Sea Launch uses the Ukrainian-produced Zenit rocket and Russian-built Block DM-SL upper stage.

The first and second stages of the booster are provided by Yuzhnoye/Yuzhmash, and are manufactured in Dnepropetrovsk, Ukraine. The Zenit booster is similar to the two-stage Zenits that have flown over 35 times since 1985. The first stage is powered by an RD-171 engine with four nozzles; the second stage is equipped with a single nozzle RD-120 powerplant.

The Block DM-SL is built by Energia of Moscow, Russia. This upper stage is responsible for delivering the future satellite payloads into their intended orbits during a series of up to five firings. The stage uses one 11D58M engine.

Boeing of Kent, Wash., provides the payload fairing and interstage structure.

The rocket's widest diameter is 14 feet, overall length of about 200 feet, all stages are kerosene and liquid oxygen fueled and the capacity to geostationary transfer orbit is 5,000 kilograms.
