For those who don't know, submarines at the BAE yard in Barrow are built in slices and the slices are then carried through the streets on special transporters to be put together, like a Swiss roll in reverse, in the huge Devonshire Dock Hall.
And this, three storeys high and wrapped in protective material, is the final part of the seventh and last boat in the Astute class of nuclear-powered submarines, to be called Agincourt, being taken to assembly.
There is a fair amount of work to do yet before this vessel goes into service. HMS Agincourt, as she will become, will head out to sea in the 2020s.
Three female engineers at the Barrow shipyard are hoping to inspire Girl Guides in the far east that engineering isn't just a career for boys.

The engineers want to pass on their enthusiasm and change perceptions about the industry.
Defence Secretary Gavin Williamson has said the third Dreadnought submarine will be called Warspite, a name used by eight previous warships including one built in the reign of Queen Elizabeth I.

Warspite, which is still on the drawing board, will be the third of the class, joining Dreadnought and Valiant which will be the first new boats to carry Britain's nuclear missiles.
