In addition to these developments, the government of Iran had begun alongside American and British corporations to enter the licensed manufacturing of several different types of military equipment. Iran was very active in manufacturing Bell Helicopters, Boeing Helicopters and TOW missiles. As well many bases were under construction to house all of the military equipment. Two very notable and large bases that were to be built were in Abadan, where a massive infantry unit and airforce would serve to protect Iran from any Iraqi aggression, while the other in Chabahar was to house a port capable of housing submarines and aircraft carriers which would serve to allow Iran to patrol the Indian Ocean.
