RRS Sir David Attenborough polar ship ready for launch
Britain's new polar research ship is ready to go in the water.
The newly assembled hull of the RRS Sir David Attenborough is now standing on the slipway of the Cammell Laird yard in Birkenhead, awaiting launch day.
Weather and tide permitting, she should slide into the River Mersey on Saturday.
The £200m vessel will replace the James Clark Ross and the Shackleton, which between them have almost 50 years' service in support of UK polar science.
The company will have an invited audience in the yard on Saturday of more than 2,000 people, made up of VIPs, staff and their families. But star of the day will, of course, be Sir David himself.
The BBC naturalist will be asked to press the button that unleashes his namesake on its grand slide into the water.
The event will be live-streamed by the British Antarctic Survey. Click here to watch.
