface Guided Weapon (Heavy), or FASGW(H) requirement. French Navy also operates this missile and is called as Anti-Navire Léger (ANL) in its service.
The LMM missile was recently launched against Banshee drones from shoulder-launcher during testing by Royal Marines at the Air Defence Range Manorbier in southwest Wales, and also against small boat target from land-based launcher as part of the Integration testing phase conducted by Thales at at Royal Artillery Air Defence Range at Manorbier.
