Iran's Super Torpedo

This is being reported by the NYT, and should be taken seriously, I think:

Iran said Sunday that it had test-fired what it described as a sonar-evading underwater missile just two days after it announced that it had fired a new missile that could carry multiple warheads and evade radar systems.
The new missile is among the world's fastest and can outpace an enemy warship, Gen. Ali Fadavi of the country's elite Revolutionary Guards told state television.
General Fadavi said only one other country, Russia, had a missile that moved underwater as fast as the Iranian one, which he said had a speed of about 225 miles per hour. State television showed what it described as the missile being fired.

This is the deadly Russian Shkval, which is said to have been purchased by China for their under-sea fleet.
