There were protests this week at the Lichfield site of UAV Engines, the Israeli owned company that manufactures engines for a variety of drones, including the much delayed Watchkeeper drone.
Watchkeeper is a joint venture between Elbit Systems of Israel, and Thales, a French arms company. UAV Engines, of Lichfield (known as UEL) is a subsidiary of Elbit. Engines from this plant are apparently also used in the Hermes drone, which was used in the attack on Gaza recently, and in other aspects of the occupation of the West Bank and Gaza. Israeli sources periodically deny this, but at other times appear to confirm that the motor made in Lichfield is indeed used in the ubiquitous Hermes 450.
The British Watchkeeper drone is based on the Hermes 450.
