#Future

The golden age of polymer cased ammunition has probably already begun. Certainly, Norwegian-Finnish ammunition manufacturer Nammo seems to believe that, as they recently took a significant stake in American company MAC, LLC, makers of polymer-cased composite ammunition, some of which has already been type-classified by the United States Navy. MAC, LLC will continue as an independent company.  Nammo announced the acquisition via a press release, which is embedded below:

At an AUSA breakfast conference yesterday, US Army Chief of Staff General Mark Milley gave us a hint at exactly what the US Army’s next rifle could look like, and the focus was on extended range capability. The rifle, Milley said, will give a 10x improvement in capability through the type of ammunition, optics, and degree of chamber pressure specific to it, with the aim of providing the soldier a weapon with much more accuracy and range than the current M4 Carbine. Milley also clarified that the term “10x” was not intended to be a precise measurement of the capability growth, but rather a term indicating significant improvement. The new rifle will come as part of an effort that also includes new artillery, tanks, aircraft, and virtual reality training facilities, Milley said.

The Commandant of the United States Marine Corps (CMC) has stated his approval for an overhaul of the front-line infantry Marine’s gear – including the fielding of the Heckler & Koch M27 Infantry Automatic Rifle as a standard issue rifle, to replace the M4 Carbine. The move comes after considerable debate as to what the USMC’s next infantry weapon configuration should look like. From Military.com’s KitUp!:

Canton Ohio custom gunmaker Middlebranch Machine has released a teaser image of a new kind of suppressor, which they say is made of “carbon fiber composite” construction. Unlike previous efforts at making carbon fiber suppressors, Middlebranch Machine’s design does not seem to use a straight carbon-fiber tubing body, but appears to be 3D printed, instead. This is strongly suggested by the background of the image which shows a customized Glock with a unique looking suppressor in front of what is probably a Markforged Mark Two carbon fiber 3D printer. Mark Twos are some of the only carbon fiber 3D printing machines in the world.

Recently on The Firearm Blog we talked about one of the great might-have-beens, the German caseless G11 rifle developed by Heckler & Koch during the 1970s and 1980s. Today we have a video from 1990 filmed at Aberdeen Proving Grounds of a demonstration of the G11K2 on the firing range.

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.

Is the US Army pushing for a new high-powered 6.Xmm caliber with their new NGSAR program? Recently, the listing for the NGSAR industry day in December was updated with a document describing in part the agenda of the second conference. Scheduled for 9:45 in the morning in the document is a 15 minute long presentation on “Ammunition Data – Surrogate Projectile and Specs”, presented by Todd Townsend, David Charowsky, and Mark Minisi. Minisi’s name may not be well-known, but it will be familiar to astute students of recent wound ballistics literature: It was Minisi who developed the finite element analysis-based tissue damage model, which has been refined over the past decade at ARDEC through PM Maneuver Ammunition Systems (PM-MAS). Mr. Townsend is also likely representing PM-MAS, now under the leadership of Colonel Hector Gonzalez. 

In the comments section of my recent Brief Thoughts article regarding caseless ammunition, there was a discussion about whether the cookoff issues of caseless would also be problem for LSAT-style polymer cased telescoped ammunition. Based on conversations I have had with subject matter experts regarding polymer cased ammunition in general, I noted that a lower cookoff threshold is one of the challenges I would expect CT ammunition developers to face. However, after some back-and-forth in the comments, I decided to contact LSAT/CTSAS program officer Kori Phillips regarding this issue (as it was not something I covered in my three-part interview with her), and she kindly agreed to allow her comments on the matter to be published here on TFB. They are below:

A warning against romanticism in military planning.

In the world of “might-have-been” small arms, a world of .276 Garands and NATO-standard EM-2s, none flew so high nor fell so far as the Heckler & Koch G11 caseless hyperburst assault rifle. Designed to out-match any contemporary small arm in a Cold War shootout across Central Europe, the G11 combined the aesthetics of a scifi plasma rifle with complexity of a Swiss watch. The result was a bullpup caseless wunderwaffe with a 2,000 round per minute hyperburst setting, and a price tag that, as the joke goes, compared unfavorably with reconstructing East Germany.

Texas company True Velocity, LLC, has released the first images of their advanced lightweight polymer composite cased ammunition design via Instagram. Training company BAT Defense sent out an image of what appear to be 12.7×108, .50 BMG, and 5.56mm rounds made by True Velocity, saying that the ammunition was originally developed to reduce the weight of ammunition carried by light helicopters (such as Littlebirds).

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.

Caseless: The ammunition designer’s holy grail, and the engineer’s worst nightmare. It would obsolete the cartridge case overnight, resulting in cheaper, lighter, and more compact ammunition. Weapons would be able to carry 50, 60, or more rounds in slim, inexpensive magazines, and expel them at a rate of fire much higher than current weapons are capable of – not only because the ammunition is lighter and therefore more could be carried to feed such thirsty guns, but because the extraction and ejection cycles of the weapons themselves could be eliminated.

With Level IV armor rising in availability, calls for “overmatch”, and the increased presence of urban warfare, will designers be able to meet the requirements for future small arms? Forumgoer Poliorcetes raised this question in a discussion at the Military Guns & Ammunition forum:

If we can make a round that is significantly better than the existing 5.56mm or 7.62mm ammunition, shouldn’t the military just bite the bullet and switch, to the benefit of the servicemen and women in harm’s way? What’s stopping the powers that be from making the incremental improvements that everyone knows are possible?
