US Army Returns to Hand-Held Grenade Launchers

Barrett Firearms, in conjunction with MARS, Inc., recently unveiled a full-size mockup of the company's .30mm self-loading grenade launcher at an Association of the US Army (AUSA) event. The system is currently known as the Squad Support Rifle System (SSRS).


The Barrett Firearms grenade launcher mockup is equipped with the XM157 smart optical system from Vortex Optics, which is supposed to be installed on the new 6,8 x 51 mm assault rifles and machine guns of the US Army. A logical attempt to unify sighting systems.

Earlier, FN America (the American subsidiary of the same Belgian Fabrique Nationale) demonstrated its model of a grenade launcher under the index PGS-001. Both companies became finalists in a promising competition announced by the US Army and called the "xTech Soldier Lethality challenge". The technical task involves the creation of a self-loading grenade launcher, carried by one person and capable of hitting manpower and equipment, including lightly armored, at distances of at least 500 meters.



And army leaders generally do not hide the fact that the current competition is a continuation of the ideas embedded in the experimental XM25 CDTE (Counter Defilade Target Engagement) grenade launcher.


The entire line of ammunition proposed for production and some characteristics of the Squad Support Rifle System (SSRS) from Barrett Firearms on the stand during the presentation. The weight of the system is suggested to be more than reasonable – 6,3 kg. However, this is the weight of an unloaded grenade launcher with optics.

We recently wrote about the XM29 rifle and grenade launcher system, which was part of the Objective Individual Combat Weapon program. The concept of an automatic grenade launcher with an underbarrel machine gun turned out to be a failure, as did other elements of the OICW program. The complete rearmament of the American army did not take place. But the military decided to develop the idea of ​​a self-loading grenade launcher with programmable ammunition. They took the idea of ​​a grenade launcher and sighting system from the XM29, increased the caliber to 25 mm, as was supposed for the OCSW (Objective Crew Served Weapon) grenade launcher, and eventually got the XM25.


General view of the PGS-001 grenade launcher model from FN America.

Unlike many previous US Army R&D efforts, the XM2000 work that began in the 25s looked very promising. Not only did the system fire and hit targets, it was also quite reliable. During the entire testing and operation period, there was only one accident caused by a malfunction in the grenade launcher's automatics (double feed), and the shooter was injured. Quite a good result for a fundamentally new weapon. weapons with a fundamentally new ammunition.

The crowning achievement of the XM25's career was military testing, and not just anywhere, but in units stationed in Afghanistan. It is often claimed that the system ended up in American special forces units, but according to open source data, almost all XM25s were transferred to the 101st Airborne Division.

And it seems like the infantry "on the ground" were also doing well with the grenade launcher... But the program died in 2018, and the XM25 never went into production. So why?

The most important thing is the price. The complex turned out to be very expensive. If the Objective Individual Combat Weapon program was supposed to retire a bunch of weapon systems and ultimately save money on this, then the XM25 became an addition to the existing small arms and grenade launcher system. Accordingly, the order had to be large, but not designed to rearm all army units - 10 samples. Apparently, the army contractor was unable to ensure an acceptable cost per unit with such a number of ordered grenade launchers. The complex and the new ammunition also became an additional burden on the logistics system.

Well, there were also two less serious factors. The first was weight. The system itself weighed a reasonable 6 kilograms, but with a full set of ammunition, the weight was approaching 20. And this led to the second problem: a soldier with a grenade launcher was armed only with a grenade launcher and a pistol. He could no longer carry an assault rifle or even a personal self-defense weapon. That is, in essence, there was a rollback to the times of the beginning of the American intervention in Vietnam, when a soldier with an M79 grenade launcher carried only a pistol in addition to it and, having used up all the ammunition for the grenade launcher, turned from a combat unit into a burden for the unit.

There is very little information about the new grenade launcher system. But, judging by the samples that were presented, it can be assumed that some of the problems that were inherent in the XM25 were decided to be eliminated. And the first is the cost. On both demonstration mock-ups-concepts, the sights are simply mounted on a Picatinny rail. That is, most likely, there will be no complex integrated system for automatically setting the range of the air detonation of ammunition. Plus, the system is supposed to be as universal as possible. Its tasks will include fighting small UAVs and knocking out door locks, that is, functions that are currently assigned to shotguns in the army. A large futuristic grenade launcher-shotgun.


Infographics showing the range of ammunition for the XM25 grenade launcher. Aside from the training and programmable high-explosive airburst rounds, the other 25mm rounds remain promising. According to Barrett Firearms, their grenade launcher will immediately be equipped with an even larger range of ammunition than was once expected for the XM25.

It is also known that American Rheinmetall Munitions, Knight Technical Solutions and Plumb Precision Products are participating in the competition, so perhaps these are not the last concepts demonstrated on this grenade launcher theme.

Regardless, it will be interesting to see where the Army's dreams of a self-loading grenade launcher, which looks more like a sci-fi "bolter" from the Warhammer 40000 fantasy universe than a real weapon, take it. But the Army is currently fielding several new small arms, so perhaps a handheld automatic grenade launcher could be a good addition to the Army's new weapons system.

    Eh... A cool topic, too bad it didn't take off... Indeed, after the ammunition is used up, all that's left is to pick your nose or go to the FPV bakery...

    The ammunition carrier is appointed from among the squad soldiers. to provide him with ammunition and everything necessary for firing in a timely manner. He must be able to quickly and deftly load magazines with cartridges and prepare hand grenades for combat use.

    He is obliged:

    - be in the squad position and fire at the enemy;

    - know the location of the company (platoon) combat supply point and a hidden route to it;

    - upon receiving the command from the squad commander, go to the combat supply point, receive and deliver ammunition to the squad position by the established deadline, report to the squad commander and, if necessary, distribute it to the position.

    Well, then why, for the life of me, a self-loading one? That is, it is necessary to somehow increase the rate of fire relative to the underbarrel grenade launcher or something? But this will result in weight, dimensions, and the need for a feed mechanism and a magazine (and the task of ensuring the reliability of all this, especially with different BC), and the price. IMHO here either single-shot break-action in the spirit of the M79, or a sliding pump mechanism for 2-4 shots. This is the maximum that can be mastered when shooting off-hand. It will also make it easy to control / change / reload shells for different purposes, remove restrictions on changing the energy of charges (critical for the operation of automation). But have you tried to simply install fancy optics on the M79?

      Do you need to increase the rate of fire relative to the underbarrel grenade launcher or something?

      Yes. Obviously. High density of fire. Especially since it is not a problem. They decided to exchange a couple of kilos of additional weight for the ability to fire a series of shots, which is very significant for fragmentation grenades.
      the need for a feed mechanism and a magazine

      What's there? A regular magazine and bolt, only the weight is big. A lot of mounted grenade launchers shoot normally, and feed from a belt, and there's no need to talk about magazine-fed automatic guns.
      or a sliding pump mechanism for 2-4 shots

      Which can easily be turned into a semiautomatic if you add a movable barrel. Which is actually what the domestic GM-94 is.
      This is the maximum that can be achieved when shooting off-hand.

      Again GM-94, MGL, RG-06 and QLB-06.
      This will also make it easy to control/change/reload projectiles of different purposes, and will remove restrictions on changing the energy of charges (critical for the operation of automation)

      The main thing is to have enough energy to recharge, and this is very easy to do.

    What's the problem?

    The complex itself weighed a quite reasonable 6 kilograms, but with a full set of ammunition the weight was already approaching 20.

    What, they couldn't calculate the weight of the ammunition before they started developing it? They spent a ton of money and then, oh, suddenly...

    And indeed, as indicated above, what is the problem with assigning a second number to carry additional ammunition, and/or giving each soldier in the squad an extra magazine.
    It seems that they couldn’t simply cut up the budget.

      The second number in the department where everyone is armed with grenade launchers?
      Ours are better - a loaded GM weighing 6 kg and a cartridge belt for 12 shots weighing 4 kg. And these are thermal bars... It's heavy but bearable.

        Why arm everyone with these? Specifically, one or two shooters in a squad, and each fighter has an extra pair of magazines (about 7 kg). When fighting in the city, it should be almost imbalanced.

        By the way, about the GM-94 - I asked at the exhibition why the caliber was so non-standard, it turns out to be an additional nomenclature. They answered that the VOG-25 has a risk of impalement in the pump drive, and the VOG-17 gives too much recoil, the mechanisms quickly fail, so they had to create their own ammunition from scratch.

          I served in the NBC protection, if you understand what I mean... All the fighters in the platoon had GM-94. And as for the caliber - there is a plastic grenade VGM-93, developed for special forces, you can stuff anything into such a case. You can look at the nomenclature of VGM-93. Although in fact there are only inert and thermobars.

              And don't. Believe me, a thermal bar in the chest, in the armor, it's scary even from the outside.
