 While serving with the War Plans Section of the Bureau of Navigation in Washington, D.C. between the World Wars, developed an interest in amphibious warfare.
 In 1940 he produced "Fleet Training Publication 167 – Landing Operations Doctrine, United States Navy", which would become the Navy's "bible" of amphibious operations, and would remain in use throughout World War II.

 A 1911 graduate of the United States Naval Academy, he served on submarines during World War I.

The North American Aviation T-6 Texan is an American single-engined advanced trainer aircraft used to train pilots of the United States Army Air Forces (USAAF), United States Navy, Royal Air Force, and other air forces of the British Commonwealth during World War II and into the 1970s.
 Designed by North American Aviation, the T-6 is known by a variety of designations depending on the model and operating air force.
 The United States Army Air Corps (USAAC) and USAAF designated it as the AT-6, the United States Navy the SNJ, and British Commonwealth air forces the Harvard, the name by which it is best known outside of the US.
 Starting in 1948, the new United States Air Force (USAF) designated it the T-6, with the USN following in 1962.
 It remains a popular warbird aircraft used for airshow demonstrations and static displays.
 It has also been used many times to simulate various Japanese aircraft, including the Mitsubishi A6M Zero in movies depicting World War II in the Pacific.
The "Gato"-class were a class of submarines built for the United States Navy and launched in 1941–1943; they were the first mass-production U.S. submarine class of World War II.
 Together with their near-sisters the "Balao" and "Tench" class es, their design formed the majority of the United States Navy's World War II submarine fleet.
 Named after the lead ship of the class, USS "Gato" , the "Gato"s and their successors formed the core of the submarine service that was largely responsible for the destruction of the Japanese merchant marine and a large portion of the Imperial Japanese Navy in World War II.
 "Gato"' s name comes from a species of small catshark.
 Like most other U.S. Navy submarines of the period, boats of the "Gato" class were given the names of marine creatures.
 In some references, the "Gato"s are combined with their successors, especially the "Balao" class.
William Patrick "Willy" Stuart-Houston ("né" Hitler; 12 March 1911 – 14 July 1987) was a British nephew of Adolf Hitler who worked in Germany and later emigrated to America in 1939.
 Born to Adolf's brother, Alois Hitler, Jr. and his first wife, Bridget Dowling, in Liverpool, England, William Hitler later moved to Germany, but subsequently emigrated to the United States, where he served in the United States Navy in World War II.
The T1 tanker or T1 are a class of sea worthy small tanker ships used to transport fuel oil before and during World War II, Korean War and Vietnam War.
 The T1 tanker classification is still in use today.
 T1 tankers are about 200 to 250 feet in length and are able to sustain a top speed of about 12 knots.
 The hull designation "AO" is used by the US Navy to denote the ship is a T1 oil tanker and "AOG" that the T1 is a gasoline tanker.
 The small size allows the T1 to enter just about any sea port or to anchor around a small island, this was very useful during the Pacific War.
 The T1 tanker can carry about 48,000 to 280,000 BBLs.
 Some T1 tankers were used to transport goods other than oil, a few were used for black oil-crude oil, diesel, chemicals and rarely bulk cargo like grain.
 T1 tankers are also called liquid cargo carriers.
 The T1 tanker has about a 6,000 to 35,000 DWT of cargo.
 The small size also gives the ships short turn around time for repair, cleaning, loading and unloading.
 A T1 tanker carrying dirty cargo, like crude oil needs a few weeks of labor to clean before carrying clean cargo.
 Most T1 ships during World War II were named after major oil fields. T1 tanker are operated by the US Navy, War Shipping Administration and United States Maritime Commission.
 Some T1 were loaned to England in the Lend-Lease program for World War II, after the war most were returned to the USA.
 After World War II many of the T1 ships were sold to for civilian use.
 Each T1 had emergency life rafts on the boat deck.
 The ships had cargo booms and piping to load and unload fuel.
 During war time the T1 are armed for protection with deck guns.
 A typical ship may have one single 3"/50 dual purpose gun, two 40 mm guns and three single Oerlikon 20 mm cannon.
 A T1 at war time normally had a crew of 38 and up to 130.
 If operating as a United States Merchant Marine ship, the crew would be a mix of civilian Merchant Marines and United States Navy Armed Guards to man the guns.
Bridget Elizabeth Hitler, née Dowling (alternative Brigid) (3 July 1891 – 18 November 1969), was Adolf Hitler's sister-in-law via her marriage to Alois Hitler, Jr..
 She was the mother of Alois Hitler's son William Patrick Hitler.
 She was born and raised in Dublin, Ireland.
When the United States entered World War II at the end of 1941, the United States Navy found itself deficient in ocean escort-type vessels.
 A crash building program was instituted; but, to meet more immediate needs, the government contracted with shipbuilding firms in England and Canada to build Flower-class corvette .
 Vim" (PG-99) was one of those British-type escorts.
 She was launched on 1 April 1943 at the Collingwood Shipyard in Collingwood, Ontario.
 Nine days later, however, she was transferred to the Royal Navy under the terms of the lend-lease agreement in return for another Flower-class corvette then under construction in Canada.
 The British renamed her HMS "Statice, and she served the Royal Navy under the name through World War II.
 On 21 June 1946, she was returned to the United States Navy.
 Though carried on the Navy list as PG-99, the corvette never saw active service with the United States Navy.
 She was sold on 7 May 1947.
 To whom she was sold and to what purpose she was put is unknown.
The "Tacoma" class of patrol frigates served in the United States Navy during World War II and the Korean War.
 The class is named for its lead ship,  , a S2-S2-AQ1 design, which in turn was named for the city of Tacoma, Washington.
 Ships of the class also served in the British Royal Navy – in which they were known as Colony-class frigates – and the Soviet Navy during World War II.
 "Tacoma"-class ships served in the United States Coast Guard and various navies post-World War II.
SS "Red Oak Victory" is a U.S. military Victory ship of the "Boulder Victory"-class cargo ship used in the Second World War.
 She was preserved to serve as a museum ship in Richmond, California, and is part of the Rosie the Riveter/World War II Home Front National Historical Park.
 She was one of 534 Victories built during World War II, but one of only a few of these ships to be transferred from the Merchant Marine to the United States Navy.
 She was named after Red Oak, Iowa, which suffered a disproportionate number of casualties in early World War II battles.
 (Montgomery County ranked third among Iowa counties in World War II casualties per capita).
 The ship was active during World War II, the Korean War, and the Vietnam War.
