Seraj-1 boat is based on Bladerunner. There is an exceptional story no how Iran could buy a bladerunner... The brief is like this:
Around 6 years ago, Iran buys a bladerunner with the help of a middle man in South Africa, then Iranian ship go there upload it and then heads to Iran... In Indian ocean US navy with the help of Israeli Mossad realize it that ship X has bladerunners as its load...but it was too late as it seems... Then they try to stop it in ocean... they even come as close as 500 meters to the ship warning it to stop... then when the ship reaches as close as 65 km to Iranian territories, Iranian IRCG navy scort team starts to escort it to Iranian waters and boom!
The Seraj-1 has 130 km/h top speed, it has Electro-Hydraulic stabilizers for its 107 mm weapon and a 12.7 mm heavy machine in front.... Seraj-1 is equipped with a 30 km radar + navigation and communication equipment... This all was an initial prototype...
The current under development version of Seraj will have come in two versions, a torpedo boat + remote control heavy machine and another version with cruise Missiles + RC heavy machine...both versions will have a new radar and electronics....
Its distinct form of hull and material of structure allows it to fell less in very high speeds and feel almost nothing in bad weather situations...
PS: Non of those 148 km/h and 203km/h boats are SERAJ... It is just to enlighten some Indians friends who are interested to know about this Seraj-1 boat...
