London, England (CNN) -- The British nuclear submarine that got stuck on the Scottish coast is free, the Defence Ministry told CNN Friday.
The HMS Astute, which ran aground off the Isle of Skye, was pulled free as the tide came in Friday afternoon.
"She will now be tugged out to deeper water," the ministry said. There have been no injuries and the submarine remained watertight.
"This is a not a nuclear incident. There is no indication of any environmental impact," the ministry said in an earlier statement.
The Astute is called the United Kingdom's most powerful attack submarine. It was commissioned in August.
The craft is a "highly complex feat of naval engineering" that is "at the very cutting edge of technology, with a suite of sensors and weapons required to pack a powerful punch," the ministry said.
The submarine was undertaking sea trials when it ran aground. People were transported out of the craft.
The ministry said the sub can carry a mix of up to 38 Spearfish heavyweight torpedoes and Tomahawk land-attack cruise missiles.
