Iran has presented its largest yet home-made Unmanned Aerial Vehicle (UAV), named "Fotros". This UAV can fly at an altitude of 25,000 feet, has a flight endurance of 16-30 hours, and effective operational radius of 2,000 kilometers. It has been designed to carry out IRS missions, but can also perform combat operations air-to-surface. For the moment, Fotros will be used for surveillance of sea and land borders, oil and gas pipelines, as well as monitoring of post-earthquake disaster areas.
