United States Army Air Forces
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1945). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed among the Air Corps, General Headquarters Air Force, and the groun ...

SS Nieuw Amsterdam (1938)
The ''Nieuw Amsterdam'' was a Dutch ocean liner built in Rotterdam for the Holland America Line. Construction and launch Originally she was to be named ''Prinsendam'', however during construction, Holland America Line decided to name their new flagship ''Nieuw Amsterdam'', in honor of the Dutch settlement of New Amsterdam, modern-day New York. Construction on the new liner was carried out at the N.V. Rotterdam Drydock Company. Christened by Queen Wilhelmina in April 1937, ''Nieuw Amsterdam'' was, at 36,982 tonnes, the largest liner ever constructed in the Netherlands up to that time. Proudly she was dubbed the Dutch "Ship of peace" since there were no provisions for possible war use incorporated in her design. At the time ''Nieuw Amsterdam'' was more completely protected against fire, had the largest air conditioning plant and the highest percentage of private baths of any ship afloat. The ship was also the only liner with a fully equipped and air conditioned theater. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boeing B-17 Flying Fortress
The Boeing B-17 Flying Fortress is a four-engined heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). Relatively fast and high-flying for a bomber of its era, the B-17 was used primarily in the European Theater of Operations and dropped more bombs than any other aircraft during World War II. It is the third-most produced bomber of all time, behind the four-engined Consolidated B-24 Liberator and the multirole, twin-engined Junkers Ju 88. It was also employed as a transport, antisubmarine aircraft, drone controller, and search-and-rescue aircraft. In a USAAC competition, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, then introduced it into service in 1938. The B-17 evolved through numerous design advances but from its inception, the USAAC (later, the USAAF) promoted the aircr ...

Brest, France
Brest (; ) is a port city in the Finistère department, Brittany. Located in a sheltered bay not far from the western tip of the peninsula, and the western extremity of metropolitan France, Brest is an important harbour and the second French military port after Toulon. The city is located on the western edge of continental France. With 142,722 inhabitants in a 2007 census, Brest forms Western Brittany's largest metropolitan area (with a population of 300,300 in total), ranking third behind only Nantes and Rennes in the whole of historic Brittany, and the 19th most populous city in France; moreover, Brest provides services to the one million inhabitants of Western Brittany. Although Brest is by far the largest city in Finistère, the ''préfecture'' (regional capital) of the department is the much smaller Quimper. During the Middle Ages, the history of Brest was the history of its castle. Then Richelieu made it a military harbour in 1631. Brest grew around its arsenal u ...

Close Air Support
In military tactics, close air support (CAS) is defined as air action such as air strikes by fixed or rotary-winged aircraft against hostile targets near friendly forces and require detailed integration of each air mission with fire and movement of these forces and attacks with aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.''Close Air Support''. United States Department of Defense, 2014. The requirement for detailed integration because of proximity, fires or movement is the determining factor. CAS may need to be conducted during shaping operations with Special Operations Forces (SOF) if the mission requires detailed integration with the fire and movement of those forces. A closely related subset of air interdiction (AI), battlefield air interdiction, denotes interdiction against units with near-term effects on friendly units, but which does not require integration with friendly troop movements.

Coastal Defense And Fortification
300px, Castillo San Felipe de Barajas in Cartagena de Indias, Colombia, an example of an Early Modern coastal defense Coastal defence (or defense) and coastal fortification are measures taken to provide protection against military attack at or near a coastline (or other shoreline), for example, fortifications and coastal artillery. Because an invading enemy normally requires a port or harbour to sustain operations, such defences are usually concentrated around such facilities, or places where such facilities could be constructed. Coastal artillery fortifications generally followed the development of land fortifications, usually incorporating land defences; sometimes separate land defence forts were built to protect coastal forts. Through the middle 19th century, coastal forts could be bastion forts, star forts, polygonal forts, or sea forts, the first three types often with detached gun batteries called "water batteries". Coastal defence weapons throughout history were heavy na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D-Day
The Normandy landings were the landing operations and associated airborne operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. Codenamed Operation Neptune and often referred to as D-Day, it was the largest seaborne invasion in history. The operation began the liberation of France (and later western Europe) and laid the foundations of the Allied victory on the Western Front. Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on D-Day was far from ideal, and the operation had to be delayed 24 hours; a further postponement would have meant a delay of at least two weeks, as the invasion planners had requirements for the phase of the moon, the tides, and the time of day that meant only a few days each month wer ...

Operation Overlord
Operation Overlord was the codename for the Battle of Normandy, the Allied operation that launched the successful invasion of German-occupied Western Europe during World War II. The operation was launched on 6 June 1944 (D-Day) with the Normandy landings. A 1,200-plane airborne assault preceded an amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, and more than two million Allied troops were in France by the end of August. The decision to undertake a cross-channel invasion in 1944 was taken at the Trident Conference in Washington in May 1943. General Dwight D. Eisenhower was appointed commander of Supreme Headquarters Allied Expeditionary Force, and General Bernard Montgomery was named commander of the 21st Army Group, which comprised all the land forces involved in the invasion. The coast of Normandy of northwestern France was chosen as the site of the invasion, with the Americans assigned to land at sectors ...

801st Bombardment Group (Provisional)
Operation Carpetbagger was a World War II operation to provide aerial supply of weapons and other '' matériel'' to resistance fighters in France, Italy and the Low Countries by the U.S. Army Air Forces that began on 4 January 1944. History In late 1943, the 22d Antisubmarine Squadron of the Eighth Air Force was disbanded at RAF Alconbury and its aircraft used to form the 36th and 406th Bombardment Squadrons under the 482nd bomb group. After some shuffling of commands, these two squadrons were placed under the provisional 801st Bomb Group at RAF Harrington at the beginning of 1944 and the first "Carpetbagger" missions were carried out by this unit under the control of General "Wild Bill" Donovan's Office of Strategic Services (OSS). In April 1944, the group moved to RAF Harrington (Station 179), a more secluded and thus more secure airbase. A month later, in advance of the expected invasion of Europe, it was expanded to four squadrons to increase its capabilities and to p ...
