Operational trials with the British Army’s Watchkeeper unmanned air system (UAS) remain on track to start next month, after the WK450 air vehicle has set a new endurance record in testing.
Maj Matt Moore, SO2 UAS for headquarters, Royal Artillery, said a WK450 completed an almost 14h flight in early September from West Wales airport.
With current approvals restricting test flights to daylight hours only, the aircraft landed with around 4h of fuel remaining, he said.
During the record-breaking UK flight, the aircraft’s dual mission payload of an Elop Compass IV electro-optical/infrared camera and Thales I-Master/Viper synthetic aperture radar/ground moving target indication sensor were employed, along with its data link.
The UAS was also taken to its 16,000ft (4,880m) service ceiling and 115km (62nm) away from the airport, Moore told the UK Air Warfare Centre’s remotely piloted air systems symposium in Shrivenham, Wiltshire, on 8 September. The aircraft also flew using its operational-standard software, prime contractor Thales UK said.
Operational trials with the Watchkeeper will be conducted in October and November, with the first training flights over Salisbury Plain to be made from the Ministry of Defence/Qinetiq Boscombe Down site in Wiltshire in December.
Watchkeeper vehicles and equipment will be deployed to Afghanistan from late this year, to deliver one daily “task line” from the first quarter of 2012. A full service using six task lines should be in place within 12 months, Moore said.
In addition to continuing flight testing, other Watchkeeper activities currently include preparing modifications – such as the addition of covert lighting – for deployment in Afghanistan, Moore said.
Development testing with the WK450 has now passed 230 flights and 320h in the UK and Israel.
Thales UK/Elbit Systems joint venture Utacs is responsible for delivering the Watchkeeper system, which will replace an interim service in Afghanistan currently using leased Elbit Hermes 450s.
The service has delivered 50,000h of intelligence, surveillance, target acquisition and reconnaissance services for the British Army since April 2007.
