Army

Under the Army organization of 1940, the Army Quartermaster was charged with the responsibility of providing the Army with all water transport services except those specifically authorized; for the Corps of Engineers in rivers and harbor work, for the Coast Artillery in mine planting, and for the Signal Corps in cable laying or communications vessels. In March 1942, most of the transportation functions of the Army Quartermaster were consolidated into the Transportation Division of the newly created Services of Supply. That same year, on July 31, the Transportation Corps was established.

Coast Artillery Corps Mine Planter Service

The Army Mine Planter Service was responsible for the mine fields of the coast defenses. The largest vessels of the service wes the U.S. Army Mine Planter (USAMP) equipped to install both the mines and associated control cables. Smaller vessels known as, "junior mine planters", or "pup planters", were occasionally employed as mine planters, but for the most part they served as freight and passenger boats for river and harbor duty. In addition to the mine planters, the Coast Artillery vessels include distribution box boats used for servicing cable distribution boxes in the mine fields and motor mine yawls, which are rugged utility boats.

SMALL BOAT COMPANY

The small boat company is organized for the purpose of hauling cargo and passengers to bases along the coasts or to nearby islands within the theater.

HARBOR CRAFT COMPANY

The harbor craft company is organized for the purpose of ferrying to shore cargo from freighters and transports arriving in theaters of operation. The vessels may either be riding offshore at anchor in the open sea or more likely, anchored in a harbor. Cargo from the ships is loaded by Transportation Corps port company personnel onto barges. Then tugs, tow boats, or marine tractors propel the barges to the shore for unloading. Any cargo too heavy for the vessel's gear to lift is handled by a 60-ton floating crane.

Port & Harbor Rehabilitation

Port Construction and Repair Group

The primary mission of the engineer port construction and repair group is to make ready for use the facilities of ports of debarkation in a theater of operations. and to perform work involved in improvement or expansion of such ports, exclusive of harbors. Its work is performed in conjunction with engineer port repair ship operations offshore.
The construction platoon consists of a divers' section under the supervision of an officer, as master diver. Enlisted personnel consists of marine divers and divers' attendants. This section does underwater work incident to construction of quay walls, wharves, piers, etc.

Engineer Port Repair ship

The engineer port repair ship is an engineer unit with personnel and equipment to maintain channels and ship berths by removing sunken ships and other obstructions, and to maintain channel markings and other aids for pilots. It also does needed work on docks and wharves in conjunction with engineer port construction and repair groups.
Personnel of this unit operate from a specially equipped ship with repair facilities that include a heavy crane and a machine shop.

Surface combatant type

Surface combatants are ships which are designed primarily to engage enemy forces on the high seas. The primary surface combatants are battleships, cruisers and destroyers. Battleships are very heavily armed and armored; cruisers moderately so; destroyers and smaller warships, less so.

  • ACR: Armored Cruiser (pre-1920)
  • C: Cruiser (pre-1920 Protected Cruisers and Peace Cruisers)
  • CA: (first series) Cruiser (retired, composed all surviving pre-1920 Protected and Peace Cruisers)

The DL category was established in 1951 with the abolition of the CLK category. CLK 1 became DL 1 and DD 927–930 became DL 2–5. By the mid-1950s the term Destroyer Leader had been dropped in favor of Frigate. Most DLGs and DLGNs were reclassified as CGs and CGNs, 30 June 1975. However, DLG 6–15 became DDG 37–46. The old DLs were already gone by that time.
  • DM: Destroyer Minelayer (retired)
  • DMS: Destroyer Minesweeper (retired)
  • FF: Frigate (retired)
  • FFG: Guided Missile Frigate
  • FFL: Light Frigate

  • FFT: Frigate (Reserve Training) (retired)
The FF, FFG, and FFR designations were established 30 June 1975 as new type symbols for ex-DEs, DEGs, and DERs. The first new-build ships to carry the FF/FFG designation were the Oliver Hazard Perry (FFG-7) class frigates. A new series of frigate-size warships for shallow-water combat at expense of battlegroup performance is under production:
  • M: Monitor (1880s–1920)

  • PBR: Patrol Boat, River, Brown Water Navy (Pibber or PBR-Vietnam)
  • PC: Coastal Patrol, originally Sub Chaser

  • PACV: Patrol, Air Cushion Craft, Brown Water Navy (Vietnam)

Amphibious warfare type

Amphibious warfare vessels include all ships having organic capability for amphibious warfare and which have characteristics enabling long duration operations on the high seas. There are two classifications of craft: amphibious warfare ships which are built to cross oceans, and landing craft, which are designed to take troops from ship to shore in an invasion. Some vessels called “landing ships” did not have the capability to off-load troops and supplies onto beaches; they were just transports or command-and-control vessels.
