ZALA Aero (now a subsidiary of Russia's Kalashnikov Concern) produces the ZALA-421-16 small tactical unmanned air system. The 10 kg UAV has a flight endurance of up to three hours. The aircraft's autopilot navigation system uses both GPS and GLONASS.
The UAV is designed for tactical ground reconnaissance or overwater surveillance. The 421-16EM is catapult-launched from ashore or a boat and recovered with a parachute. The 421-16 features an inflatable buoyancy system that protects it when landing on the water.
