Indian MBRLS Pinaka Thread

So which variant of pinaka did Armenia buy?? Hopefully it's guided one so we can get some self marketing otherwise they can't do much with CEP of unguided ones.

Does anyone know why the guided version has a reduced number of tubes per truck ?

Because its guided.

Due to increased physical dimension of guided rockets espically due to control surfaces.

Dimension of Guided Pinaka is 214 mm just like the unguided version. Only difference is in its length.

The width of the missile has missile has increased due to control surfaces.
Don't know for sure but I think guidance computer along with GPS/NavIC receiver also caused increase in width.

We have been theorizing based on display models of both .. In these the fins are identical .. @Okabe Rintarou gave the theory the fins could be foldable or be actuated but not both hence the larger space required..

@AnantS has already shared this pic. But let me share it again.

Here we could see that the nose cone vanes are actually based on an actuator base (section-III), which means they are folded inside the launch tube and only do gets deployed once launched just like the tail fins. So no point of enlarged dimension due to control surface.

Now look at these pics of Guided Pinaka launch.

These are screen grabs of the moment when the rocket just emerged from launch tube. Could you see any control surface on it?

The control surface however is quite visible in the last pics.

I highly doubt Pinaka was used in Kargil War...I am sure Grad was used..

Pinaka rocket launch: Pinaka: India's highly successful guided weapon system

Pinaka is an indigenous multi-barrel rocket launch (MBRL) system, which has been developed by the Defence Research and Development Organisation (DRDO) for the Indian Army. Its weapon system has a state-of-the-art guidance kit bolstered by an advanced navigation and control system. It is one of...

Source.. Cause the only source we got implies that the dimensions are the same.

Source.. Cause the only source we got implies that the dimensions are the same.

If dimension were same then we would have not changed the launching pod or reduced the number of barrels. We would have continued with the same proven launch mechanism.
With simple observation one can deduce that due to change in dimensions of individual rockets/missile we had to change the launching pod.

Where have you observed this ? I'm asking for source not conjecture.. We have done that enough already .

If the CEP is 60-80m even for guided Pinaka then I presume this is nowhere near high-precision HIMARS ? It is just some trajectory correction so that the rockets do not fall way off the target.

True. HIMARS have a accuracy of 1-2 m.

Looks like it achieved 8meters in this

~10m, but that is of no value if it cannot achieve that consistently. Circular error probability (CEP) determines the accuracy.

Here a picture of a guided pod, the tube is wider at the front to accomodate the guidance fins. IIRC this reason was given by some DRDO official itself and is not speculation.

How did you arrive at that value? TIA

Estimating from length of missile.
