From Sputnik to Buran: the Chief Designer who built the brains of the Soviet space age
In 1946 Korolev came to the young Pilyugin and said, "I need a brain that knows where the rocket is going." Starting from a single gyroscope, Pilyugin spent 35 years designing the mind that steered every Soviet spaceflight.
Born near St. Petersburg to a military family, he graduated Bauman MVTU and worked as a precision mechanic at TsAGI. After studying V-2 wreckage in Germany, he became Chief Designer of autonomous control systems at NII-885 on Korolev's recommendation in 1946. His guidance, navigation, and control systems spanned virtually every major Soviet rocket: the R-1, R-7 (Sputnik and Gagarin), Proton, interplanetary probes, and the Buran shuttle. A member of the Council of Chief Designers alongside Korolev, Glushko, and Barmin, he helped direct the Soviet space program and was one of 72 Academicians who denounced Sakharov's Nobel Peace Prize in 1975.

Autonomous Inertial vs. Radio Command — The Guidance Struggle
The most acute technical debate in early Soviet rocketry concerned guidance philosophy. The radio-correction approach led by Mikhail Ryazansky relied on ground stations to adjust rocket trajectory, while the autonomous inertial approach championed by Pilyugin and Boris Chertok used only onboard gyroscopes and accelerometers to determine position independently. Radio guidance was simpler for a single target, but autonomous inertial offered a decisive military advantage: it was immune to electronic jamming and could target multiple objectives simultaneously.
Chertok recorded in his memoirs: "Even during those first years I advocated a purely autonomous inertial guidance system for long-range ballistic missiles. Ryazanskiy argued that my proposals were unrealistic. Pilyugin tried to stay out of the arguments, but privately he agreed with me." At a one-on-one meeting, Pilyugin told Chertok: "Don't get Mikhail started again. It's still early, and there's no need to offend him. And don't get Sergey set against radio control. It's not time yet." Pilyugin held firm technical convictions but pursued a gradual, consensus-preserving strategy within the political space of Korolev's Council of Chief Designers.
This internal struggle resurfaced within NII-885 in the mid-1950s. When Pilyugin's inertial camp and Konoplev's radio-control faction clashed over research and production priorities, Ryazansky, after consulting with Korolev, sided with Pilyugin, effectively settling the matter. Konoplev protested, but the tide had turned. The success of the R-7 ICBM made fully autonomous inertial guidance the standard for Soviet rocketry, and Pilyugin's NII-885 rose to a position of designing the 'brains' for every major vehicle from Sputnik to Buran.
