High Quality Content by WIKIPEDIA articles! From 1925 to the Iranian Revolution in 1979, Iran was equipped with the very latest Western hardware. Cases exist where Iran was supplied with equipment even before it was made standard in the countries that developed it (for example the US F-14 Tomcat, or the British Chieftain Tank). Primary suppliers included the United States, Britain, France, the Federal Republic of Germany (West Germany), Italy, Israel, and the Soviet Union.
