Iran’s recent failed ballistic missile launch from a submerged “midget” submarine has once again drawn attention to Iran’s military ties with another of America’s most outspoken opponents, North Korea.

The failed missile test is said to have been Iran’s first with the Jask-2 underwater cruise missile, a missile design intelligence experts believe to be a copy of previous missiles tested in North Korea.  Such a revelation would hardly be a surprise, as the Ghadir class electric submarine used as a platform to launch the cruise missile is also a direct copy of the North Korean Yono class sub.

The similarities in Iran’s ballistic missile progress and North Korea’s are a bit too much to be considered coincidence, despite Iran’s agreement to end their pursuit of nuclear weapons.

“The very first missiles we saw in Iran were simply copies of North Korean missiles,” said Jeffrey Lewis, a missile proliferation expert at the Middlebury Institute of International Studies at Monterey. “Over the years, we’ve seen photographs of North Korean and Iranian officials in each other’s countries, and we’ve seen all kinds of common hardware.”
