GULFSTREAM WILL deliver the first of two GIV-based signals-intelligence (SIGINT) aircraft to Sweden in August, and is talking to Germany, the UK and Japan about supplying similar aircraft. The company has teamed with US SIGINT-systems manufacturer TRW to market the special-mission version of the GIV business-jet.
Flight-testing of the modified GIV is under way at Gulfstream. The TRW SIGINT systems will be installed in Sweden. The aircraft, designated TP 102Bs, are scheduled to enter service in 1997-8, replacing TP 85 Caravelle SIGINT aircraft.
Germany has SIGINT and battlefield-surveillance requirements. The latter need is similar to the UK's airborne standoff radar (ASTOR) programme. Gulfstream is providing aircraft data to both UK teams, led by Loral and Raytheon, now working on 17-month ASTOR study contracts.
The US aircraft manufacturer says that Loral has requested data on the GIV and the long-range GV now under development. Gulfstream says that a recent record-breaking flight, during which the GIV reached 54,000ft (16,500m), confirms the aircraft's ability to carry a sensor payload to a stable orbit at 47,000-49,000ft to provide the required radar horizon.
The UK may buy up to five ASTOR aircraft, for entry into service by 2001 - although it is likely to abandon the programme in favour of joining the NATO JSTARS project if it comes to fruition. Gulfstream is also offering the GIV as a replacement for the Royal Air Force British Aerospace Nimrod R.1 SIGINT aircraft lost in an accident in May. The aircraft would augment the two surviving R.1s.
The Japan Air Self-Defence Force plans to acquire up to nine GIVs, designated U-4s, configured as quick-change passenger/cargo aircraft, and it requires SIGINT platforms, Gulfstream says.
