At various times, DID has covered advance materials procurement and other contracts under the program to modify some of the USA’s nuclear-powered Ohio Class SSBN nuclear missile submarines to become long range conventional strike and special operations SSGN “Tactical Tridents.”
Four ultra-stealthy Ohio-class SSBNs are having their 24 Trident II D-5 nuclear ballistic missiles removed and replaced with up to 154 Tomahawk cruise missiles. The USA is also adding accommodation for 66-102 special forces troops, special attachments for new Advanced SEAL Delivery System (ASDS) or older Seal Delivery Vehicle (SDV) “mini-subs,” and a mission control center. In future, the SSGNs may also carry UUV underwater robotic vehicles and even UAVs for aerial operations.

We also offer comprehensive coverage of the announced contracts under this $1.4 billion refurbishment and conversion program to date, including a number of related ancillary contracts and programs.
