On a practical level The Maritime Commission and the WSA worked closely together under the administration of Vice Admiral Emory S. Land at the head of each. Land described this relationship in his report to The President of WSA's progress through December 31, 1943: Under the
Merchant Marine Act of 1936, the United States Maritime Commission was established as an independent agency to direct and control all phases of overseas shipping and shipbuilding. It became apparent immediately when this Nation entered the war that a special agency to deal with the operational problems peculiar to war was necessary to supplement the Maritime Commission. That need brought about the creation of the War Shipping Administration on February 7, 1942, which took over from the Maritime Commission virtually all of the Commission's major statutory functions with the exception of shipbuilding. Thus WSA became the Government's ship operating agency and the Maritime Commission its shipbuilding agency. The WSA authority was extensive. In the same report to the President, Land describes the responsibility: The responsibility of the WSA under the Executive Order of February 7, 1942, extended to all phases of shipping including the purchase or requisition of vessels for its own use or the use of the Army, Navy, or other Government agencies; the repairing, arming, and degaussing of WSA controlled vessels and Allied vessels under
lend-lease provision; conversion of vessels to troop transports, hospital ships, and for other special purposes; training and providing ship personnel, operating, loading, discharging and general control of the movement of these ships; administering and marine and war risk insurance laws and funds, and the control of terminal and port facilities, forwarding and related matters. Under that authority cargo hulls were allocated to either commerce, Army or Navy. Many of the Army's ships and Naval transports were allocated by WSA. WSA, through its agents, directly operated ships in support of the services and civilian requirements. Among the more notable WSA operated ships were large and fast troop transports able to sail largely without escort with WSA operated
Argentina,
Brazil,
John Ericsson,
Lurline,
Mariposa,
Monterey, and
Uruguay being among those ships. In addition, the WSA worked closely with the British
Ministry of War Transport through the Combined Shipping Adjustment Board in ensuring most efficient use of available ship hulls and cargo carrying capacity. Under the "loading, discharging and general control of the movement of these ships" WSA developed and enforced improved methods of utilizing ship capacity and avoiding inefficient use of ships by commerce and the military services. ==Postwar==
