One of the key drones in this class is the Heron, made by the Israeli Aerospace Industries (IAI) - some of which the Bundeswehr is intending to lease. This drone, which weighs over 1,000 kilos and has a wingspan of over 16 meters, can fly for up to 52 hours at a height of 10,000 meters (35,000 feet) - around the same height as a commercial airliner. The US, Canada, India, Turkey, Australia, and Morocco have all bought Herons for tactical and reconnaissance use.
