Agni-iv suc­cess­ful flight


DRDO de­vel­oped the 4,000-km range nu­clear ca­pa­ble bal­lis­tic mis­sile Agni-IV, was suc­cess­fully flight-tested re­cently from Wheeler’s Is­land in Odisha. This lon­grange mis­sile pro­pelled by composite rocket mo­tor tech­nol­ogy, was tested for its full ca­pa­bil­ity. The Agni-IV, launched from the road mo­bile launcher, reached the pre-de­fined tar­get in about 20 min­utes. The mis­sile equipped with state-of-the-art avion­ics, fifth-gen­er­a­tion on board com­puter and with dis­trib­uted ar­chi­tec­ture has the lat­est fea­tures to cor­rect and guide for in­flight dis­tur­bances.

The most ac­cu­rate ring laser gyro-based in­er­tial nav­i­ga­tion sys­tem (RINS) and sup­ported by highly re­li­able re­dun­dant mi­cro nav­i­ga­tion sys­tem (MINGS), en­sured the mis­sile reach the tar­get within two digit ac­cu­racy. The re-en­try heat shield with­stood tem­per­a­tures of more than 3,000 de­grees Cel­sius and made sure the avion­ics func­tion nor­mally with inside tem­per­a­ture less than 50 de­gree Cel­sius.

Dr Vi­jay Ku­mar Saraswat, Sci­en­tific Ad­viser to Rak­sha Mantri, Sec­re­tary Depart­ment of De­fence R&D and Di­rec­tor Gen­eral DRDO; Av­inash Chan­der, Pro­gramme Di­rec­tor Agni, DS & CC R&D (MSS) re­viewed the launch ac­tiv­i­ties. Tessy Thomas, Project Di­rec­tor Agni-IV led the team of sci­en­tists dur­ing the op­er­a­tion.
