New Frontier Aerospace Tests 3D-Printed Rocket Engine for Future Flight Applications

GEEKWIRE - Kent, Wash.-based New Frontier Aerospace says it has put its 3D-printed Mjölnir rocket engine through a series of successful hot-fire tests, in preparation for an initial flight test of a hypersonic drone that could take place as early as next year.

Mjölnir is named after the hammer that was wielded by Thor in Norse mythology (and in Marvel movies). The first job for this hammer would be to propel an uncrewed aerial system called Pathfinder for a series of hovering tests, currently set for 2026. Eventually, Pathfinder could be used for weapons testing or for suborbital point-to-point cargo transport.

The engine is also slated for use on New Frontier’s Bifröst orbital transfer spacecraft, which is due to fly into space by 2027.
