 Israel

• The Israeli Air Force, which operates a Hermes 450 squadron out of Palmachim Airbase south of Tel Aviv, has adapted the Hermes 450 for use as an assault UAV, reportedly equipping it with two Hellfire missiles or, according to various sources, two Rafael-made missiles. According to Israeli, Palestinian, Lebanese and independent reports, the Israeli assault UAV has seen extensive service in the Gaza Strip and was used intensively in the Second Lebanon War as well as in the 2009 Sudan air raids. Israel has not denied this capability, but to date, its policy has been not to officially confirm it either.

Former operators

 United Kingdom

• The H450 was operated by the 32nd Regiment Royal Artillery of the British Army on military operations in Afghanistan, supplied under a leasing contract starting July 2007 from a Thales/Elbit consortium.^[18] Eight H450s operated by the British crashed in Afghanistan.^[19] The British version was the only Hermes to use laser gyroscopes in its inertial navigation system. It did not have 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.^[20] 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.^[21] 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.^[22]
