Where did you get that ? I thought the 450km version was still doing Mach 3-3.5. New P-15s ? Vizags ?
The clues are unclear. I recall reading an interview by Maksichev where he said there will be an additional gain of 50Km to the missile when it's upgraded to mach 4.5.
He pointed out the range increase of 50Km will come with a speed increase. But someone else had pointed out there will be a range increase due to a new fuel injector system.

We will come to hypersound via an increase in range. We have already confirmed 400 kilometres, in order to increase the range to 500, it is needed to increase the speed. Now the missile flies at speeds of 2.8 mach. We will achieve the speed of hypersound through modernization, it is more than 4.5 mach," Alexander Maksichev, the managing co-director of the BrahMos Aerospace company, told Sputnik in April this year.
The new variant of the radar-guided missile will carry the same amount of fuel as the earlier versions, but will be fitted with an enhanced computer-controlled injector system that will better regulate the flow of fuel into the engine’s combustor, thus greatly improving efficiency, the source added.
So there are two numbers thrown around. One is the upgrade from 400 to 450Km, which was tested in 2017, the other is to 500Km. There's nothing definite without them actually coming out and saying it, but the clues are there.
Right now it's unclear if the mach 4.5 version will be the upgrade to 450Km or the upgrade to 500Km. Or if both these missiles are actually the same. It's likely the 450Km version has had its speed increased to mach 3.5 along with a new fuel injector whereas the 500Km version will get its range boost with the speed upgrade to 500Km.
The Vizags, yes, are getting the a "new" version of the missile.
Laser DEWs are susceptible to damage from gun vibrations.
They will eventually take care of it, since it's expected that such weapons will be carried on SPADGMS, ICVs, tanks etc.
Kolkata class has adequate LR-AD missiles. They could use some point defence missiles though.
I find it weird that they haven't yet gone for it. Or they believe Barak is plenty on its own.
Couldn't you just have cannisters of different heights for AD missiles. They can have the same length & breadth. So the missiles can be quad packed but the cannister wont take up as much space.
Sure, you can have slightly different sizes, like on the Mk41 with the strike and tactical modules.
Even with 2 sizes, you don't really save space.
Otoh, Slyver takes it to a whole new level with 4 different sizes.
But with Slyver, you end up with the same weapon-specific spaces like we have on other ships. Except that there's some level of commonality in internal systems which makes it slightly easier to maintain it. However, in our case, we will end up with a massive size difference, like the one between Brahmos and Astra. The only answer is to go for larger ship designs.
What is the big hurdle with increasing beam length ?
It was a problem earlier, but it's nothing today. We just gotta design a new ship with a bigger beam instead of modernising the same design over and over again and call it A, B, C etc. Hence the need to do what the Chinese did with their Type 055 and go for a whole new family of ships.
The NGD/P-18 class is supposed to be 13000 tons in displacement as opposed to the P-15A/B which are ~7400-8200 tons. So we can assume everything about the NGD/P-18 to be much larger. The NGF will probably end up using the same hull as the NGD, so.....
Yeah, it's finally going to take us to global standards.
How a 13000 ton ship is called a destroyer & not a battlecruiser is beyond me.
Interesting story there.
Cruiser and battlecruiser were for specific ship classes in the post-Dreadnought era, long before guided missiles became the norm. These type of ships had battleship level firepower, but with significantly lesser armour. A battlecruiser was a downgraded battleship and a cruiser was simply a much smaller battleship. A destroyer was smaller than a cruiser and it's job was to protect the battleships and battlecruisers, while cruisers performed independent missions where a battleship wasn't necessary.
During the Cold War, the Americans had these ships called frigates, and the Soviets had these ships called cruisers. Both were the same and performed the same missions. But due to the difference in designations, there was a fictional "cruiser gap" created in the minds of politicians and bureaucrats since the American cruiser was different from the Soviet cruiser. In 1975, the USN reclassified all ships and Ticonderoga was supposed to be designated a GM destroyer with a DDG designation. But when it went in for approval, the Congress rejected it because there was already too many "destroyers". So the USN simply changed the designation to CG, as GM cruiser, instead for approval. But it performed the same role as a destroyer, ie protecting larger ships like carriers and LHDs.
So the term "cruiser" is simply a Cold War era relic used for political purposes by the USN.
The Soviets simply named their biggest destroyer "battlecruiser" and their smaller destroyer as "cruiser". This was also political, since the Soviets did not have an aircraft carrier similar in class to the Americans. So this was their attempt to stand out.
Both are slowly moving to more modern designations used by Europe, South Korea, Japan, India etc. Zumwalt class destroyer, Lider class destroyer etc, the USN adopting Europeans standards for frigates and so on. They did attempt more politics with the CG designation, but were later shot down since they wanted to modify the Zumwalt design and ask for more ships. They were told to use the AB class instead, so status quo for them.
The Americans and Russians have to change their designations, we are doing it right.
Seen it. Uses a similar stepped pedestal set up on the froe deck. Interestingly the larger missiles are below & the SAMs are on top of the pedestal.
The simple reason being the bigger missiles need to be kept away from the bridge because the separation is too small, considering the size of the ship. Plus the space below can be used.
We will continue relations with the Russian no doubt. But I think the scope of it will be limited going forward.
This is a separate topic in itself, but I don't think the Russians are in a very comfortable position with respect to China so they will want to keep engaging with us. Otoh, we want to reduce imports from all sources, not just Russia. But we are going to depend on fighter jet imports for a very long time and Russia is crucial if we are to maintain higher capabilities, or we will only get shafted by western countries by chasing behind the same technologies from them. After all, Russia is one of the main reasons why the Europeans are willing to share engine tech with us for AMCA. "Share tech or we go to Russia" is the best threat we've got. So there's at least a 10-year window for new deals with Russia, including Brahmos-2, before we become self-sufficient enough to reject imports from all sources.
