About the book: 2021 / Sergei Pavlovich Invincible (1921–2014) is one of a galaxy of legendary Soviet designers who, in conditions of strict secrecy, forged the defense shield of our country for decades. Having worked his way up from engineer to general designer at Kolomenskoye KBM, he led the creation of many types of rocketry that are still in service with the Russian army. Only in recent years his name became known to the general public and was written in golden letters in the history of the Russian defense industry. Valery Petrov’s book is the first biography of Invincible, truthfully and fully telling about his life and work, about the formidable “products” of the military-industrial complex created under his leadership.
