Courageous-class Large Light Cruisers
HMS Courageous,Glorious and Furious Laid down as real LLC after the cabinet got word of silly plans to build things with 15inch guns.
8 x 9.2 guns
14 x 5.5 guns
These ships didn't do much late in WW1 but they then contributed greatly to problems to the WNT negotiations, GB was not willing to get rid of such new and useful ships but nether was it willing to count them as real capital ships.
I have tried to sim them, (does anybody know how to spoiler the spring sharp hidden so not to take up to much room with blocks of text ?)
It makes them a bit slower than the real LLC but they are the same size/power so should be 31.5 Kn also upped the belt etc to invincible class BCs.
OLD SIM (added 1 more main gun etc.)
