Brahmos Supersonic Cruise Missile : News, Updates and Discussions

cruise speed is usually little less, in the early days i read somewhere it was cruise at 2.5 mach .

Yeah I know.
General cruise speed is ~2.5 mach, with peak speeds of mach 2.8-3.2 during cruise phase.


Does the line suggests current latest varient having general cruise speed of mach 3+ then top will be mach ~3.5.
?

From what I know brahmos ng's top speed is supposed to be Mach 3.5 so general cruise speed should be mach ~3+.

peak speed means the final dash and hitting the target. usually speed is stable during cruise flight by flying at a specific height/altitude without engaging the extra thrust ie leveling out. Once the fv has to ascend or descend it needs to engage either aerodynamic control or extra thrust accordingly. But the actual cruise phase, the altitude remains the same.

You can then set up waypoints and in that mode it is like breaking a whole long range cruise flight into smaller ones to avoid detection and engaged by enemy AD. Usually these missiles have a live ad zone map, which is why TERCOM Radar altimeter etc aid in navigation after the data link update about live status of those enemy zones. Then the autopilot of the missile itself correct its course by virtue of data gathered via the tercom & radar alt height information etc and evade such zones. Missiles are way more smart these days.

About the higher speed, it is possible. One way of increasing range is of course increasing the speed but keeping up with the same fuel economy. Mission time is usually considered not exceeding certain threshold hence the propulsion module is proven for a specific long duration flight.

Blue camo.
🥴
Are they planning to hide it in ocean or something.

Suitable camo for coastal region are greenish, desert tan or mix of both depending on the local enviornment

Bro leave cammo does Phillipines have the isr and targeting capabilities to use Brahmos effectively. Hitting stationary islands is easy enough but thr main point is to hit ships and I'm not sure Phillipines has the capability to track ships at long ranges. Perhaps Amreeka will help them?

Shore defence batteries are mostly responsible for own EEZ protection? That is about 200 miles possibly, ie within the 290km export version cover zone. Most countries operate anti ship shore based battery that way.

So as per the report

The ramjet (which is directly shipped from NPOM Russia still) is modified to create the 800km range variant. This means DRDL work is either on the engine itself, or in the feed lines, fuel flow controller, ignition timing improvement, optimised combustion etc on such aspect so the performance can improve. Certainly we know as per BAPL planning and DRDL too both the range and speed of the missile are to be increased. For NG variant a new smaller ramjet with 3.5 Mach speed, Brahmos gets a 5 mach variant that is still a ramjet powered Brahmos. DRDL showed 800km LR version.

Then Rajat Pandits report goes on and claims the ER version 450km just needs software tweaks and it suddenly becomes LR 800km variant. Well then why the modification work took place? What sort of convoluted logic is this?

You read it wrong. He doesn't claim that software tweaks are needed to convert Bhramos' 450 to B800. But the software onboard warships will need tweakings ( integration) when B450 gets replaced with B800 on the ships.

So that LR version will likely have such bumped up speed, I expected same as NG version while the mach 5 version to be of limited ER version. But this makes sense, if the engagement bubble is extended to like 800km from the current ER 450km , speed being that high is one way to limit the total mission flight time (else Brahmos loses its uniqueness quick reaction) without compromising its lethal nature.

One of chief scientists from brahmos program in an podcast said that the actual range of brahmoser varient is 600km while 450km is officially quoted range.

Does that mach 4.5 top speed indicates terminal speed when its just about to hit its target or during midcourse.

Yeah due to liquid fuel use range will almost always be a bit more, better fuel efficiency depending on flight condition and mission demand. Same reason why the subsonic ones can fly for so long distance. Key part is still the long range navigation & guidance provided to it either from the start or later updated via datalink satcom whatever.

terminal speed is always variable depending on the endgame planned. The cruise speed is for midcourse most of the time, even that varies as per flight route. You can implement multiple zones with multiple varied speed flight to evade enemy AD zones or via pre program.

So can we expect cruise speed of mach 3.5-4? in various profiles in midcourse when top speed mentioned us mach~4.5(i'm assuming when it flies at high altitude of 10-15km), and terminal speed of also mach 3.5-4?
