The Start program consists of two launch vehicles, the Start-1 and the Start. The Start-1 launch vehicle is a converted ICBM known as the Topol RT-2PM. It is one of the smallest launch vehicles in the world, measuring 22.7 m (74.5 ft) in height and having a capacity of lifting 632 kg (1393 lbm) to a LEO altitude of 200 km. The Start-1 consists of four stages. The Start launch vehicle is similar to the Start-1 however it adds a fifth stage. Start is larger and has a higher payload capacity, but has not experienced a successful launch. Both spacecraft are unique in that they are the only launch vehicles in the world to use solid propellant for all stages.

Both launch vehicles are operated by ZAO Puskovie Uslugi in Russia and by the United Start Corporation in the United States. Start-1 has a price tag of US$9 million for a launch while the larger Start costs US$10.5 million. 

The first Start-1 was successfully launched in 1993, delivering a non-commercial payload to orbit.  The only Start to attempt a launch was destroyed in 1995. The first commercial launch of the Start-1 occurred in 1997, raising its payload of an imaging spacecraft for the Earthwatch Company. As of last June ('99), four successful Start-1 flights have been recorded including its first flight without incident.
