Raytheon touts future roles for RAF's at-risk Sentinel R1
By: Craig Hoyle London - 15 hours ago
Raytheon UK is eyeing possible applications for the Royal Air Force's Sentinel and Shadow surveillance aircraft, with both types expected to be retired once they are no longer required to support coalition activities in Afghanistan.
Representing combined fleets of 10 aircraft, the manned types provide a key part of the RAF's intelligence, surveillance, target acquisition and reconnaissance (ISTAR) capability.
The Sentinel R1 force comprises five Bombardier Global Express business jets modified to carry a Raytheon synthetic aperture radar/ground moving target indication sensor and onboard stations for two image analysts. The aircraft forms part of the UK's Airborne Stand-off Radar (ASTOR) system, along with supporting ground elements.

With the ASTOR capability having been deemed surplus to requirements post-Afghanistan during the UK's Strategic Defence and Security Review of late 2010, two possible new roles have been suggested. Raytheon believes the system could deliver the UK's contribution to the NATO Alliance Ground Surveillance system, which will also include an expected five radar-equipped Northrop Grumman RQ-4 Global Hawk unmanned air vehicles.
Paul Francis, Raytheon UK's head of airborne solutions, says the Sentinel's dual-mode radar could also possibly be given software-based changes to enable it to provide a maritime patrol capability to search for, track and identify surface vessels.
Raytheon is under contract to provide logistics support for the Sentinel fleet until September 2016, and recently completed a build-standardisation programme on the fleet, performed at its Broughton site in north Wales. The RAF re-accepted the last of these in January, and deployed the aircraft - ZJ690 - in support of its Operation "Herrick" mission in Afghanistan less than two weeks later.
The UK's Defence Equipment and Support organisation says the undisclosed enhancements will provide "a much more robust ISTAR capability to support operations".
Meanwhile, a fifth Hawker Beechcraft King Air 350CER-based Shadow R1 was delivered to the RAF's 14 Sqn at Waddington last December. The unit's earlier examples have now all passed through a "return to works" programme at Broughton, with the process having added some undisclosed new capabilities.
Acquired under urgent operational requirement deals to support the Afghanistan campaign, the Shadow R1 carries an L-3 Wescam MX-15 electro-optical/infrared sensor payload, satellite communications equipment and up to three onboard operators. If retained long-term, the type could possibly also provide a maritime patrol capability by being equipped with Raytheon's SeaVue radar, Francis says.
