The NICA goals are providing of colliding beams for studies of hot and dense strongly interacting baryonic matter and spin physics. The NICA complex injection facility consists of four accelerators: Alvarez-type linac LU-20 of light ions up to 5 MeV/u; heavy ion linac HILAC with RFQ and IH DTL sections at energy 3.2 MeV/u; superconducting Booster synchrotron at energy up 578 MeV/u; superconducting synchrotron Nuclotron at gold ion energy 3.85 GeV/u. In the nearest future the old LU-20 will be substituted by a new light ion linac for acceleration of 2<A/z<3 ions up to 7 MeV/u with additional two acceleration sections for protons, first IH section for 13 MeV and the second one - superconducting for 20 MeV. The status of NICA injec-tion facility is under discussion.
