IACTs are one of the key parts of the TAIGA observatory and designed for study of gamma rays and charged cosmic rays in the energy range of 10${}^{13}{-}10^{18}$ eV. The first IACT was designed and fabricated at the JINR workshop and has been operating since 2016 in the Tunka valley. The second one has been assembled there at September 2018 and the production of the third one is in progress to be transported to the Tunka valley in August 2019. The R&D to fabricate focusing glass mirrors directly in JINR is underway. The report presents the TAIGA IACT main characteristics and the results of the comparison between the JINR glass mirrors and composite mirrors (Media Lario company, Italy).
