Ah, the old “India can’t do Mach 10 because they didn’t publicly say so” argument always a crowd favorite in technically shallow takes by chinese & Pork-e.............Let’s start with some basic physics........ A maneuverable reentry vehicle like the BM-04 MaRV "can’t reach Mach 10" because “India hasn’t claimed it” or due to “shock resistance limitations” shows a fundamental misunderstanding on your part which is no surprise of both reentry vehicle thermodynamics and solid motor SRBM kinematics. A ballistic missile with a depressed trajectory and high burn-out velocity can easily deliver a MaRV into Mach 7–10 regimes during the reentry phase..... There’s ample precedent.......the Iskander-M, and even the older Pershing II demonstrated similar performance envelopes decades ago............ BM-04’s body proportions and nose shaping indicate a similar class....short-burn, high-thrust solid motor with a maneuverable post-boost vehicle.
As for “India can’t handle shock resistance”....... you mean the same India that’s fielded Agni-series RVs with blunt-body nose cones surviving reentry at Mach 12+, conducted multiple hypersonic wind tunnel tests, and flight-tested the HSTDV at Mach 6 with onboard thermal management and scramjet ignition? Right. I'm sure they just forgot how to apply those same TPS and high-enthalpy flow models to a smaller MaRV with a short terminal glide.
Now let’s talk about those fins. They’re not random sheet metal slapped on a cone ........ they’re aerodynamically contoured, canted control surfaces optimized for lift vectoring and cross-range maneuver in the terminal phase.......... This is a design logic shared with missiles, which use aerodynamic MaRVs to complicate fire control solutions and exploit the latency in interceptor guidance loops........Glide isn't a flaw it’s the feature........ The reduction in speed is a deliberate trade to gain maneuverability, reduce intercept predictability, and penetrate layered defense networks.........That’s how you defeat modern ABM systems including your mighty HQ-19

, not by flying in a straight line at Mach 17 and hoping for the best..............So no BM-04 isn’t “underwhelming” because it doesn’t claim eye-watering Mach numbers.......... It’s technically sound, tactically disruptive, and, most importantly, strategically survivable , regards.
Oh dear

....... you’ve bravely waded into hypersonic discourse armed with a Kármán line reference and a shaky grasp of reentry mechanics. Let’s tighten this up before you hurt yourself with another half-baked Mach-number take
First, your question..... “Can this Indian missile reach Mach 5?” is unintentionally hilarious

.......... A mid-range ballistic system like BM-04, likely lofted to altitudes well above 100 km with a burnout velocity exceeding 2.5–3 km/s, will naturally reenter the atmosphere at Mach 8–10+. That’s not a design miracle........ it’s called physics, and it’s been doing its job since the V-2......... You don’t need a scramjet or a press release to make a conical reentry vehicle go hypersonic. You just need altitude and gravity which, last time I checked, India still has.... Probably missing in in eternal kingdom


........Now, your claim about “rapid deceleration” after booster separation shows a tragic misunderstanding of what this system is trying to do.......Yes, it slows down but intentionally..........It’s called a controlled energy bleed to trade velocity for lift generation, maneuver envelope, and lateral displacement......... Those fixed fins on BM-04 aren’t aesthetic, they’re designed to increase L/D ratio during the terminal glide window, allowing it to veer off-course and screw with interceptors locked onto its pre-glide trajectory........This isn’t a bug......it’s the whole point.......You can’t “predict-kill” what doesn’t stay on a ballistic arc......Systems like HQ-19 rely on extrapolated kinematic tracking........Once you throw in non-linear gliding motion, those nice neat intercept boxes fall apart.......That’s why this missile doesn’t need to hold Mach 10 , it just needs to maneuver unpredictably at Mach 6–8, right when your radar thinks it’s coasting to impact & no, the absence of a press release claiming “Mach 12” doesn’t mean it can’t do it.......That’s not how physics or credible programs work.........So maybe instead of rewriting aerospace doctrine based on vibes and brochure envy..... try looking at the actual design logic.... this is a manoeuvring reentry vehicle for God sake.
Bottom line? The BM-04 doesn’t need to flex Mach 12 on a brochure or scream through the stratosphere to prove it’s hypersonic...... It just needs to hit Mach 8, pop out those fins, pull a few lateral Gs, and make your precious HQ-19 miss like it's swatting flies in the dark.
So before you try redefining hypersonics with your Sino & that pedo forum takes......maybe take a moment… light a candle… and say a small prayer for the interceptor because by the time it figures out where BM-04 actually is, it’s already too late
