Didn't they retrofit some of the Ohio classes to remove their launch tubes and use them as SOF (i.e., SEAL) insertion platforms?
I can't think of any reason why they would need a Trident-equipped boat anywhere near the Med. With the 8,000 mile range of those puppies, you could bullseye anyplace in Russia from the IO, Pacific or Atlantic.
Launch tubes can't be removed as they are part of the pressure hull. Normally, concrete billets are inserted to equal missile weight and preserve buoyancy characteristics. It has been suggested that slide-in gear "trays" might be used by SEALs in 1-2 tubes as required.
The ASDS SEAL delivery system program is essentially defunct after much ballyhoo in the early 2000s. Variety of reasons, but massive cost over-runs never help. The four SSGN Ohio conversions were slated to carry the ASDS, and SEAL berthing and support gear was installed I believe. The USS Jimmy Carter, one of the three Seawolf boats, was also designed to be a special operations support platform. Any of the Virginia class can carry a limited number of SEALs and put them ashore, same as the 688s could.
As for SSBNs, in the later Polaris and through the Poseidon eras, we had a base at Rota, Spain that deployed a squadron into the Med. They were covering the Black Sea area, some of central Asia, some of Eastern Europe--swing an arc and it's easy to see where they aimed. We closed the base in the late 70s or so when ranges grew with the C-4 Trident, and then later the D-5. While it was open it was sweet, sweet duty. Lots of guys re-upped to get a tender billet there.
