MYSTERY NAVY LAUNCH

Doing the fatherly thing the other day, walking the dog, I was doing a lap of the Devonport Naval Base (outside of the ’no go’ fence) when I spotted the above launch tucked under a tunnel house. 

Wasn’t sure if it was there slowly decomposing or whether the navy were refitting her.

I suspect the above question will be answered quick smart by Chris Leech and hopefully we might learn more about the craft.
