General Dynamics in the USA have recently unveiled a new systems called the LWMMG that utilises the .338 Norma Magnum round, positioned between the 7.62mm GPMG and 12.7mm HMG, but based on neither.
The press release says
General Dynamics Armament and Technical Products, a business unit of General Dynamics (NYSE: GD), today unveiled a next-generation Lightweight Medium Machine Gun (LWMMG) at the Joint Armaments Conference in Seattle, Wash.
Identifying an unmet warfighter need, General Dynamics Armament and Technical Products conducted its own research and development program to develop the LWMMG in just over one year. The weapon is designed for low-cost production and for maximum effectiveness at the small unit level, where weight and lethality are decisive factors.
“The LWMMG is an affordable weapon that closes a current operational gap, providing .50 caliber-like firepower in range and effect at the same weight and size of currently fielded 7.62mm machine guns,” said Steve Elgin, vice president and general manager of armament systems for General Dynamics Armament and Technical Products. “Weighing in at 24 pounds and featuring a fully collapsible stock, the LWMMG offers superior mobility and portability in both mounted and dismounted operations.”
General Dynamics’ LWMMG also offers a distinct advantage in both extended and close-in fighting by using the highly efficient .338 Norma Magnum cartridge for increased accuracy and lethality out to 1,700 meters, a distance currently gapped in the operational capabilities of warfighters.
“By employing the larger .338 NM round, the LWMMG delivers twice the range and dramatically increases lethality above the 7.62 round,” said Elgin. “In addition, the LWMMG goes beyond providing suppressive fire and gives warfighters the ability to attack point targets at significantly extended ranges.”
The LWMMG has a firing rate of 500 rounds per minute, a maximum range of 5,642 meters, and is equipped with quick-change barrel technology. In addition to use by dismounted infantry and on ground vehicles, the weapon can be used as the armament system aboard helicopters and littoral craft, providing greater range and effectiveness for those platforms.
“The LWMMG is a well-designed machine gun ideally suited to provide long-range lethality to U.S. and allied forces,” Elgin said.
There are lots of pluses but ammunition weight might be a problem in the dismounted role and the .338NM isn’t used by anything else we have so it would mean yet another ammunition nature being inserted into the logistics chain.
Is this a solution in search of a problem, a game changer, a piece of equipment that can usefully fill a gap or somewhere in between?
