Would it be possible to have MOLLE like straps across the BPJ so that troops could adjust the pouch positions and other gear according to their needs. Or modularity isn't given much after thought

 

[Kshithij]

You are conceptualizing the whole thing in a wrong perspective.

Whenever you release a body from a moving platform to fall free, it would have its own relative velocity. Now velocity being a vector quantity does have associated numbers like speed, direction, magnitude. At any given moment of time these numbers could be calculated or could be pre-programmed.

In case of recent Brahmos firing, you might have noticed how the missile has undergone a free fall before firing its engine. So its relative velocity at the time of fall is equal to what it was during release and its direction too was what the fighter was flying to before release. Now the firing took place because of INS, not because it has been triggered off remotely. In same manner, INS does works in a BM too. The only difference is in firing mechanism. For a ALBM, it would be pre-programmed for it. It would know at what altitude it would have to go off.

Moreover a Bomber or cargo plane would not roam off aimlessly before releasing its payload. It would have its precise location and altitude known to it. Same would go to the missile before release. So you see, there is basically no problem in releasing a BM from plane. Moreover in the video I shared, it had been shown how it fires up. Only problem is to stabilize its fall which is also shown to be taken care of.

Please don't meddle with the definition of ballistic missile. We can launch missiles from a plane, but ballistic missiles are those that go in a parabolic path. If you want the missile to reach long distances, then you have to send the missile over the stratosphere where the air resistance is minimal. The peak height is in 100+km with Agni missile having over 600km peak height. This height is needed as the missile has to travel long distance without losing energy.

You are speaking of dropping a missile and making it fire? Then it will be a missile (missile is a precision guided rocket). If you want a ballistic missile, it has to travel high and far in a parabolic path with minimal guidance.

Ballistic missiles are simple missiles that simply fly up and then down with minimal course correction. All missiles with initial stage rocket which burns out quickly and then the missile simply moves with the initial energy is not a ballistic missile.

Would it be possible to have MOLLE like straps across the BPJ so that troops could adjust the pouch positions and other gear according to their needs. Or modularity isn't given much after thought

The BPJ appears to have fixed pockets stitched together. There appears to be little room for modularity.

If I am right, Indian BPJ is quite large and covers a large part of the body unlike USA's BPJ. This increases the weight. If modularity is added, the weight may further shoot up.

Here is a video of the MOLLE BPJ:

Snag Hits Quick Reaction Missile Test Again: Another Setback For Indian Missile Program
Wednesday, April 11, 2018 by Indiandefense News

QRSAM tested at Balasore rolled uncontrollably, fell into the Bay of Bengal Monday. This is at least the second failure for the missile in four tests
by Manu Pubby
New Delhi: India’s missile development programme is going through a rough patch, with another snag hitting the home-made quick reaction surface-to-air missile (QRSAM) during tests at the Balasore range in Odisha Monday.
The QRSAM system, being developed as an add-on to the Akash air defence missiles that are already in service with the Army and Air Force, has now undergone four tests, of which at least two have been unsuccessful.
Sources said during the latest test, the missile took off from its launcher successfully, but rolled uncontrollably during flight before ditching into the Bay of Bengal. The missile is being developed by DRDO’s Hyderabad missile complex, and top officials were present at the test site during the trial.
It is learnt that the DRDO leadership team on missile systems is studying the failure and is trying to find the root cause of the problem. Previous trials of the missile were conducted in June, July and December last year.
As reported by ThePrint, during the 22 December test, the missile hit turbulence within 1.5 seconds of taking off, as an actuator did not respond to a software command. The QRSAM is supposed to take down fast moving incoming air targets like missiles and fighter jets at extremely short notice.
India has been planning to showcase the Akash as a Made in India missile that is available for exports. In fact, the missile is being showcased at the Defence Expo near Chennai this week to possible customers who will be visiting the show. In addition, the Indo-Russian Brahmos missile is also being displayed at the India pavilion during the event, as an export option to friendly foreign nations.
The QRSAM is a recent DRDO project that was undertaken to meet demands of both the Air Force and the Army. The services had requested for imports to meet urgent requirements for air defence missiles, which were turned down after DRDO assured that it could develop the system indigenously.

For a weapon system which is under testing a failure is not a big issue.

What surely is very big are missiles already in service failing like this.

Is it just me or does others notice too that the pouches on this BPJ might be a tad narrow for the 7.62x51 magazines (that Army will be moving towards very shortly) - especially when magazines are placed in adjacent pouches???

PS: It is not BJP but BPJ.

Coming back to point, if the magazine is curved, it may be small but not otherwise. Also, there are pouches and pockets everywhere, including one in the groin protection pad, side and in the chest. There is plenty of space.

I am however not sure why there are many different sized pouches.

 

[Suryavanshi]

10 kg BPJ + 2 kg helmet + 3.5 kg rifle + 5 kg other stuff

Isn't it a little too much.

I corrected the typo before you replied (as is obvious from the 'original message excerpt' in your own reply)
Also, PS means 'Post Script', that's placed BELOW the main message - not above!

The 7.62x51mm rounds are about 1.26cms longer - the magazine will have slightly thicker casing too. Which means that placing two 7.62x51 magazines adjacent to each other would take about a FULL INCH more than when placing two of 7.62x39 or 5.56x45 magazines next to each other!

The probability of a soldier wearing a groin pad during combat is almost ZERO (they may wear it rarely in storming inside a building during counter-terrorism ops). And even if they wear a groin pad - NO BODY WILL SLING AMMO INSIDE IT!!

Different pouch sizes are to carry different things - grenades, radios etc.

It is next to improbable for a soldier to use both 5.56 NATO and 7.62NATO guns simultaenously. A soldier will use either of the two. So, let us only consider two 7.62NATO magazine pouches. In this case, I find the second (from left while lookig at picture) pouch to be too small in height to contain the magazine at all. I don't see a problem in the first pouch.

Again, the pouches are expandable and when two pouches carry magazines, one will expand to left, other to right to balance it. But, i this case, I find only one pouch worthy of carrying 7.62NATO rounds

10 kg BPJ + 2 kg helmet + 3.5 kg rifle + 5 kg other stuff

Isn't it a little too much.

Helemt weighs 1kg and gives only protection from 9mm rounds and shrapnels. The BPJ itself is lightweight -3kg but the plates can weigh more. But overall, it is not going to be 10kg. I remember going to school as a kid with a bag weighing 7-8kg and a lunch bag weighing 1-2kg.

Where did I suggest that a soldier will carry rounds of different calibers? Do you even know to read English?
I've seen a bunch of your posts - I think I told you about a week ago itself that your posts are the most brain dead posts! You understand very little of the topic but will continue to post rubbish all the time!

'expanding' into what? into outer space? In full combat mode all pouches will have something or the other. So to allow for the 'expansion' the soldier has to forgo stuff like grenades/radios?

BTW...any questions in this post is purely rhetorical. Please don't answer with anymore of brain dead logic. Thanks for your consideration.

I have seen your posts too. You think you are too detailed and ending up speaking shit. In this case I thought you were a moron trying to say that one pouch will have 2 7.62 magazine while another will have two 5.56 magazine. So, I just clarified for you thinking that you need some hand holding to do.

You regularly speak like a retard. What do you think the pouch is made of? Steel? If it is made of cloth, it can expand. To make you moronic brain understand here I am giving a picture:

In the first picture, which is of the biggest pouch, there is clearly room on the left (wrt picture frame) to expand. In the second picture, I find the pouch to be too small to be able to carry any 7.62NATO magazine at all. An in case it does have enough size to fit 7.62NATO magazine in, it will slightly nudge the smaller pouch on the right (wrt picture frame).

Unless you are a fools who has never had to tightly adjust bags, you will know how cloth bags work. There is no need to have exact dimensions. If the pouch is close enough in size, it will fit. 1cm difference will mean nothing. If you don't have basic common sense to know these things, you first need to learn more. Stop talking shit and go out of your basement

pralay missile only 350km ?

View attachment 24240

Isn't it strange that the decrease in payload by 50% from 1000kg to 500kg will increase the range only by 50km from 350km to 400km? Is this a maneuvering missile with unpredictable flight path?

Yes it's kind of intriguing
I am at loss to explain the low range increase at half the warhead weight.

You might be correct with your reasoning

You're an unashamed moron! I just explained to you that I had clearly mentioned TWO 7.62 MAGAZINES ADJACENT TO EACH OTHER or TWO 5.56 MAGAZINES ADJACENT TO EACH OTHER! But you still go on rant like an f'ing moron. Dwell in your own $hit!

I find the pouch to be too small to be able to carry any 7.62NATO magazine

Hmmm. That's what I've been saying all along. But your f'ing moronic brain didn't seem to understand. Not sure what exactly you're arguing about then!

You regularly speak like a retard. What do you think the pouch is made of? Steel? If it is made of cloth, it can expand. To make you moronic brain understand here I am giving a picture:

Hey a$$hole! cloth pushes itself out, but the extra size will also push out the contents in the adjacent pouch!!

. 1cm difference will mean nothing.

It's 1 Inch not 1cm. You maybe measuring yourself in cms and feeling good about yourself, but know that you're not potent!!!

 

[Enquirer]

Yes it's kind of intriguing
I am at loss to explain the low range increase at half the warhead weight.

You might be correct with your reasoning

Payload maybe reduced by 50% but the total weight might be reduced by only around 10%-15% depending on the total weight of the missile (assuming it to be around 4-5 tonnes)!

 

[Kshithij]

Payload maybe reduced by 50% but the total weight might be reduced by only around 10%-15% depending on the total weight of the missile (assuming it to be around 4-5 tonnes)!

Total weight of missile is given as 5ton clearly. You were shouting at me for not being able to read and you are doing this?

Next, the payload is not a burnable part of the missile. The burnable part of missile (propellant) imparts a certain momentum which is constant irrespective of warhead. So, the velocity of the warhead should increase with mass decrease/ By conservation of momentum, the velocity must be doubled for mass being halved.

Even if we take the viscosity to increase with velocity and thereby dampening the increase in speed, the range should still be higher than just 15% increase

 

[Kalki_2018]

So how long is Pralay? If it is meant to be a low threshold non nuclear missile (why else 1 tonne payload) then it makes sense to have it as compact as possible.
