The urgency to upgrade the radar fitted on the UK RAF Sentinel R Mk1 ground surveillance aircraft is building.
UK MoD funding for the Integrated Radar Programme (IRP), which will see much needed improvements added to Airborne Stand-off Radar (ASTOR) system that gives the aircraft its capability, is expected in 2017.
Meanwhile Raytheon UK, which provides the radar, is preparing for the go-ahead. A spokesperson from the company said it was working with the RAF on the requirements.
This follows the award of an integrated service and support contract in October for the continued maintenance of the Sentinel aircraft
