The nuclear-armed ballistic missile submarines are being constructed by BAE Systems at its Barrow-in-Furness shipyard.
The move occurred on 21 September but given the highly sensitive nature of the programme, the MOD have only today (Oct 19) cleared the pictures.
A BAE Systems spokesperson comments: “The longest ever ‘mega-unit’ so far for Dreadnought Boat 1 has been moved down the road into BAE Systems Submarines’ Devonshire Dock Hall (DDH) in Barrow-in-Furness.
“At more than 20m, it was the longest submarine unit to move by road since the fore-end mega-unit moved to the DDH for the final Vanguard boat in the mid-1990s.
“This mega-unit will now take its place on the Dreadnought build line as we continue construction of the next generation of deterrent submarine. Three of the four Dreadnought submarines are currently under construction in Barrow and will deploy into the Royal Navy fleet in the early 2030s.
“BAE Systems’ site on the edge of the Lake District is the home of UK submarine building.”
The Royal Navy add: “All will be assembled under cover in the dock hall – 260 metres long, 58 wide and 51 high, making it almost large enough to accommodate the Titanic – where the final two Astute-class submarines, HMS Agamemnon and Agincourt, are in the later stages of construction/completion, and where the ‘mega unit’ will take its place on the Dreadnought build line.
HMS Dreadnought is due to enter service in the early 2030s.
