The United States Marine Corps is following in the US Army in the procurement of the Saab M3A1 MAAWS (Multi-Role Anti-Armor/Anti-Personnel Weapon System) recoilless rifle. The M3A1 is a lightweight multipurpose explosive projector weapon which can engage targets at much longer ranges than weapons currently in service with the USMC. The previous MAAWS version, the heavier M3, has been in US Army service since 2011, and was approved for general issue to Army platoons in early 2016.  Military.com’s Hope Hodge Seck reports:

Good things come in lightweight, 84mm packages: Following its fielding of the M3 MAAWS last year, the US Army has announced its decision to sole-source 1,111 improved lightweight M3E1 MAAWS recoilless rifles from Saab Dynamics, in a listing at FBO.gov. The new weapon is based on the Saab Dynamics M4 variant of the venerable Carl Gustaf recoilless rifle, which improves over the previous M3 by reducing weight by 30% (22 pounds down to 15.4 pounds) and length by 14% (1,100mm down to 950mm). The M3E1 is expected to be type classified as the M3A1 Multi-Role Anti-Armor/Anti-Personnel Weapon System (MAAWS).

We all know how awesome the A-10 and GAU-8 is in aviation history. It is a flying gun. Well apparently it is not the first plane built around a gun. The Germans made something similar back in 1942. Henschel built the HS129.
