India on Thursday propelled itself into an elite club of nations with Inter-Continental Ballistic Missile (ICBM) technology by successfully test-firing nuclear-capable Agni-V, which covered a range of more than 5,000 km. The significance of the success lies in the fact that Agni-V is the most formidable missile in India's arsenal, with the longest range. With this grand success, India joins the U.S., Russia, France and China, which have ICBM capability.
