Ships and Men of the Army Transport Service (ATS)

by Charles Dana Gibson

With the beginning of World War II, the fleet was again expanded. In 1942, the Army Transport Service was absorbed into the Army's Transportation Corps, becoming part of the Water Division, its civilian seamen employees being classified as members of the Water Division's "Civilian Branch."

At peak force during WWII, the Army's owned and bareboat chartered fleet have been enumerated as follows:

Self Propelled Vessels Over 1,000 gross tons and over 200 feet LOA:

35 large troop transports
16 cargo
55 inter-island
2 cable laying
1 news and communication
36 floating, self-propelled warehouse, repair, spare parts, and miscellaneous
23 hospital

With but few exceptions, the large tonnage ships were manned by civilian seamen of the Water Division. Of the large tonnage fleet, 31 vessels were lost to either enemy action or marine casualty.

 

LIBERTY SHIPS IN WWII

During the early years of World War II, enemy mine fields, aerial assaults, and U-Boat attacks seriously crippled the Allied cause by sinking huge numbers of merchant ships carrying equipment, supplies, and troops. In order to build ships faster than the enemy could sink them, President Franklin D. Roosevelt organized an unprecedented emergency shipbuilding program. Between 1941 and 1945 more than 2,700 Liberty ships were produced -- "the cargo carrying key to victory." By the time the program ended in 1945, eighteen shipyards on the Atlantic, Pacific, and Gulf participated in the effort.

Two-thirds of all the cargo that left the United States during the war was transported in Liberty ships. Two hundred of the vessels were sunk, but there were so many at sea that the enemy could not close sea lanes and crucial supply routes.

Mines and Degaussing

Hundreds of ships were sunk or badly damaged from mines planted by planes, minelayers, and submarines in the North Sea, English Channel, and Mediterranean Sea. German submarines also laid mines in the Delaware River, Chesapeake Bay, Boston, Charleston, Jacksonville and New York harbors. The Germans counted on the submarine to win the war at sea, with the mine an important "assist."

The Japanese heavily mined the waters of their homeland and their conquered territories throughout Asia. These mines did not distinguish between ships, nor did they recognize V-E or V-J Day as the end of war.
