Is that possible?
The Army claims its new assault rifle will unleash a hailstorm of specially-designed shells with as much chamber pressure as a battle tank to tear through even the most advanced body armor — and if all goes according to plan, the soldiers will get them to play with sooner than they thought.
The service plans on fielding a Next Generation Squad Automatic Rifle (NGSAR) — the first version in the Army’s Next-Generation Weapons System that chambers a round between 6.5mm and 6.8mm — as a potential replacement for its 80,000 M249 SAWs starting in fiscal 2022 rather than the original target date of fiscal 2025, Col. Geoffrey A. Norman, force development division chief at Army HQ, told Task & Purpose, with two per nine-man infantry squad.
While the service still hasn’t set official requirements for the system, the NGSAR will weigh less, shoot farther, and pack more punch than the service’s existing infantry weapons, Norman told Task & Purpose. And more importantly, the platform will incorporate a chamber pressure superior to the current system in soldiers’ arsenals to ensure that the rounds can still blast through enhanced enemy body armor at up to 600 meters.
The goal, as Norman put it, is to equip infantry soldiers with an automatic rifle “that fires a small bullet at the pressure equivalent to what a tank would fire.”
“The chamber pressure for the standard assault rifle is around 45 KSI [kilopound per square inch], but we’re looking for between 60 and 80 KSI … the chamber pressure when an M1 Abrams tank fires is on that order,” Gordon told Task & Purpose. “We’re looking to reach out around 600 meters and have lethal effects even if the target is protected by body armor.”
The NGSW program currently consists of the NGSAR, a Next Generation Squad Carbine (NGSC), and a squad designated marksman rifle, along with specialized ammunition and fire control system. But while the Army had previously focused on fielding an improved carbine with a range and accuracy superior to the standard M4 that would also chamber a round between 6.5mm and 6.8mm, the service recently changed gears to prioritize the muscular automatic NGSAR.
