The Iranian naval threat. '... Meanwhile, the Iranians keep improving the firepower of their fast patrol boats and adapt Western technology to further raise the threat level. They now have a semi-submersible fast patrol boat they acquired from North Korea and improved. This carries significant firepower and is hard to find and hit. They have taken British technology from the superfast Bladerunner speedboat and turned it into the Seraj-1, which exceeds 55 knots on the surface. A newer version, thought to be the Seraj-2, may reach 80 to 85 knots, far faster than anything in the U.S. inventory. And the Iranians appear able to acquire diesel engines, surface drives and other sophisticated gear from Western sources without any practical interference.'
200 yards is too close. '“Too close” has to be publicly defined. The Iranians should be put on notice that if they close to within 500 yards of any ship or boat, they will be fired on, not just given the courtesy of warning shots. Five hundred yards is about the range of a rocket-propelled grenade (though it’s hard to hit anything smaller than a large ship from that distance).'
