In the aftermath of arms control treaties, some of the USA’s nuclear-powered Ohio Class SSBN nuclear missile submarines are being converted 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.
