Tehran's Air Force Museum is a specialist aviation stop, most appealing if you are interested in aircraft, military history, or Iran's complicated 20th-century relationship with foreign technology. Displays typically focus on planes, equipment, and the institutional history of Iranian military aviation.
It sits below Tehran's major museum tier, but it can be rewarding for the right traveler. Pair it with other north or west Tehran stops, and check opening conditions before making a special trip. The value is in seeing a side of modern Iran that rarely appears in palace or archaeology museums.
