Did you know that the Swiss Armed Forces do not take part in any armed conflicts in other countries? The primary role of the Swiss Armed Forces is Homeland Defence only. However, they have been part of several peacekeeping missions around the World, for instance in Bosnia and Herzegovina.

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.

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:

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.

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.

Previously, we discussed trying to lighten the soldier’s load by making the cartridge case out of different materials, including aluminum and compositing the case out of polymer and metal. Yet, wouldn’t the lightest possible case configuration be… Having no case at all? That’s the thinking behind one of the most ambitious ammunition configurations there is, the case-less round.
