PICATINNY ARSENAL, N.J. -- On April 3, the Excalibur Program completed assembly of the last Increment Ia-2 projectile and transitioned to Increment Ib production.
 
First fielded in 2007, Excalibur is the Army's GPS-guided, precision 155 mm artillery projectile. It couples GPS technology with an inertial measurement unit to provide accurate, first-round fire-for-effect capability in an urban setting with accuracy better than 4 meters Circular Error Probable (CEP).
 
"The successful transition from Excalibur Increment Ia-2 to Ib production is a significant step in the lifecycle of the program," said Lt. Col. Joshua Walsh, Product Manager Excalibur with the Program Executive Office Ammunition at Picatinny Arsenal, N.J. "This new capability provides the Warfighter with increased accuracy and reliability at a reduced cost."
 
This milestone marks eight years of Raytheon Missile Systems (RMS) production and assembly at the McAlester Army Ammunition Plant in McAlester, Okla.
 
More than 6,500 Increment Ia rounds have been delivered to the U.S. Army, U.S. Marine Corps, and several international customers.
