#2030

It’s almost 3 in the morning, and I’m lying awake in bed thinking about small arms. I’m trying to put everything out of my mind so I can go to sleep and wake up in the morning, go to the range, and bring you some raw ballistic data. So of course what pops into my head is an almost complete article about just why the Army’s latest whizzbang rifle program is doomed to collapse in a heap. All I have to do is write it.

When the subject is the future of infantry, the conversation inevitably turns to one thing: Powered, armored exoskeletons. Since the publication of Heinlein’s Starship Troopers in 1959, the concept of an armored suit with enhanced mobility from an internal power source has fascinated military futurists, quickly solidifying as a military fiction staple, and even appearing repeatedly in official “future soldier” concepts from armies and companies around the world.

At the 2017 Association of the United States Army annual meeting (AUSA 2017), US Army Research, Development, and Engineering Command (RDECOM) presented a concept for the US Army’s future soldier of the 2030 timeframe, which promised everything from powered exoskeletons, to futuristic optics, to individual network capability. I captured the Command’s two future soldier concept demo videos that were running at the conference, embedded below:

One of the problems of small arms ammunition is that of swept volume. That is, the most ballistically efficient projectiles are the longest and thinnest ones, which cut through the air more easily than squatter, fatter projectiles. Yet, the best projectiles from a propulsion perspective are the widest ones, as they have the most area at their base for the expanding gases to push on, making them more efficient, especially from shorter barrels.
