INAS 323 commissioned at Goa as first unit of indigenously built ALH MK III enters Naval Service

Indian Naval Air Squadron (INAS) 323, the first unit of the indigenously built ALH Mk III aircraft, was commissioned into the Indian Navy in the presence of Hon’ble Raksha Rajya Mantri Shri Shripad Naik and Vice Admiral R Hari Kumar, Flag Officer Commanding-in-Chief of Western Naval Command, at INS Hansa, Goa on 19 Apr 21. Addressing the gathering, Hon’ble Raksha Rajya Mantri said that the commissioning of INAS 323 marked yet another milestone in the efforts towards enhancing maritime security and safeguarding maritime interests of the nation, as also embodying the spirit of Atma Nirbhar Bharat.


The squadron will operate three state-of-the-art ALH Mk III, a multirole helicopter with Shakti engine manufactured by Hindustan Aeronautics Limited (HAL). The Mk III version of the ALH has an all glass cockpit and will be used for Search and Rescue, Special Operations and Coastal Surveillance. 16 aircraft are under procurement and the aircraft are being delivered in a phased manner to the Indian Navy.


INAS 323 is commanded by Cdr Samik Nundy, an accomplished and experienced ALH pilot with extensive operational experience.

Indian Navy’s Nuclear-Powered Attack Submarine Project Before CCS For Approval, To Be Prioritised Over Second Indigenous Aircraft Carrier
Indian Navy’s project to build nuclear-powered attack submarines (SSNs) is before the Cabinet Committee on Security (CCS) for approval, a report in the Indian Today says.

The programme, which involves the design and construction of six SSNs, each displacing around 6,000 tonnes, is likely to put the Indian Navy’s plan to build a 65,000-tonne indigenous aircraft carrier on the back burner.

SSNs will make the Indian Navy’s submarine arm stealthier. Unlike diesel-electric submarines, SSNs can remain underwater almost indefinitely.

Why we are looking at a decade timeline when we have arihant design , kalvari experience , we can do it faster if we want ?

Why we are looking at a decade timeline when we have arihant design , kalvari experience , we can do it faster if we want ?

The government gave the go ahead for the SSN project in 2015. Design work had begun at the Gurgaon-based Submarine Design Centre sometime around 2017 and considerable progress has been made since. The design is likely to be finalised in the next two years and the fabrication of the hull will begin after that.

The reactor being developed for the SSN project would be a vast improvement over the one used on Arihant class boats. It is believed to have an output of around 190 MW, a major upgrade over the 83 MW reactor on Arihant-class SSBNs.

India is also working on a new type of SSBN, identified as S-5. This new type will be a significant improvement over the Arihant-class. It will have a displacement of 13,500 tonnes and will be capable of carrying 12 long-range nuclear-tipped missiles.

The answer is in improvements, indigenisation and upgrades

Why would a 6000 ton submarine require 190 MW reactor, when Arihant of similar weight class requires only 83 MW..
If the news regarding 190 MW powering future SSN and SSBN (S5 class) fleet is true then both will have similar displacement of around 13500 tons.

I tried to do some research , so i think we don't know whether s4 and s 4* are launched or in construction , maybe last one in construction , and the level of secrecy in it is high , so s5 is going to be began construction soon , and reactor of s 5 and ssn will most likely similar with later getting more energy dense one , also arihant got a good hull but not best for ssn , so the design part on it is going , the pumpjet for it is also in development , also a electric motor propulsion for 3000 ton class was in tendering , maybe we may get a advanced variant in it , we have kalvari experience , which may help in attack submarine aspect different from ssbn.

Also france took 14 yesrs to launch first barracuda ,cause their older design was smaller and much compact , we may have enough space liberty in arihant design

Ssbn are sloth , ssn are velociraptor , they require almost double power compared to their ssbn counterpart ,@shuvo@y2k10

Why does every Naval project takes 5-8 years just to freeze the design? Then Construction takes same to almost twice the time!

Why is amca took almost close to a Decade to freeze the design ?

Why is amca took almost close to a Decade to freeze the design ?

Please ask this to the agency which took this much time. My question if for both.

For comparison the latest Yasen class SSN from Russia has a submerged weight of 13800 tons and are powered by 200 MW class OK-650KPM reactor.

That's a ssgn , not ssn , ssgn as re modified ssbn for carrying cruise missiles in vls .

SSGN, SSN, SSBN are NATO designations which Russians do not strictly follow.

The Yassen class carries only Oniks or Kaliber class anti-ship cruise missiles. It's submerged speed of around 25-30 knots is similar to that of american Virginia class SSN.

What about manuverability , what about sensor , how any hydrophones it will buzz up at that speed , also that's submerged displacement .

Okay it can travel fast but can it manuver , can it turn around fast , also i have reservations that Russian might be under stating it's speed

25 to 30 knots is the 80 to 90 percentile speed limit for these things as most things they track fall in that range like carriers or fleets and also there is max speed under extreme measures. Russian subs are typically double hull or used to be and therefore dive to greater depths. Most data is secretive and not in public.....at best 60% believable any open data.
