Ron,

The Columbia Class will have a ducted propulsor (Prop.).

We examined moving the aft control surfaces inboard  on ducted  propulsors years ago.

1. Electric Propulsion-no reduction gears-much quieter
2. X shape stern control surfaces with stern planes inside the housing of the propulsor (water jet) drive system. (No prop)
3. Maneuvering Room area is 3 levels.  Top level is Advanced Seal Delivery System.
4. Retractable bow (sail planes)
5. 6 mast sail vs Ohio's 10.
6. Bow Dome is composite material to better pass signals through
7. Same length as Ohio but 1 foot wider
8. HY100 Stainless hull coated with rubber material
9. New reactor control rod surfaces for better reactor control.
10. 42 year life
11. 2027 should see the first one in the water.  12 to replace current 16 Ohios.  Because of increased reactor core life, less overhauls, thus balancing out the 12/16 ratio. 
12. D-5 Trident II missiles
13. First cost is $6.2 billion then down to $4.2 billion
