A navalised aircraft (or navalized aircraft) is an aircraft that has been specifically designed for naval use, in some cases as a variant of a land-based design. An aircraft based on an aircraft carrier is called carrier-based aircraft.
A navalised aircraft typically differs from its land-based equivalent by:
For safety reasons, the aviation fuel provided by ships may be different (e.g. AVCAT) from that provided by airfields and tanker aircraft.
The T-45 Goshawk is a navalised version of the BAE Hawk jet trainer. Differences from the Hawk include changes to the undercarriage for aircraft carrier compatibility and a strengthened airframe. The engine design was also modified for the aircraft's role at sea. A proposed navalised version of the Alpha Jet would have had similar design modifications.
Other examples of navalised variants of land-based aircraft include:
