General Dynamics is displaying ENVOY tandem-rotor armed UAV fitted with Thales LMM missiles at the 2026 Farnborough International Airshow.
General Dynamics Mission Systems put the ENVOY tandem-rotor UAV based on Laflamme LX300 on display with the multirole LMM (Martlet) missiles from Thales during FIA2026. The LMM missiles are mounted with twin-tube racks.
ENVOY is a collaboration between General Dynamics Mission Systems (GDMS) and Laflamme, which previously developed the RUAV platform as LX300. ENVOY can carry a payload of up to 180 kg, including weaponry, sensors, and utility payloads. The tandem rotor configuration well known with the CH-47 Chinook cargo helicopter has the advantage of maximising useful internal volume by forgoing the tail rotor as the contra-rotating blades balance the torque.
LMM is a prominent missile in the UK service as a dual-purpose weapon that can engage small surface targets and low-flying aircraft. The missile’s small frame and light weight allow it to be carried by UAVs, helicopters, and remote-controlled weapon stations.
The missile, with a range of six kilometres and a peak speed of Mach 1.5, uses laser beam riding guidance also present on the Starstreak air defence missile (Another prominent tactical missile in use by the UK). The guidance method mainly has the advantage of resistance against flares and jamming, as a laser beam steers the missile towards the target rather than the target’s heat or radar signature.
