HMS Ark Royal (R07), the last Invincible-class light aircraft carrier to be completed, is the fifth ship of the Royal Navy named in honour of the flagship of the English fleet that defeated the Spanish Armada. Ark Royal is slightly larger than her sister ships and during construction she was fitted with a steeper ski-jump ramp, (twelve degrees, as opposed to seven degrees of the Invincible) to improve STOVL take-off performance for the Harrier aircraft.
