When the service published a semi-formal request for ideas on FedBizOpps last October, it specifically mentioned the intent to move to the higher caliber from the current 5.56 NATO round now in use with the M4 carbine and M249 squad automatic weapon. “It’s very expensive and very hard to change calibers,” he said. “Improving the ammunition is by far an easier way to improve lethality.” https://www.militarytimes.com/news/...cs-will-make-soldiers-marines-a-lot-deadlier/ In 2015, the Small Arms Ammunition Configuration Study showed similar results, pointing to an intermediate caliber as the best option. But the study pushed for higher muzzle energy for extending range and lethality at impact, while maintaining bearable recoil and consistent accuracy. https://www.thedrive.com/the-war-zo...-could-be-the-armys-next-standard-issue-rifle “Our CT weapons and ammunition offer the growth path to a true next-generation small arms weapon for U.S. warfighters, including increased lethality at longer ranges, while also delivering significant weight reductions to the warfighter.” Still, the service’s current leadership is adamant about modernizing and improving the lethality of its forces across the board, moving away from updating existing systems to fielding new ones. https://www.armytimes.com/news/your...ll-fire-a-never-before-seen-ammo-combination/ The 6.8mm round is the offspring of a project formerly known as the Enhanced Rifle Cartridge Program that put together Special Operations Command, the Army Marksmanship Unit and Remington Arms to create an alternative to the 5.56mm round currently in use across the force. That size ammo falls in the sweet spot the Army is looking for, with all the good characteristics of the heavier 7.62mm but with more lethality and accuracy — and coming in at an automatic 10 percent weight savings. https://308ar.com/army-new-6-8-mm-round-becoming-reality/ In development since 2004, Textron Systems’ CT weapons and ammunition offer an innovative weapon design that increases lethality and reduces total system weight by up to 40 percent. Textron Systems has developed rifles, including automatic rifles, in a variety of configurations and calibers, including 5.56mm, 6.5mm, and 7.62mm, and is supporting the Army’s current efforts to revolutionize its small arms capability. Still, the service’s current leadership is adamant about modernizing and improving the lethality of its forces across the board, moving away from updating existing systems to fielding new ones. NGSW is very in line with this general thinking and the Army has an aggressive timetable in mind for fielding both the new infantry rifles and automatic rifles, with a goal of equipping the first unit with the new weapons by 2022.
