Port of LondonThe Port of London is that part of the River Thames in England lying between Teddington Lock and the defined boundary (since 1968, a line drawn from Foulness Point in Essex via Gunfleet Old Lighthouse to Warden Point in Kent) with the North Sea and including any associated docks. Once the largest port in the world, it was the United Kingdom's largest port as of 2020. Usage is largely governed by the Port of London Authority ("PLA"), a public trust established in 1908; while mainly responsible for coordination and enforcement of activities it also has some minor operations of its own.
Schnellkampfgeschwader 210Schnellkampfgeschwader 210 (SKG 210) was a Luftwaffe fast-bomber wing during the Second World War. The unit was created in April 1941 and absorbed by the Zerstörergeschwader 1 on 4 January 1942. SKG 210 had its origins in Erprobungsgruppe 210 (Test Wing 210), formed at Köln-Ostheim airfield under the command of Hptm. Walter Rubensdörffer in July 1940 as the official service test unit for the new Messerschmitt Me 210, the intended successor to the earlier Messerschmitt Bf 110.
Destroyers-for-bases dealThe destroyers-for-bases deal was an agreement between the United States and the United Kingdom on September 2, 1940, according to which 50 , , and -class US Navy destroyers were transferred to the Royal Navy from the US Navy in exchange for land rights on British possessions. Generally referred to as the "twelve hundred-ton type" (also known as "flush-deck", or "four-pipers" after their four funnels), the destroyers became the British and were named after towns common to both countries.
AdlertagAdlertag ("Eagle Day") was the first day of Unternehmen Adlerangriff ("Operation Eagle Attack"), which was the codename of a military operation by Nazi Germany's Luftwaffe (German air force) to destroy the British Royal Air Force (RAF). The operation came after Britain rejected all overtures for a negotiated peace with Germany. However, Adlertag and subsequent operations failed to destroy the RAF or gain local air superiority. During the Battle of Britain, Hitler gave the German armed forces (Wehrmacht) a directive (Directive No.
Command of the seaCommand of the sea (also called control of the sea or sea control) is a naval military concept regarding the strength of a particular navy to a specific naval area it controls. A navy has command of the sea when it is so strong that its rivals cannot attack it directly. This dominance may apply to its surrounding waters (i.e., the littoral) or may extend far into the oceans, meaning the country has a blue-water navy. It is the naval equivalent of air supremacy.
Operational conversion unitAn operational conversion unit (OCU) is a unit within an air force whose role is to support preparation for the operational missions of a specific aircraft type by providing trained personnel. Operational conversion units teach pilots how to fly an aircraft and which tactics best exploit the performance of their aircraft and its weapons. The Royal Air Force and Royal Australian Air Force, among others, practise this method of training. The United States Navy calls its units in this role "fleet replacement squadrons".
Home FleetThe Home Fleet was a fleet of the Royal Navy that operated from the United Kingdom's territorial waters from 1902 with intervals until 1967. In 1967, it was merged with the Mediterranean Fleet creating the new Western Fleet. Before the First World War, it consisted of the four Port Guard ships. In 1905 it was disestablished, and from 1905 to 1907 remaining ships at a lesser state of readiness were split into the reserve divisions (Devonport Division, Nore Division, and Portsmouth Division).
War economyA war economy or wartime economy is the set of contingencies undertaken by a modern state to mobilize its economy for war production. Philippe Le Billon describes a war economy as a "system of producing, mobilizing and allocating resources to sustain the violence." Some measures taken include the increasing of Taylor rates as well as the introduction of resource allocation programs. Approaches to the reconfiguration of the economy differ from country to country.
White Cliffs of DoverThe White Cliffs of Dover are the region of English coastline facing the Strait of Dover and France. The cliff face, which reaches a height of , owes its striking appearance to its composition of chalk accented by streaks of black flint, deposited during the Late Cretaceous. The cliffs, on both sides of the town of Dover in Kent, stretch for eight miles (13 km). The White Cliffs of Dover form part of the North Downs. A section of coastline encompassing the cliffs was purchased by the National Trust in 2016.
