New Army ammo facility to supply millions of 6.8 mm rounds annually

The Army is one step closer to producing millions of rounds each year of its newest caliber for the service’s newest rifle and light machine gun combination — the Next Generation Squad Weapon.

The service’s Joint Program Executive Office for Armaments and Ammunition broke ground Feb. 5 on a 6.8 mm ammunition production facility at Lake City Army Ammunition Plant in Independence, Missouri, according to an Army release.

Current plans show the facility being completed by 2026 and fully operational by 2028, officials said.

The move aims to give the service its own production line for the 6.8 mm cartridge, which is the caliber the Next Generation Squad Weapon is chambered for, both in its rifle and automatic rifle configuration.

The XM5 and XM250, respectively, are replacing their counterparts, the M4 carbine and M249 Squad Automatic Weapon, among the close combat forces. Both are chambered in the legacy 5.56 mm cartridge.

The Army is leading the project, while the Marine Corps and Special Operations Command have been closely involved in the development of the weapon and round in recent years.

Lake City has been a major source of small arms ammunition for the Army and other services for decades. Historically, the plant has produced 5.56 mm, 7.62 mm, .50 Browning Machine Gun, and 20 mm ammunition.

During the height of the post-9/11 wars, from 2007 to 2018, the plant produced nearly 1.4 billion rounds, according to Northrop Grumman.

“It is not lost on me that victory on the battlefield begins in our production facilities,” Maj. Gen. John T. Reim, program executive officer for armaments and ammunition, said in a statement. “Lake City has been central to our nation’s ammunition production since 1941, and this new facility builds on that proud and historic legacy.”

The 6.8 mm round delivers the distance and energy on target of the larger 7.62 mm round but at a lighter weight and with better accuracy, according to Army officials.

Currently, rounds for the Next Generation Squad Weapon are being produced by Sig Sauer, manufacturer of both the rifle and automatic rifle variants.

Ammunition manufacturer Olin Winchester will operate the new plant. The facility will span 450,000 square feet at the Missouri site, according to the Army.

The operation will include manufacturing systems for cartridge cases and projectiles, quality controls, packaging and testing laboratories. According to the release, industries in the Kansas City, Missouri, region will support an estimated 90% of the work.

When the facility hits operational status, it is expected to produce 385 million cases, 490 million projectiles and 385 million loading and packaging operations rounds each year.

There are about a dozen units in the fielding pipeline for the Next Generation Squad Weapon in fiscal 2025. They include:

• From October to December, the Army Reserve’s 100th Infantry Battalion, 442nd Infantry Regiment at Fort Shafter, Hawaii; elements of the 25th Infantry Division, at Schofield Barracks, Hawaii; the Army’s Ordnance School, at Fort Gregg-Adams, Virginia.
• From January to March, the 3rd Brigade, 101st Airborne Division at Fort Campbell, Kentucky; 2nd Battalion, 75th Ranger Regiment at Joint Base Lewis-McChord, Washington; 1st Brigade, 1st Armored Division, at Fort Bliss, Texas.
• From April to June, the 1st Battalion, 75th Ranger Regiment at Hunter Army Airfield, Savannah, Georgia.
• From July to September, the 1st Brigade, 34th Infantry Division with the Minnesota Army National Guard; multiple 10th Mountain Division battalions.

Last October, the 1st Battalion, 506th Infantry Regiment, 101st Airborne Division was one of the units to conduct live-fire testing of the weapon. The “Red Curahee” soldiers ran tactical patrols after having run shooting ranges at limited visibility, according to the Army.

The squad-sized elements put the weapon through its paces on terrain at their home station of Fort Campbell, Kentucky. At the time, Maj. Craig Hymel, the battalion executive officer, explained the culminating event.

“The squad live [fire] will be the last event in conjunction with the stress shoot that participants execute,” Hymel said. “At which point, the Operational Assessment Team is going to collect and finalize all the data.”
