Northrop Grumman has secured a $40.6 million US Army contract for M1156E4 Precision Guidance Kit development, expanding capabilities for new artillery systems. Learn more about this major upgrade.
Northrop Grumman Defense Systems has been awarded a US Army contract valued at $40,600,169 for development, qualification and production of the M1156E4 Precision Guidance Kit (PGK).
Current production versions of the M1156 are optimised for 155mm/39cal artillery systems including the M777 Light Towed Howitzer (LTH) and M109A6/A7 Paladin self-propelled howitzer (SPH).
The M1156E4 is essentially an Engineering Change which will allow for projectiles fitted with the PGK to be fired from the new Watervliet 155mm/58cal Extended Range Cannon Artillery (ERCA) which will be fitted to the M109 series under a major upgrade.
