An SLBM flies at like M4 no way anything could shoot it down. Also multiple warheads once it re-enters atmosphere.
Are there still Soviet drone subs at the bottom of Pearl Harbor/Puget/SD bay?
IRAN'S SUBMARINE ARSENAL
These midget subs have travelled far beyond the Korean coastline, but they didn't journey underwater. As Burlingame notes, "The submarines built by North Korea have also been sold to Iran."
Stephenson wonders: "Could an Iranian midget sub penetrate an American harbor?" If so, it could present a real danger, and in addition to getting their hands on several North Korean Yugos, the Iranians have also developed a powerful midget submarine of their own.

Military experts describe the Iranian Ghadir as silent enough to elude the most advanced U.S. sonar. As recently as June 2009, Iran commissioned three more Ghadir-class submarines, bringing the total number of these midget subs to seven. Like the North Korean Sang-O subs, the Ghadir subs are 50 percent longer than the Yugo, but still small enough to sneak into a harbor. And they're large enough to drop small teams of commandos onto enemy shores, damage warships, and lay underwater minefields. Iranian military sources have reported that, in addition to torpedoes, the Ghadir is also capable of launching missiles.
As is the case with North Korea, details surrounding Iran's midget sub-technology remains speculative. Still, Iranian officials claim that the subs are equipped with the latest military and technological hardware.
