@ Negi You make a good point sirjee...someone with insider/operational information from the 80s is best suited to answer that question; perhaps tsarkar or chetak @ Chetak Can you please elaborate sir? A lightweight desi radar set or a heavier imported one used by SeaKing/Kamov etc? And why was it fo...

@ Katare I believe that statement is not 400% correct. The IN refused the navalized Dhruv for several reasons: (1) no automatic-folding blades (2) vibration issues (apparently resolved, but the fix was IIRC never trialled on a naval version...they had given up on the platform by then) (3) poor paylo...

@ negi The product definition / design phase started in the early 80s where there wan't much money to go around, let alone for a customized product for a low volume customer like the IN. It made eminently more sense to make a helicopter that the IA and IAF would use in bulk (replacing the Chetaks &a...

@ rohitvats / Rahul M The Dhrun design was not meant to complete with the 10 ton SeaKing types in ASW (longer time on station, heavier sensor/weapons load, etc) The Chetak on the other hand (just like the Wasp) was a very barebones helicopter used to drop 2x LWT/Depth Charges and (probably) carried ...

@anand_sarkar MAD typically has a high false alarm rate due to seabed wrecks, etc and needs to be used in conjunction with SONAR to get a positive ID. But what you say makes sense...the IN has all of peacetime to generate a baseline map of shallow water MAD signatures. During wartime (one would assu...

Gents,
This is a pretty decent article re: shallow water ASW issues

Page 23 1st para details the challenges faced by the RN during 1982...I guess these among potential reasons why we retain the RBU-6000 launcher on new ships

@ tsarkar

Thank you sir, for taking the time to explain in detail

@ Aditya G, You hit the nail right on the head. Until you make the complete solution in-house, i.e. a desi AShM + desi radar/FCS + desi warship, you will always have a 'proprietary' solution forced down your throat with every platform. The beauty of the US solution lies in the flexibility/interopera...

(Contd...) Perhaps it comes down to a choice of operational philosophies. Possibly in the RN and IN, ASW ships are not meant to prosecute submarines by themselves; instead they are meant to operate in pairs, or in conjunction with maritime patrol aircraft, or as part of a task group, etc Rocket laun...

@ Jaeger I am definitely not saying that if the RN did it, it must be correct. Like all professional navies, they have made their own share of stupid decisions over the last 300 years My point was, the RN operated the IKARA from several ships after WWII. The Leanders used IKARA + Limbo + light Wasp ...

@ Prem Kumar

+1 to you. Should be within DRDO's current capabilities to add a nosecone with guidance and a booster stage to the TAL. Not sure why the IN hasn't pushed for it

@ 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 H...

One must remember that no other IN ship in service or on the drawing board carries a rocket launched torpedo weapon Even the backbone of the Royal Navy's ASW frigate fleet, the 4500 ton Type 23 carries only 2 triple 324 mm + 1x ASW Helicopter; no ASROC/IKARA type weapons Perhaps the P28 isn't all th...

@ Cybaru The idea of putting live torpedoes on an UAV is not new. The USN tried it in the 60s (The DASH gyrodyne was an integral part of the FRAM upgrade and could deliver two torpedoes up to 25 miles from the ship). The program was cut short due to low reliability of the electronics in those days W...

@ Cybaru 2 x NURAV with dipping SONAR seems like a good solution. If the naval satellite comes through, I don't think it should be limited to LOS operations. I am more concerned with the feasibility of deploying dipping SONAR from a unmanned platform (using surveillance radar and deploying sonobuoys...

@ Singha I agree that adding a second 10T helo makes a huge difference to ASW capabilities. However, this is only a 3000 ton hull. If I understand correctly, the experience of operating 2 Sea Kings from the 4000 ton Godavaris wasn't very pleasant altogether. They invariably carry 1 Sea king + 1 Chet...

On the topic of Urans amidships, note that there is a serious lack of surface opposition in the areas where these ships are expected to operate. We have plenty of destroyers/frigates/missile boats that carry a heavy AShM fit to sink the PN, attack Karachi, etc This corvette is designed to have a lon...

@ John Thanks for the info. It's exactly what I suspected btw, any ideas why the IN chose not to procure a rocket delivered torpedo weapon? Given our ASW focus since 1971 and the fact that every home grown 3000+ ton warship is designed with a 2 Sea King hangar, I find it somewhat surprising Is it be...

@ Singha: I believe there is still reasonable doubt as to whether the Kamortas will carry the Klub ASW missile. The pictures of models indicate torpedo tubes and RBU launchers, but the only long range ASW weapon is the on-board helicopter On a related note, does the IN even possess the Klub ASW miss...

@ Singha: I did some wiki searching. Turns out the Dornier 228 / Islander both have a MTOW of 6.5 tons. For these aircraft to become useful ASW/AShW assets, they will have to carry a weapons payload (depth charges/torpedos/AShM), a comprehensive sensor payload (MAD boom, surface search radar, and se...

Re: Singha I had thought of the same thing regarding the Alize a few weeks ago; interesting to see that quite a few of us think alike The reason in all probability is the maintenance footprint. The Alize were used in the 60s from the Vikrant. The light Alouette III helos (MATCH role) came a few year...

Can any of the gurus please elaborate on the differences in structure and purpose between the following types of amphibious assault ships? They all seem to have a well deck and a heli deck per wiki, so there is a bit of confusion as to what exactly we will be building... LHA: Landing Helicopter Assa...

Nikhil T, You are right...we cannot do with 6-8 old subs. We need a minimum of 20+ boats to maintain 10 at sea (one thing to note however, is that newer generation mechanical equipment tends to have higher availability/uptime...I expect a higher fraction of Scorpenes to be operational as compared to...

Thanks Rahul M :-) To be perfectly honest, the distance from Zhanjiang to Port Blair is approx 2000 nautical miles or 4000 miles round trip. A C* diesel electric submarine will either need a full fleet train / logistical support ships (aka easy targets) in the Bay of Bengal, or will need to operate ...

Hello everyone...my name is Titash. I am an ardent military fan (mostly IN & LCA), and have been following BR since the 1996-97 timeframe (yes...using a lynx text browser). I'm an early-morning-before-I-brush passive participant in BRF on a pretty much daily basis. I used to send across a few sc...
