Camp Grohn was a military base of the U.S. Army on the outskirts of Bremen, Germany after the end of World War II from 1945 to 1954.
 Camp Grohn was originally built in 1936 as "Flak Kaserne" and housed the first battalion of the Luftwaffe's 26th Anti-Aircraft Artillery Regiment prior to the outbreak of World War II.
 Following the defeat of Germany in the war, the U.S. Army took over the military base and renamed it Camp Grohn after the part of Bremen in which the camp was located.
 Camp Grohn was in a small, joint American/British sector in northern Germany called the "Bremen Enclave", which included the ports of Bremen and Bremerhaven.
Pueblo Depot Activity "(PUDA)", formerly known as the Pueblo Ordnance Depot and the Pueblo Army Depot, was a U.S. Army ammunition storage and supply facility.
 Responsibility for the depot fell upon the U.S. Army Ordnance Corps, and the first civilians were hired in 1942 as operations began.
 The mission quickly expanded to include general supplies as well.
 It is a 24202 acre site located 14 mi east of Pueblo, Colorado.
 In 1945 they began to receive mass amounts of equipment returning from the combat theaters of World War II.
 Therefore, the mission expanded yet again to include the maintenance and refurbishing of artillery, fire control, and optical material.
 In 1951 the depot assumed responsibility to distribute U.S. Air Force ammunition for an eight-state area, as well as storage of strategic and critical materials for the General Services Administration (GSA).
 They were also tasked to rebuild and provide on-site maintenance support for guided missiles, ensure calibration and maintenance of electronic test equipment and radio-controlled aerial targets.
 They would also provide specialized training for new Army equipment as needed.
 In 1952, Rocky Mountain Arsenal in Denver, Colorado transferred chemical agents and chemical munitions to Pueblo Army Depot for secure storage.
 In 1974 Pueblo Army Depot was redesignated as Pueblo Depot Activity.
Concord Naval Weapons Station was a military base established in 1942 north of the city of Concord, California at the shore of the Sacramento River where it widens into Suisun Bay.
 The station functioned as a World War II armament storage depot, supplying ships at Port Chicago.
 Concord NWS continued to support war efforts during the Korean War, the Vietnam War and the Gulf War, processing and shipping thousands of tons of materiel out across the Pacific Ocean.
 During World War II it also had a Naval Outlying Field at the southern edge of the base.
 It ceased being an operating airfield after World War II.
The dreadnought was the predominant type of battleship in the early 20th century.
 The first of its kind, the Royal Navy's "Dreadnought" , made such a strong impression on people's minds when launched in 1906 that similar battleships built subsequently were referred to generically as "dreadnoughts", and earlier battleships became known as "pre-dreadnoughts".
 "Dreadnought"' s design had two revolutionary features: an "all-big-gun" armament scheme, with more heavy-calibre guns than previous ships, and steam turbine propulsion.
 As dreadnoughts became a symbol of national power, the arrival of these new warships was a crucial catalyst in the intensifying naval arms race between the United Kingdom and Germany.
 With the launch of a single ship, "Dreadnought", the scales of naval power were reset overnight.
 As a result, dreadnought races sprang up around the world, including in South America, during the lead up to World War I.
 Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era.
 Within five years, new battleships had outclassed "Dreadnought".
 These more powerful vessels were known as "super-dreadnoughts".
 Most of the original dreadnoughts were scrapped after the end of World War I under the terms of the Washington Naval Treaty, but many of the newer super-dreadnoughts continued to be used throughout World War II.
 The only surviving dreadnought is USS "Texas" , located near the San Jacinto Battleground State Historic Site.
Nucourt is one of the communes of the Val-d'Oise department in the Île-de-France region of northern France and the location of limestone caves which were used as a World War II V-1 flying bomb storage depot.
The Defence Armament Depot, named the Kauri Point Armament Depot until 2010, is a New Zealand Defence Force munitions storage facility in the Auckland suburb of Chatswood which was originally built for the Royal New Zealand Navy.
 The Depot has access to Waitemata Harbour.
 The armament depot was established in 1935, and was considerably expanded during the Second World War.
 A program to modernise the facility was announced in 2011.
Ouvrage Simserhof is a "gros ouvrage" of the Maginot Line, located near the community of Sierstal in the French "département" of Moselle.
 Simserhof is adjoined by "petit ouvrage" Rohrbach and "gros ouvrage" Schiesseck, and faces the German frontier.
 Located 4 km to the west of Bitche, the "ouvrage" derived its name from a nearby farm.
 It was a part of the Fortified Sector of Rohrbach.
 During the Battle of France in 1940, Simserhof supported its neighboring fortifications with covering artillery fire, with partial success.
 After the surrender of France, it was occupied by the Germans as a storage depot for torpedoes, and later resisted the American advances of late 1944.
 Taken by the Americans, it was briefly re-occupied by the Germans during Operation Nordwind.
 Following the war it was repaired for use by the French Army, but was proposed as a museum of the Maginot Line as early as the 1960s.
 Retained by the Ministry of Defense, Simserhof now functions as a museum, and has the most extensive visitor infrastructure of any of the preserved Maginot fortifications.
HMAS "Waterhen" is a Royal Australian Navy (RAN) base located in Waverton on Sydney's lower north shore in New South Wales, Australia.
 Constructed on the site of a quarry used to expand Garden Island in the 1930s, the location was used during World War II as a boom net maintenance and storage area.
 In 1962, the area was commissioned as a base of the RAN, and became home to the RAN's mine warfare forces.
 "Waterhen" was the first small-ship base established by the RAN, and from 1969 to 1979 was also responsible for the RAN's patrol boat forces.
