The mechanics of the tanks are reputed to be good. However, the tank is a system, which has to be well integrated, if it is to work well. Indian's are very adept scientists. However, the Indian Defense Manufacturing establishment has repeatedly gone beyond it's deadline, in regard to it's various projects. In times of peace, there is no emergency, but it does not show the defense ministry in good light, which includes the scientists, civil servants, and everyone involved. No one is accountable, because for five years, the ruling coalition politicians are their own masters. If the politicians were responsible, then works would have progressed on a "War Footing". I believe, The Indian Government should hire the best engineers and personnel, to make the equipment required. The ownership of the project, would be with the Indian Government, while the personnel would be hired from friendly countries. Gradually, Indian scientists, and personnel, could be introduced into the process, of manufacture.
