Description
The XM307 Advanced Crew Served Weapon (ACSW) was a developmental 25 mm belt-fed automatic grenade launcher that resulted from the Objective Crew Served Weapon (OCSW) project. It was under development by General Dynamics Armament and Technical Products for the U.S. Army Tank-Automotive and Armaments Command (TACOM) as part of the Small Arms Master Plan (SAMP) program. The development phase was funded through fiscal year 2007 in May 2004, and funding for a remote-control vehicle variant was granted in December 2005. The project was canceled in 2007 due to the low rate of fire of the prototypes.
The XM307 is a 25 mm belt-fed automatic grenade launcher with programmable airburst capability. It was designed to be lightweight and portable by a two-man team, and also vehicle mountable. The system weighs 50 lb, including the gun, mount, and fire control, which provides a full solution for day and night use. It has a cyclic rate of 250 rounds per minute and an effective range of up to 2,000 meters, where it can kill or suppress enemy combatants, while at 1,000 meters, it can destroy lightly armored vehicles, watercraft, and helicopters. The weapon fires 25 mm ammunition including:
-
high-explosive airbursting
-
armor-piercing
-
training ammunition (HE, AP, TP, TP-S)
-
HEAT
Its recoil system enables mounting options such as small unmanned vehicles and aircraft. Airburst rounds facilitate bypassing cover to engage targets. Gun dimensions are 9.9 W × 7.2 H × 52.3 L inches (43.3 L charged), with dispersion less than 1.5 mils one sigma radius. It uses a weapon-mountable ammunition can for left-side feeding.
An additional feature of the XM307 is its ability to be converted into the XM312, a 12.7 mm (.50)-caliber version, for infantry and light anti-armor support. A Remotely Operated Variant (ROV) intended for the Future Combat Systems family of vehicles was also under development, and was planned to be mounted on a vehicle and remotely operated from within.
