Once the home of the Fleet Air Arm, Daedalus played a pivotal role in British naval aviation. It housed the Royal Navy’s air engineering school and was the busiest airfield in the country on D-Day—an essential launch point during one of the most significant military operations in history. Today, it stands as one of the 20 most important historic aviation sites in the UK, rich with character and layered with visible evidence of past innovation, invention, and service. From its original hangars and control towers to the stories embedded in its runways, Daedalus tells a powerful story of technological progress and national contribution.

HMS Daedalus has stood at the forefront of British naval aviation for over a century. Established in 1917, it became the central air station for the Royal Naval Air Service and later the Fleet Air Arm. Throughout both World Wars and the Cold War, Daedalus was a place of innovation, training, and service - home to naval pilots, engineers, and ground crews who shaped the future of air power at sea.
From early seaplane operations and D-Day flight coordination to Cold War hovercraft trials, Daedalus has supported generations of Royal Navy personnel. Its runways, hangars, and workshops tell stories of courage, invention, and national service.
Today, the legacy of HMS Daedalus lives on in the site’s architecture, atmosphere, and ongoing transformation, honouring the people who served here, and the vital role this place played in Britain’s naval history.
Daedalus has long been a site of aviation and maritime innovation, and the story of the hovercraft is one of its most distinctive chapters. In the 1960s, HMS Daedalus became home to the Interservice Hovercraft Trials Unit (IHTU), a pioneering collaboration between the Royal Navy, Army, and Royal Air Force. This unit was tasked with testing, developing, and trialling hovercraft for military and humanitarian use, exploring their potential across a variety of terrains and operations.
With its coastal location, long runways, and history of experimental aviation, Daedalus was the perfect setting for naval innovation. Throughout the 1960s and '70s, engineers and service personnel worked on-site to push the boundaries of this new mode of transport, contributing to the global advancement of hovercraft technology.
Many of the craft developed or tested at Daedalus are now preserved at the Hovercraft Museum, located on the historic site itself. It holds the world’s largest collection of hovercraft and several of the museum’s craft are listed on the National Historic Ships Register, recognising their importance to British maritime and engineering history.
Today, the legacy of hovercraft innovation lives on through the museum and its passionate volunteers, keeping alive a story that began right here, where land, sea, and air meet.
In the early decades of naval aviation, seaplanes played a crucial role, and Daedalus was one of the few sites in the country purpose-built to support them. With direct access to the Solent, the base became an important training ground and operational centre for waterborne aircraft from the 1920s through WWII.
Slipways and hangars in what is now Seaplane Square supported aircraft maintenance, launch, and recovery, with crews trained in the demanding techniques of maritime aviation. Aircraft such as the Supermarine Walrus and other amphibious models flew reconnaissance, rescue, and patrol missions from the site.
While the age of the seaplane has passed, its legacy remains visible in the layout and surviving structures of the original station, quiet reminders of a time when HMS Daedalus helped shape the future of flight from sea to sky.

Less well known but no less significant is the role HMS Daedalus played in the development and handling of naval torpedoes. During the mid-20th century, dedicated facilities on-site supported the testing, maintenance, and training associated with airborne torpedoes used by the Fleet Air Arm.
Aircraft operating from Daedalus were equipped to carry and deploy torpedoes in anti-ship and anti-submarine missions, a vital part of post-war naval strategy. Technicians and armourers based at the station were responsible for preparing these complex weapons, working to exacting safety and performance standards in specialised workshops.
This quieter side of Daedalus’s operational history highlights the breadth of technical expertise that once defined the site, not just in flight, but in the engineering and logistics behind every mission. Though the torpedo facilities are no longer in use, they form part of the layered military history that makes Daedalus unique.
