    Wessex HAS1 & HAS3 Sonar Stations - Looking for pictures

    Can anyone come up with any pictures of the sonar panels for HAS1 and HAS3?

    The only ones I can find are photos of museum aircraft XP142 Humphrey and XM328 - both HAS3 and both incomplete. No HAS1 pictures at all. I guess the problem is that the equipment would have been secret at the time.

    XM328 is by far the most complete example, thanks to a donation from a Sea King (Sea Kings having been the recipients of the kit from the HAS Mk.3s when they went out of service - hence why they're all robbed). There is a diagram of the HAS Mk.3 sonar station in the forthcoming Haynes Wessex Manual.....
    The views I express are PURELY my own. Please respect that.

    I joined 737 NAS in January 1967, we had Wessex HAS 1's and the Sonar 195 development Wessex XM328, later we started to get HAS 3's . I don't have a photo of the inside of a HAS 1 but compared to the HAS 3 it was very basic . No Radar, basic autopilot and Sonar 194. The Sonar had a 90 foot cable [ 195 had 300 feet ] with a ball transducer with 4 wooden stabilising paddles. The displays were a bearing indicator and a range display of the 'wet paper' and moving stylus , just like one would see in black and white WW2 movies [ not the same, but almost, http://jproc.ca/sari/asd_et2.html ]. The main AS detection was by the operators ears!, the operators all being 'old & bold' AS sonar operators transferred from RN General Service [ships]. The operator sat left, as where the radar operator does in the HAS 3.
    The HAS 1 equipment certainly wasn't secret, the HAS 3 was, at the time ~ although the spy ring at AUWE Portland ensured the Russians knew everything.

    Long time ago, my memory may lack on the detail side.
