Hybrid MSC/Navy vessels designed to repair, re-arm, and resupply the U.S. Navy's submarine fleet. Homeported in Guam, these floating repair shops are popular for their in-port lifestyle and high pay.
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.
These vessels are known for "homesteading" due to their homeported status. CIVMARs often extend their rotations, remaining with the vessel for years.
Extended rotations can make it challenging to secure an assignment, depending on your rate.
Many CIVMARs, particularly those living in Guam, choose to stay on these vessels for extended periods.
Sub-tenders may have heightened security measures because of their close affiliation with submarines. The Navy is understandably secretive about its submarine fleet.
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 procuring the next generation of submarine tenders, with delivery anticipated sometime in the 2030s.
The AS vessels are old, hybrid ships. As a result, their layout can be confusing, and it may take some extra time to learn the layout of the ship.
These ships do not have personnel elevators, and the ladders/stairwells are very steep
Old hybrid design means the layout can be confusing for new crew
Unlike every other ship in the fleet, these ships DO have WiFi
Hybrid Model: MSC CIVMARs handle physical maintenance of the ship, while Navy sailors handle mission-specific tasks related to submarine support.
Overall, these ships are popular among CIVMARs because they are almost always in port and offer good pay.
