As for P-28 it is deja vu all over again we had the same discussion on its armament and capabilities 4 years ago

Apart from the fact that PLAN spends more money than Japan/India/Korea/Pakistan/East Asian navies combined, yes there is disparity in SSKs thanks to Scorpene. On FFGs P-17 is superior to 054 (CODOG vs CODAD, better air search radar and weaponry) but don't have numbers china has. On destroyer front, P-15A would be welcome addition and in size and armament will be bigger than anything china has right now incl Sovermenny.merlin wrote:India might be slow in building them ships but are they technologically inferior to Chinese ships? Yes, if you are smoking something strong.
Of course they spend a lot of money. They are transferring from brown water to blue water and they are building a damn number of all classes of ships. They build SSBNs and SSNs which Japan/India/Korea/Pakistan/East Asian do not and which cost a lot. They build DDGs and FFGs and LSDs and LSTs and tankers and replenishment ships and you just name it. There's no big surprise that a massive shipbuilding program costs a lot, isn't it?John wrote:Apart from the fact that PLAN spends more money than Japan/India/Korea/Pakistan/East Asian navies combined, yes there is disparity in SSKs thanks to Scorpene.

But still what about subs? Let's say it detects a sub 60 kilometers away, what weapon it'll use to hit that sub?Katare wrote:I think in P28 IN put all it's money in making a compact ultra low signature ship that will protect/escort major battle ships from lurking subs.

Luda and Jianghu although built in 70s and 80s were essentially 1950 vintage. 052C, 054A, 071 et al are not 20 years behind there time any more. China is rapidly narrowing the technology gap and sheer numbers will start to count if India will continue it's leisurely pace of naval shipbuilding.John wrote:SNaik,
Yes that is my point so comparing number of vessels when you spending that much is like US boasting about how many vessels they are building compared to Russia.
That said SSNs may not necessarily cost more than current generation SSKs, our Scorpene is great example of that. Also China was always about sheer numbers even 20 years ago they operated a fleet surface vessels far more numerous than IN so it is not something that changed in last decade, the rapid ship building was mainly to maintain number and to make up for 13 Luda and around 25 Jianghu's which will be retired in the coming years'.

The main anti-sub weapon on the P-28 is its medium ASW helicopter, such as the Sea King. It can fly 400km around the ship if need be. Besides a modern SSK/SSN are hard to detect very far. A ship may get some suspicious pings and will send its ASW helicopter to investigate further. The helo will drop sonbouys in a specific pattern around the area of interest to triangulate a SSK/SSN. Once triangulated, the helo will drop a light-weight torpedoe almost right on top of the submarine and from which there will be no escape at that close range.Manish_Sharma wrote:But still what about subs?

Surely you're not saying "if the RN did it, it MUST be correct!"? And while the Type 23s have no ASW strike weapons, they DO have 8x Harpoons. The P-28 has no AShMs either -and I've been consistently mentioning the lack of BOTH AShMs/ASW strike weapons.titash wrote:@ Manish_Sharma
It will use the embarked Sea King to deliver homing torpedoes at said submarine
The RN Type 23 also deploys the exact same long range weapons package - they came to that conclusion after years of deploying IKARA on the Leanders / HMS Bristol
I would be interested in knowing typical HMS / TAS detection ranges in the Arabian Sea/Bay of Bengal...probably no more than 5nm / 20nm respectively, which means that engagement ranges are going to be much shorter. In such a case, the RBU-6000, which is virtually useless if the forum discussions are to be believed, will be a very useful weapon...specially for SSKs lying quietly on the seabed
Open for discussion...
Just an idea of some of the challenges faced by the IN at the time of Petya induction. Note the solutions referred to: increased sonar range, RBUs and Heavy Torpedoes with range matching that of sonars!Global Security wrote: The Pakistan Navy's acquisition of "silent" Daphne class submarines made it unlikely that they could be detected on passive sonars. The vagaries of hydrology in the Arabian Sea favoured the submarine because the temperature layers in the sea refracted a ship's sonar transmissions. The range of the Daphne's class submarine's latest homing torpedoes exceeded by far the maximum detection range and the weapon range of the Navy's anti submarine frigates. There was, therefore, a pressing need for longer range sonars, longer range homing torpedoes, and variable depth/dunking sonar which could overcome hydrological constraints.
The last three Petyas KILTAN, KAVARATTI and KATCHALL commissioned in end 1969. The Russian Petyas which started arriving from 1968 onwards greatly increased anti submarine capability. Their medium range sonars had a maximum detection range of several thousand meters; their anti submarine rockets had a range of a few thousand metres and the range of their heavy, anti submarine, homing torpedoes matched that of their medium range sonars.
It will be foolish if Agosta does try to engage a P-28 it will give away its location and every ASW asset will coverage on it (with its 9 knot submerged speed it cannot exactly fire and scoot away like an SSN), In all likely it will be used in shipping lanes or mine harbors and key choke points. Detecting subs at ranges greater than 10nm is extremely unlikely one of the reasons ASROC like weapons have not been deployed much (even if you happen to detect a submarine and fire dozen of them chance of LWT torpedo finding a SSK running on batteries is extremely low), a helicopter with 500 Km operating radius and 200 Kmph speed is far more potent than ASROC.Jaeger wrote:Atlas Elektronik DM2A4 SeaHake which apparently (I have no official information other than Wiki, so apparently) has a 50km/50kt performance envelope and according to the Atlas Electronik link above is already integrated with Agosta 90B and according to Wiki is in use with the PN.
