Barrow-in-Furness and AUKUS: new R&D facility (Project SPARTAN) to go up in blue circle area; dark red was planned location of RAMSDEN hall proposal, since abandoned. The red square is land BAE acquired for the new hull cross-sections manufacture facility that succeeds RAMSDEN.
The new facilities to go up are expected to be significantly larger than RAMSDEN hall was. Hull sections built here are reportedly going to reach the Devonshire hall by barge, over the water. Hull sections containing the reactor will be built here for the Australian SSNs too.
The RAMSDEN hall (images 1 and 2) was going to be 66m wide by 175 long, with height approximately 45 m. The new facility is probably going to look quite different and might be even larger overall. ABP has offered a (very notional, non BAE-Systems made) notional image (3rd image).
Reactor integration work is carried out in buildings D58 and D59 behind Devonshire Dock Hall. These are brand new and i assume will of course handle SSN-Aukus work too. So australian submarine sections are likely to pass through the entire site before being shipped down south.
