GS in the back hatch along with several ECM 'dustbins' Swapping the tray with the two domes was no great problem which was not the case for the back hatch itself. The Dzus fasteners were always a problem, needing a GS screwdriver and hide faced hammer to secure. The riggers were no help and the crew chief kept well away.. The GS aerial was below the back hatch floor, with a waveguide sticking up in a vulnerable place - never saw one damaged though.
Red Steer was the tail warning radar that replaced Orange Putter. If you want another 'colour' try Red Shrimp.
As mentioned above Blue Silk replaced GS for some roles, Slightly different depression angle for the radar beams and different frequency,,. . . . both changes intended to provide better performance over water..
Oh happy days ... driving an RVT with that woolly column gear change with most of a full kit of ECM bins in the back..
