dreadnought

The new Dreadnought boats being built at Barrow-in-Furness to replace the current submarines in the early 2030s carry an estimated cost of £31bn.

In plane sight: "A A400m Callsign Dreadnought 60 doing a fly through at Oban Airport," says Murray MacGregor.

The site in Govan will build the integrated optronic combat system mast, the above water "eyes", for the future nuclear deterrent class Dreadnought.

It is already on contract to build the ultra-powerful Sonar 2076 system for the Dreadnought class which now means it will be providing the boat's "eyes and ears" behind the platform's operational capability.

The Dreadnought version continues the tradition and the wider programme, from design through to build, will sustain around 30,000 jobs across the UK.
