  • The Norden bombsight was a tachometric bombsight used by the United States Army Air Forces (USAAF) and the United States Navy during World War II, and the United States Air Force in the Korean and the Vietnam Wars to aid the crew of bomber aircraft in dropping bombs accurately. Key to the operation of the Norden were two features; an analog computer that constantly calculated the bomb's trajectory based on current flight conditions, and a linkage to the bomber's autopilot that let it react quickly and accurately to changes in the wind or other effects.Together, these features allowed for unprecedented accuracy in day bombing from high altitudes; in testing the Norden demonstrated a circular error probable (CEP) of 23 metres (75 ft), an astonishing performance for the era. This accuracy allowed direct attacks on ships, factories, and other point targets. Both the Navy and the AAF saw this as a means to achieve war aims through high-altitude bombing, without resorting to area bombing, as proposed by European forces. To achieve these aims, the Norden was granted the utmost secrecy well into the war, and was part of a then-unprecedented production effort on the same scale as the Manhattan Project. Carl L. Norden, Inc. ranked 46th among United States corporations in the value of World War II military production contracts.In practice it was not possible to achieve this level of accuracy in combat conditions, with the average CEP in 1943 being 370 metres (1,200 ft). Both the Navy and Air Forces had to give up on the idea of pinpoint attacks during the war. The Navy turned to dive bombing and skip bombing to attack ships, while the Air Forces developed the lead bomber concept to improve accuracy. Nevertheless, the Norden's reputation as a pin-point device lived on, due in no small part to Norden's own advertising of the device after secrecy was reduced during the war.The Norden saw some use in the post-World War II era, especially during the Korean War. Post-war uses were greatly reduced due to the introduction of radar-based systems, but the need for accurate daytime attacks kept it in service for some time. The last combat use of the Norden was in the US Navy's VO-67 squadron, which used them to drop sensors onto the Ho Chi Minh Trail as late as 1967. The Norden remains one of the best known bombsights of all time.
  • ノルデン爆撃照準器(ノルデンばくげきしょうじゅんき、英:Norden bombsight)とは、第二次世界大戦中、アメリカ陸軍航空隊(USAAF)にて採用されていた、爆撃機の搭乗員が正確に爆弾を投下できる様に援助するための照準器である。またこの照準器は当時最高機密として取り扱われた。日本本土を空襲したB-29や広島、長崎に原子爆弾を投下した「エノラ・ゲイ」「ボックスカー」にも取り付けられていた。またノルデン照準器を搭載したB29爆撃機などは朝鮮戦争やベトナム戦争にも参加している。爆撃照準器が無いそれ以前の高高度爆撃の目標物の破壊率はとても低かった。簡易爆撃照準器もまた同じである。
  • Il Norden è stato un computer elettro-meccanico stabilizzato giroscopicamente, utilizzato a bordo dei bombardieri dall'United States Army Air Forces nel corso della seconda guerra mondiale e successivamente dall'United States Air Force nelle guerre in Vietnam e Corea per individuare il punto esatto in cui sganciare le bombe.Il meccanismo di funzionamento di questo apparecchio venne tenuto in gran segreto dagli Stati Uniti durante tutto il corso della seconda guerra mondiale. Nonostante ciò Herman Lang, una spia tedesca che lavorava nell'industria in cui il Norden veniva prodotto, riuscì a consegnare alcuni progetti del macchinario all'Abwehr nel 1938. Di conseguenza, a partire dal 1942, l'industria tedesca Carl Zeiss cominciò a consegnare alla Luftwaffe apparecchi simili, denominati Lotfernrohr 7.
