Royal Marines can be seen doing exactly that in the video.</p><p>The jet suit is still experimental, but the vision "is 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," Gravity Industries said in its press release.</p><p>In the video, one Royal Marine can be seen immediately disconnecting the arm-mounted jets and pulling out a ladder. After the ladder is secured, he pulls out what appears to be a handgun.</p><p>"This is increasingly seen as a revolution in tactical capability for many special forces and has much broader application beyond Maritime boarding," the company added.</p><p>The new video from Gravity Industries is not the first time that people in jet suits have been seen flying around British ships. Last May, for instance, Gravity released a video of an operator flew from a fast boat onto a Royal Navy P2000 Patrol Boat during what the company called "assault trials."</p><div><iframe width="560" height="315" src="//www.youtube.com/embed/H4FUBfp9kS0" frameborder="0" allowfullscreen></iframe></div><p>And about a week before that video came out, Gravity released another video showing someone wearing a jet suit flying around the British aircraft carrier HMS Queen Elizabeth and practicing intercepting civilian vessels sailing nearby.</p><div><iframe width="560" height="315" src="//www.youtube.com/embed/SoFlqIaDJ8U" frameborder="0" allowfullscreen></iframe></div><p>The new video from Gravity comes just a few weeks after the company released footage from a maritime boarding training exercise with the Netherlands Maritime Special Operations Force.</p><div><iframe width="560" height="315" src="//www.youtube.com/embed/M2KvlQKdBo8" frameborder="0" allowfullscreen></iframe></div><p>Outside of the armed forces, <a href="https://www.bbc.com/news/uk-england-54331994">paramedics with Britain's Great North Air Ambulance Service have looked into using jet suits for remote rescue operations</a>, as the suits allow medical personnel to reach someone in distress in a hard to reach area much faster than they might otherwise be able to by some other means.</p><div><iframe width="560" height="315" src="//www.youtube.com/embed/gtvCnZqZnxc" frameborder="0" allowfullscreen></iframe></div><p>Gravity's jet suit set the record for the fastest speed in a body-controlled jet-engine-powered suit, <a href="https://www.guinnessworldrecords.com/news/2019/11/real-life-iron-man-smashes-his-jet-powered-suit-record-by-flying-at-85-mph">according to Guinness World Records</a>.</p><p>The record was set by British inventor and Gravity founder Richard Browning, who flew over 85 mph during a test flight in 2019.</p><p><a href="https://www.businessinsider.com/video-royal-marines-board-ship-at-sea-with-jet-packs-2021-5#comments">Join the conversation about this story »</a></p> <p>NOW WATCH: <a href="https://www.businessinsider.com/supermarinovation-x2-sport-device-makes-you-human-torpedo-2017-7">This underwater jetpack lets you swim like Michael Phelps</a></p> Click here to read full news..
