Raytheon Is Developing A Ramjet Artillery Round For The Army's New Super Howitzers

The U.S. Army has hired Raytheon, working in partnership with the Netherlands Organization for Applied Scientific Research, to begin developing a new 155mm ramjet-powered long-range artillery round able to hit targets more than 60 miles away. This is one of a number of novel ammunition types that the service is now exploring as companions for its future long-range 155mm howitzers.

Raytheon announced it had received $7.9 million from the Army to get started on the ramjet artillery shell, also referred to as the XM1155, on May 11, 2020. The Netherlands Organization for Applied Scientific Research, better known by the Dutch acronym TNO, will be responsible for developing the ramjet engine. Raytheon will then integrate that into the rest of the projectile, which it will design and build.
