The AAI Aerosonde is a small unmanned aerial vehicle (UAV) designed to collect weather data, including temperature, atmospheric pressure, humidity, and wind measurements over oceans and remote areas.

The Aerosonde is powered by a modified Enya R120 model aircraft engine, and carries on board a small computer, meteorological instruments, and a GPS receiver for navigation.

On August 21, 1998, a Phase 1 Aerosonde nicknamed "Laima", after the ancient Latvian deity of good fortune, completed a 2,031 mile (3,270 km) flight across the Atlantic Ocean.

The catapult-launched air vehicle has a takeoff weight 34.1 or 36 kg (75 or 79 lb) depending on engine type, with endurance of over 10 hours and an electro-optic/infrared and laser-pointer payload.
