Click here to view a slideshow of images from Ambush's time in Barrow through various stages of her construction from first cut steel in 2001 to her keel laying ceremony two years later to her launch in 2010 when she was lowered into the water for the first time.
Ambush, the most advanced hunter-killer submarine ever produced for the Royal Navy, is at the cutting edge of submarine design and manufacture. She is 97 metres long, weighs 7,400 tonnes and is capable of circumnavigating the globe without the need to surface and limited only by food storage capacity. Able to deploy rapidly, the second Astute class submarine is powered by a nuclear reactor that can run for her 25 year lifespan without refueling.
