The Nammo Space designed and manufactured 317 second Isp, MON/ Hydrazine dual mode apogee engine delivers a thrust of 635 N.

Nammo has supplied the LEROS 1b engine in large quantities, which have flown successfully on deep space missions and telecoms platforms.  The JPL Juno mission to Jupiter used a LEROS 1b engine, which was highly praised for its faultless and predictable performance on this demanding 5.5 year mission.  The LEROS 1b engine has also successfully completed interplanetary missions to Mercury and Mars.

This renowned LEROS apogee engine is the default selection for deep space and Earth orbital missions where high thrust and reliability are crucial to the mission success.  The base material for the thrust chamber and expansion cone is C103 Niobium alloy, coated with R512E Disilicide for oxidation protection.

All Nammo apogee engines are hot-fire tested in the UK National Space Propulsion Test Facility at Nammo Westcott.  Delivery timescales are typically 12-18 months.
