The Islamic Republic of Iran has successfully test-launched its new deterrent missile, Sejjil 2, pushing forward its long-term defense program. The 2000-km-range surface-to-surface missile was launched in the central Iranian province of Semnan on Wednesday. Unlike Iran's Shahab 3 missile, which burns a liquid, the new Sejjil 2 model is solid-fueled. This characteristic gives the missile greater deterrence power as it lowers the time needed to prepare for launch. Sejjil 2, first tested eight months ago, is also more accurate than the Shahab 3. In comments made days before the launch of Sejjil 2, President Mahmoud Ahmadinejad said that the missile was produced in line with Tehran's "deterrence policy". "Our progress in this field is solely aimed at establishing peace and stability in the region. This technology will only be used against an enemy with ill intentions," he explained.
