HMS Queen Elizabeth departed from the Cromarty Firth today to continue sea trials.
Sea trials monitor speed, manoeuvrability, power and propulsion as well as undertaking weapons trials and additional tests on her levels of readiness.
Sea trials were planned beginning in March 2017 but minor technical issues delayed her sea trials until the end of June. Prior to the ship’s departure from Rosyth, an extensive survey was carried out of the Firth of Forth by HMS Gleaner and 42 Regiment, Royal Engineers to gather information on the tides, the depth of the river bed, and the height of the three river crossings (Forth Bridge, Forth Road Bridge, Queensferry Crossing). This was necessary as the most recent data available was 60 years old.
HMS Queen Elizabeth had her first stopover at Invergordon, where the ship was fuelled and provisioned, and where inspections of the hull were carried out.
Following this initial period, HMS Queen Elizabeth will return to Rosyth for further testing and maintenance before heading back to sea for a second stage which aims to test her Mission Systems. She will transit to her home port of Portsmouth Naval Base to be handed over to the Royal Navy later this year.
