Army Not Interested in Marine M27; Will Pursue Next-Gen Auto Rifle

Military.com |7 Feb 2018 |By Matthew Cox


U.S. Army modernization officials on Wednesday briefed lawmakers on the service's plan to equip soldiers with futuristic small arms that will ultimately replace the M4 carbine and the M249 squad automatic weapon.

Lt. Gen. John Murray, deputy chief of staff for Army G8, testified with other Army modernization generals before the Senate Armed Services Committee's Airland subcommittee on the future of Army modernization.


Subcommittee chairman Sen. Tom Cotton, R-Arkansas, wanted to know what the Army is doing about enemy body armor that the current 5.56mm round is unable to penetrate.

"There has been a proliferation of body armor, specifically Russian and Chinese, designed to defeat traditional 5.56mm NATO ammunition which is of course what our soldiers fire from their M4s," Cotton said. "What are we doing to address what is a very serious issue for the soldier on the front lines?"

Last May, Gen. Mark Milley testified to the Senate Armed Services Committee that the service's current M855A1 Enhanced Performance Round will not defeat enemy body armor plates similar to the U.S. military-issue rifle plates such as the Enhanced Small Arms Protective Insert, or ESAPI.

The revelation launched an ad-hoc effort to acquire new 7.62mm Interim Service Combat Rifle, mainly for infantry units, but the idea quickly lost momentum.

Now the service has a two-phased approach, which starts with acquiring a standardized 7.62mm Squad Designated Marksmanship Rifle, Murray said.

"That gives us the ability to penetrate the most advanced body armor in the world," he said. "We are accelerating the Squad Designated Marksman Rifle to 2018; we will start fielding that in 2018."

The Army had hoped to start fielding the advanced 7.62mm armor-piercing round in 2018 as well, but that effort will take another year to complete, Murray said.

The SDMR "will still penetrate that body armor, but you can't get that extended range that is possible with the next generation round," Murray said.

Phase two of the effort will be the development of the Next Generation Squad Weapon.

"The first iteration will probably be an automatic rifle to replace the M249 squad automatic weapon, which is also a 5.56mm," Murray said.

The Army has decided, however, that it isn't interested in following the Marine Corps' adoption of the M27 Infantry Automatic Rifle.

"We have been pushed on the M27, which the Marine Corps has adopted, that is also a 5.56mm which doesn't penetrate, so we are going to go down a path next generation squad weapon automatic rifle first to be closely followed, I'm hopeful, with either a rifle or a carbine that will fire something other than a 5.56mm.

"That is what we see as a replacement for the M4 in the future."

Murray added that "It probably won't be a 7.62mm; it will probably be something in between -- case-telescoping round, probably polymer cased to reduce the weight of it.

Murray also confirmed that the Army already has a science and technology demonstration weapon, made by Textron System.

The working prototype has evolved out Textron's light and medium machine guns that fire 5.56mm and 7.62mm case-telescoped ammunition developed under the Lightweight Small Arms Technology program.

Over the last decade, the Army has invested millions in the development of the program, which has now been rebranded to Textron's Case-Telescoped Weapons and Ammunition.

"It's too big; it's too heavy," Murray said. "We have recently opened it up to commercial industry for them to come in with their ideas. We have offered them some money to come in a prototype it for us that type of weapon."

Murray said that such as weapon "can achieve weights similar to the M4's 5.56mm ammo -- the weapon will probably weigh a little bit more, the ammo will weigh a little bit less and we can get penetration on the most advanced body armor in the world well out beyond even the max effective range of the current M4."

The Army had planned on fielding a the new Next Generation Squad Weapon by 2025-2026, but the service has now accelerated the effort to have some kind of initial capability by 2022 or 2023 at the latest, Army officials maintain.

Makes sense for the army to go that route, they have far more people than the marines. If the army is going to spend the money to upgrade the weapons they want a leap forward not a stutter step, the AR in 5.56mm is an old weapon in terms of military firearms so it makes sense to push for something more modern and effective.

The chances of a war between the US and any power able to field body armour en mass is so slim that the army can take a bit of time to sort a replacement. As nice as the M27 likely is, the M4 is still quite effective at putting the enemy in the ground, or at least keeping their heads down while arty and air power put them in the ground.
 
Neat. I'm thinking a 6.5mm projectile in a case that has a capacity around that of the .308, hmmm. What fits that bill? Hint: It rhymes with boo-bixty.

Polymer cases, again, neat. In the future maybe I won't have to search high and low for oddball cartridges, I'll just fire up the 3d printer and print off another 50 of them. :)
 
Why not just develop the 7mm-08? Oh yeah, because we have to reinvent the wheel in order to make someone a nice pile of tax dollars.

The same reason 7.62x51 was dropped from standard issue, all that brass and powder is heavy and bulky. Weapons aren't cheap, not developing and improving your weapons so that you can win the next fight is even more expensive.
 
If I read the article correctly the issue is with the amount of knockdown and penetration with pretty much any 5.56 round, and the 7.62 is just too bulky and heavy.

They might be better served by staying with 7.62 X 51 or a round based on that and working on better resupply to carry that heavy, bulky ammo. Boston dynamics had developed robots that could carry ammo to the soldier. Noisy as all getout but work on that and drone delivery.

That, and get away from the firehose doctrine where you go through 600 rounds in a day.
 
You should never go full fire hose!!!

I’m still waiting for the day we fire mini guided rockets from our guns.

Let’s also not forget many countries are supplied by Russia and China that employe their body armour. And or flat out use steel plates to do the job. I’m willing to bet they run into body armour more often than people would like to think.
 
Military industrial complex doing its thing to keep those defense budgets rolling.

As far as practical military applications:

Fact: shot placement trumps caliber every time.
Fact: there are other reasons to expend ammunition which don't necessarily involve shooting to kill.
Conclusion: carry as much of the lightest ammunition you can find.

That said, 5.56 should be around for another 50 years or so until they release reliable caseless munitions or phased plasma rifles in the 30 watt range.

The textron plastic case telescopic ammo LMG in 5.56 is a signification weight reduction from the C9 or M249. That makes sense.

But hauling 7.62 rifle to defeat hard plates, which I guess they are referring to the mass produced 10lb ceramic plates made by everyone, is a losing batter. First of all, unless they are going with tungsten carbide tips like the Bofors M99X, the regular hardened steel in the 7.62 bullet size profile is limiting. The current level 4 armour is designed to stop 30-06 AP rounds - the amount of hardened steel and mass that can be stuffed into that class of bullet is limiting, which is a factor in punching ceramic. 6.5 will not be any better, it is not any heavier with more mass in the bullet or signification faster. The other issue is that, the troops are weighted down, and they cannot respond to the enemies if they decide to shred their armours and change tactics.

The best way to defeat slow moving heavy armoured troops dragged down by armour is to disable them with more bullets or fragmentation weapons. If the enemies shred their armour and start manevouering fast, you can respond to them with the same weapon systems.

yes but how often one takes a round to the center of the plate like they do on youtube when they shoot rubber dummies wearing armour? supressing fire at best and then shower the target with shrapnel weapons.
 
Massed drone strikes?

A regular small drone is pretty harmless. A hundred coming at you as a swarm, each with a fragmentation device is another matter. No armor can protect you from that
 
Why don't they just design a FMJBT 77gr 5.56 bullet? The spf rifles that shot 77gr OTM were effective to 500y. An FMJBT wouldn't be as accurate as the OTM bullet, but it would have the extended range and damage for longer range gun fights.
 
That said, 5.56 should be around for another 50 years or so until they release reliable caseless munitions or phased plasma rifles in the 30 watt range.

This is pretty much my thinking, and when the M4 is good enough to do the job most of the time why go to the huge expense of buying rifles that are only marginally better.

Spend the time and money getting the technology right while we can, before the immediate need exists in the future.
