High profile defence agreements, including a contract for acquiring second nuclear submarine and another for S-400 missile system, which is said to the most potent anti- ballistic shield of present times, are likely to be finalised during the annual defence dialogue between India and Russia to held in Moscow tomorrow. Defence Minister Manohar Parrikar will co-chair the annual meeting of Indo-Russian Inter Governmental Commission for Military and Technical Cooperation (IRIGC-MTC) with his Russian counterpart Sergei Shoigu. Mr Parrikar is in Moscow for a three-day official visit during which he would be giving final touches to the defence agreements totaling about 5 billion dollars, sources in the Defence Ministry said, indicating that the formal inking of the contracts will take place during Prime Minister Narendra Modi's visit to Russia at the end of year. The most surprising agenda of the IRIGC-MTC meeting is the possible agreement on S- 400 missile system, for which, according to sources, both sides were in secret talks for the past five-six months. "They (agreements) may not take final shape during my visit but wed like to prepare some of them for Prime Minister Narendra Modis visit to Russia in December for example, the project for joint production of Kamov Ka-226 helicopters. I hope to use my visit to have it inked when the Prime Minister arrives. Also the purchase of S-400 missile systems – We anticipate these projects to be coordinated by next month," Mr Parrikar told a Russian news agency, before embarking on his official visit. India aims at securing its sky and vital installations from the Chinese side as S-400 system is capable of detecting and neutralising a ballistic missile attack from 400 Km, but the interesting fact is that Beijing has already contracted for the same system earlier this year under the 3 billion dollar deal for six batteries of the system.
