US Army's New Super Weapon: Merge a Machine Gun with a Rocket Launcher

The Army is in the early stages of beginning to create requirements for a new externally-mounted weapon to replace both the M2 .50-cal machine gun and the Mk19 grenade launcher.

The idea is to simulteneously lighten the load of mobile attack forces while increasing their lethaltiy and envelope of attack with a single system that achieves the offensive firepower, and desired combat effects, of both weapons. 

“This will be one weapon with a totally different new type of ammo that is not yet even in the developmental phase,” Laura Battista, Product Management Engineer, told Scout Warrior in an interview.

The effort is still very much in the early or conceptual phases, however future engineering and requirements initiatives plan to give shape, contours and direction to the new weapon; as a result, Army officials did not yet specify a timeframe as to when this might be operational. However, it is reasonable to assume that requirements, designs and then prototypes could emerge in the next few years. 

The details of how this will be accomplished have not yet emerged, however the planning is to engineer a weapon that has the attack and suppressive fire ability of a .50-Cal along with an explosive "area weapon" effect of a grenade launcher. 

The new, combined-fires weapons would bring both logistical and tactical advantages. A single unit on-the-move could much more easily attack a wider range of targets with one weapon, bot laying down suppressive fire oar attack with machine gun fire and also achieve the effects of firing grenades at enemy locations when needed.  

Meanwhile, the Army will also embark upon a simultaneous excursion to develop a lighter profile barrel for the .50-cal.

“We will have many barrels that will lessen the logistic burden of having a spare barrel all the time. We are also hoping to save a lot of weight. We are hoping to save 16-pounds off of a 26-pound barrel,” Battista explained.

The Army’s .50-cal program is looking at a longer-term project to engineer a lighter weight caseless ammunition which will reduce the amount of brass needed, Lt. Col. Paul Alessio, Product Manager Crew Served Weapons Alessio, told Scout Warrior in an interview. 

In addition, the Army plans to engineer a laser rangefinder, new optics and fire control technology for the .50-cal. Alessio said a new, bigger machine-gun mounted optic will likely be put on the gun within the next five years.

A laser rangefinder uses an algorithm created to identify the exact distance of a target -- by combining the speed of light, which is known, with the length of time it takes the laser to reach the target.

The new addition to the weapon is called a Mounted Gun Optic, or MMO.

“It is basically an optic or direct view optic which will have some type of laser crosshair. This will improve lethality and an ability to put first round on target,” he added.

Finally, within five to ten years, the Army plans to have some kind of fire control technology added to the .50-cal; this will improve the accuracy of the weapon an increase its effective range by incorporating ballistic calculations such as the round’s trajectory through the air to target, Alessio explained.

New Lightweight .50-Cal

The Army is creating a new, lightweight version of its iconic .50-cal machine gun designed to better enable Soldiers to destroy enemies, protect convoys, mount weapons on vehicles, attack targets on the move and transport between missions.

The new weapon, engineered to be 20-to-30 percent lighter than the existing M2, will be made of durable, but lighter weight titanium, Army officials said.  

The emerging lightweight .50-cal, described as still in its infancy stage, still needs to be built, riveted and tested. 

The parts for the titanium prototypes will be built at Picatinny Arsenal, N.J. and then go to Anniston Army Depot, Ala., for riveting and further construction.

“We always want to lighten the soldier load. A major requirement is to engineer a 60-pound weapon compared to an 86-pound weapon,” Battista said. 

“We will procure 30 and then go into full blown testing - air drop, full reliability, durability, maintainability and government standard testing.  We'll see how it did compared to the M2 and we will try to go to turn it into a program of record,” Battista added.  

An Intimidating and Combat-Tested Weapon:

The M2 crew-served machine gun, referred to as the "Ma Duece," was first introduced in the 1930s'; it has both a lethal and psychological effect upon enemies.

“When enemies hear the sound of the gun, they tend to run in the other direction,” Battista explained.

The machine gun is currently used on Humvees, tactical trucks, M1 Abrams tanks, Strykers, some Navy ships and several aircraft such as CH-47 Chinook cargo helicopters and UH-60 Black Hawks. The gun can also be mounted on a tripod on the ground by infantry in a firefight or combat circumstance; the M2 has a solid range and can fire at point targets up to 1,500 meters and destroy area targets at distances up to 1,800 meters.

The .50-cal is effective in a wide variety of circumstances, such as convoy protection, air attacks and attacks upon small groups of enemies on foot or moving in small vehicles. Several variants of the machine gun can fire more than 500-rounds per minute.
