Boeing and Nammo have recently collaborated on a project that promises to redefine the capabilities of artillery systems.

The partnership, aimed at developing a Ramjet 155 munition, has resulted in a record-breaking test of the projectile’s range. While the precise range of this artillery shell remains classified, it is known that the ramjet-powered munition can potentially strike targets at distances exceeding 70 kilometers (43.5 miles).

Nammo goes even further, suggesting that the munition might be capable of hitting targets at an astonishing 150 kilometers (93 miles), depending on the delivery platform.

A Step Forward in Artillery Technology

The recent test, conducted with a 58-caliber Extended Range Cannon Artillery (ERCA), saw the Ramjet 155 munition making history by setting the record for the longest indirect fire test of a ramjet-powered artillery projectile. This milestone marks a significant leap in the development of long-range precision artillery systems.

The Ramjet 155 munition, a key project under the US Army’s XM1155 program, has piqued the interest of the military and defense community due to its innovative air-breathing engine design.

Boeing’s vision for this munition involves using the initial cannon firing to provide the necessary speed for combustion, making it an exceptional choice for long-range precision strikes.

Boeing’s executive director of Phantom Works, Gil Griffin, expressed the objectives of this project, which go beyond the mere achievement of record-breaking range.

“Our objective was to demonstrate the ability to safely operate from the ERCA system and validate our performance. Both objectives were met,” said Griffin in a press release.
