Context paragraphs:
Puritan (ACM-16): "Puritan" (ACM-16/MMA-16) was built for the United States Army as U.S. Army Mine Planter (USAMP) "Col. Alfred A. Maybach" MP-13.  The ship was transferred to the United States Navy and classified as an auxiliary minelayer.  "Puritan" was never commissioned and thus never bore the "United States Ship" (USS) prefix showing status as a commissioned ship of the U.S. Navy.

HMS Emperor (D98): USS "Pybus" (CVE-34) was initially a United States Navy "Bogue"-class escort carrier .  The ship was transferred to the United Kingdom for service in the Royal Navy as the Ruler-class escort carrier HMS "Emperor" (D98) as part of the Lend-Lease program of World War II.  Entering service in 1943, the ship took part in operations against the German battleship "Tirpitz" and the invasions of Normandy and southern France.  Returned to the United States following the war, the carrier was sold for scrap in 1946.

United States Ship: United States Ship (abbreviated as USS or U.S.S.) is a ship prefix used to identify a commissioned ship of the United States Navy and applies to a ship only while it is in commission.  Before commissioning, the vessel may be referred to as a "pre-commissioning unit" (PCU), but is officially referred to by name with no prefix.  After decommissioning, it is referred to by name, with no prefix though commonly, people refer to those ships with the prefix Ex-U.S.S. In service but non-commissioned Navy ships go by the prefix USNS, which stands for United States Naval Ship.

Lend-Lease: The Lend-Lease policy, formally titled "An Act to Promote the Defense of the United States", (Pub.L.  77–11 , , 55 Stat.  31 , enacted  11, 1941 ) was a program under which the United States supplied Free France, the United Kingdom, the Republic of China, and later the Soviet Union and other Allied nations with food, oil, and materiel between 1941 and August 1945.  This included warships and warplanes, along with other weaponry.  It was signed into law on March 11, 1941 and ended in September 1945.  In general the aid was free, although some hardware, such as ships, were returned after the war.  In return, the U.S. was given leases on army and naval bases in Allied territory during the war.  Canada operated a similar smaller program under a different name.

New South Wales 79 class locomotive: In 1943, during World War II, four diesel-electric industrial shunting type locomotives built by General Electric Company, Erie for the United States Army Transportation Corps (USATC) were imported from the United States of America by the Department of Supply under Lend-Lease conditions for use at the Dunheved munitions factory in Sydney.  They were four units of 58 units built for the USATC by General Electric numbered 8499-8528 & 7900-7929.

USS Enterprise (CV-6): USS "Enterprise" (CV-6), was the seventh U.S. Navy vessel to bear the name.  Colloquially called "the Big E", she was the sixth aircraft carrier of the United States Navy.  A "Yorktown"-class carrier, she was launched in 1936 and was one of only three American carriers commissioned before World War II to survive the war (the others being "Saratoga" and "Ranger" ).  She participated in more major actions of the war against Japan than any other United States ship.  These actions included the Attack on Pearl Harbor (18 dive bombers of VS-6 were over the harbor, 6 were shot down with a loss of eleven men, making her the only American Aircraft carrier with men at Pearl Harbor during the Attack and the first to receive casualties during the Pacific War), the Battle of Midway, the Battle of the Eastern Solomons, the Battle of the Santa Cruz Islands, various other air-sea engagements during the Guadalcanal Campaign, the Battle of the Philippine Sea, and the Battle of Leyte Gulf.  "Enterprise" earned 20 battle stars, the most for any U.S. warship in World War II, and was the most decorated U.S. ship of World War II, She is also the first American ship to sink an enemy vessel during the Pacific War, the sole surviving pilot of the six planes shot down over Pearl Harbor sank Japanese submarine I-70 on 10 December 1941.  On three occasions during the Pacific War, the Japanese announced that she had been sunk in battle, resulting in her being named "The Grey Ghost".

HMS Willowherb (K283): During the first year and more after America entered the war against the Axis, the United States Navy suffered from an acute shortage of warships, particularly of antisubmarine warfare and escort types.  To fill that need, an extensive ship construction and acquisition program was inaugurated.  Part of that program consisted of placing orders with British and Canadian firms already tooled up to produce Flower-class corvette .  Vitality" (PG-100) was such a ship.  However, before she was launched on 15 April 1943 by the Midland Shipyard in Canada, she was traded to the Royal Navy under the terms of the lend-lease agreement for a similar ship being constructed in Canada.  The British renamed her HMS "Willowherb, and she served in the Royal Navy for the duration of the war.  On 11 June 1946, she was returned to the custody of the United States Navy.  Though carried on the Navy list as PG-100 following the war, "Vitality" never actively served the United States Navy.  She remained idle until sold on 7 May 1947.  To whom she was sold and for what purpose is unknown, but one source indicates that she was not scrapped until 1961.

Persian Gulf Command: The Persian Gulf Command was a United States Army service command established in December 1943 to assure the supply of U.S. lend-lease war material to the Soviet Union.  Its history originated in September 1941, when the U.S. Military Iranian Mission led by Engineer officer COL Raymond A. Wheeler (later CG) was established to facilitate lend-lease supply to the U.S.S.R.  At this same time, the Iranian District of the North Atlantic Division was set up to provide construction support.  In August 1942 the mission was re-designated as the Persian Gulf Service Command, and in December 1943 became the Persian Gulf Command.  It subsequently came under the command of a succession of engineer generals.  Following the War Department’s full militarization of construction, the Iranian District ceased to exist in May 1943.  Three districts directly subordinate to the area command eventually replaced it.  Eventually thousands of personnel worked in Iraq as well.

United States Navy ships: The names of commissioned ships of the United States Navy all start with USS, for "United States Ship".  Non-commissioned, primarily civilian-manned vessels of the U.S. Navy under the Military Sealift Command have names that begin with USNS, standing for "United States Naval Ship".  A letter-based hull classification symbol is used to designate a vessel's type.  The names of ships are selected by the Secretary of the Navy.  The names are those of states, cities, towns, important persons, important locations, famous battles, fish, and ideals.  Usually, different types of ships have names originated from different types of sources.

USS LST-594: USS "LST-594" was an "LST-542"-class tank landing ship , built for the United States Navy during World War II.  The "LST" stands for Landing Ship, Tank, while the "USS" stands for United States Ship.  "LST-594" was part of the second wave of LST's, denoted LST Mk.2's, which began production in 1943, replacing the earlier Mk.1 version.  Within the Mk.2 version, there were three classes: LST-1, LST-491 and LST-542.  The USS "LST-594" was a member of the 542 class, which had several operational and armament upgrades over the prior classes.
