From Mitchum's plan, I'd move a thruster to Hastings (4 turns), Orleans (4 turns with terraforming -- workers enroute), and Bahamas (5 turns). Hastings and Orleans will each need 3 more workshops to hit this number -- should be doable with the workers running around. We can move some of the workers near Canterbury up to Hastings to make the necessary workshops there. Orleans has 4 around it already which can make the requisite workshops.
Nottingham can do a thruster in 5 (no worker turns needed) and Life Support can move to Oxford (5). I think this will help free up more gold on T244.
Also, note that York does NOT have an RSI. So it can't build SS parts. And we shouldn't use Chengdu to build parts because it can revolt
Which it did once during my set.
