LONDON --- The largest uncrewed aircraft ever launched from a Royal Navy aircraft carrier has paved the way for the next generation of UK naval air power.

Codenamed ‘Mojave’, the specially-modified aircraft – operated remotely by a ‘pilot’ at a computer terminal – has taken-off from and safely landed back on board HMS Prince of Wales in a unique trial off the East Coast of the USA.

No crewless machine its size – nine metres long, with a wingspan of 17 metres (six metres wider than an F-35B Lightning stealth fighter) and weighing more than 1½ tonnes fully loaded – has ever flown from an aircraft carrier outside the US Navy before.

The trial off the coast of Virginia further unlocks the potential of the UK’s Queen Elizabeth-class aircraft carriers, demonstrating how modern uncrewed air systems can operate alongside fifth-generation crewed aircraft like the Lightnings.

“The Mojave trial is a European first – the first time that a Remotely Piloted Air System of this size has operated to and from an aircraft carrier outside of the United States,” said Rear Admiral James Parkin, Royal Navy Director Develop, whose team planned the trial.

“The success of this trial heralds a new dawn in how we conduct maritime aviation and is another exciting step in the evolution of the Royal Navy’s carrier strike group into a mixed crewed and uncrewed fighting force.”

The Royal Navy’s Second Sea Lord, Vice Admiral Martin Connell, said embracing autonomy was “the next logical step to ensuring that the Royal Navy can continue to fight and win in an increasingly-complex operating environment”.

He continued: “With so many international partners interested in the results of these Mojave trials on board HMS Prince of Wales, I am delighted that we are taking the lead in such exciting and important work to unlock the longer-term potential of the aircraft carrier and push it deep into the 21st Century as a highly-potent striking capability.”

The Royal Navy has two decades’ experience in operating pilotless aircraft from its ships, but the Fleet Air Arm’s existing systems – such as the hand-launched Puma, and the new Peregrine miniature helicopter which enters service in January – are designed for short-range surveillance operations on land and at sea.

Mojave – a version of the MQ-1C Gray Eagle aircraft adapted for short take-off and landing from runways even shorter than the flight deck of Queen Elizabeth-class carriers – is a much larger and more complex aircraft.

Produced by US company General Atomics, Mojave is capable of performing numerous long endurance missions from medium altitude.

It’s from the same family of aircraft as the Royal Air Force’s new Protector RG Mk1 aircraft, such ‘medium altitude long endurance’ remotely piloted aircraft are capable of conducting long-range surveillance and strike missions over many thousands of square miles.

Months of planning by experts from the Royal Navy, General Atomics and HMS Prince of Wales’ crew went into the trial – one of several involving crewless aircraft and F-35s this autumn to push the boundaries of operations involving the UK’s two carriers.

“My team and I are excited and proud to be the first to launch and land a Mojave from an aircraft carrier,” said Commander Martin Russell, in charge of air operations aboard HMS Prince of Wales.

“During a deployment centred around experimentation and expanding the envelope of the Queen Elizabeth class, this is one of the highlights.

“Integrating the Navy Develop and General Atomics personnel into the Prince of Wales team was key to enabling such a large Remotely Piloted Air System to operate from the deck during this trial, with the capability feeling like a glimpse into the future of these ships.”

HMS Prince of Wales is now conducting intense training and trials activity with the US Marine Corps before returning home to Portsmouth next month.

GA-ASI Demonstrates Short Takeoff/Landing of UAS on UK Carrier

SAN DIEGO --– General Atomics Aeronautical Systems, Inc. (GA-ASI) conducted a first-of-its-kind demonstration of its short takeoff and landing (STOL) capability on the HMS Prince of Wales, a Royal Navy aircraft carrier, using the Mojave Unmanned Aircraft System. The demonstration took place on November 15, 2023, when the Prince of Wales was underway off the East Coast of the U.S., and the Mojave was controlled by an aircrew within a control station onboard the ship. The demonstration included takeoff, circuits, and approaches and ended with a landing back onto the carrier.

“We applaud the Royal Navy’s foresight in embracing this unprecedented capability for its carriers,” said GA-ASI CEO Linden Blue. “We knew our STOL capability would enable a UAS to safely take off and land on the Prince of Wales. Seeing our Mojave operate successfully in this environment opens myriad new ways our aircraft can be used to support multi-domain naval operations.”

Mojave is a short takeoff and landing UAS demonstrator originally developed to prove STOL operations at unprepared landing sites. While Mojave shares common systems and components with GA-ASI’s Gray Eagle model, a STOL wing set option is likewise being planned for the larger, more capable MQ-9B aircraft, which includes SkyGuardian, SeaGuardian, and the new Protector RG Mk 1 currently being delivered to the UK Royal Air Force. The MQ-9B version, called MQ-9B STOL, is being considered by the Royal Navy and other navies that operate aircraft from large flat-deck warships without catapults and arresting gear.

Royal Navy Director Develop, Rear Admiral James Parkin, whose team planned the trial, said: “The Mojave trial is a European first – the first time that a Remotely Piloted Air System of this size has operated to and from an aircraft carrier outside of the United States. The success of this trial heralds a new dawn in how we conduct maritime aviation and is another exciting step in the evolution of the Royal Navy’s Carrier Strike Group into a mixed crewed and uncrewed fighting force.”

Equipping UAS with STOL capability provides greater versatility and allows the aircraft to operate in areas previously deemed unsuitable for UAS operations, including landing onto and taking off from an aircraft carrier. MQ-9B STOL will be capable of carrying the same payloads and conducting the same missions as the SkyGuardian and SeaGuardian, including maritime surveillance, Anti-Submarine Warfare (ASW), Airborne Early Warning (AEW), and surface strike.

General Atomics Aeronautical Systems, Inc. (GA-ASI), an affiliate of General Atomics, is a leading designer and manufacturer of proven, reliable RPA systems, radars, and electro-optic and related mission systems, including the Predator RPA series and the Lynx Multi-mode Radar.
