“The silos are a part of the swift reaction unit of the [IRGC] missile brigade; missiles are stored vertically, ready to be launched against pre-determined targets.”-General Asghar Qelich-Khani
Iranian Revolutionary Guard Corps officials revealed, on June 27, that not only does Iran have underground missile silos, but they’ve had underground silos for 15 years.
The “pre-determined” targets are Israel, and U.S. bases in the Middle East. Iranian military officials say they have no reason to build missiles with longer range than being able to hit Israel. Iran says the only countries that threaten them is Israel and the United States. They don’t need ballistic missiles that can hit the U.S., because there are so many U.S. targets in the Middle East.
Iran also successfully launched 14 missiles on June 28, including long range ballistic missiles.
