The M3 Carl Gustav is an upgraded variant of the Army’s Multi-Role Anti-Armor, Anti-Personnel Weapons System, or MAAWS – a reusable, recoilless shoulder-fired conventional munition.
It was first ordered by the Army in response to an Operational Needs Statement from Afghanistan seeking to procure a direct fire, man-portable, anti-personnel and light structure weapon able, among other things, to respond to insurgent rocket-propelled grenade, or RPG, fire.
The latest version, or M3E1, is not only lighter, but shorter than the existing M3 but also ergonomically designed with a longer handle and better grips. These features, as well as its ability to use multiple types of rounds for firing, has led the Army to approve a requirement for 1,111 M3E1 units, service statements said.
Responding to soldier feedback, Army and Saab engineers designed a titanium updated M3E1 that is more than six pounds lighter than the bulkier M3 version. The M3E1 is also 2.5 inches shorter and has an improved carrying handle, extra shoulder padding and an improved sighting system that can be adjusted for better comfort without sacrificing performance.
The M3E1 is part of the Product Manager Crew Served Weapons portfolio, which is processing a contract to procure 1,111 M3E1s and an Urgent Material Release to field them as soon as possible, service statements said.
The new variant is “seven pounds lighter than the M3 – it can be carried safely while loaded – it has advanced fire control – and it has an adjustable shoulder rest and front grip,” Wes Walters, Executive Vice President of Business Development for Land Domain with Saab North America, told Scout Warrior.
The M3E1 is also compatible with intelligent sighting systems for firing programmable rounds.
The weapon includes an airburst capability with its High Explosive, or HE, round.
Army weapons developers say the airburst round is the one that is utilized most often because of its effective range. It uses a mechanical time fuse which is set prior to loading the weapon system.
Airburst rounds can be pre-programmed to explode in the air at a precise location, thereby maximizing the weapon’s effect against enemy targets hiding, for example, behind a rock, tree or building.
The weapon has been used by U.S. Army Rangers, Navy SEALs and Special Forces since the late-80s. In 1988, U.S. Special Forces identified a need for a shoulder-fired, recoilless rifle to replace the M67, and Saab Dynamics developed the M3, which was a likely candidate to address the need.
Earlier versions of the anti-armor, anti-personnel, shoulder-fired multi-role weapon is 42-inches long weighs 21 pounds and can fire up to four rounds per minute.
MAAWS can utilize thermal sights to provide Soldiers with the ability to shoot at night and reach the proper range.
The MAAWS is able to fire anti-tank, flechette, illumination, enhanced armor, smoke and High Explosive Dual Purpose rounds, Army developers explained.
“The High Explosive Dual Purpose round gives you two different capabilities. In impact mode, the round goes off immediately as soon as it hits the target. In delay mode, the round penetrates the target and then goes off,” a service official explained.
