Brahmos going mach 4.5 .is this true?

BrahMos Corporation to Test Upgraded Ramjet Engine for Mach 4.5 Speeds - Indian Defence Research Wing

SOURCE: RAUNAK KUNDE / NEWS BEAT / IDRW.ORG BrahMos Aerospace, the India-Russia joint venture behind the formidable BrahMos supersonic cruise missile, is set to push the boundaries of missile technology with a tweaked ramjet engine designed to propel the missile to speeds exceeding Mach 4.5...

Yeah, they have been developing a near hypersonic version of brahmos by modifying existing "ramjet" engine for few years now.

even to guide it to 300+ km with tejas or rafale you would need awacs in numbers, which is not the case with india
uttam mk1 caps at 230 km, awacs would be able to send it to 300+
only super sukhoi would be able to self guide it to the locked target at 300+ range

You are missing 1 scenario.

Cats warrior, big brother of cats, ghatak etc gets close ( about wvr distance) to target, mothership non stealth fighter at 100-150km behind the stealth loyalwingman carrying very long range air to air missile, using loyal wingman drones to guide the missile.

We can also change those drones to any other stealth platform with sufficient sensors.

sorry bhaiya i just said what that proff said

as for ground roles, ghatak is getting eots, so it would be perfect for ground attack, but it wouldnt suffice if we were to use brahmos or rudram 3, a larger ghatak ( double engine ) would be needed to deliver hypersonic or larger cruise missile platforms

as for a2a missile truck role, cats warrior with iwb long enough for astra mk3 would be perfect, we can keep them in the front to increase the range of astra and it can act as a decoy or sacrificial aircraft for amca and rafale if they are under nez of a missile

Hope army also asks for drdo to make something like BONUS and Smart 155mm ammo for anti armour ammo. That's the next evolution after DPICM for anti armour application.
Also, I don't think Ramjet powered arty shell is worth it given that explosive content would be very minimal. Only if this has sub-meter level accuracy and some kind of terminal seeker while also being very long range like 100+km, this shell would be worth it for only limited applications like targeting enemy vehicles, radars, AD stuff and long range fires platforms. Also, highly doubt Ramjet shell would be good for anti bunker role.
Anyway, packaging all this stuff inside a arty shell will be a colossal challenge in itself.

Also, any idea what happened to that TGM terminally guided munition requirement from army which was floated under make1 or 2. They asked industry to develop them while not roping in Drdo.
This is different from CCF requirement. I doubt anyone has even shown a model of TGM though for CCF, many exists.

The ramjet shell drdo is developing Is supposed to have ~80km max range and per unit cost once in full production should be under 30k dollars, according to what I read.

So IMHO, worth it for niche uses.
Specially In himalayas against china, where 155mm howitzers like atags will play a huge role.
And if that under $30k per shell cost is achieved than a pretty good low cost long range(~80km) howitzer capability to complement more expensive rocket artillary.





As for smaller warhead, we can still fit a warhead the size fitted in javelin anti tank missile( ~800mm rha penetration) in that ramjet shell if we assume it's size to be similar to normal artillary shell.


Though, western ramjet shells are reaching per unit prices that is more than their similar range guided rocket counterparts, in that case just using rocket artillary is better.


So if cost can be brought to 30k-50k per ramjet shell, IMO it becomes worth it in general.

Yes 30k usd is a steal if we can increase the range to 100-200km.As in foreign countries it's around 150-160k usd per she'll.

Another concept that I see potential of based on recent skirmish is of mobile independent SAM units of 80-100km range, something like QRSAM or Akash-NG (first mobile launcher) which can be dispersed close to the border 20-25 km depth (plain area) and fire at very short notice.

Emission wise they remain silent and are interlinked with ASP network and take target of opportunities. If they need to provide target updates until SAM goes pitbull, that would be less than 5 minute of vulnerability. Ideally, these SAMs should be able to receive target updates from other fire control radar further behind, then there is minimal vulnerability.

This will give less reaction time to PAF and push them further deep into their territory, it will threaten them from unexpected direction.

Also, could play a role in managing stealth threats if they come close or cross border. Let's say if VHF radar detects J35 then mobile SAM unit can emit it's fire control radar and being so close to it might actually be able to track it and fire SAM at it.

I thought that WAS the standard practice!!

I meant something like below, that has minimal footprint and doesn't need to be deployed all the time. It can be mobile along highways close to the border or be under shelter and when it has a target of opportunity it gets ready to fire within 1-2 minutes.

Basically QRSAM but longer range and something that is not deployed as battery but more independently across a wider front.

Or just get a bunch of flying-wing UCAVs hooked up with AI-enabled autonomous navigation and targeting systems, load them up with a bunch of runway-denial and anti-radar munitions, and send them the PAF's way. That should do the trick, no??

to join drdoo after btech or mtech you need to give gate and clear it and then written exam and interview right??? thats the procedure on internet

what if i want to join navy's warship design bureau??? no info available on yt or internet

That they will decide not you as per your skill level .First get a good gate score in mechanical engg then apply across dept like drdo,mdl etc

It Means we can shatter skardu air base completely at the cost of one bramshos missile (3 million = 100 shells)
