The project of an EAS Cherenkov array in the Tunka valley/Siberia with an area of about 1 km2 is presented. The new array will have a ten times bigger area than the existing Tunka-25 array and will permit a detailed study of the cosmic ray energy spectrum and the mass composition in the energy range from 10^15 to 10^18 eV.
