Аннотация:We report the results of the spectroscopic observations carried out at the SAO RAS 6-m telescope for the optical components of nine new extended radio sources found in the NVSS catalog. The measured redshifts of the host galaxies lie in the range of z = 0.1-0.4. Physical sizes of the radio sources were calculated within the standard cosmological model. The two most extended objects, 0003+1512 and 0422+0351, reach sizes of 2.1 Mpc and 4.0 Mpc respectively. This is close to the maximum size of known radio sources
