HMS Queen Elizabeth returns to port after leak. Credits: MOD (Crown Copyright) The 65,000-tonne future flagship will spend the next month conducting further sea trials, which will include testing with rotary wing aircraft, learning about their behaviour flying to and from the ship in a range of conditions. Commanding Officer of HMS Queen Elizabeth, Captain Jerry Kyd, said: After the excitement of our commissioning ceremony in December, my ships company and our industry partners are looking forward to taking the ship to sea to conduct First of Class Rotary Wing Flying Trials. The Queen Elizabeth Class Carriers are the biggest warships ever built for the Royal Navy – four acres of sovereign territory, deployable across the globe to serve the United Kingdom on operations for 50 years. HMS Queen Elizabeth and HMS Prince of Wales will be the most advanced warships in the Royal Navy fleet. They are the future flagships of the nation. Initially the ships will carry helicopters. The vast flight deck and hangar can accommodate any helicopter in Britains military inventory. From 2020, however, our punch will be delivered by the F35 Lightning II, the worlds most advanced stealth fighter-bomber.
