Kvant is a light-lift family of launch vehicles, which delivers communication satellite systems, remote sensing systems, scientific and applied research purposes in low orbit configurations. RSC Energia developed the ecologically safe, light-class launch vehicle based on proven and highly reliable elements of earlier vehicles. Kvant employs liquid oxygen-kerosene engines RD-120 being used in Zenit for its 1st stage ground launch activity. The upper stage DM-SL currently being used in the Zenit-3SL (Sea Launch Complex) was modified to serve as the 2nd stage component. The control system is a high-frequency 3-axes gyro stabilized platform PV-300 accompanied with modern digital computer (Biser-3). The payload fairing used is that of the Proton LV.
The new Kvant-1 launcher is a two-stage launch vehicle, which burns liquid oxygen and kerosene fuels, and is structurally similar to the Kvant. Kvant-1 1st stage employs the core engine from the Soyuz launcher; the 2nd stage utilizes the 3rd stage engines of the Soyuz. The Kvant-1 flight control system is based on the Yamal spacecraft flight control system. Kvant-1 can deliver payloads to low and medium-high near-Earth orbits.
