In­dian coastal sur­veil­lance and IAI-Elta


The In­dian Navy has ac­quired two air­borne radars de­vel­oped by Is­raeli IAI’s Elta Sys­tems Group to fill vi­tal gaps in the coun­try’s coastal se­cu­rity sys­tem. This ac­qui­si­tion has fa­cil­i­tated sur­veil­lance through bal­loon-mounted air de­fence radars with de­tec­tion range of over 500 km, in­clud­ing track­ing of low-fly­ing air­craft.

The In­dian Navy has ac­quired from Is­rael two EL/M-2083 Aero­stat air-search radars, which are al­ready in ser­vice with the In­dian Air Force. While the ac­qui­si­tion was on In­dian Navy’s shop­ping list for a long time, it was ac­cel­er­ated by the gov­ern­ment af­ter the Mum­bai 26/11 ter­ror­ist at­tack.

The new radars, mounted on a hot-air bal­loon se­cured to the ground have im­proved the In­dian Navy’s abil­ity to de­tect en­emy air­craft by pro­vid­ing 3D cov­er­age over a ra­dius of 500 km. The big­gest ad­van­tage of Aero­stat radar is that it is not fixed and can be moved to any lo­ca­tion on the ba­sis of pre­vail­ing threat sce­nario. It is de­signed to pro­vide flex­i­bil­ity in op­er­a­tional de­ploy­ment, thus adding new di­men­sion to the coastal sur­veil­lance.

An­other sys­tem of this kind is the Teth­ered Aero­stat Radar Sys­tem. It is an early warn­ing and con­trol phased ar­ray radar de­signed to de­tect ap­proach­ing hos­tile air­craft from long ranges, es­pe­cially at the low al­ti­tudes. Data gath­ered by the radar is trans­mit­ted to a cen­tral air de­fence com­mand and con­trol cen­tre where it is used to main­tain an ex­tended com­pre­hen­sive air situation pic­ture. Once a po­ten­tial threat is de­tected the on-board sys­tem alerts re­spon­ders in a timely man­ner. It is based on the EL/M-2080.
