Deck sized to Navwar's BULWARK N127.
In 1960, Bulwark was recommissioned with 42 Commando Royal Marines and 848 Squadron attached to the carrier. In 1961, due to an increasing threat of invasion of Kuwait by Iraq, Bulwark landed 42 Commando in Kuwait. She also took part in the campaign against Indonesia, during the Indonesian Confrontation. In June 1966 she carried out sea trials with the Kestrel: the forerunner of the Harrier fighter.  In 1972, Bulwark, like her sister ship Albion, was involved in withdrawals across the declining empire.
