I agree. Just to arrest the falling numbers, I would like to see three additional Scorpenes. Hopefully by the commissioning of the ninth Scorpene, the first P-75I will be on her way. I don't know how we could afford additional Scorpenes + 6 P75I boats. Perhaps the money is there.John wrote:I am not fan of Scorpene but at this point i would vote for just simply buying 4-6 more to keep production line active rather wait another decade for P-75I to see fruition. I would not mind buying a few Kilos' as well.

japan did bid the soryu class to australia and lost.
this is their chance for a quiet deal which is theirs to lose.
but with even the US2 in MRCA deal mode, I am not too sure.
probably some kind of scorpene2 or HDW will win this.

subs offer the chance of great VFM - a cheap $1 million torpedo could sink a $1 billion DDG and deny large areas of sea to anyone.
thats a 1:1000 ratio
no other weapon offers that level of stealth and potential VFM. and that 1 sub would tie down vast ASW resources. a lone terrorist can tie down a battalion of police on sentry and patrol duty.

OK! I can understand stored oxygen, but what happens to the carbon dioxide emitted by humans. An average human exhales 2.3 lbs of co2 in a day. So if there are 70 sailors and officers that is 161 lbs of co2 how is this disposed?John wrote:The whole idea of AIP is you don't run the engines and don't need to snorkel which as you highlighted can greatly increase your chance of being detected by not just exhaust but the snorkel can be detected by radar.

sometime in WW2 iirc the murican gato and balao class subs were the first to have AC. and being murican also the first to have ice cream machine in the wardroom. these two classes destroyed most of the IJN merchant fleet over course of few years, helped by lack of IJN attention to ASW.

Re: Indian Navy News & Discussion - 03 July 2018
Thats like saying couple lgbs costing few thousand dollars stopped from 2 billion stealth bomber can wipe out hanger full of planes or ships docked in the harbor, you need to factor in the cost of platform not it's ammunition. The Scorpene cost more than any other platform except for carriers to date and that's why IMO unmanned submarine will be the future. They can do the same job a lot cheaper and lack of crew means they can be much smaller and have better submerged range.Singha wrote:subs offer the chance of great VFM - a cheap $1 million torpedo could sink a $1 billion DDG and deny large areas of sea to anyone.

High end unmanned drones and ucavs are not cheaper or less conplex than manned
Scorpene high cost is related to infra buildup and licensing fees too... p75 willnot be cheaper unless we build 20

Re: Indian Navy News & Discussion - 03 July 2018
The RuN has gone beyond BMos with the 3000km range Kalibir missiles aboard its subs which ate fired from std. tubes which is why Russian Lada/ Amurs being built- and series construction has resumdd, aten't equipped with Yakhont but some of their surface vessels ar so equipped. We have yet to develop our own LRCM, Nirbhay has been delayed and doesn't have the range too.It isn't difficult putting in a VLS plug for BMos if we want it on the Amur.
Now one of the main reasons why the Lada/ Amur was not built in large numbef thus far wad because their AIP system was still in development, plus the higher priority of building nuclear subs asap.The USN want only N - subs because of their far greatef capability.The IN does not need the expensive Soryu class or conv.Barracuda which Oz is getting from DCNS/ Naval Group because we are wisely going to builc our own fleet of attack boats, at least 6 in a first series.
Russia has resumed Lada production because they're more capable of the legendary legacy Kilos, which even in their latest advanced avatar have a high crew number.
The Lada has about 16 to 20 less at least with greater automation. Late model Kilos being very cheap- arojnd only $300M fotr export at the rate of only two years to build have allowed the RuN to keep their numbers of subs healthy while spending hard moneh on their N -subs.The Kalibir missile is going to bd the std. lLRCM across the sub fleet.
John is quite right about UUVs.This is the future for the littorals and even mini-subs launched from N-subs to penetrate heavily defended ports and track enemy subs intruding into the IOR .

Re: Indian Navy News & Discussion - 03 July 2018
Yes, the Russians took 13 years to build one Lada class (with no VLS plug), but apparently adding a VLS plug on a 2000t submarine "isn't difficult". And this conclusion is based on the highly logical argument "But, but they showed a little model with a VLS plug once!"Philip wrote:It isn't difficult putting in a VLS plug for BMos if we want it on the Amur.

Re: Indian Navy News & Discussion - 03 July 2018
Imagine a scenario of a drone/mine that stays below the surface and anchored to the ocean floor. It has a battery/AIP and also generates and stores energy harvesting it from surface wave motion. Using this energy, it runs a passive sonar and when the enemy ship is detected, launches a light torpedo at it. You can impose a semi-permanent blockade with minimal cost, danger to own personnel.
A submarine could deploy these before a conflict starts, enable them when the conflict starts using an underwater acoustic modem, disable them after the war is over.
Coming soon to a port near you.
PS: India/DRDO has acoustic modems, light weight torpedoes, smart mine technology and unmanned submersibles.

This is beyond pathetic and sickening considering our GDP is growing at 7.5% every year and we have a $2.8 trillion economy. Our defense spend this year will be just 1.5% of GDP and the budget for the next financial year has actually shrunk 5% compared to last year on a realistic basis (Inflation and other factors).
Re: Indian Navy News & Discussion - 03 July 2018
Vips-ji, %of GDP is a narrow way of looking at defence spending. In absolute terms it has increased. IMO our military planning is completely protracted, we want to give the forces the iPhones of warfare while we have the capability of micromax's. Let us also consider that the health spending of india is just 1.15-1.5% of GDP while that of massa is 18% of GDP, WHO says it should be atleast 2.5% of GDP. Priorities matter. Revenue component in defence spending is huge post OROP. With NFU et all, it will just crush the further modernization if any.
In terms of defence modernization, we make Embraer as a poster boy of defence manufacturing while forgetting that the IAF wouldn't even look at turboprops as fighting machines (tucanos) if at all HAL produced them during that time. It is time to start working with micromax's than running after iPhones post brochure-itis. The micromax post learning will eventually turn out to be iphone is the support is given.
Finally a mango question I would ask, was the S400 the need of the hour for force projection? when there is hardly any SSBNs, frigates are being built at their own speed. WhAP is lying in some corner, naval heli's are stored in some proposal, MMRCA2.0 just another evergreening of a promise, do we really need the co-axial kamov's when we are good enough in LUH and ALH. Just shows, we want a lot of hi-tech things but priorities are missing. (btw forgot to mention that we also have our own BMD project running).

Re: Indian Navy News & Discussion - 03 July 2018
The 'clip ONs' to FAC are actually a great and cost effective solution. The minesweepers are going to act under Indian Air cover, as long as the sensor suite is great, why is a specialist one-task-only hull needed? Pretty much every program of the armed forces has a cost tag of X0,000 crores, when the need could be satisfied much cheaper by innovative and tech intensive solutions.
