Aksha,
1. I am not against Russian quality, but the Amur class submarines are still only on paper. They were developed from the Lada class which had serious defects [Even Russian did not induct them into service].
2. Another problem is the AIP. Russian AIP is totally untested, its performance is unknown and it is their first ever attempt to develop such a system. Fact is the Russians are developing a totally new AIP for their new submarines which raises more doubt about the AIP's performance.
3. Why buy Amur ? Why not the improved Kilo class submarines which are already being produced for various customers including the Russian Navy ? These are already in production, will cost less, will be delivered fast.
besides i will add some of my own opinions as to why amur was chosen amon the subs participating p75i
1)amur is the only sub that can launch bramhos,vls mode
2)scorpene is too small for bramhos vls,the french themselves agreed and they said they will offer a much larger scorpene,but it is stil on paper.
3)all the competitors agreed that it is not possible for a deisel sub to have both bramhos and aip.the sub becomes too big,less maneuverable and speed decreases.
4)as for the spanish s80

who wants a submarine that cant resurface after it has dived,only the taliban will have interest in it ,if india waits around for the spanish to fix its overweight problems ,well it will be too late to rescue its underwater forces.
5)german type 216(
please note that its the type 216 that's offered and not the type 214) faces same problem as scorpene(too small,increase in size needed,hence again only on paper) ,cant load bramhos.
6)amur on the other hand can load bramhos vls(i hear that it was made with vls klubs in mind) as well as aip(but not at the same time).@tako as for your worries about aip ,
Fincantieri has offered in partnership with russia their aip system,wire guided black shark torpedoes are also offered ,something not seen in previous russian subs,making them much more dangerous
6) as for soryu class if RFI was issued to japan ,then japan didnt answer it.
i think you people are just too biased towards the amur sub,i know there has been accident on kilos in the indian navy ,but we know quite well that its not the kilo's fault ,all these accidents were caused by mishandling or unproper refits,
hell even the iranian navy hadn't had accidents on the kilos.
@ takoyou were saying about the defects of the amur class sub
the know that all the subs in p75i are only on paper(all of them needs an increase in size to accomodate a vls bramhos) except the amur (lada class)the amur is closest to production.
project 75i,it is compulsary that at least half of theses subs have bramhos vls.(scorpene ,type 216 ,s80 cant without increasing their size)only the russians can fulfill these needs faster,(scorpenes ,type 216 too small,s80 cant resurface),and i heard from a friend in the navy that the
iribris reconstruction/leasing deal might depend on project75i.
so if you have read what i have posted ,you will see it was just cold logic,not action of lobbyists
but again this deal may or may not be attached to the project 75 i deal as for the kilos i bet the weapon illiterate indian media will skin the navy alive if they buy them after those accidents,and again they cannot carry bramhos.
