Iranian President Mahmoud Ahmadinejad has unveiled the country's first domestically-built long-range unmanned bomber. The four-metre long plane, dubbed Karrar or striker, was inaugurated by Ahmadinejad on Sunday, the national day for the country's defence industry. Iran has been producing its own light, unmanned surveillance aircraft since the late 1980s. Since 1992, Iran has also produced its own tanks, armored personnel carriers, missiles, torpedoes and a fighter plane. Iran began an arms development program during its 1980-88 war with Iraq to compensate for a US weapons embargo.
