The Islamic Republic of Iran Navy Aviation (IRINA) (Persian: هواپیمایی نیروی دریایی آجا) or Havadarya (هوادریا) is the air component of the Islamic Republic of Iran Navy. It is one of the few air elements in any Persian Gulf navy, and has both fixed-wing aircraft and armed helicopters.
Aircraft
American aircraft types were introduced to the inventory, in the 1960s and 1970s: with European made aircraft comprising the more modern part of the fleet. Anti-submarine warfare (ASW) helicopters seem to be focused more on a transport role than actual ASW.
Supplemented by United States Navy examples that were abandoned by US forces during Operation Eagle Claw and used as spare parts source. It is believed that Iran got additional spare parts in black market in 2006-8 and up to six original plus one Eagle Claw RH-53Ds may be operational
Built by Agusta, in Italy. Operational number unknown. Iran is producing spare parts locally for its Bell helicopters, used by all Armed Forces branches.
