Spektr-RG (Russian for Spectrum + Röntgen + Gamma; also called Spectrum-X-Gamma, SRG, SXG) is an international high-energy astrophysics observatory, which is being built under the leadership of the Russian Space Research Institute (IKI). Spektr-RG instrumentation includes 5 telescopes spanning the energy range from the far ultraviolet to the hard X-ray, plus an all-sky monitor.
The Spektr-RG programme was revived in 2005 and the spacecraft currently in development and scheduled for launch in 2016. The observatory is intended to study the interplanetary magnetic field, galaxies and black holes.

Development of an early version of Spektr-RG was started in mid-1990s and was cancelled in 2002. Initial launch date was set to 1995, but later postponed as far as 2008, until it was finally cancelled in 2002. However, some of the instruments have been completed, e.g., an X-ray telescope by Leicester University (JET-X) and an ultraviolet telescope by Tel-Aviv University (TAUVEX).
