The first stage of Antares burns RP-1 (kerosene) and liquid oxygen (LOX). As Orbital had little experience with large liquid stages and LOX propellant, the first stage core was designed and is manufactured in Ukraine by Yuzhnoye SDO[13] and includes propellant tanks, pressurization tanks, valves, sensors, feed lines, tubing, wiring and other associated hardware.[21] Like the Zenit—also manufactured by Yuzhnoye—the Antares vehicle has a diameter of 3.9 m (150 in) with a matching 3.9 m payload fairing.[3]
