The Czech military has purchased two Israeli-made Skylark II unmanned surveillance aircraft.

The two surveillance aircraft bought for CZK50m (about $3m) is intended for day, night and adverse weather real-time reconnaissance, data collection and target marking in support of military and para-military forces.

The close-range tactical unmanned aircraft built by Elbit Systems can be operated in low and medium altitudes for secret missions that cannot be accomplished by any other monitoring systems.

The Skylark II features a payload of 10kg, flight endurance of six hours and a ceiling of 15,000ft, while providing real-time imagery and video as well as GPS positioning.

The Czech defence ministry recently purchased six US remote-controlled miniature Raven unmanned aerial vehicles worth CZK20m.
