HMS Ark Royal IV and HMS Eagle were the only 2 Royal Navy decks capable of operating the heavier fast jets, (F4K and Buccs), all the the other RN carrier classes of that era were too small for the bigger jets and would have required major and unrealistic reconstruction. Ark Royal was converted to operate F4K's but Eagle was not, although she continued to operate Buccs for some years. CV01 was planned to replace Ark Royal but financial and political pressure, and a withdrawal from empire removed the perceived need for a CV type replacement, so we opted for the Invincible class of boats with Harriers instead. HMS Hermes was converted to Cdo Carrier to replace the aging and worn out HMS's Bulwark and Albion, both of which were placed in reserve, until scrapped. The other larger fixed wing carriers of that era, HMS Victorious was scrapped in 69, HMS Eagle was scrapped in 78 and Ark Royal went to scrap in 1980. All the other decks that still survived in the 1950/60's were were either sold on to other nations, and some subsequently sold on again to yet other nations, or scrapped before the fast jet era got under way. HMS Triumph hung around until the 1980's, used as dockyard lay apart storage, not actually serviceable. The MOD did consider getting HMS Bulwark back to sea for the Falklands War in 1982, but she too far gone by then to be of any use.
