Cyclone - 4 Launch Vehicle 

At this moment, the Ukrainian Yuzhnoye engineering office is working on the development of Cyclone-4, a new Cyclone series vehicle to be commercialized exclusively by ACS. The Cyclone series of launch vehicles is one of the most successful series of rockets ever developed, with only six failures in 226 launches. The Cyclone series pre-launch operations are automatic, which increases launch safety, and reduces the personnel necessary for the launch operation.  

The first vehicle of the Cyclone series, the Cyclone-2 rocket, was designed by Yuzhnoye based on the SS-9 Scarp Intercontinental Ballistic Missile at the end of the 1960s. The Cyclone-2 has two stages, equipped with engines that use liquid propellant, and is able to inject payloads of up to 3,300 kg into low Earth orbit. The Cyclone-2 rockets have performed 105 missions, all successful. The last Cyclone-2 launch took place in May 28, 2004. 

In the late 1970s, the Cyclone-3 three-stage launch vehicle was designed. This vehicle uses the successful Cyclone-2 rocket for the first two stages, and a new third stage which also employs a liquid propellant. The Cyclone-3 rocket performed around 120 launches to date with only 6 failures. The Cyclone-3 launcher is capable of placing 4,000 kg in low Earth orbit, and has launched Soviet satellites, as well as satellites designed by other international programs.  
 

The Cyclone-4 rocket will also use the successful Cyclone-2 as its first two stages. The third stage is a new project with a larger propellant capacity, and a new rocket engine with multiple ignition capacity. The new third stage will also use a modern control system capable of precise orbit injections. The new third stage will enable the Cyclone-4 to inject 5,300 kg in low Earth orbit, or 1,600 kg into a geo-transfer orbit. In addition, a new payload unit is under development for the Cyclone-4. The new payload unit has a diameter of 4 meters and has controlled temperature and cleanness conditions.
