SUC­CESS­FUL FLIGHT TRIAL OF ‘NIRBHAY’ SUB-SONIC CRUISE MIS­SILE

SP's LandForces - - NEWS IN BRIEF -

De­fence Re­search and Devel­op­ment Or­gan­i­sa­tion (DRDO) achieved yet an­other feat with the suc­cess­ful test flight of ‘NIRBHAY’ - In­dia’s first in­dige­nously de­signed and de­vel­oped Long Range Sub-Sonic Cruise Mis­sile which can be de­ployed from mul­ti­ple plat­forms. It was suc­cess­fully test fired from the In­te­grated Test Range (ITR), Chandipur, Odisha. The mis­sile has the ca­pa­bil­ity to loi­ter and cruise at 0.7 Mach, at al­ti­tudes as low as 100 m. The flight test achieved all the mis­sion ob­jec­tives com­pletely from lift-off till the fi­nal splash, boost­ing the con­fi­dence of all sci­en­tists as­so­ci­ated with the trial.

The mis­sile took-off in the pro­grammed man­ner and all crit­i­cal op­er­a­tions viz. launch phase, booster de­ploy­ment, engine start, wing de­ploy­ment and other op­er­a­tional pa­ram­e­ters demon­strated through au­ton­o­mous way point nav­i­ga­tion. The guid­ance, con­trol and nav­i­ga­tion sys­tem of the mis­sile is con­fig­ured around the in­dige­nously de­signed Ring Laser Gy­ro­scope (RLG) and MEMS based In­er­tial Nav­i­ga­tion Sys­tem (INS) along with GPS sys­tem. The mis­sile ma­jes­ti­cally cruised for a to­tal time du­ra­tion of 50 min­utes, achiev­ing the range of 647 km. The mis­sile was tracked with the help of ground based radars and other pa­ram­e­ters were mon­i­tored by in­dige­nous teleme­try sta­tions de­vel­oped by DRDO.
