According to the companies, the firing is a record for longest indirect fire test of a ramjet-powered artillery projectile. The distance covered was undisclosed but a company official said it was more than a third longer than than the previous firing.
It took place alongside officials from the US Army and involved firing a Ramjet 155 munition from a 58-caliber Extended Range Cannon Artillery at Yuma Proving Ground, Arizona. The test advances development efforts for the army’s top modernisation priority, Long Range Precision Fires.
The success follows last year’s Boeing-Nammo test recording the longest-ever indirect fire test of a Ramjet 155 munition. That test was completed using a 39-caliber towed artillery cannon at the Andøya Test Center in Norway.
