Quite a few mentioned here.

GREEN PALM - VHF comms barrage jammer (Mks 1A & 2 V-Bombers)
BLUE DIVER - metric barrage jammer* (Mks 1A & 2 V- Bombers)
BLUE SAGA - passive RWR (Mks 1A & 2 V-Bombers)
RED SHRIMP – S (or E)-band barrage jammer (Mks 1A & 2 V-Bombers)
RED STEER Mk 1 - tail warning radar (Mk 2 V-Bombers)
RED STEER Mk 2 - tail warning radar (Mk 2 V-Bombers)

.....Figure 1 shows the locations of the Vulcan’s main jammers. In the early days there was a VHF communications jammer, ARI 18074, known as GREEN PALM; it is not actually shown in the diagram but its antenna was at the top of the fin. ARI 18075, BLUE DIVER, had notched aerials at the wing tips, and the ARI 18076, RED SHRIMP, antennas were normally located on the flat plates between Nos 3 and 4 engines, although most of the BLUE STEEL aircraft had them between Nos 1 and 2 engines as well. The jammer power units and the transmitters were housed in the large cans within the tail bulge. All of this kit had been specifically designed to counter the Soviet high level threats of the 1950s but they were of rather less value once the force had adopted low level tactics.

Figure 2 is a closer view of the tail showing the massive size of the power units and the transmitter cans of the DIVERS and SHRIMPS. I do not recall ever actually knowing what their total weight was, but it must have been several thousand pounds. In fact it was 1978 before I came to appreciate just how big those cans really were.

We had lost an aircraft just outside of Chicago and I was involved in the Board of Inquiry. Apart from the engines and the undercarriage units, the most substantial pieces of wreckage were the cans and I was responsible for making sure that they were returned safely to the UK. They each stood about 31⁄2 feet high and had a diameter of about 2 feet – about the size of a domestic dustbin. They drew a lot of electrical power in their transmit mode, the total load on the aircraft being about 40 KW, which went some way to explaining why the Vulcan B.2 was blessed with four engine-driven 40 KvA alternators.

The biggest single consumer of power in the Vulcan, however, was the Vapour Cycle Cooling Pack, the VCCP. Located towards the rear of the tail compartment, it circulated a water-glycol mixture around the ECM cans. The VCCP drew about 8-10 KW in normal running, but a massive 40 KW on start-up. You will recall that reference has previously been made to the constraints imposed on the employment of EW equipment by the limited power supplies of earlier aeroplanes. Power was no longer a problem with the V-bombers, but heat dissipation was – hence the VCCP.......

Rainbow Code

The Rainbow Codes were a series of code names used to disguise the nature of various British military research projects. They were mainly used by the Ministry of Supply from the end of the Second World War until 1958, when the ministry was broken up and its functions distributed among the forces. The codes were replaced by an alphanumeric code system.....
