What is acsw
What is ACSW?

ACSW Program Started in 1994

  • Lightweight, Crew Portable

    Weapon System

  • 25mm Family of Ammunition

  • 250 SPM

  • Full Ballistic Solution

  • Programmable Ammunition

    with Muzzle Velocity Correction

  • TA/FCS Laser Range Finder &

    Target Tracking


Acsw family xm307 xm307k50 xm312
ACSW Family:XM307, XM307K50 (XM312)

  • .50 cal variant of the ACSW

  • Part interchangeability with XM307, only 5 parts are different

  • First demonstrated January 7, 2003

  • Performance & physical characteristics exceed other crew-type .50 cal weapons

  • Development of XM307K50 (XM312) will accelerate ACSW maturity

  • Fires standard .50 cal ammunition with M15A2 links

Recovery from disabled vehicle
Recovery from Disabled Vehicle

  • Lightweight capability enables the gunner to remove the weapons system from the destroyed vehicle, thus maintaining the combat power of the convoy


Dismounted overwatch
Dismounted Overwatch

  • The dismounted ACSW provides additional security via a wider and better field of view than vehicle mounted

  • Employment in the 2nd floor is less time consuming and requires less physical effort than dismounting the MK19 or M2

  • Movement from primary to secondary positions is significantly quicker than with the M2 or MK19 because of the weight

  • ACSW tripod does not require sandbags because of low recoil


Action on the landing zone

Scene 2

Scene 3

Action on the Landing Zone

  • Reduced weight enables the gunner to mount the ACSW by himself and in less time, allowing more soldiers to perform security

  • This reduces the time available to the enemy to prepare for a counterattack, thus increasing combat effectiveness


Fast roping the acsw
Fast Roping the ACSW

  • The lightweight ACSW permits the establishment of a blocking position with a heavy caliber or grenade machinegun

  • The capability to fast rope allows a dramatic increase in dismounted blocking position firepower

  • Low system weight allows team to move weapon on ground as needed


Acsw summary
ACSW Summary

  • Provides New Weapon Capabilities

  • Passed All ATD Exit Criteria

  • Poised for the SDD Phase

  • Driving towards Low Rate Initial Production

ACSW: Combat Weapon of the Future
