FGR 2 Tail Fin housing

[eccmo]

Hi all,

 

does the tail fin housing of the RAF FGR 2 only contain a passive homing device or is it an active ecm pod?  
I tried Google but wasn´t lucky.

 

Maybe someone has the answer.

 

Thanks in advance

Hello Eccmo,

 

The fin top fairing on the later RAF Phantom FGR2 was for the ARI 18228 Radar Warning Receiver. ARI 18228 was fitted to all RAF tactical aircraft from the late 1970's, you'll see its antennae mounted fore-and-aft - in several different ways - on the tails of Buccaneers, Harriers, Tornados, Vulcans, and even on the venerable Canberra PR9.

 

It was neither a passive homing device nor an active ECM device, rather it gave warning of illumination by threat radars in the 2.5GHz to 18GHz range. Cockpit instrumentation consisted of a simple 4" CRT which indicated the relative bearing of the incoming signal, with the length of the strobe line being proportional to the strength of the signal. The system operator also received an audio signal which gave a rough indication of the level of the threat.

 

Hope this helps
