Iran's state TV is reporting the country's navy relaunched one of its Russian-made submarines after repairing its systems with locally-made replacement parts.

Iran has tried to build a self-sufficient military program since 1992.

The Tuesday report says that navy personnel overhauled the Taregh, one of its three Kilo class submarines, replacing 18,000 components including radar-evading cover, engine parts, propellers and radars.

State TV showed video of the relaunch from a dry dock in an Iranian port .

Iran added the three Kilo class submarines to its underwater fleet in early 1990s soon after it founded its submarine unit. Several smaller Iranian-built submarines have also been deployed by its navy.
