A navalised aircraft (or navalized aircraft) is an
aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engine ...
A navalised aircraft typically differs from its land-based equivalent by:
* The airframe, engine and
avionics
Avionics (a blend of ''aviation'' and ''electronics'') are the electronic systems used on aircraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fit ...
corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engi ...

* It is designed to be used on a
flight deck
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopte ...
. For a fixed wing aircraft this typically means catapult attachment points, a
tailhook
A tailhook, arresting hook, or arrester hook is a device attached to the empennage (rear) of some military fixed-wing aircraft. The hook is used to achieve rapid deceleration during routine landings aboard aircraft carrier flight decks at sea, ...
and strengthened undercarriage. Naval helicopters usually have wheels rather than skids and may have mechanisms to attach to the deck.
* It is designed to occupy minimum hangar space – for example the wings, tail-boom or rotors may fold.
* There is enhanced protection against water ingress (including that from hosing down with fresh water to get rid of salt water).
* Equipment such as sensors and weapons are optimised for naval roles.
* The avionics is compatible with the complex electronic equipment of a warship, and that there is no electromagnetic interference between the two.
* There is provision for
ditching
In aviation, a water landing is, in the broadest sense, an aircraft landing on a body of water. Seaplanes, such as floatplanes and flying boats, land on water as a normal operation. Ditching is a controlled emergency landing on the water su ...

jet trainer
A jet trainer is a jet aircraft for use as a trainer, whether for basic or advanced flight training. Jet trainers are either custom designs or modifications of existing aircraft. With the introduction of military jet-powered aircraft towards the e ...
. 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
