That same article was in the Kitsap (Bremerton, WA) Sun a week or two ago. 4 boats, the first 4 Tridents were converted. The Ohio SSBN 726, Michigan SSB 727, Flordia SSBN 728 and Georgia SSBN 728. Ohio and I believe Michigan were converted at Puget Sound Naval Shipyard and Florida and Georgia at Norfolk Naval Shipyard.
