Operational historyEdit

AzerbaijanEdit

On September 12, 2011, a UAV was reportedly shot down by the ARDA over the airspace of the unrecognized Republic of Artsakh.[1] Preliminary investigations carried out by the ARDA have determined the model to be a Hermes 450 type.[2]

GeorgiaEdit

On April 2008, amid Georgian and Russian spy plane shootdowns, three Elbit Hermes 450 were shot down by Russian forces, one by a Mig-29 and other two by ground fire.[3] The Russian Ministry of Foreign Affairs stated and showed the debris of two Herbil drones shot down on March 18 and April 20 with serial numbers 551 and 553 respectively.[4] A UNOMIG mission report said that the panel found the debris of at least three Georgian Hermes 450 drones shot down on 18 March, 20 April and 12 May 2008. Azbakhian forces claimed 7 drones shot down.[5]

IsraelEdit

Israeli Hermes 450 UAVs has seen service in the Gaza Strip operations, the Second Lebanon War as well as in the 2009 Sudan air raids.[6][7][8]

Three Hermes 450 drones were lost during the 2006 Lebanon War, two by technical difficulties and one by a operator error.[7]

On 11 July 2015, an Israeli Hermes 450 drone was reported crashed near Tripoli port, Lebanon. The drone was 8 meters under water and was retrieved by the Lebanese Army.[9][10]

On 31 March 2018, an Israeli Hermes 450 drone crashed due to a technical failure. An additional Israeli drone bombed the crashed drone. The Lebanese Army issued a statement saying that the crashed drone was found to be equipped with four unexploded ordnance. A technical unit of the Lebanese Army detonated it.[11]

United KingdomEdit

The Hermes 450 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.[12] Of the 52 operated by the British in Afghanistan and Iraq, seven have crashed in Afghanistan and one in Iraq.

Former operatorsEdit

  United Kingdom

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.[30] 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.[31] 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.[32]
