    The Indian Navy’s (IN’s) Directorate of Ship Production has issued a request for information (RfI) relating to six Next Generation Missile Vessels (NGMVs) under the ‘Buy (Indian)/Buy and Make (Indian)’ category of the Defence Procurement Policy (DPP) 2013.

    The RfI, issued in early February, aims to “finalise the specifications of the NGMVs to meet the Indian Navy’s requirements,” after which requests for proposal (RfPs) will be issued to selected vendors.

    The RfI stipulates that the IN only welcomes responses from vendors that meet certain “minimum qualifying criteria” including the key stipulation that it should be a shipyard that has built “vessel(s) of similar specifications”.

    Did a quick comparison with probable candidates from the existing world fleet to find the best mix as of now what i see is that our best bet is either a faster Steregushcy or SA'AR 72 type platform.

    Israel calls it corvette, we call it a missile boat and our corvettes are much larger!

    We make our own missile boats or patrol vessels don't we. Saryu class doesn't fit this? Or may be make next class of such warships in India. Pipavav or GSL can make them

    We are also buying SSNs. I reckon what you meant to ask was why are we buying missile boats at all?
    Because we need numbers and because we don't want to use a billion dollar +SSN for each small missile launching job. each SSN is going to cost us minimum five to six times what a missile boat will.

    We are not buying SSNs. We will be building them. It depends on the objective of the mission which decides whether it be launched from ship or submarine.

    Do we have supply ships and reloader vessels in sufficient numbers to support this many ships? I have not seen any recent RFI or RFP issued for induction of those vessels, nor any indigenous project.

    Both the Saryu and the Kamorta do not have any currently installed SSM or SAM system. Also they're both upto ten knots slower than desired. I guess we could look at redesigning them to fit the parameters required.
    PIPAVAV will probably push for a Sterugushcy derivative or a design from DCNS given their association with DCNS and the Russians.

    I don't think it will be difficult to install SAMs or SSMs on Saryu or Kamorta. We have Prithvi fired from OPVs

    Was just looking through some more data. The Malaysians seem to be building a stretched GOWIND 2500 that would fit our proposal as well.
    That said an Incheon class or Gepard class frigate fits this RFP well.

    Installing them while maintain stealth is the key.
    The naval Prithvi (Dhanush) was tested from the Sukanya class. This was done as a stopgap measure for a naval nuclear option until we got our SSBN working. There are no OPVs currently deployed with DHANUSH on board.

    The govt on July 20 2014 cleared a proposal to buy five more fleet support ships. The RFP for the same is open to public and private yards.
    Incidentally this was among the first items cleared by the hon'ble FM in the first ever defence acquisition council meet.

    It would still need extensive redesign to do the same while maintaining stealth characteristics.
    You simply cannot bolt a club B container onto the deck and retain stealth.

    Off course. Like a Sukanya-A or something which takes care of all that. But it's not a bad idea to saturate the Arabian Sea & BoB with these small ships with some deadly weapons

    We need at least a hundred with a flotilla of twenty each on each coast.
    Now imagine if even half the twenty on the konkan coast are carrying eight nirbhay each.Our boys can hit Karachi and gwadar in the morning and celebrate the kills at Goa less than an hour later.
    Also imagine that we let it slip that at least five boats on either coast is carrying nuclear tipped LACMs. That would be a massive detterent to the Chinese and the Pakistanis.
