Actually, there was a very good reason for that. See my Post 184.
******************
The British carriers could only launch Harriers for CAP patrols and could not launch Haweyes for EAW. The only warning capabilities were the radars on the Harriers that had no "look down" capabilities.
So, the Argentinians flew their Skyhawks and Daggers at wave top level avoiding detection until the last minute and thus managed to score multiple hits on British ships using "dumb" bombs.
Fortunately for the British, the tactic had the disadvantage that the bombs were dropped at such a low altitude that the fuses did not have time to arm and many bombs therefore failed to explode. Even then, the kinetic energy of the impact caused great damage.

Only reason Argentina would need exploding bombs would be
for Malvinas redux, and I don't believe they are ready
to "Falk" with those islands again..
