The ship version is in deployment which means it's fully tested.
There were reports of a sub-launched version is under development.

In June 2019, Bharat Dynamics Ltd (BDL) won another order for 70 Varunastra worth Rs. 1200 Crores. These were to equip both ships and submarines like Scorpene. The first Varunastra shipment was made by BDL on November 21, 2020.

The US has techs to operate in GPS-denied areas. Guaranteed. Have had it some time now. (Just BTW, "6th Gen" is ONLY about operating in INTENSE EW situations.)

The US can operate DEEP underground without GPS signals.

All we can say is that the US has not shared such techs in the UKR conflict.

Its not just about GPS denial, which can then be used to cue-in INS/terrain-mapping. Its also GPS-spoofing.

So, the software needs to be smart enough to know when its getting spoofed, by cross-referencing GPS inputs vs INS inputs. It should figure out when GPS is not reliable and switch to INS mode

I am sure there are a lot more such EW techniques

It'd be essential to perform missile tests where the accuracy is measured under extreme EW conditions. Have a Himashakti type system to jam the airwaves near the splashdown area (or midcourse). Not easy to do logistically, but ought to be done

I guess Pralay is a worthy successor to Prithivi.

Shouldn't Pralay be an option to CAS. We should develop "simpler" low cost version which can be build and given to IA in large large numbers as super long range artillery. Prahar would be more suitable for supplementing the conventional tube/rocket artillery.

How about an anti-ship version to defend our lands against PN/PLAF surface fleet ? (If they survive the first salvoes of Brahmos).

India successfully conducts night launch of new-generation Agni-prime ballistic missile off Odisha Coast
NEW DELI: India tested the new-generation Agni-Prime ballistic missile, with a 1,000-2000-km strike range, from the APJ Abdul Kalam Island off Odisha coast last night. This was the first pre-induction night launch conducted by the users after three successful developmental trials of the missile, validating the accuracy and reliability of the system. Range Instrumentation like Radar, Telemetry and Electro Optical Tracking Systems were deployed at different locations, including two down-range ships, at the terminal point to capture flight data covering the entire trajectory of the vehicle.
Senior officials from DRDO and Strategic Forces Command witnessed the successful flight-test, which has paved the way for induction of the system into the Armed Forces.

I was just asking a general question.

A technique against gps jammer is to lock on to the satellite signal and ignore jammer signal based on the emitter direction.
But I was thinking that the anti-GPS jamming could be effectively done by wide band brute force jamming methods similar to the huge SAP-14 jammers on SU-30 MKI so that even frequency hopping would not work. Is that true?

Also you endorsed Sumeet's post that terrain mapping is an option. I replied to him that other than Nirbhay variants no news of optics for it on high altitude flying missiles. Can you comment on it?

https://twitter.com/GODOFPARADOXES/stat ... 47840?s=20 ---> DRDO's Standoff Anti-Tank (SANT) missile integrated on Mi-35 for trials;

SANT launchers are of 3 types:
1. Single
2. Dual
3. Triple

In picture, single launcher is shown.

SANT features:
* Range > 10km
* MMW seeker
* LOBL & LOAL capability
* Top attack & direct attack
* 8kg Tandem Warhead

https://twitter.com/Firezstarter1/statu ... 56768?s=20 ---> Indian Brimstome, sooner this gets into service, is integrated on as many platforms as possible, the better. Fire & forget, hard to track for most armies and if put on IAFs fast jets, even better. Can complement Nag on dedicated anti-tank vehicles.

Has it been tested to +/-75 degrees.

Or on Everest. Or on Mariana trench.

If not, then it will not enter service.

But the Indian army will procure a missile for BMP with Max operating temp of 45 degree. In a catagory where the DRDO efforts conveniently don't fit.

There was NOTAM for a June 20-21st missile test in the Bay Of Bengal.
Some US Aircraft was spotted making the trip.
My guess would be a long range hypersonic missile test for US to send such assets while a summit is going on!

It should be acceptable. It has been tested underwater, below 200 feet of water

We did not hear much of Akash-1S after tests, so yes, it could be an early iteration or original name of Prime. Akash-NG seem to be a totally new design using dual pulse and not ramjets. Visually, the NG seem to be derived off the LRSAM project.

This order book looks good since it shows the older ramjet design must have been well received by IAF for base defense in a post Balakote type paki counter attack. A mix of NG and Prime would do some good mission kill at AtmaNirbhar cost

I think Akash 1S was Akash with RF seeker, Akash prime is with some modifications to make sure the Missiles work well in Cold High altitude locations.

ramana, yes. Akash-1S was the technology demonstrator to upgrade the existing Akash- Mk.1 stock with an indigenous RF seeker. AFAK, Akash-1S was renamed as Akash-1P and in July 2020 (the Ladakh faceoff with China timeframe) when it was deployed there.

India’s next major defence export | Indonesia will buy Brahmos missile - WION
India-based defence company BrahMos Aerospace expects to close a deal this year to sell Indonesia supersonic cruise missiles worth at least $200 million, as it looks to expand its presence in Southeast Asia. BrahMos Aerospace CEO Atul D. Rane said that it was in advanced discussions with Jakarta on a deal worth $200 million to $350 million under which it had offered to supply shore-based missiles and a version that can be mounted on warships.

I am not even sure if development trials are over for Astra Mk. II.

In December 2020, it was announced by DRDO officials that Astra Mk. II would be tested by May, 2022. In October 2022, the IAF released a video with Astra Mk.II being launched from a Su-30 MKI using ejector-launcher. Don't know if that was a development or a user trial.

Then, there is also the ducted-Ramjet missile (SFDR), whose successful development trials are also said to have been completed.

Meanwhile, the order book of Astra-Mk1 stands at a measly 248. After an infinite # of development and user tests, another infinite # of post-induction tests will happen, by which time they will close the book on Astra-Mk1 and say they are waiting for Mk-2 to arrive

https://twitter.com/GODOFPARADOXES/stat ... 46214?s=20 ---> DRDO SLCM (Submarine Launched Cruise Missile). Currently under development and will be encapsulated for launch from torpedo tubes of submarines. Then booster will propel it out of water and into air.

Two versions of SLCM
1. Anti Ship with RF seeker
2. Land Attack with EO seeker with DSMAC

I assume so. I always called it digital terrain / contour matching, but IAC I think that's what "DSMAC" means here.
