The Airborne Stand-off Radar (ASTOR)
is a new British capability for operations over and around the battlefield.
It is to form the UK equivalent to the US E-8 Joint Surveillance Target
Attack Radar System (JSTARS).
ASTOR is to provide a long-range all-weather theatre surveillance and target acquisition system capable
of detecting moving, fixed and static targets.
It is designed to meet
a joint Army and RAF requirement. The production contract was signed
in December 1999 for the supply of five air-platforms, eight ground stations,
and contractor logistic support. The principal elements of ASTOR are
the Bombardier Global Express aircraft, to be know as Sentinel R1 in
RAF service, and the Raytheon ASARS-2 side
looking airborne radar used on the U-2.
 |
The radar operates at
high altitude and in all weathers to provide high resolution. ASARS-2
has been reported to provide images of the battlefield at ranges of
160 km, at altitudes up to 47,000 feet. High speed data links transfer
the data from aircraft to ground stations in near real time.
The system
has directional and broadcast data links which are interoperable with
existing US U-2Rs, JSTARS and command and control networks. The
first aircraft are due to received by No 5 (AC) Squadron in
early 2007. Full operational capability should be achieved by
2008. The main ASTOR operating centre will be based at RAF Waddington
in the UK. The projected procurement cost is just over £1bn.

COMMERCIAL ASPECTS
Bids for the ASTOR contract were received from Lockheed Martin, Northrop
Grumman and Raytheon. As with all decisions of this significance,
many related issues required careful consideration, but on 15 June
1999, after a hard fought competition, the Defence Secretary announced
that MOD’s preferred bidder was Raytheon Systems Limited.
Negotiations between
the DPA and Raytheon have been completed, and the contract was signed
at a ceremony at Abbey Wood on 17 December 1999.
The system solution makes
extensive use of commercially available equipment to minimise risk
and cost.
The Raytheon consortium
includes Short Brothers, Motorola UK, GEC Marconi Avionics and Marshal
SV. The participation of these companies, and others, ensures there
will be a substantial UK industrial participation in the execution
of the contract. The project management team will be located in the
United Kingdom and the prime contractor will place work representing
100 per cent of the contract value with firms here.
ASTOR will provide
British industry with valuable high-technology work. The company estimates
that the project will create or sustain around 2,500 jobs in the UK.
This not only safeguards jobs but also provides high value export
potential, ensuring, the UK remains at the forefront of defence technology.
