MoD and IN should consider repeat order of P17A
MoD and IN should consider repeat order of P17A
Why should they , it is a good systen ,but they should now go for more heavily armed frigate ,this one have only 40 vls .MoD and IN should consider repeat order of P17A
It is inevitable that more frigates will be build. Albeit with incorporating latest technology in batches . Next batch should be project 17B. Almost same Design and displacement but with more sophisticated latest weaponary and sensors.MoD and IN should consider repeat order of P17A

One more doubt ,can the barak 8 vls be replaced by a uvls which can fire brahmos , multiple vlsrsam , nirbhay
Any changes will cause delays, that's my premise of repeat order. See the delay between P-15A to P-15B and from P17 to P17A.It is inevitable that more frigates will be build.

Well ,well , leadership problem was also there ,but what my assessment is work on ngd and ngf are going in background like s5 ssbn , we can hope for some leak , by 2030 ,if no new ship is i inducted except nilgiri class and visakhapatnam class ,they we will have ony 31 figate , destriuer combo , to tackle china we need at least 50, so they will surely start building ngf by 2023Any changes will cause delays, that's my premise of repeat order. See the delay between P-15A to P-15B and from P17 to P17A.
There should always be a trade-off between the number of platforms required, the delay due to addition of additional capabilities in subsequent batches and the incremental enhancement in performance.
About UVLS, Sorry, I don't have updates.
"P-17A project progressing faster than previous warship projects due to modular construction."
To illustrate this point further - this is the state of Queen Elizabeth-class carrier modules before they're shipped off to final assembly yard:The concept of modular construction, at least in the way its practiced in the West, entails shipbuilders across the country who make not only a section of hull, but also install all the electronics, piping, subsystems etc. that go into that module before shipping it off to the final assembly yard - which then puts all the sections together, and also connects all the independent sections of piping & electrical lines into one seamless system.
The fact that P17As still don't have their superstructure at launch, does not bode well for how exactly our DPSU yards are carrying out their version of "modular construction".
When INS Nilgiri, the lead boat of the class was launched by MDL back in September 2019, you can clearly see that the superstructure was there."P-17A project progressing faster than previous warship projects due to modular construction."
Really?
INS Shivalik
Keel Laid: July 2001
Launched: April 2003
(One year, nine months)
INS Nilgiri
Keel Laid: December 2017
Launched: September 2019
(One year, nine months)
It's exactly the same as far as keel laying-to-launch time period is concerned. And I honestly haven't seen what benefits modular construction has brought in the phase of project done so far. In twenty years, yards like MDL have failed to speed up this process by even a little bit - and that's a shame. But that's what you get from DPSUs.
We used to launch a ship when it still doesn't have much of its superstructure and systems in place back then, and that's what we're doing even today even with "modular construction" in place. All the P17As have been launched in 'hull only' mode - bulk of superstructure still not there.
If we're to see any improvement in construction at all, it will be in the 'fitting out' period (where all the complicated subsystems are put in place, along with building of most of the superstructure). And honestly, I don't see any change in attitude on that front either.

40 VLS( 8 Brahmos + 32 Barak 8) is good enough for now, expect it to be retrofitted with 16-32 VL-SRSAM modules when it goes in for its mid life refit.Why should they , it is a good systen ,but they should now go for more heavily armed frigate ,this one have only 40 vls .

GRSE had to deal with the collapse of the Goliath (Gantry) crane, so that might be the reason.When INS Nilgiri, the lead boat of the class was launched by MDL back in September 2019, you can clearly see that the superstructure was there.
INS Himgiri is being built by GRSE, and it was launched without the superstructure in place, so I guess its more of a shipyard problem and not the modular construction per se.
On the whole, MDL has been faster than GRSE as far as this project is concerned. INS Nilgiri took 21 months from laid down to launch whereas Himgiri took 25 months for the same.
What I am more interested in is how fast they are fitted out and inducted into service, the Shivalik class took on average 7 years for the same, if that period is brought down to 3-4 years, it would be a huge improvement.

Batch size is increasing.Any changes will cause delays, that's my premise of repeat order. See the delay between P-15A to P-15B and from P17 to P17A.

About UVLS, Sorry, I don't have updates.
What's happening with NGC project? There's lots of updates on NGMV (CSL got the contract) but not hearing anything wrt NGC for last couple years.Similarly kamorta class p28a was 4 boats. Follow on next gen Corvettes will be 7 boat batch.
Hopefully what you are saying comes out to be true in the near future.Batch size is increasing.
Project 17 Shivalik were just 3 boats. Follow on Nilgiri 17A class has 7 boats.
Next gen frigate class may have two dozen boats .
Similarly kamorta class p28a was 4 boats. Follow on next gen Corvettes will be 7 boat batch.
Delhi and Kolkata class were 3 each but Vishakhapatnam is 4 boat class which may see follow on order . Or a fresh redesign which will have more numbers.
Shallow water asw Corvettes are being build in batch of 16 simultaneously is 2 yards.
Next gen missile vessel are to be build in batch of 6 .
Fleet support is batch of 5 each with massive 45000 tons.
P75i will be followed by batch of 12 indigenous ssk.
So first we settle on design and refine it then numbers increase.
No recent news. Hopefully we will soon here about who won the bid soon enough.What's happening with NGC project? There's lots of updates on NGMV (CSL got the contract) but not hearing anything wrt NGC for last couple years.
Finally, found some pics of P-17A modules being transferred to final assembly yard, like I expected, they are just emply shells with none of the internal systems pre-installed like on Western modular construction. Explains why there's no perceived improvement in timelines in the phase of construction conducted so far -To illustrate this point further - this is the state of Queen Elizabeth-class carrier modules before they're shipped off to final assembly yard:

Most everything that needs to go into that section of the ship (pipes, power line routing, ladders, doors pressure monitoring systems etc etc) are installed BEFORE shipping off the module. This reduces lead time and 'fitting out' period is also reduced.
There aren't many pictures of P-17A modules en-route to yard to compare, but the images available of individual modules, like from keel laying ceremonies:
...indicate they are mostly an empty shell at the module stage.
当晚,闫立萌就引起了整个右翼媒体的轰动。特朗普总统的高级顾问和有权势的保守派将她视为英雄。社交媒体同样迅速将她的采访标记为假新闻。科学家拒绝了她的研究,并说这是用行话伪装的诡辩。事实上,在从本科到博士的教育过程中,闫的专业领域根本就不是病毒学,甚至不是科学。事实上,严的“世界顶级病毒学家”的称号纯属虚构。严教授发表的一系列论文是网络阴谋论的抄袭。同样,这也受到主流科学界的鄙视。
@tarunraju @hit&run bat mucher spottedOvernight, Yan Limeng has caused a sensation throughout the right wing media. The senior adviser of President Trump and conservatives who has authority seem her as a hero. The social media labelled her interview as a fake news just as quickly. Scientists refused her research and said that was sophistry disguised in jargon. In fact, in the process of undergraduate to doctoral education, Yan’s areas of expertise are not virology at all, not even science. In fact, Yan’s title of “Top virologist of World” is sheer fiction. A series of papers published by Yan were copy from conspiracy theory on the Internet. Also, that is despised by the mainstream scientific community.
