Rick a couple of pics of back seat and comparison of Mk2 vs Mk 5.
Business end of ASW SK. Observer, (Obs. or 'Looker') on the left. 17inch fresnel radar. navigation, weapons and comms switching above!
Above the Sonar Op is the HF radio fit, bathythermograph, comms station and a bunch of switching I have forgotten after 30 years!!!
Sonar position with 195(M) sonar. (M) for modified. Which gave the operator the option to select a narrower angle which meant more power down a bearing and therefore greater range. As fitted to the SK Mk's 2 & 5. Mk 6 and a few Mk5s had a different sonar suit with a QUERTY key board and a MFD rather than two cathode ray tube displays. (MFD - Multi Function Display)
The two orange displays are way too bright, I suspect for effect! One display gives range, the second gives bearing left/right of a centre line. The circular display above the two oblongs is the direction control for the sonar. It searches in 90 degree sectors which can 'jump' in 90 degree increments or can be manually changed as the operator is doing to achieve a specific direction.
Any sonar contact can be selected and then that contact can be transferred over to the observers radar so the observer can then take tactical control of the situation.
SK showing dipping sonar below helicopter. Recovery is the most delicate part of the operation as any large swing on the Transducer can damage the hull. Note the colour is vastly different to how Airfix show it.
Below, a comparison of Mk5, bottom SK in the stack, the remainder are all Mk2's. Main differences is the shape of the radar dome. and the aerials beneath the aircraft following the upgrade to be used for passive sonics. (Sonobuoys).
Sorry about the poor image quality, the weather was crap, low cloud - well - just a dismal day on the West coast of Scotland.
Hope they are of some use Rick.
