Thanks for posting more photos. I especially like the Westland Wessex (HAS. 1?) in the first picture. It seems to be carrying French AS.12 wire guided anti-ship missiles and what looks like 2 inch rocket pods (the silver tubes).
Useless information follows (hope you don't mind) ...
AS.12s were used in anger by the British a few years later in the Falklands. Westland Wasp helicopters fired nine of them against the Argentine submarine the ARA Santa Fe which was trapped on the surface and unable to dive after its dive tanks suffered damage from a depth charge attack by a Royal Navy Wessex HAS.3 antisubmarine helicopter (visually similar to the one in your photo but with a radome on the rear fuselage). Out of the 9 missiles 'fired', 4 hit, 4 missed and 1 failed to launch. Two of the missiles that hit failed to detonate on impact, instead punching a hole through the slender conning tower and exploding on the far side.
In an unusual mission, two AS.12s were fired from a Royal Navy Wessex HU.5 commando transport helicopter at Port Stanley town hall on 11 June 1982 in an attempt to disrupt a meeting of senior Argentine personnel that took place there every morning. Both missiles missed, one striking the roof of a police station and the other hitting some telegraph poles.
So not the most accurate (or reliable) of wire guide missiles...
