As one who was there, I can confirm that it was a combined operation of all services. The Wessex of 78 Sqn (of which I was a member) were embarked aboard HMS Intrepid for the final few days and operated from there. Eagle and Bulwark were there up until the end and the RN Wessex were also operating in support. As always in these things, the "poor bloody infantry" had the worst of it, but we did what we could to help. Not our finest hour by a long way, but the political story is someone else's.
