Antony said that till January this year, around three billion rupees had been incurred on the development of the system. The country's Integrated Guided Missile Development Programme (IGMDP) has not been abandoned, but was near completion, he said. He went on to say that surface-to-surface missiles Agni and shorter range Prithvi have been successfully test fired and were in various stages of induction.
Akash missile has taken the maximum time to develop. But the recent spate of user trials of the missile had been accurate within the desired limits of lethality, Antony said.
