@Chinmoy bro any update on any kind of our uavs or ucavs or project cheetah?

The IAF is aware of the role of unmanned systems in future warfare and has initiated programmes to develop and integrate niche technologies related to unmanned systems. In addition to the development of HALE/MALE (high-altitude long endurance, medium-altitude long endurance), the IAF is also developing unmanned systems in collaboration with the private industry. These programmes include Manned Unmanned Teaming (MUM-T), Air Launched Flexible Asset-Swarm (ALFA-S) and Tactical Interdiction & Attack Air Vehicle (TIA-AV 50). The IAF has prepared a roadmap for induction of RPAs (remotely piloted aircraft) to meet both the short- and long-term operational requirements. The plan includes various types of systems ranging from small drones and counter drone systems to the MALE & HALE class of RPAs along with a weapon delivery capability.

Sir you are knowledge able, just tell me are they upgrading the gun and ammunition also ?

T-90 is a license production. You can indigenize the components, but not the design. Any design change you want to do would have t be certified by OEM. So 125 gun would be there.

 

[Chinmoy]

Are they upgrading protection I mean new era or aps

APS for T-90 MS has been presented before DAC. But for that too, you have to approach OEM for certification. Can't say about the older 'S', but for 'MS' it has been proposed.

Wishing my fellow posters Happy Makar Sankranti .

Here's an awesome poster from DRDL. Do feast your eyes and relish every bit of it.

Pay close attention to SLRCM and HSTDV.

Supersonic Long range cruise missile is an enlarged upscaled , modified STAR missile mated to a solid booster. It's liquid fuelled ramjet missile ensures it has a greater than Mach 2.0 speed throughout the flight trajectory making it much complicated for the defender to detect and intercept this missile.

And then there's HSTDV. Gives Zircon vibes which itself looks similar to X-51A Waverider. Our hypersonic cruise missile Project , Vishnu is further along the R&D path than most people realise.

We have truly become Atmanirbhar.

Is it possible that Astra Ramjet (SFDR) is mislabelled as SLRCM?

 

[karn]

not even one company exists in the country that produces these?

I remember in one of the media "forums" Gadkari was requested by an audience member to look into manufacturing of magnets for use in motors. Gadkari hand waved it way like "if there is demand industry will cater to it" ... So it looks like magnets are not in the radar of the govt the way hydrogen and electronics assembly are.

When they will lose or again barely win after many unnecessary sacrifices,
In my opinion .
Then new plans will be drawn for next 40 years .

I bet that even in this decade we may not see ficv start inducting or may be the usual emergency imports bogaloo. I have no doubt that half prototypes shown on Defexpo are good but just check the last two RFI for ficv and you see completely different specs so if you don't fix how do you come to a conclusive ficv.

Similiarly, now that Abrams x, embt have come with crews in turret, IA might be not sure itself if it wants a remote turret or not.

I hope they just fix the requirement without changing them too much. Considering that might not happen, atleast add a Desi berezhok combat module to our BMPs + situational awareness system+ aps.

Thats the STAR supersonic target never heard about the SLRCM term before perhaps its a new term but do note that the names were a written by a guy in twitter and are not official in that pic

APS part wont happen, and TBH shouldnt happen. APS is going to seriously injure troops standing around it, and while you can get troops to shoo away from tanks, you cant do the same if they are riding in the same vehicle.

 

[shuvo@y2k10]

There was also a Army proposal to industry to improve the penetration capability of T-90 APFSDS to 700-800 mm, for which the vendor was allowed to modify the turret.

I wonder any private player has shown interest in such projects.

New Indian made composite armour makes M-17s lighter

India’s Mi-17s gets indigenous armour to stave off fire from small arms, snipers

Unlike the steel-made Russian armour, the ones being manufactured indigenously are made of composite that reduces its weight by 40 per cent.

By looking at pics one cannot determine the aero/hydro dynamic characteristics/performance

IMO there are not for steering underwater, K4 travels inside a bubble created by the pseudo 1st stage (nose cap) which starts firing once it exists the submarine silo, it barely travels <100m underwater ( will not give the exact depth)

Those fins are required for aero dynamic control during the low dynamic pressure zone experienced post exit from water till the time the pseudo 1st stage burns out at a predetermined altitude

After that the base shroud at the bottom of 1st stage with the control surfaces are discarded , which than allows the actual 1st stage to fire and then the FNC (flex nozzle control ) of now burning 1st stage starts exerting thrust control

Whoa! When you say a bubble created by the 1st stage, do you mean something like super cavitation?

 

[porky_kicker]

Whoa! When you say a bubble created by the 1st stage, do you mean something like super cavitation?

It's the psuedo 1st first stage which is on the top of of the missile which fires during ejection from silo of submarine creating a gas bubble around the missile (to what extend only designers will know) which helps to reduce the hydrodynamic resistance while travelling underwater

Primary purpose of the pseudo 1st stage to propel missile underwater, water to air transition, gain sufficient altitude for the actual 1st stage ( on the bottom ) to fire

IMO working principle is more or less same as supercavitation but not dedicated application of same ie like in Shkval torpedo whose entire design is built around to leverage supercavitation to the maximum extent possible . This is my personal opinion for what's it's worth.

Aps enhances the survivability a lot against atgms and rockets, which seems to be one of the large inflictor on armour nowadays.
I would rather prefer my if be saved and on danger to infantry, new tactics can be made.
I believe other countries which have adopted aps on ifvs have done the same.

No, you don't need the certification from OEM for change of design as long as you:
1. import the quantities of components listed in the contract;
2. take the responsibility of those products with your own design change.

Looks like even TATA 4x4 LPTA 715s have been exported to Morocco.

I wonder what do Moroccan jingos have to say about it? What's the feedback?

I am talking about general, not cheating and thieving procedure here.

no. We have experienced decades back when DRDO churned out Tank Ex from T-72. Turret of Arjun, rest all all bits of 72. Russia balked and stalleback Td. They saw threat to t-90 orders. Given Russia is under sanctions and no new defense deals shall be signed perhaps russia might be amiable to licensing deal where it allows modification for small fee (and of course - owning IPR rights - as in most such contracts, any design modification done by end user - can be freely adopted by OEM if it desires.)

I have only seen one example of IFV with APS actually being used, that is Hungary - And they are not exactly role models. Even Israel, who pioneered APS tech, chose not to put them on most of its IFVs. (though even if they do do it in the future, it would still not apply to our situation since their IFV is more armoured than their MBT). Rest all have trials and stuff, dont see large scale adoptions.

The entire point of IFVs is to operate in close proximity to troops - If you separate the two, IFV is just reduced to a shitty tank with seating capacity :/

Primary offensive and defensive power of IFV is the troops it carries, not the armour or munitions. It is not the spear, the troops are the spear. IFVs are supposed to provide covering fire while the troops seize the objective.

Another thing to keep in mind - IFVs , and armour in general, is not meant to be invulnerable - All these systems (APS, heavy armour, ERA, sensor data) are just meant to increase survivability. In the end, these can all be defeated, and ever since armour came on to the battlefeild back in WW1, there were cheap counters to it.

Sums it up pretty nicely:-

"Ask not what you can do to the tank - Ask what the tank can do to you"

Same goes for IFVs.
