Raytheon Missiles & Defense, TNO unveil new ramjet-powered artillery round

Extended-range munition to double US Army’s reach

Excalibur

The XM1155 will be fired from the same artillery cannon as Excalibur, including the U.S. Army’s new 58-caliber Extended-Range Cannon Artillery.

TUCSON, Ariz., (May 11, 2020) – Raytheon Missiles & Defense, a business of Raytheon Technologies, has begun the first phase of developing the XM1155 Extended-Range Artillery Projectile under a $7.9 million U.S. Army other transaction agreement (OTA) through the Combat Capabilities Development Command Armaments Center at Picatinny Arsenal, N.J. The new, cannon-launched, ramjet-powered artillery round will double the U.S. military’s range to greater than 100 kilometers, delivering precision strikes in all terrain and weather conditions.

Raytheon Missiles & Defense is teamed with Nederlandse Organisatie voor Toegepast Natuurwetenschappelijk Onderzoek, or TNO, an organization based in the Netherlands that will design the ramjet engine. Raytheon Missiles & Defense will integrate the engine with the system’s airframe, seeker, warhead and other components.

“The ramjet-powered artillery round will allow our nation’s military to strike farther and faster than anything our adversaries have in their arsenals,” said Tom Laliberty, vice president of Land Warfare & Air Defense.

The tactical 155mm XM1155 will be able to strike moving and stationary high-value targets on land and at sea. The maneuverable, extended-range airframe will be compatible with legacy and future 155mm artillery systems.

The XM1155 builds on Raytheon Missiles & Defense’s experience with guided projectiles, including the Excalibur® munition, an extended-range weapon that can engage targets precisely at all ranges and in adverse weather.
