Now here is a question.
...Iran has one of the biggest oil tanker companies in the world. So what prevents Iran ( a country the known for asymmetrical strategies) to use some of these oil tankers by putting up few CIWIS and ManPads on board for the elementary self defence and use the deck of these giant supper tankers as flight pads for UCAV or even recon UAVs and place them in sensitive locations ..I understand an oil tanker is slow but hey anything moving on water these days is slow for today's weapons systems so slow or slower makes no difference. Call this a poor man's aircraft carrier......on a second thought..may be the already done that..
....i need another shot of coffee!..
