Boeing, Nammo conducted successful new generation Ramjet 155 artillery tests

In Norway, a team from Boeing and the Norwegian company Nammo has conducted ground-fire tests of their Ramjet 155 Extended Range Artillery Projectile.

This is stated in the report of Boeing.

The Ramjet 155 Extended Range Artillery Projectile – a technology to enable long-range precision fires, one of the U.S. Army’s key modernization priorities.

Successful tests demonstrated the gun-launched survivability and performance predictions.

“We are very encouraged by the development progress, maturation and ongoing testing of our Ramjet 155 projectile, which we believe will offer a superior, affordable capability against emerging threats,” said Steve Nordlund, Boeing Phantom Works vice president and general manager.

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.

“We are seeing excellent progress in the development of the ramjet, with no major stumbling blocks,” said Nammo CEO Morten Brandtzæg. “The latest tests have been extremely promising.”

Since 2019, Boeing Phantom Works and Nammo have been working together to jointly develop and produce the next generation of boosted artillery projectiles to meet the US Army’s long-range, precision-fire requirements.

The program was established on the success of Boeing’s Joint Direct Attack Munition (JDAM) and Small Diameter Bomb (SDB) programs.

The team plans to further develop and test extended range artillery projectile in the coming months.

The new generation of projectiles will be compatible to use with all guns of type L52 (155-mm).

In 2019, representatives of Nammo said that with their engine projectiles will reach a maximum range of about 150 kilometers.
