The base is "one of numerous tactical underground air bases for the army's air force built in different areas of the country in recent years," according to IRNA.
It is capable of readying fighter jets to respond to potential offensives, such as those simulated by the US and Israel in their recent military exercise, state media said.
The location of the base was not disclosed.
Iran's air force possesses a variety of US-made military aircraft from before the 1979 revolution, as well as Russian-made MiG and Sukhoi planes. However, decades of Western sanctions have made it difficult to obtain spare parts and maintain the aging fleet.
