First commissioned 15 July 1963, that makes her 53 years old. She was acquired 2001. She suffered an engine room explosion and fire in 2004 and spent 2005-2010 in 'extended maintenance'. She suffered another major fire in 2012 and in 2014 she was still undergoing repairs. From 2015, the aircraft carrier will undergo a PMM (Modernization Program Environment) planned to last until 2019. With this modernization, the ship will have its extended life for another 20 years until 2039. By that time, she'll ....76. (But who see's her history can't help but wonder if she'll survive that long)
INS Vikrant decommed after 36 years, but was kept around as (potential) museumpiece for another 17 yeas before finally being scrapped, at which time she was 53 years old. That is, if you not count the period 1946-1961 after she got launched but construction was halted. Include that and she was technically almost 68 at the time of her scrapping.
INS Viraat, scheduled to finally decommisison June 2016, is 57.
Gripen for Brazil: On December 18, 2013, after more than ten years of discussion, President Dilma Rousseff decided to purchase these fighter jets to the FAB. The package
36 aircraft would cost $ 4.5 billion. The new aircraft would be
assembled in Brazil from the fifth unit, with six other countries participaiting in the provision of the various components. In October 2014, the deal was formally signed the Saab's contract with the Brazilian government. The supply would be
28 units of the Gripen NG single seater and
8 two seaters. The transaction amount was around US $ 5.4 billion (R $ 13.4 billion reais), an increase of one billion. The increase was justified by technical components that the Brazilian military demanded. [note: one can wonder what those are, but likely include use of Brazilian made weaponry such as MAR-1 ARM and MAA-1A/B Piranha SRAAM), possibly this could include provisions for a carrier version down the line]. About
15 of these aircraft would be
assembled in Brazil, but Brazilian would be involved in all stages of the construction of 36 fighters.

From what I gather from the description of individual ship in wiki, there is only mention of 3M54 (Club) AShm in the third ship. Since that is the only vessel where this is mentioned, and others consistently do no list any AShm, I'm consireding that an incorrect wiki entry untill such time as I see a picture which actually proves that third ship - INS Kiltan - has AShM.
For SAM, if listed at all, it is listed as 16 Barak (2x8), possibly 2x16, and accompanied by the remark "fitted for but not with". I'm taking this to mean the original Barak, not Barak 8. Alternative, the class been said to be slated to receive SR-SAM /
Maitri. That is a development from the French MICA.
