HMS Ocean R68
On 4 December 1945, famed test pilot Eric “Winkle” Brown made the first landing on a carrier by a pure jet aircraft, a DH Sea Vampire, on the Ocean. (Strictly speaking, a Ryan FR-1 Fireball - with a mixture of radial and jet engines - had landed earlier in the same year, after its radial engine failed.)
And it was from the Ocean’s deck that a Swordfish aircraft conducted the type’s last official flight from a carrier.
