INS Arihant: News & Discussion
Re: INS Arihant: News & Discussion
Hope & pray it was a K4. Was there a NOTAM/NAVAREA?
Re: INS Arihant: News & Discussion
There was a report of a NOTAM for an experimental missile scheduled a couple of weeks ago.ArjunPandit wrote:was it K4 or K5?

People asked if it had happened.
Most likely the experimental missile part is on the regular missile flown.
So I would think it's a K4.

It was K15. K4 test is going to be soon, NOTAM is out.SSridhar wrote:Hope & pray it was a K4. Was there a NOTAM/NAVAREA?

Re: INS Arihant: News & Discussion
Looks like K4, not K15.
Re: INS Arihant: News & Discussion
Thats Yuri Dolgoruky launching 4 Bulavas back in 2018. Not K4 or anything

that is a stock image, mostly used as a filler.Thakur_B wrote:Looks like K4, not K15.
The actual footage/images of the Arihant launch will not come out so quickly.

https://twitter.com/ShivAroor/status/15 ... 9194772480 ---> Pretty sure the Indian nuke-capable missile launched from nuclear submarine INS Arihant today was a 750-km range K-15 Sagarika. The real big momma, the 4,000 km range K-4, is likely to be tested in the next couple of days.

^ Waiting for it. So, they had a mix of K-15s & K-4s in their tubes when they left Vizag.

Does K-15 Sagarika always fly Hypersonic cruise trajectory to yield 750-km range?Ankit Desai wrote: https://twitter.com/ShivAroor/status/15 ... 9194772480 ---> Pretty sure the Indian nuke-capable missile launched from nuclear submarine INS Arihant today was a 750-km range K-15 Sagarika.

Can it not fly Ballistic?
Or both Ballistic and hypersonic glide (on re entry)?

India's submarine fleet to get booster dose early next year
On the SSBN (nuclear-propelled submarines armed with nuclear-tipped ballistic missiles) front, the 6,000-tonne INS Arighat is also slated to be commissioned within the next few months.
When she joins INS Arihant, she will add some teeth to India's strategic deterrence posture by strengthening the country's weakest leg of the nuclear triad. Under the Rs 90,000 crore advanced technology vessel (ATV) project, two more 7,000-tonne SSBNs (currently called S-4 and S-4*) are under construction, with one of them being "launched into water" last year.
As of now, India however has just one operational SSBN in INS Arihant, armed only with short-range 750-km B-O5 or K-15 missiles.

Re: INS Arihant: News & Discussion
^ I am disappointed that the Arihant diving/helmsman station is looking all TFTA as in a western submarine and not at all SDRE with very long dark narrow corridors.

I do not think people on twitter understand the importance & implication of that single photo above (of the helmsman station).
This is the first photo of an helmsman station of any boomer (SSBN) in Asia and outside of the select few countries (US/UK/Fr/Russia).
And that helmsman station really looks TFTA.

https://x.com/VivekSi85847001/status/17 ... 18903?s=20 ---> The Silent Indian Democracy. Beautiful model of India's doomsday creator "INS Arighat" nuclear powered, nuclear ballistic missile submarine. It belongs to one of India's most secret projects ever. The Indian Navy has two such submarines in service & two more bigger in the making.

Re: INS Arihant: News & Discussion
All these pictures have been in circulation for years. Can you please add them to the first post in the thread?

https://x.com/GODOFPARADOXES/status/176 ... 69812?s=20 ---> Interesting SSBN models.
1. Cross-shape rudder/planes (center model has end plates on stabilizers)
2. Sail planes
3. Streamlined sail
4. Superstructure with higher % of blending
5. Silos (IMO 12) because aft will also have the reactor & machinery room
6. Bladed prop (center model)

Re: INS Arihant: News & Discussion
Google Earth shows two boats at Vizag. Presumably one of them - the partially covered and likely longer - is Aridhaman while either of Arihant and Arighat are out on patrol.

Deep Dive On India's Nuclear Submarines
Question: Where is SSN ?
Shiv Aroor: " .... what I can tell you for sure is that, the work has begun. The engineering team, the design team etc. have been moving in full speed since the project sectioned few years ago. And... the things are moving."

India to commission second nuclear submarine by end of 2024
excerpted
weapons and buildIndia's second nuclear-powered ballistic missile submarine (SSBN) will be commissioned in the next few months, Janes understands.
The vessel, which will be in service as INS Arighat once commissioned by end 2024, is going to be formally inducted almost seven years after it was launched.
According to Janes data, Arighat was launched in Visakhapatnam in November 2017. It has a length of 111.6 m, beam of 11 m, draught of 9.5 m, and a displacement of 6,000 tonnes.
Arighat is one of three SSBNs that have been launched by India. First-of-class INS Arihant was launched in July 2009 and commissioned in August 2016, while a third yet-to-be-named vessel was launched in November 2021.
Four large vertical launch system (VLS) tubes in the submarine carry these Sagarika SLBMs. Sagarika is a hybrid propulsion, two‐stage, solid‐propellant missile. The first stage lifts the missile to an altitude of about 4 km. The missile has a range of more than 700 km.
Arighat is built with Russian steel equivalent to US HY-80 grade. The submarine is divided into seven compartments, with main divisions for the propulsion and combat management systems, platform management centre, and the torpedo room.
Arighat also features a double hull, encompassing ballast tanks, two standby auxiliary engines, and a retractable thruster for emergency power and mobility.
