The name “Proton” was later adopted for the entire launch vehicle. The UR-500, initially designed as an intercontinental ballistic missile, was repurposed as a heavy-lift launch vehicle capable of carrying substantial payloads into space. It featured a two-stage design with the first stage using six RD-253 engines and the second stage powered by four RD-0210 engines. This configuration allowed it to deliver payloads of up to 20,000 kilograms to low Earth orbit. The Proton was developed under the guidance of the chief designer, Vladimir Chelomey. The rockets were manufactured at the Khrunichev Machine-Building Plant. The Proton launch vehicle has been instrumental in deploying various significant satellites into space. Notably, it […]
