Boeing, Nammo to Integrate JDAM computer onto a Ramjet Projectile for Precision Long Range Fire

Boeing and Nammo will attempt to integrate the mission computer from a Joint Direct Attack Munition (JDAM) onto a Ramjet -powered artillery projectile to achieve precision long range artillery fire.

Boeing on Tuesday announced a new "record' for the longest indirect fire test of a ramjet-powered artillery projectile without specifying the distance achieved. Typically, artillery shells are propelled by the launcher to achieve a distance of around 70-100 km.

However, an artillery projectile that incorporates a ramjet will be able to travel much further. The addition of a mission computer will allow it to correct its course after launch and achieve precision-strike on targets such as a tank on the move.

This test surpasses last year's Boeing-Nammo record, achieved at the Andøya Test Center in Norway using a 39-caliber towed artillery cannon for the longest-ever indirect fire test of a Ramjet 155 munition.

The Boeing-Nammo solution is being developed under the Army’s XM1155 program. Considered a powered guided artillery munition, Ramjet 155 utilizes an air-breathing engine design that uses the cannon firing to provide the speed needed for combustion.
