ABOUT NASAMS-II AIR DEFERENCE SYSTEM
It is upgraded version of NASAMS developed by Raytheon in partnership with KONGSBERG Defence and Aerospace of Norway.
It has been operational since 2007.
It has new 12 missile launchers coupled with 3D mobile surveillance radars for quicker reaction.
It is highly adaptable mid-range solution for any operational air defence requirement.
It provides tailorable, state-of-the-art defence system by enhancing ability to quickly identify, engage and destroy current and evolving enemy aircraft, emerging cruise missile threats or UAVs.
It incorporates 3D Sentinel radars, short and medium-range missiles, fire- distribution centers, launchers and command-and- control units to quickly detect, track and shoot down multiple airborne threats. It is currently used as part of US’s air defence network for guarding capital city Washington DC.
It also has been deployed in several NATO countries.
WHY IS INDIA BUYING NASAMS 2 FROM THE U.S. WHILE WE ARE ALREADY GETTING S-400 FROM RUSSIA?
Because India needs multi-layer defence in order to protect large cities
MULTI-LAYERED AIR DEFENCE SHIELD
The NASAMS II will form part of the overall air defence systems of the country which will include the S 400 Triumf air from Russia and the Indo-Israel joint venture product Barak-8 medium range surface to air missile.
An Indo-Israeli surface-to-air missile (SAM), designed to defend against any type of airborne threat including aircraft, helicopters, anti-ship missiles, and UAVs as well as ballistic missiles, cruise missiles and combat jets.
The outermost layer of Delhi’s missile shield, in turn, will be provided by the indigenous two-tier ballistic missile defence (BMD) system being developed by DRDO.
This system’s AAD (advanced air defence) and PAD (Prithvi air defence) interceptor missiles
