Northrop Grumman Completes Successful Testing on Solid Fuel Ramjet Concept (SFRJ)

Northrop Grumman Corporation successfully completed multiple rounds of tests on its Solid Fuel Ramjet (SFRJ) tactical engine configuration – a technology to enable long range precision fires, one of the U.S. Army’s key priorities. Conducted as part of phase one of the U.S. Army’s XM1155 Extended-Range Artillery Projectile (ERAP) program, the SFRJ tests validated gun-launched survivability and performance predictions, and demonstrated the potential of extending projectile range to more than 100 kilometers, which is a significant increase compared to current fielded artillery projectiles.

“Successful completion of the rigorous tests of the Solid Fuel Ramjet demonstrates maturation of the technology to survive the very challenging gun-launch environment and significantly extend the range of the U.S. military’s current field artillery with a high level of confidence,” said Pat Nolan, vice president, missile products, Northrop Grumman.

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. 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 began the first phase of developing the XM1155 Extended-Range Artillery Projectile under a $7.9 million U.S. Army contract in May this year.

The XM1155 Extended-Range Artillery Projectile (ERAP) program will provide an extended range, guided 155mm artillery round capable of defeating moving and stationary targets in all terrain and weather conditions. The munition system is being designed to provide multi-domain battlespace dominance against high level targets. Work under the contract will be completed at the Allegany Ballistics Laboratory in Rocket Center, West Virginia, Ronkonkoma, New York; Plymouth, Minnesota; and in partnership with SPARC Research based out of Warrenton, Virginia.
