Footage that has been shared online shows two sailors flying over the Harbour in jet packs, before boarding back on a Royal Navy warship.
The pair can be seen hovering over the port, as they head towards Britain’s most powerful vessel in history, reports the Express.
The two servicemen were filmed smiling at one another, before donning a helmet-steered weapon mount and a tactical jet suit.
The Gravity Industries suits use more than 1000php of Jet Engine power, and have been likened to the “real-life Iron Man”.
The showcase was part of the Anglo-American military, political and strategic relations summit at the Atlantic Future Forum (AFF), that was held aboard the HMS Queen Elizabeth.
Speaking to The Express, Chief Test Pilot Richard Browning said: “The team and I are delivering on the vision to build Gravity into a world-class aeronautical engineering business, challenge perceived boundaries in human aviation, and inspire a generation to dare ask ‘what if...’”
Mr Browning, who had previously served in the British Royal Marines, flew a 5-engine jet pack around the British battleship in 2020.
In a press release, reported by Yahoo, Gravity said that the suit is still in the experimental stages, adding that it had been designed to: “provide extremely rapid access to any part of the target vessel, instantly freeing up hands to bear a weapon, and even retaining the capability to relocate on target or self-exfiltrate.”
They added: “This is increasingly seen as a revolution in tactical capability for many special forces and has much broader application beyond Maritime boarding.”
