The plants will produce a ground-to-air missile dubbed the Qaem (Rising) and a surface-to-surface missile dubbed Toofan 5 (Flood).
The Qaem is designed to target helicopters at low and medium altitudes.
Iran unveiled the new plants as part of its celebrations for the 31st anniversary of the Islamic revolution later this month. On Wednesday, Iran launched a capsule carrying turtles, rats and worms aboard its Kavoshgar 3 (Explorer) missile in its first experiment in sending living creatures into space.
In December, Iran said it test-fired a long-range, upgraded Sejil 2 missile.
