A brief summary is given of the experimental research into the detection of extraterrestrial gravitational radiation performed in Russia since the late 1960s. Various aspects of this topic are reviewed, including experiments with resonant detectors, geophysical methods for detecting low-frequency gravitational waves, and high frequency versions of the gravitational `Hertz experiment'. A description is given of the current situation concerning the unique optoacoustic gravitational detector OGRAN mounted in the underground laboratory of the Baksan neutrino observatory, Institute for Nuclear Research, Russian Academy of Sciences. Prospects are examined for building a Russian Federation based long base gravitational wave interferometer integrated into the global network of gravitational antennas.
