A new important step in high-energy gamma-ray astronomy has been made with the beginning of Fermi LAT observations. But, as usual, a lot of new problems arise, in particular, the number of unidentified discrete gamma-ray sources is about 40%. To solve them it is necessary to improve the angular resolution up to 0.01°, the energy resolution up to 1%, and to extend the observable energy range to 3000 GeV. A new generation instrument, the GAMMA-400 gamma-ray telescope, will correspond to these requirements. The instrument will be also equipped with transition radiation detector and neutron detector to measure electron and positron fluxes more reliably. The GAMMA-400 launch is planned in 2016-2017.
