Second Schweinfurt Raid
The second Schweinfurt raid, also called Black Thursday, was a World War II air battle that took place on 14 October 1943, over Nazi Germany between forces of the United States 8th Air Force and German ''Luftwaffe'' fighter arm (''Jagdwaffe''). The American bombers conducted a strategic bombing raid on ball bearing factories to reduce production of these vital parts for all manner of war machines. This was the second attack on the factories at Schweinfurt. American wartime intelligence claimed the first Schweinfurt–Regensburg mission in August had reduced bearing production by 34 percent but had cost many bombers. A planned follow-up raid had to be postponed to rebuild American forces. As the squadrons rebuilt, plans for the return mission were modified based on the lessons learned. Planners added additional fighter escorts to cover the outward and return legs of the operation and sent the entire force against Schweinfurt alone, instead of splitting the force. Despite these ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eighth Air Force
The Eighth Air Force (Air Forces Strategic) is a numbered air force (NAF) of the United States Air Force's Air Force Global Strike Command (AFGSC). It is headquartered at Barksdale Air Force Base, Louisiana. The command serves as Air Forces Strategic – Global Strike, one of the air components of United States Strategic Command (USSTRATCOM). The Eighth Air Force includes the heart of America's heavy bomber force: the Northrop Grumman B-2 Spirit stealth bomber, the Rockwell B-1 Lancer supersonic bomber, and the Boeing B-52 Stratofortress heavy bomber aircraft. Established on 22 February 1944 by the redesignation of VIII Bomber Command at RAF Daws Hill in High Wycombe, England, the Eighth Army Air Force (8 AAF) was a United States Army Air Forces combat air force in the European Theater of World War II (1939/41–1945), engaging in operations primarily in the Northern Europe area of responsibility; carrying out strategic bombing of enemy targets in France, the Low Countrie ...

Ball Bearing
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. History Although bearings had been developed since ancient times, the first mod ...

Combined Bomber Offensive
The Combined Bomber Offensive (CBO) was an Allies of World War II, Allied offensive of strategic bombing during World War II, strategic bombing during World War II in Europe. The primary portion of the CBO was directed against Luftwaffe targets which was the highest priority from June 1943 to 1 April 1944. The subsequent highest priority campaigns were against V-weapon installations (June 1944) and Oil Campaign chronology of World War II, petroleum, oil, and lubrication (POL) plants (September 1944). Additional CBO targets included Transportation Plan, railyards and other transportation targets, particularly prior to the invasion of Normandy and, along with army equipment, End of World War II in Europe, in the final stages of the war in Europe. The British bombing campaign was chiefly waged by night by large numbers of heavy bombers until the latter stages of the war when German fighter defences were so reduced that daylight bombing was possible without risking large losses.

ZF Sachs
ZF Sachs AG, also known as Fichtel & Sachs, was founded in Schweinfurt in 1895 and was a well-known German family business.

Kugelfischer
Kugelfischer injection (also called ''System Kugelfischer'') is the name for a mechanical fuel injection (MFI) pump. It was produced by FAG Kugelfischer and later by Robert Bosch GmbH Derived from diesel pumps from the early 1960s, the Kugelfischer system was a mechanical injection pump for performance vehicles. It was among the first units with manufacturer-customizable fuel delivery maps which used rpm, throttle position, temperature, and sometimes barometric pressure as inputs. This was accomplished mechanically, not electronically, using cones (irregularly shaped, two-dimensional cams) to encode the maps. In the late 1960s and early 1970s, it was fitted to a variety of production vehicles from BMW, Ford UK Ford commonly refers to: * Ford Motor Company, an automobile manufacturer founded by Henry Ford * Ford (crossing), a shallow crossing on a river Ford may also refer to: Ford Motor Company * Henry Ford, founder of the Ford Motor Company * Ford F ..., Lancia, Peug ...

USAAF Map Of The Raid On Schweinfurt, 14 October 1943
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 ground ...

RAF Bomber Command
RAF Bomber Command controlled the Royal Air Force's bomber forces from 1936 to 1968. Along with the United States Army Air Forces, it played the central role in the strategic bombing of Germany in World War II. From 1942 onward, the British bombing campaign against Germany became less restrictive and increasingly targeted industrial sites and the civilian manpower base essential for German war production. In total 364,514 operational sorties were flown, 1,030,500 tons of bombs were dropped and 8,325 aircraft lost in action. Bomber Command crews also suffered a high casualty rate: 55,573 were killed out of a total of 125,000 aircrew, a 44.4% death rate. A further 8,403 men were wounded in action, and 9,838 became prisoners of war. Bomber Command stood at the peak of its post-war military power in the 1960s, the V bombers holding the United Kingdom's nuclear deterrent and a supplemental force of Canberra light bombers.
