I have been working on new ship lines for all the nations except Russia the is just so little to work with that wouldn't be total fiction. What I have so far is new CV lines for usn and uk.

The new line for USN wou start with CV1 USS Langley at level 54, The first US cv ever made fought in ww2 and was sunk.

The CV2 Would be USS Wolverine, it was a training CV
built on a paddle wheel steamer and operated on the great lakes during WW2. It would be made available at 63.

   The CV3 would be USS Wasp available at 71 it was a modified   
Yorktown that also served during WW2.

    the new CV4 would be the USS Ranger which was the first purpose built carrier constructed by the USN and it would be available at level 82
The line would then merge into the other to get to CV5 

   

 The Uk will get a new CV line as well with the Argus at 55  the Argus was like the Langly the first CV of its nations navy it served all through the war and was scrapped after the war.
the CV2 is the Hermes and it would be available at 66 It also served in WW2 and was sunk by the Japanese in the indian ocean.

    the CV3 would be the Eagle available at level 72
it was another UK cv that served in WW2 and was torpedoed in the atlantic  by a german submarine. This line would then merge into the other CV line as I have yet been able to
have found a suitably unique enough CV4

I have also worked out new BB lines for IJN KM and MN. The IJN are partially real ships and designs, The KM are WW1 battle ships and the MN ships are all designs, They go from
BB1 through BB4 I will post my ideas and hitpoints aircraft space and guns if this is recieved well among the community
