- Q23003097 abstract "Orange Harvest was an ESM receiver fitted to marine patrol Avro Shackletons during the Cold War.Orange Harvest was an S band and X band radar warning receiver, capable of giving a directional bearing to surface ships or submarines that were transmitting radar emissions. Although less precise than the Shackleton's main ASV.21 search radar, it could give a greater detection range, provided that the target was emitting. As a passive system, it also had the advantage that it did not betray the aircraft's presence to its target.A particular target would be the I band RLK-101 Albatros (NATO Snoop Tray) and MRK-50 Snoop Pair radars used by the early Soviet nuclear submarines. As these boats could now run continually submerged, without even needing to snorkel, they were increasingly difficult to detect by previous methods, such as Autolycus or search radar.Electrically there were two quite separate systems: wide- and narrow-band, but sharing the same external aerial housing. The wide band receiver was made by Rank in Plymouth. The narrow-band receiver was derived from an early ELINT receiver called 'Breton', developed in Comets by 51 Squadron.The external aerial for Orange Harvest was the distinctive white dielectric 'spark plug' carried on the upper surface of the Shackleton. This 'spark plug' has often been mis-identified as an insulator for a HF long-wire aerial running to the aircraft's tail. It is actually self-contained, and at a wavelength far shorter than would use long wires. The Shackleton did carry HF aerials, but these were supported by two small metal masts, just ahead of Orange Harvest. The structural fitment for Orange Harvest was a metal plinth built into the fuselage, at approximately the previous dorsal turret position. The large aerial was fastened to this. As the aerial causes significant drag, it was sometimes removed and only the plinth was evident. This was more common in the 1960s ASW era, rather than the later AEW period.The interior display for Orange Harvest was a 3" cathode ray tube, in front of the C operator.Orange Harvest was introduced with the Shackleton MR.3 Phase II in 1961. After the replacement of Shackleton with Nimrod MR.1 in the ASW role, Orange Harvest continued with the Shackleton AEW.2 aircraft of 8 Squadron RAF from 1972 to 1991.".
