Investigation Summary
The mission, codenamed 'Grand Slam', was the first attempted trans-Soviet U-2 flight, intended to overfly high-priority targets including the Baikonur and Plesetsk Cosmodromes and the Chelyabinsk-65 plutonium plant. The aircraft, Article 360, was detected by Soviet radar shortly after entering airspace. Because the U-2 operated at approximately 70,000 feet, Soviet interceptor aircraft were unable to reach it. Near Sverdlovsk, a battery commanded by Mikhail Voronov fired a salvo of S-75 Dvina (SA-2 Guideline) missiles. One missile exploded behind the aircraft, causing structural failure. Powers was thrown forward in the cockpit and struggled to exit due to his oxygen hose; he eventually bailed out without activating the aircraft's self-destruct mechanism. During the chaotic engagement, Soviet air defenses also targeted two pursuing MiG-19s that had failed to update their IFF codes for the May Day holiday, resulting in the death of Senior Lieutenant Sergei Safronov.
Final Conclusions
The aircraft was destroyed by the proximity blast of a surface-to-air missile. The pilot was convicted of espionage in a Soviet show trial and sentenced to ten years of confinement, but was later exchanged in February 1962 for Soviet spy Rudolf Abel. A 1962 CIA board of inquiry and subsequent declassified reports concluded that Powers had acted honorably and followed procedures to the extent possible under the extreme G-forces of the breakup.

Systems & Failure Modes
S-75 Dvina (SA-2 Guideline)
The Soviet surface-to-air missile system that successfully downed the U-2 using a high-explosive fragmentation warhead.
Destruction Device
An explosive charge designed to destroy the U-2's sensitive camera equipment in the event of a crash, which Powers did not activate before bailing out.
IFF (Identification Friend or Foe)
The transponder system on the Soviet MiG-19s which had not been updated with new codes, leading to the friendly fire shootdown of a Soviet interceptor.
Interesting Facts
- 01The U-2 was flying at an altitude of approximately 70,000 feet when it was intercepted.
- 02Powers carried a 'suicide pin' containing saxitoxin but chose not to use it.
- 03The incident led to the immediate collapse of the 1960 Paris Summit between Eisenhower and Khrushchev.
- 04The wreckage of Article 360 remains on display at the Central Armed Forces Museum in Moscow.
- 05The total fatalities include one Soviet pilot killed by his own air defenses during the intercept attempt.
Safety Actions & Advisories
Shift to Satellite Reconnaissance
The vulnerability of manned overflights exposed by the incident accelerated the development and deployment of reconnaissance satellites like Project Corona.
