SOCOM wants a new armor piercing sniper bullet. Here’s one option engineers are developing
As the U.S. military shifts its focus back to fighting more traditional, near-peer adversaries like Russian or Chinese troops, the services are building out plans to revamp their gear to deal with better-equipped forces backed by money and technology from world powers.
That extends all the way down to the clothing and equipment each of these adversaries could be wearing into battle, including sophisticated body armor.
That's why SOCOM is reportedly looking at replacing its decades-old armor piercing small arms round.
“Snipers in USSOCOM units have a capability gap in their ability to penetrate enemy body armor, small boat engines and concrete barriers,” Crane researchers said in a slide presentation at this year's National Defense Industries Association Armaments Symposium.
The current round uses a discarding sabot the shields a sharpened tungsten penetrator that'll beat most armor and hard targets.
But that round is expensive at more than $10 per cartridge, can damage modern small arms accessories like suppressors and muzzle brakes and doesn't hold zero when switching from a traditional jacketed round to the AP round. That makes it difficult for snipers to go from one round to another and hit their target in the heat of battle.
So researchers at the Naval Surface Warfare Center in Crane, Indiana, are looking at a new way to make the rounds cheaper, easier on snipers' guns and more ballistically consistent with common, jacketed bullets.
Dubbed “aeroshell” projectiles, the Crane engineers want to build and test bullets with a tungsten penetrator jacketed in a polymer shell. Federal Ammunition, a civilian ammo company, makes rounds with similar characteristics dubbed “Syntech."
These rounds are typically used by competitive shooters who shoot many rounds in practice and at matches and want to preserve barrel life and diminish spawl from hitting steel targets.
Crane researchers want to take the same thought process and apply it to a new AP round. The actual penetrator could have a slightly different shape than the current rounds, with more of a traditional bullet profile than today's needle-like AP round penetrator.
Researchers plan to create about 150 rounds of this new aeroshell AP round in .338 Norma Mag, 300 Norma Mag and 6.5 Creedmoor. They plan to test the rounds against representative body armor at 100, 400, 800 and 1,000 meters.

An Air Force radio that can run for a week in the sun
By: Adam Stone The Pentagon has long been looking for a way out from under its tradition of massive, multi-year, multi-billion-dollar projects. With the rapid pace of technological development, military leaders have sought tools and strategies for more rapid acquisitions. There's the Defense Innovation Unit, or DIUx, a Defense effort to make faster use of emerging technologies. Some organizations have also turned to contractual tools such as the OTA, or other transaction authority, as a means to accelerate the technology buying process. Recently, technicians at McConnell Air Force Base proved that homegrown ingenuity can make a difference, too. Workers there used a local partnership and a modest development effort to craft a portable, solar-powered communications system. “The military needs to be ready to go anywhere and solar enables that,” said Tech. Sgt. Clayton Allen of the 22nd Air Refueling Wing. As a non-commissioned officer in charge of the wing's XPX innovation team, Allen led the effort to shrink down the standard communications package and make it self-sustaining. The three-man team got the job done in about 400 hours, working in cooperation with Wichita State University's GoCreate rapid-innovation lab. “We took it from a box the size of a small room and made it something you can drag behind you like luggage, weighing about 150 pounds,” he said. An expeditionary force typically might have to spend a couple of days setting up its communications operation. The newly-developed unit works right out of the box and costs about $12,000 less, the team said. As a solar-power unit, it also does not rely on the presence of a generator, making it easier to deploy in a wider range of circumstances. “It is completely self-sustainable, powered by solar power, and the solar panel can extend the [battery life] out almost indefinitely,” Senior Airman Aaron Walls, an XPX innovation team member, said in an Air Force news release.
