You may well be correct about the Mk2 using dumb bombs, me not being a "plumber" wouldn.t have known the difference,.
I allways thought Nimrod had a perfectly adequate anti ship weapon in the form of Harpoon at the time, and was trialled to bail out other platforms if it was required.
The only weapon fitted that I can recall that was for its own defence was AIM-9, which we fitted quite a while after Corporate.
