This list includes all US sealift ships, both Navy-owned and chartered. Hospital ships and tankers & freighters serving in a non-combat logistics roles are listed separately, as general logistics ships.
Ships not yet commissioned, or in long-term overhaul/conversion, are listed in italics. All designations & classifications are unofficial; they may or may not correspond to "official" designations. Most ships are listed by MarAd "type" rather than by conventional class names; nation of origin is used where there is no MarAd type. Ships built for or extensively rebuilt for naval service are listed by conventional class names. All ships on this list are assigned to MSC and are civilian-manned. Where two dates are given (i.e. 1965/82), the first is the date of initial completion, and the second is the date of acquisition, conversion, or transfer. Designations given in (parentheses) are assigned but not displayed on the ship's hull.
Status abbreviations are as follows:
ROS: Reduced Operating Status (numeral indicates number of days required for mobilization).
MPF: Marine Prepositioning Force (Marine Corps prepositioning)
CPF: Combat Prepositioning Force (Army prepositioning)
LPS: Logistics Prepositioning Ships (USN field hospital, USAF ammunition, general-use fuels)
RRF: Ready Reserve Force (numeral indicates number of days required for mobilization).
Most prepositioned ships are assigned to one of three Maritime Prepositioning Squadrons (MPSRons) for administrative purposes: MPS-1 in Europe, MPS-2 in the Indian Ocean at Diego Garcia, and MPS-3 in the Western Pacific at Guam and Saipan. Afloat Prepositioning Squadron Four, located at Diego Garcia, has Army Combat Prepositioning Ships assigned.
TEU stands for Twenty-Foot Equivalent Unit, the standard measure of container capacity. One TEU is a 20x8x8 foot standard intermodal container.
Navy-owned ships carry "USNS" prefixes with their names; others have civilian prefixes (M/V, S/S, etc.).
The new-construction/new-conversion prepositioning ships are roll-on/roll-off vehicle cargo ships, with additional container and general-cargo capbility, meant to carry large numbers of Marine Corps or Army vehicles and supplies. Such ships have vehicle unloading ramps and heavy cranes to facilitate self-unloading. In addition to the new/converted ships, a number of unmodified container, RO/RO and LASH ships and tankers are employed to preoposition supplies, munitions and equipment.
Watson
class Army prepositioning ships (8 ships)
Notes: New construction Large Medium Speed Ro/Ro (LMSR) ships for prepositioning of Army vehicles and equipment. All four classes of LMSRs (two conversions, two new-construction) are functionally similar, with four 57 ton cranes, two sideport vehicle ramps, one stern vehicle ramp, and a large helicopter deck.

Notes: One of the original Army LMSR conversions, now further converted to serve as a Marine Corps prepositioning ship. The Marine Prepositioning Force (Enhanced) [MPF(E)] program initially included three prepositioning ship conversions to enhance MPF sealift capacity. This vessel has been substituted for the planned third conversion. Modifications included berthing for 50 additional personnel, helo deck upgraded for night operations, and stern ramp modified for in-water operation (to launch amphibious vehicles).
