India has put its first successful step in the arena of ballistic missile defence by conducting a successful but a surprise test of new interceptor missile in late November over the Bay of Bengal. This missile, named as AXO (Atmospheric Intercept System), was fired from the Wheeler Islands off Chandipur in Orissa. In fact, AXO is a modified version of Prithvi-II specially manufactured for this test. It intercepted another surface-to-surface Prithvi-II missile.
