It's not about apeing the West but applying logic to the situation, resources are finite, creating extra demand on those resoruces (manpower) only has a counter productive effect on the overall combat capabilities of the IA.

Becuase of mechinisaton and automation, a 30% cut in the manpower of the IA will EASILY result in a 400-500% increase in the overall firepower of the IA as a whole.


They have tweaked the design at the front^

Compare it to the DRDO test vehicle:

Good to see that they aren't standing still, refinements are coming non-stop.

It's a broad issue , where I mentioned about aping the west as one of the issues.

You are correct in your opinion , but as per my views I believe the problem lies elsewhere do you know anywhere near 50 % of army manpower is tied up in support role like logistics provisioning , mro, supply chain, base maintenance , clerical stuffs etc etc.

If I opt for large scale digitisation and out source non combat related management matters etc to certified and vetted service providers , I will be able to save money as well as reconfigure my personnel towards combat roles.

Let's see what future holds , I have no problem if you options or mine or anybody else's is implemented as long as it serves the interests of the country.

Ground clearance looks fine to me as the wheels are placed towards the front and rear of the vehicle with little overhang. Reminds me of the Jackel a bit:

What's most interesting about the LSVs that are coming out now is that they have flat cargo beds:

This is very JLTV-esque, will allow the markers to create an entire family of vehicles from the same platform.





Isn't that a BM-21 Grad launcher?

AL truck looks very similar to TATA defence trucks:

It maybe a grad carrier , because it is covered it gives the impression of something else.

Another poor example doesn't justify an anomaly

There seems to be two versions of AL's 4x4 LSVs.
One is very poor in the ground clearance (even when compared to the reference you posted - look at the below side view, instead of the bottom-up view). The Second one seems to have pretty good ground clearance (see the second pic below)

Yes, increasing the "tooth to tail" ratio needs to happen and Parrikar had implemented something along these lines to "cut the flab" but the reality is that the IA is still ADDING manpower to its ranks.

This is counter productive for the reasons I have stated, the IA's senior brass remains stuck in early 20th century thinking where it was all about boots and bayonets, this is seen in pretty much every decsion they make, the "batman" system just proves this to a absurd degree.

Yes, I think that was after they demonstraed the automatic ride height control, the vehicle can be lifted and lowered as the needs dictate.

Regarding un colors No idea , maybe

That could be the possibility,,,else that ground clearance would be totally unacceptable for an off-road vehicle!

Bhai, can you put these pics in defexpo thread. That should be useful to have them in one place for later reference.

DRDO hands over first indigenous heavy weight torpedo Varunastra to Indian Navy

CHENNAI: The Defence Research and Development Organisation (DRDO), the military research and development arm under the ministry of defence, on Wednesday handed over three critical indigenous technologies to the Indian Navy, including the first indigenously developed heavy weight torpedo Varunastra.

At the DefExpo 2018 being held near here, the DRDO also transferred 10 technologies developed by it to the industry for production for the Indian Armed Forces. They include grenades, missiles and sonars.

Defence minister Nirmala Sitharaman handed over three technologies for the Indian Navy to Chief of Naval Staff Sunil Lanba. It includes processor-based mines (PPBM), VLF modulator and heavy weight torpedo Varunastra.

A DRDO official said Varunastra is a ship-based ESM system developed for intercepting all modern radars. PBBM is deployable from ships and can deter movement of adversary.

Ten technologies, including Astra air-to-air missile system, which was tested in Su-30 Mk1 and is likely to be integrated into Tejas LCA and other platforms, were handed over to private and PSUs for manufacturing. The technology transfers also included anti-thermal/ anti laser grenade, CAIRGIS geographic information system, two sonars -- Humsa and Abhay -- and a sonar dome.

A stamp and a souvenir, which has details of all technologies developed by DRDO, were released to commemorate the 60th year of the Defence Research and Development Organisation.

The video says that there is adjustable suspension and ride height management systems.

Yes, even demonstrates it in the video.

=
-the fact that x % increase in VELOCITY OF TRAJECTORY will only increase horizontal velocity by only 85%of x%

@Kshithij

My bad. The increase in horizontal velocity for the highest range trajectory would actually be only 70% of the increase in trajectory velocity.

 

[Rahul Singh]

Bloody lowlife journalists. QRSAM has had a couple of failures (and a couple of successes) and they spin this as India’s ENTIRE missile development is hitting a rough patch?


We’ve had decades of these assholes talking Indian products down and even now they still are despite all the successes we have seen demonstrated

QRSAM system has VL Astra MK-1 coupled with X-band MMR and supported by an S-band BSR. For DRDO it is not even a challenge just an engineering issue.

Minor tweaks in airframe and software will solve every issue. Canister launch in VL and slant mode may require tweaking the software a bit and maybe some changes in the airframe to make it more aerodynamically stabile.

Where is Prahaar? Pralay should ideally have 500-600 km range in order to threaten tibet and chinese infrastructure near our borders and to replace Prithvi-1/2 & 3. Agni-1P on can take care of 1000 km targets and beyond.
If and when Prahaar comes it should be built up in numbers to rain down metal on anything within 200 km range.

Prahaar missile in independence day parade of 2013:

We have different missiles for different roles. Prahaar is a cheap but accurate missile, something like Pinaka but with heavier payload and better guidance. Pralay is a substitute for Prithvi for 400km range and to cover most of the targets in Pakistan and entire Bangladesh. Prithvi was liquid fuel and hence undesirable. Pralay is an appropriate substitute for it.

For 700km, we already have Agni-1. There is no need for any other missile. Agni-1 is a fully functioning solid fuel missile with modern guidance.

@Kshithij

My bad. The increase in horizontal velocity for the highest range trajectory would actually be only 70% of the increase in trajectory velocity.

I know that the maximum horizontal velocity increase is Cos(45) = 71%. And maximum vertical speed increase is also same as Sin(45)= Cos(45).

The maximum distance of projectile is (V^2)/g (V is total velocity, not horizontal)

So, if the velocity is increase is 15%, the distance should increase by 1.15x1.15 = 1.32 or 32%. If the increase in velocity is 20%, range must increase by 44%. If the increase in Velocity is 25%, range must increase by 56%. There is however, viscous drag because of which some amount of velocity will be reduced, thus reducing range. Also, some rounding off will be done to maitain a round figure. Even if the range was 430km, it would still be written as 400km.

The missile does not have stage separation and hence lot of energy is wasted in dragging the heavy motor and missile vehicle along. So, I get your point.

Finally, you are seeing some logic!!

The maximum distance of projectile is (V^2)/g (V is total velocity, not horizontal )

I don't want another debate on this but your formula is wrong! That formula works for a projectile launched WITHOUT thrust-in-flight (rocket powered)! So your 32% distance increase for a 15% velocity increase in incorrect! Further it doesn't take drag into consideration!
