Over the course of the 1990s and the 2000s, the navy has begun a series of projects to improve its fleet, with a view to providing enhanced capabilities, although many of these have been cut or cancelled.

 F-35B. This will tie in with the decision to build HMS Queen Elizabeth in a CATOBAR configuration. However, it will also mean that the Fleet Air Arm will not operate fixed wing aircraft at sea for up to ten years.
The anti-surface/anti-submarine mission remains the purview of rotary aircraft; in small ships this is the updated Mk8 version of the Lynx. The Future Lynx program has seen 28 of the new helicopters, baptized the AW159 Wildcat Lynx, ordered for the Royal Navy. However, in the carriers and in later frigates, the larger Merlin helicopter is used - this has replaced the Sea King in the ASW mission. There are 44 Merlin helicopters in service, and an upgrade plan to increase their flexibility of use is planned. The Sea King HC4 remains in the commando assault mission from HMS Ocean

. In late 2009 it was announced that the Fleet Air Arm would lose its remaining Sea King helicopters, their place being taken by Merlins transferred from the RAF.

Merlin is also being touted as a replacement for Sea King ASaC7 in the Maritime Airborne Surveillance and Control (formerly Airborne Early Warning) mission, carrying the same Cerberus radar suite. However, the limitations of using a helicopter in this role are well documented - endurance is limited, service ceiling is low and vibrations from the rotors may cause distortion. Therefore, two other concepts have been put forward: a MASC version of the V-22 Osprey

 aspects of a helicopter with the endurance of a fixed wing aircraft. The E-2 is already in service with the French and US Navies. It has advantages over the V-22 again in terms of endurance and ceiling; because its cabin is pressurised, it can operate at greater altitude than the Merlin, extending the range of its radar.
