Westland Lynx HAS.3

OK, next off the bench is a Westland Lynx HAS.3 of the 815 Naval Air Squadron, Fleet Air Arm operating from HMS Exeter, April 1987. The white canisters are housings for ships' biscuits and rum...

edit: ok, rum was stopped back in the 70's (thanks f.y.i. Ian)

I am guessing that the white ordinance are anti-submarine torpedo, but despite some research I am still ignorant.
