Iran has tested an advanced high-speed torpedo in the Strait of Hormuz. The test is not only a provocation, but the torpedo is also a new threat to vessels in the international choke point.
According to a report by FoxNews.com, the torpedo in question is called the Hoot, and appears to be a variant of the Russian Shkval, a rocket-powered torpedo capable of reaching speeds of 250 miles per hour, with a range of six miles. This torpedo could cover that distance in about a minute and a half.

According to GlobalSecurity.org, Russia designed the Shkval as a "revenge weapon" for use by submarines to take out a ship or submarine that fired on them. The original Shkval was tipped with a nuclear warhead. The 16th Edition of Combat Fleets of the World notes that an export version has about a 450-pound high-explosive warhead. Combat Fleets reported Iran was developing a variant of the Shkval known as the Dalaam.
The torpedo is a particular threat given the confined nature of the Strait of Hormuz, which is as narrow as 21 nautical miles.
The Shkval can be fired from any 21-inch torpedo tube — which means that the entire Iranian submarine force, three Kilo-class submarines and at least 16 Ghadir-class minsubs based on a North Korean design, plus another class of minisub called the Qa'em, can use this weapon.

Iran has engaged in a number of provocations in recent months, including harassment of the Arleigh Burke-class guided missile destroyer USS Mahan (DDG 72) in April and close encounters with the missile-range instrumentation ship USNS Invincible (T AGM 24).
Iran also has handed off advanced weapons like the Noor anti-ship missile to various rebel and terrorist groups — and some of those missiles were subsequently used in attacks, notably against an Israeli corvette in 2006 and multiple attacks on the guided-missile destroyer USS Mason (DDG 87) last year.
