April 11, 2012, Iranian military officials announced their indigenous tank, Zolfaqar-3, has been upgraded with the latest in laser targeting.

The Zolfaqar tank (not to be confused with many other Iranian weapons using the same name) was developed over the decades by experimenting with U.S. M60 tanks, British Chieftain tanks and Soviet/Russian T-72 tanks.

The production version looks a lot like the U.S. M1 Abrams but armed with a Russian 125mm auto-loading main gun.

It probably uses the same “chobham” armor that the British Challenger tank uses, as it was Iranian engineers who developed it and then requested the British company Vickers to make them a new tank with it.  That tank became the Challenger, but it never made it to Iran because of the 1979 Revolution.

The Zolfaqar-3 reportedly weighs 36 metric tons (39.6 tons) and has a 780 hp diesel piston engine (the U.S. M1 has a 1,500 shp turbine/jet engine which uses diesel).

Iran has built their own version of the M134 Minigun.  The Iranian gatling gun fires 7.62mm bullets (not sure if its x39mm, or x51mmNATO, or x54mm) at a rate of 4000 to 6000 rounds per minute (it’s designed to take out a lot of troops in one pass).

Iran announced this weapon in 2010, but they are claiming that all their military units, designated to use the minigun, are now equipped with it.

Iran has also developed a radar system designed to detect stealth aircraft. Iranian media reported that the radar can detect aircraft with a “very low radar cross section”.

The new radar is called Samen, and is due to begin operations by March 19.
