Following World War II, during the presidency of former Supreme Allied Commander Dwight Eisenhower, the US faced a defense and security issue previously unknown to mankind. The combined invention of the atomic bomb and long-range bombers, and the accelerating pace of development of rocketry meant that it was possible for a surprise enemy attack to wipe out their civilization. The next Pearl Harbor would not destroy our military; it would stop our culture.
Further compounding this problem was the culture of the enemy – the USSR. America was an open society; it was assumed that Soviet intelligence was able to travel the country and make estimates of what US capabilities were through conventional espionage. The same was not true of the Soviet Union’s closed, totalitarian state. This created the backdrop for an urgent need for new tools to conduct strategic reconnaissance.
Previously, reconnaissance flights into the Soviet Union were conducted by conventional airplanes. They were modified B-47s or B-57s. Unfortunately, they were not optimized for their newly defined need. What was needed was a strategic reconnaissance aircraft; and to achieve that several components were needed.
Four components were required to create the correct strategic reconnaissance aircraft;
- An airplane that could carry the correct equipment and match the mission requirements.
- A camera capable of photographing at the appropriate resolution during the mission.
- Film which met the mission requirements.
- A system which allowed and made use of the results of the strategic reconnaissance missions.
Each of these components then have their own sub-components. For the airplane, it must include whichever inventions allowed it to be capable of;
- Carrying at least one crew member (at the time, pilots were required).
- Flying at altitude of over 60,000 feet (20 km) to avoid anti-aircraft missiles.
- Carrying the camera payload.
- Continuous flights over large swaths of the Soviet Union without refueling.
- Existing in a socio-political system which made use of its strategic reconnaissance traits.
