Nammo advances 155mm ramjet artillery projectile for extended-range fire support
Norwegian munitions maker Nammo is developing new 155mm artillery ammunition that uses ramjet propulsion to extend firing ranges beyond conventional, base-bleed, and rocket-assisted designs. The company showcased the technology at AUSA 2026, combining ramjet research with existing projectile families. Nammo has not disclosed a customer or fielding timeline.
Why it matters: Ramjet artillery shells have been promised for decades and fielded never — Nammo's track record with 155mm makes this one worth watching, but scepticism is warranted until someone fires one.
U.S.-Norwegian startup Heaviside unveils Tyr 2 kg loitering munition with anti-tank warhead
Heaviside Industries, a California-headquartered company with close ties to Norwegian arms-maker Nammo, launched the Tyr loitering munition at the Association of the U.S. Army annual meeting. The fixed-wing munition weighs slightly over two kilograms, offers four modular warhead options including an anti-tank variant supplied by Nammo, and the complete system weighs 6.8 kilograms. Nammo also provides a range in Norway for live-fire testing.
Why it matters: A man-portable loitering munition claiming tank-killing capability at 2 kg puts pressure on European programmes still measuring drone payloads in double digits.

Nammo CEO warns European rupture with U.S. defence industry risks 10-year capability gap
Nammo chief executive Morten Brandtzæg told Breaking Defense that severing the transatlantic defence industrial base would leave Europe a decade behind in key capabilities. He argued the allied industrial ecosystem is already deeply interconnected and cannot be broken apart without severe consequences for European readiness.
Why it matters: The warning lands as European capitals debate sovereign production mandates that would cut U.S. suppliers out of programmes — an industrial divorce Nammo says Europe cannot afford.
