INS Vikramaditya Undergoing Refit with Barak-1 missiles, CIWS

LR-SAM at Aero India 2011

INS  Vikramaditya is undergoing minor ‘refit’ at its home base, Karwar, south of Goa. The refit would equip the ship with Barak-1 missile and 4 Russian origin but made in India Kashtan AK-630 Close-In Warfare System (CIWS). [via TOITribune India]

The Barak-1 missile system is being stripped away from the frigate INS Godavari which is due to be decommissioned. Godavari is 32-year old and got its Barak-1 CIWS 10 years back.

In a subsequent refit, INS Vikramaditya will also equipped with the LR-SAM medium range Point Defense Missile System (PDMS).

For the PDMS, the option was between LR-SAM and Russian Shtil missiles. Now that the LR-SAM has been successfully developed, it will the natural choice.

The Shtil system is the naval variant of Buk missile system that reportedly downed Malaysia Airlines flight MH17 over eastern Ukraine in 2014. It's currently fitted on IN Delhi-class destroyers and Talwar-class frigates.

Installing LR-SAM would entail some cutting through the deck, which would require four to nine months.

INS Vikramaditya would carry up to 32 or 48 LR-SAMs.

Astounding Rafale Performance Detailed

Rafale at Aero India 2015
Indian Defense Minister Manohar Parrikar briefed the press on the Rafale deal on April 13, 2015. During the course of his brief and a subsequent interview with NDTV, Parrikar revealed the following important details about Rafale's performance.

  1. Rafale can carry twice the payload (24 tonnes)  as the Tejas (10-12 tonnes).
  2. Rafale's 1000-km combat radius far exceed the 300-450 km combat radius of existing IAF aircraft.
  3. Rafale has a greater loiter time than any other Indian fighter.
  4. Rafale's weapons are superior to those of competing aircraft. 
  5. Rafale is equipped to penetrate heavily contested airspace without the need for  Suppression of Enemy Air Defences (SEAD) platforms. 

Rafale's integrated defensive-aids system named SPECTRA, developed as a joint venture between Thales and MBDA, protects the aircraft against airborne and ground threats. It features several methods of detection, jamming, and decoying and can be quickly reprogrammed to address new threats and incorporate additional sub-systems in the future.

During Operations over Libya, French Rafales reportedly operated independently of SEAD platforms.

Rafale vs Su-30MKI

The following are some of the features in which Rafale scores over the IAF's venerable Su-30MKI

  1. Rafale is designed for reduced radar cross-section (RCS) and IR signature, though it does not feature all aspect stealth. The aircraft's stealthy features include reduced size of the tail-fin, fuselage shaping, under-wing air intake positioning, extensive use of composites, and serrated patterns for the construction of the trailing edges of the wings and canards. Many RCS reduction features are classified. 
  2. Sensor fusion facilitates single pilot operations and more efficient use of weapons. 
  3. Better WVR combat performance during initial (first 40-s) engagement.
  4. Better range and loiter.
