Excellent machinery, storage, compartmentation space
Excellent accommodation and workspace room
Good seaboat, rides out heavy weather easily
Cost can be reduced by £4.5M due to reused turrets (- refurbishment costs) + any reused armour from R's.
The ship is declared at 35kt standard due to not including all the ammunition and miscellaneous weight (not going to include the radar in 1937 public plans are we
).
