800 NAS were reluctant to carry out many CAS missions because the the Captain and Wings on Hermes thought that low level CAS would be dangerous without someone in a rear seat. This was becuase Hermes' Captian and Wings were from the Buccaneer world. 801 NAS were a little more adventurous but were tied up most of the time providing CAP. The Harrier GR.3's were few in number and as has been mentioned were vunerable to AA fire. Its important to remember that the the Royal Navy intially only had 20 Sea Harriers and 4 Harriers, these were vital to the British campaign and would not be risked to often. One advantage that the British did have was the ability for night strikes which the Argentinean aircraft largely lacked, the exception being the Super Etendard which were thin on the ground. Of course its downright dangerous to fly CAS sorties at night, there's simply to great a risk of hitting your own people because of the small distances involved. It might be risked if there was a good moon though. The British did have an advantage in terms of CAP though, because of the Blue Fox Radar, superior avionics (the computer and Head Up Display really were excellent) and to a certain extent the AIM-9L. The combat pairs employed by the British also worked well and the Sea Harrier had proven an excellent dogfighter. The Argentinean Aircraft's speed advantage was lost when comat needed to be joined because you cannot fight at supersonic speed. The Argentineans were forced to fight in the Sea Harriers element when they wanted to engage the British.
