Apart from aircraft looks just like a WW2 pic makes you wonder.
Given that at this particular moment the sea wolf system had gone offline, and they were inside effective sea dart range, it was pretty much WW2 stuff, just not quite as much of it as a typical WW2 destroyer would have.
On the second pair, of course it was Coventry herself that broke the lock of the sea wolf. A bit like an aircraft accident - rarely is it just down to one single fault but a chain of errors or mistakes that when put together create a disaster. The A4s probably could have been intercepted before reaching the ships, but they were called off. Then, the sea dart wouldn't lock onto the inbounds. Finally, when Broadswords Sea Wolf had locks on them, Coventry steered across the beam and broke the lock and left the pair to make a successful attack and put 3 of their four bombs in to her, which for once, despite the height of release, for once exploded (unlike the ones dropped onto Broadsword). Very unfortunate for Coventry and very fortunate for the two A4 pilots.
