The Marine Corps is hoping industry can make lightweight .50 caliber ammunition that provides machine-gunners with a 30 percent weight savings over existing linked belts of .50 caliber ammo.
Marine Corps Systems Command recently released a request for information to see if commercial companies have the capability to produce lightweight .50 caliber ammo that "will provide a weight savings when compared to the current M33 .50 cartridge in the DODIC A555 linked configuration," according to the document released on FedBizOpps.gov.
"A belt of 100 Lightweight .50 Caliber cartridges with 101 links shall have a threshold overall weight of 24.6 lbs. or 15 percent weight savings compared to the legacy A555 configuration," the document states. "A belt of 100 lightweight cartridges with 101 links shall have an objective overall weight savings of more than 20.3 lbs. or 30 percent compared to the legacy A555 configuration."
Lightweight ammunition is not a new concept. Commercial companies continue to work new methods to lighten one of the heaviest necessities of warfare.
Ammunition for the M2 .50 caliber machine gun is prepared as Marines with Headquarters Battery, 3rd Battalion, 12th Marine Regiment, 3rd Marine Division, III Marine Expeditionary Force, prepare for their first day of firing crew-served weapons at the East Fuji artillery range.
The Chesapeake Cartridge Corporation showed off its new line of nickel ammunition at SHOT Show 2018 in Las Vegas.
The shell casings, made of aluminum-plated nickel alloy, are lighter and stronger that traditional brass casings, Ed Collins, Chesapeake's director for business development, told Military.com in January 2018.
The company is working toward creating ammunition that's 50 percent lighter than conventional brass ammo. Currently, the company makes military calibers such as 9mm, 5.56mm and 7.62mm NATO, but it plans to make it in additional calibers in the future.
Companies such as PCP Ammunition make polymer-cased ammunition, which offers up to a 30 percent weight savings compared to brass-cased ammo.
Textron Systems makes case-telescoped weapons and ammunition. The ammo concept relies on plastic case rather than a brass one to hold the propellant and the projectile, like a conventional shotgun shell.
Over the past decade, the U.S. Army has invested heavily in Textron's concept, formerly known as Light Weight Small Arms Technology.
Textron doesn't currently make .50-caliber, case-telescoped ammunition, but its 5.56mm CT ammo weighs about 37 percent less than standard belted 5.56mm.
Companies have until June 1, 2018, to respond to the RFI, the document states.
