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

5
ACSW FamilyXM307, 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

Convertible

• 5 piece conversion kit
• Cartridge guide
• unload guide
• Bolt
• Sprocket
• Barrel

The SDD Program

• Develop, test and deliver weapons systems
• XM307K50 (XM312) .50 caliber weapon
• XM307 25mm weapon
• Remote operation kits
• Dual feed modules
• Pintles and vehicle adaptors
• Tripods
• Modular target acquisition/fire control simulator
• Increase weapon reliability

13
The SDD Program

• Develop and deliver ammunition rounds
• TP
• TP-S
• HEAB
• AP (Development and early prototype delivery to
  FCS/UA)
• Develop, integrate, test and deliver Integrated
  Logistics Support products
• Operation manuals
• Maintenance manuals

Driving towards Low Rate Initial Production

16
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

17
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

18
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

19
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

20
ACSW Summary

• Provides New Weapon Capabilities
• Passed All ATD Exit Criteria
• Poised for the SDD Phase
• Driving towards Low Rate Initial Production
