It has an endurance of over 20 hours, with a primary mission of reconnaissance, surveillance and communications relay. Payload options include electro-optical/infrared sensors, communications and electronic intelligence, synthetic-aperture radar/ground-moving target indication, electronic warfare, and hyperspectral sensors.

Overview
The Hermes 450 is a medium-sized UAV with a cylindrical shaped fuselage, high straight wings and a V-tail. It is autonomous from take off to landing, with an auto pilot capable of take off and landing. It can be controlled completely from a ground station.

In 2008, Elbit announced that a new R902(W) Wankel engine, weighing about  and developing  using electronic fuel control, would be used in the Hermes 450.

It has the option of carrying four Rafael Spike missiles.

It is the basis of the Thales Watchkeeper WK450 and Hermes 900 designs.

Former operators

The British version of Hermes 450 was the only Hermes to use laser gyroscopes in its inertial navigation system. The UK Ministry of Defence did not take up the option for wing mounted armament. The Hermes 450 is the basis of the British Army's Watchkeeper WK450, development of which started in July 2005 in conjunction with Thales.  In September 2013, the Hermes 450 reached 70,000 flight hours supporting British troops in Afghanistan, the equivalent of 8 years of non-stop flying.  The British had flown the Hermes 450 more than any other country in Afghanistan. As of January 2014, British Hermes 450 air vehicles flew over 86,000 hours over Iraq and Afghanistan.  Up to nine aircraft operated from Camp Bastion and conducted five flights per day, accumulating a combined 70 hours of surveillance coverage. When the Watchkeeper WK450 entered service in Afghanistan in mid-September 2014 and the ground-based radar coverage at Bastion was switched off, the British Army stopped using the interim leased Hermes 450.
