During the June 28 test at the Andøya Test Center in Norway, a Boeing Ramjet 155 projectile was fired out of a cannon and its ramjet engine ignited successfully. It demonstrated flight stability with a well-controlled engine combustion process.
We believe the Boeing Ramjet 155, with continued technology maturation and testing, can help the U.S. Army meet its long-range precision fires modernization priorities. This successful test is evidence that we are making great progress.
Steve Nordlund, Boeing Phantom Works vice president and general manager
This is a historic moment for Nammo. The test results demonstrate that ramjets are viable and can fundamentally change the future of artillery.
We have great confidence in the ramjet concept. The test – with all aspects from cannon firing, to the projectile body, fins, and trajectory all functioning perfectly – represents a real technological breakthrough in artillery, and a major success for Boeing, Nammo, and the U.S. Army.
Morten Brandtzæg, Nammo Chief Executive Officer
The long-range test at Andøya follows years of research, development and testing by Boeing and Nammo of ramjet technology, including more than 450 static or short-range tests.
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. Considered a hybrid between guided artillery and missiles, the program has an objective of a common round design that can be used in L39 and L58 cannons.
The team continues to develop and mature the technology, with further testing and demonstrations planned in the coming months.
