The Lockheed YF-12 is an American Mach 3+ capable, high-altitude interceptor prototype, developed and manufactured by American aerospace company Lockheed Corporation. The interceptor was developed during the late 1950s and early 1960s as a potential replacement for the F-106 Delta Dart interceptor for the United States Air Force (USAF).

The Boeing F-47 is an American air superiority sixth-generation fighter aircraft to be developed by Boeing for the United States Air Force (USAF) under the Next Generation Air Dominance (NGAD) program. [1] [2] It is designed to be the successor to the Lockheed Martin F-22 Raptor.USAF officials said experimental tests have been flown since 2020, and the service aims to field it by decade's end ...

YF-12採用原本為XF-108研發的 AN/ASG-18 雷達，因此在A-12上延伸到機鼻的兩側延伸面被切除一部分，用以容納雷達和直徑更大的鼻錐。 此外，YF-12由單座改為雙座，後座專門操作複雜的ASG-18雷達。 在 風洞 測試過程中發現YF-12有方向軸上的穩定問題，於是在機身下方加上一片大型可摺疊的安定面，另外在兩個發動機艙下方加上較小的固定安定面。 第一架YF-12於1963年8月進行試飛，次年3月，一架YF-12A成功進行一次攔截演習；以高度19695 公尺 （65000英 …

2020年3月18日 · This combat adaptation of the Blackbird, called the F-12, was set to be equipped by Lockheed Martin with a powerful AN/ASG-18 radar capable of detecting aerial targets over 800km away. The interceptor was also set to carry four long-range AIM-47 missiles, with a range of over 160km and a potent 100-pound high explosive warhead.

The YF-12 was developed in the 1960s as a high-altitude, Mach 3 interceptor to defend against supersonic bombers. Based on the A-12 reconnaissance aircraft, the YF-12A became the forerunner of the highly-sophisticated SR-71 strategic reconnaissance aircraft.

2020年1月16日 · Still the Air Force was still in need of a Mach 3 interceptor and Lockheed Skunk Works chief, Kelly Johnson, saw an opportunity to give them what they needed. Based on the CIA’s new spyplane, the A-12, Johnson proposed an interceptor variant known internally as …

F-12B是计划中YF-12A的生产型，为增大导弹挂载量，机身有所加长。 1965年3月18日，YF-12A首次进行了发射导弹攻击试验，并击落了Q-2C靶机。 尽管YF-12A进行了一系列武器发射试验，并取得了成功，但当时的美国 国防部长 麦克纳马拉 以资金困难为由，没有批准空军采用该机的生产型F-12B。 结果，YF-12A仅以试制3架而告终。 1968年1月，美国国防部发布通告中止执行该机研制计划，随之1号机被封存，2号机和3号机则由NASA一直使用到70年代末。 3号机曾 …
