In later years, three other changes were made. One was the removal of the Sea Dart system, creating an increased deck park for aircraft. The Sea Dart magazines were converted to increase air-to-surface weapons stowage, and new aircrew briefing facilities created under the extended flight deck, both to support the embarkation of RAF Harrier GR7s as a routine part of the air group. The ships were all fitted to handle [[AgustaWestland EH101|Merlin]] helicopters as the Merlin HM1 replaced the Sea King HAS6 in the carrier-borne ASW role. Following the integration of the Harrier GR7, typical deployments included seven or eight of those aircraft, pushing the Merlin onto the carrier's accompanying [[Fort Victoria class replenishment oiler|''Fort''-class auxiliaries]].

The last wartime deployments of the class saw them in their secondary LPH role, as it was officially judged that Sea Harriers could provide no useful role in the missions. During those deployments, the class embarked RAF [[Boeing Chinook (UK variants)|Chinook helicopters]], in lieu of their fixed-wing complement.

''Invincible''{{'}}s final refit was in 2004.<ref name=ForSale/>

''Illustrious'' underwent a 16-month £40 million refit at [[Rosyth Dockyard]] during 2010 and 2011 in preparation for her new role as a [[helicopter carrier]] during the refit of {{HMS|Ocean|L12|6}}.<ref name="news.stv.tv"/>
