Raytheon has secured a contract to continue providing Excalibur Increment b (Ib) precision-guided projectiles to the US Army.
The $31.8m contract requires the company to produce and deliver 464 extended-range projectiles.
Raytheon Land Warfare Systems vice-president Duane Gooden said: "There is growing demand in the international market for Excalibur's accurate, first-round effects capability.
"Raytheon has also funded an internal development programme aimed at bringing Excalibur's unprecedented capabilities to the maritime domain."
Developed in collaboration with BAE Systems / Bofors, the Excalibur projectile uses GPS precision guidance to offer accurate, first-round, fire-for-effect capabilities to 155mm howitzers in urban environments.
Equipped with fewer parts, the Excalibur Ib projectile has a simplified development process compared to the Excalibur Ia. It addresses the army's objectives for improved reliability at significantly reduced costs.
Raytheon is currently developing Excalibur N5, a 5in / 127mm variant of the standard version for the US Navy.
In May 2015, the US Army successfully fired two Excalibur Ib precision-guided, extended-range projectiles from a M109A2 / A3 howitzer to confirm that the precision round is now compatible with global artillery platforms.
Excalibur has been fielded by the US Army, the Marines, and several foreign military forces worldwide.
