They recently purchased Russia's new SS-N-22 Sunburn missiles.
They are considered the most accurate and deadliest missiles in existence.
Those who have witnessed its performance trials invariably come away stunned. According to one report, when the Iranian Defense Minister Ali Shamkhani visited Moscow in October 2001 he requested a test firing of the Sunburn, which the Russians were only too happy to arrange. So impressed was Ali Shamkhani that he placed an order for an undisclosed number of the missiles.
The Sunburn can deliver a 200-kiloton nuclear payload, or: a 750-pound conventional warhead, within a range of 100 miles, more than twice the range of the Exocet. The Sunburn combines a Mach 2.1 speed (two times the speed of sound) with a flight pattern that hugs the deck and includes “violent end maneuvers” to elude enemy defenses. The missile was specifically designed to defeat the US Aegis radar defense system. Should a US Navy Phalanx point defense somehow manage to detect an incoming Sunburn missile, the system has only seconds to calculate a fire solution –– not enough time to take out the intruding missile. The US Phalanx defense employs a six-barreled gun that fires 3,000 depleted-uranium rounds a minute, but the gun must have precise coordinates to destroy an intruder “just in time.”
The Sunburn’s combined supersonic speed and payload size produce tremendous kinetic energy on impact, with devastating consequences for ship and crew. A single one of these missiles can sink a large warship, yet costs considerably less than a fighter jet. Although the Navy has been phasing out the older Phalanx defense system, its replacement, known as the Rolling Action Missile (RAM) has never been tested against the weapon it seems destined to one day face in combat.
The Sunburn’s amazing accuracy was demonstrated not long ago in a live test staged at sea by the Chinese –– and observed by US spy planes. Not only did the Sunburn missile destroy the dummy target ship, it scored a perfect bull’s eye, hitting the crosshairs of a large “X” mounted on the ship’s bridge. The only word that does it justice, awesome, has become a cliché, hackneyed from hyperbolic excess.
