As a thought exercise, I wondered what the ships would look like in an end of life configuration:
You can see several major changes:
- Addition of the Mk-110 57mm cannon forward
- Swapping out of the Mk-26 for an 80 cell VLS array
- Updated Comms and radar sets
- New, smaller mast following the removal of SPS-49
- Mk-49 RAM launcher in place of Phalanx
- Active Phased Arrays replacing the SPY-1 faces. This allows for the removal of the SPG-62s, which in turn gave me a place to put the SPQ-9
- Taller hanger to accommodate a single MH-60R Seahawk.
- Newer, more modern ship's craft in the form of RHIBs
I figure they would have been withdrawn in the 2007-2010 timeframe, if they last that long. A thank you to Erik_T for his help with this thought exercise.
