Prithiv -II tested with modified ballistic trajectory

[Yogi]

The maneuvering comes at a cost of velocity, if you see, it took 8 minutes for a flight range of 260 km, which is quite longer time. So:

1. While it has better potential ABM evading capability and increased range, it is slower and the size of Prithvi missile also provides a bigger target (since there is no warhead separation). So e.g. Ghaznavi and Prithvi should not be compared in this case IMO.

2. No, Pakistani missiles have simple ballistic trajectories.

3. India won't gain any advantage, since Pakistan does not possesses any ABM shield.

4. Yes, it might be a technology demonstrator for Shaurya/K-15 missile. Lofted trajectories are possible only with fins, so Agni series cannot have it IMO.

5. No, Pakistan does not have any ABM. Prithvi-II is as deadly for Pakistan as it was before.

but Agni II has fins :

although i don't think it possess maneuvering capabilities.
however, whats the possibility of fins being added on Agni IV n V as both of them r still in development phase n DRDO has claimed earlier that they r trying to develop MRAV n MRIV tech for its missiles.

That's interesting! Requires very sophisticated computerized thrust vectoring technology! If they've achieved that, then .... Way to go!!

Not thrust vectoring, it's useless for a missile of the mass of Prithvi-II. It's the lift generated from the controlling surfaces.

These fins on Agni-II are an old design, for flight stability of ReV during course corrections. If you recall, Agni-II was introduced before Agni-I (which had no fins) , and all the later missiles in series had no fins. When the second stage separates from ReV, these fins stabilize the ReV and a gimbaled engine inside corrects the course which was disturbed by jittery rocket flight, and the whole package is jettisoned later.

All the newer missiles use thrusters for flight stability of ReV during the period in which the course is being corrected by the thrusters themselves.

None IMO. Agni IV and V won't have any fins, and neither would have MARV capabilities while re-entering (they could maneuver in space though). You see, while re-entering, the ReV should be very stable, and the most common method of stabilizing the ReV is to spin it with thrusters. It is impossible in my opinion to guide something which is traveling at hypersonic speeds and spinning all the way.

It's actually quite the opposite, for an inertial guidance missile warhead, spin stabilization is the optimum method of maintaining accuracy is the terminal phase.

Yes thats what I said. INS guided missile MUST correct the course before it sets the warhead into spin. Spinning makes sure that the warhead stays closest possible to the course which was correct by the ReV. But after the warhead starts spinning, you cannot change its trajectory (i.e. guide it).

Okay, then there was 'galti se mistake ho gaya' in understanding it.

+1 for Aseeb for all his posts.

Fully agreed.

Guy, can you answer my question?

Why the exhaust look different to me in color? May they be trying different different fuel for missile? I see same color exhaust in Russian and Chinese rockets.

No masla, happens all the time.

The orange-ish exhaust is that of the liquid fuel (Nitrogen tetroxide (N2O4) and UDMH), used in Prithvi and Chinese/Russian Rockets. The orange tint mostly comes from N2O4.

Thank you Aseeb but why it appears to a bit different from what I show in previous tests?

It just appears to you that way. The exhaust is dark orange in color originally, but the color changes later because of the rapid diffusion in air and mixture of dust being thrown off by exhaust.

Thank you dear.You seems to be a knowledgeable guy. My regards.
