The T-AS class vessels are submarine tenders designed to repair, re-arm, and resupply the U.S. Navy’s submarine fleet. Military Sealift Command (MSC) operates the two remaining sub-tenders using a hybrid model, with both vessels homeported in Guam, where they spend most of their time. Similar to the T-AH, LCC, and ESB ships, MSC CIVMARs are responsible for the physical maintenance of the ship, while Navy sailors handle many of the mission-specific tasks. MSC assumed control of the Emory S. Land in 2008 and the Frank Cable in 2010. Both ships are aging, and although their service life is nearing its end, the exact retirement dates are not yet known. The Navy has begun the process of procuring the next generation of submarine tenders, with delivery anticipated sometime in the 2030s.
These vessels are known for “homesteading” due to their homeported status. CIVMARs assigned to one of the sub-tenders often extend their rotations, remaining with the vessel for years. This can make it challenging to secure an assignment, depending on your rate.
Additionally, sub-tenders may have heightened security measures because of their close affiliation with submarines. The U.S. Navy is understandably secretive about its submarine fleet.
Overall, these ships are popular among CIVMARs because they are almost always in port and offer good pay. Many CIVMARs, particularly those living in Guam, choose to stay on these vessels for extended periods.
