Boeing, Nammo Test Ramjet 155 Extended Range Artillery Projectile

A team from Boeing and the Norwegian company Nammo has conducted successful ground-fire tests of its Ramjet 155 Extended Range Artillery Projectile – a technology to enable long-range precision fires.

The tests, led by Nammo and conducted during the months of January and March in Norway, validated gun-launched survivability and performance predictions.

Since 2019, Boeing Phantom Works and Nammo have been working together under a strategic partnership to jointly develop and produce the next generation of boosted artillery projectiles to meet the Army’s long-range, precision-fire priorities. Ramjet 155 uses an engine in which the air drawn in for combustion is compressed solely by the forward motion of the projectile at supersonic speeds. The program builds on the success of Boeing’s Joint Direct Attack Munition (JDAM) and Small Diameter Bomb (SDB) programs and addresses range, accuracy and volume of fire gaps between current artillery systems and those operated by potential adversaries.

The team continues to develop and mature the technology, with further testing and demonstrations planned in the coming months.
