冷战时期,核动力飞机的研制并不仅美国一家。20世纪40年代末,苏联在掌握核技术后,也萌生了研制核动力飞机的念头。最初,由于核弹研制技术的落后,苏联没有认真研制核动力飞机。鉴于美国率先研制核动力飞机,以及苏联首批研制的国产战略轰炸机不具备将核武器投送到假想敌领空的能力,苏联才决定拨款研制核动力飞机。核动力飞机理论上的最大优点是,不仅可以增加航程,而且可以具备超音速飞行能力,甚至拥有很高的费效比。尽管核动力飞机的研制以失败告终,
Cold-war period, the development of nuclear-powered aircraft and not only the United States. In the late 1940s, after the Soviet Union mastered nuclear technology, it also initiated the idea of developing a nuclear-powered aircraft. Initially, the Soviet Union did not seriously develop its nuclear-powered aircraft due to its backward technology in research and development of nuclear bombs. Given that the United States pioneered the development of nuclear-powered aircraft and the first domestic strategic bombers developed by the Soviet Union did not have the capability to deliver nuclear weapons to the imaginary enemy’s air space, the Soviet Union decided to allocate funds for the development of nuclear-powered aircraft. The biggest theoretical advantage of nuclear-powered aircraft is that it can not only increase range, but also have supersonic flight capability, and even have a high cost-effectiveness ratio. Although the development of nuclear-powered aircraft ended in failure,
