The issue is not that Light armoured tank is not necessary but why import are better than BMP-2/Abhay? The import which is a possibility is Russian Sprut, which (can float in water) so its armour density would be near BMP-2 (which can also float). For wheeled tanks, why DRDO Armoured vehicles cannot be used to mount light guns & missiles. Also if this requirement existed then it did not come into being on one nice day, why could the Army not commission DRDO or Pvt sector to build prototypes??


The issue to me is what is the final aim of light tanks.

I dont care who produces it so long as we need it!

The need is what I am searching!

RayC Sir – “A light tank can maneuver in the hills better than an MBT.” This is something I disagree with.

Maneuverability is a function of power-to-weight ratio and drivetrain design and NOT weight.

Engines (diesel in tanks or gas turbines in helicopters) operate less efficiently in hot and high conditions.

So if a MBT with 780 hp engine has sub par performance at high altitudes, it is assumed that a light tank with 780 hp engine will perform better because of better power to weight ratio.

Reducing weight is one way of upping this ratio – that will reduce protection. The most logical option is increasing the horsepower.

An alternate to the above logic is upgrading a few MBT’s with engines having a higher rating. Keep the bulk of your MBT’s for plains use and upgrade few ones for High Altitude use. This is cheaper than buying a new genre of light tanks.

Use an MTU883 series engine in Arjun instead of present MTU838. Both have similar dimensions. http://www.mtu-online.com/mtu/products/ ... -vehicles/

Use 6TD 1200hp engine instead of the 780 hp engine in T-72. It’s designed around the T Series.

The Al-Khalid & Chinese tanks use a 1200 hp engine exactly for this reason. Better power to weight ratio keeping hot and high operations in mind.

No, they use it because its supplied by Ukraine, who helped in the design process and had the engine in production. 6TD is designed for T-64/80 and would need some work before it can be adapted to T-72/90.

The manufacturer says otherwise http://www.morozov.com.ua/eng/body/t72m1.php

But why did the chinese and pakistanis insist on development of 6TD-2 developing 1,200 hp when 6TD-1 developing 1,000 hp was readily available?

Anyways its off topic, point made here is the need for a compatible higher horsepower engine, irrespective of source.

Ok... the idea of fixing a new engine to existing chassis of MBT's is nice but will the road and the ground underneath be able to take the load??? Probably that's the reason they are going for light tank... to ensure that the weight of the vehicle doesn't cause sever damage to the roads and the ground beneath it... Just my humble opinion..

Tsarkarji, I think the question is not about laying better road... its about the ability of the soil to to hold the load placed on it... and afaik the himalayan soil cannot take that heavy load on a constant basis...

There is also a question of practicality of approach 1 vs 2.

1. Do we lay 10000 KM of roads all over Arunachal because we need T 72s to move and then be "tank ready"
Or
2. Do we just get lighter tanks and in addition keep laying roads as fast as possible? T 72s can keep coming in later with better engines gradually as roads improve.

Which is more practical and do able as well as within time lines?

There is also a question of gun elevation flexibility in mountains too. Right?

“Himalayan soil cannot take that heavy load on a constant basis” –http://en.wikipedia.org/wiki/Karakoram_Highway

Tanks have ground pressure lower than cars. Ground Pressure was the reason why the caterpillar track was invented in the first place http://en.wikipedia.org/wiki/Continuous_track

Areas where armour can be effectively deployed is mapped beforehand. Road network is required only up to staging areas. Thereafter field engineers assist movement of tanks. Planning includes surveying and choosing areas where to employ tanks. Use attack helicopters for direct fire where tank deployment isn’t feasible.

For elevation and crest clearance, you need SPA like Bhim, not tanks like Arjun.

There is also a question of total weight right, for many small bridges etc on the way, ground pressure is not the important value. Total load is.

So for many road areas, pressure it may take, but total weight can cause parts of road to sink.

Road network is required only up to staging areas.


But even then I see the logic of having light tanks to go where full tanks cant. There will always be such roads.

And then there is concept of lighter baggage train too right (as in smaller logistical foot print per tank)

So what stops us from building stronger bridges? Point is our poor infrastructure enabled light tanks will not hold back their better infrastructure enabled heavy tanks.

Lighter baggage train - true, the light tank may consume a few liters diesel less. But will it survive infantry TOW rounds or kinetic penetrators?

I remember all these arguments made by Prem Shankar Jha in Outlook magazine against Su-30 saying its too heavy, we dont have suitable airfields, large logistic footprint, etc. Today the IAF is on a major drive to improve airfields.

And thats the crux of the problem



For a low to medium tech product like this - its a joke that one needs to get it from abroad.

We cannot fight for long stretches with any leavel of independence relying on imported weapons.

The import shopping list is becoming longer with no thought to developing it locally and long term plans to build up competence

The soil and the geology of the location...

The fact that the IA has deployed heavier MBT in locations that can support it is proof that even they would want the heavier MBT in those places... So when they are asking for light tanks i am guessing they have checked that whether MBT's can be deployed or not and found that its not feasible and hence have asked for the light tanks..

A DRDO centre in Pune that is proud of its varied accomplishments is the Armament Research and Development Establishment (ARDE). Its most visible success stories are INSAS (Indian Small Arms System) rifles, Pinaka, the deadly multi-barrel rocket launcher (MBRL), and warheads for missiles and torpedoes, but it also has road maps for futuristic products such as guided rockets and precision-guided munition.

Anil M. Datar, Director (ARDE), said: “The ARDE has successfully completed the Pinaka project. It is in production now. The Army has ordered Pinaka systems worth Rs.1,300 crore for two regiments. Each regiment will have 18 launchers and associated vehicles. Pinaka is a major achievement of ours.”
Pinaka

A Pinaka MBRL, that is, a single launcher built on a Tatra truck, has two pods of six rockets each. Six launchers constitute a battery. The Army generally deploys a battery that has a total of 72 rockets. All the 72 rockets can be fired in 44 seconds, taking out an area of 1 sq km. Each launcher can fire in a different direction too. The system has the flexibility to fire all the rockets in one go or only a few.

“This is possible because we have provided a computer for fire control,” said Datar. There is a command post linking together all the six launchers in a battery. Each launcher has an individual computer, which enables it to function autonomously in case it gets separated from the other five vehicles in a war.

K.J. Daniel, Project Director, Pinaka, calls it “a system” and explains how massive each system is. A Pinaka battery has six launchers, six loader vehicles, six replenishment vehicles, two vehicles for ferrying the command post and a vehicle for carrying the meteorological radar, which will provide data on winds. “Today, we have orders for two regiments. In the future, we will have orders for 12 regiments,” said Daniel.
INSAS rifle

BY SPECIAL ARRANGEMENT

Daksh, the robot developed by R&DE(E) for handling improvised explosive devices.

Developing the INSAS rifle with 5.56-mm calibre was another big achievement for the ARDE. It went into production in 1993. And about 1 million INSAS rifles have been inducted into the Army so far. In fact, INSAS is a family of arms and ammunition, comprising a rifle and a light machine gun. The firing capabilities of the weapons are enhanced by daylight telescope and night vision. With the Army keen on having more effective ammunition for a short range of 200 metres, the ARDE busied itself with designing such ammunition. The first phase of trials is complete and the second phase will begin in October.

The ARDE will soon build Pinaka rockets with a longer range of 60 km compared with the present 40 km and make them smarter too. These rockets will have a combination of inertial guidance systems and global positioning systems. Datar described such guided rockets as “something between ordinary rockets and missiles”. Missiles are expensive because they have precise guidance systems. “In the next five years, we will have guided rockets. This is a cheaper way to meet the challenge of getting at high-value targets with high accuracy. In the future, we may go for rocket systems with a 120-km range,” Datar said.

The ARDE, which produced the gun barrel for India’s main battle tank Arjun, is now coming up with a special type of ammunition called Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS) with a calibre of 120 mm. The FSAPDS will also be developed for T-72 and T-90 tanks, which have guns of different calibres. The FSAPDS has already been developed for the infantry combat vehicle (ICV), which needed ammunition with a 40-mm calibre. The ARDE is now on the job of developing it with 30-mm calibre for the futuristic ICV.

The canopy severance system (CSS) for fighter aircraft in trouble is a different kettle of fish. When there is an emergency on board a jet fighter, the pilot has to eject through the canopy overhead without getting hurt. This requires breaking the canopy to make a path for the pilot. This is called CSS and the clean-cut is achieved by power cartridges that function with precise timings and pressure. Since the IAF has aircraft acquired from Russia, France and the United Kingdom, the ARDE developed indigenous power cartridges for them so that the IAF will not be dependent on these aircraft manufacturers for cartridges. The ARDE has developed 62 types of power cartridges, matching the performance of the original cartridges. “This is a service that the IAF acknowledges,” said ARDE officials.
Warheads & anti-tank ammunition

BY SPECIAL ARRANGEMENT

Anil M.Datar, Director, ARDE.

Developing warheads for missiles and torpedoes is an area of core competence of the centre. All missiles – Agni, Prithvi, Trishul, Akash and Nag – developed by the DRDO have warheads made by the ARDE. It is working on futuristic warheads, such as aimable warheads or those with fragment generators. It recently developed a 450-kg high-speed, low-drag bomb, which was a complete indigenisation of the Russian variety and with added lethality.

The ARDE personnel are happy that the Army has placed orders for an innovative anti-tank ammunition developed by them. It gets initiated only when a battle tank passes over it, and not a truck or a car. Its sense of discrimination is based on seismic and magnetic sensors. Datar explained: “We have collected signatures of different kinds of vehicles, what kind of vibrations they create when they move. The data is fed into the munition’s system. When a tank is moving, it will provide a signature. The processor tries to match it with the stored signatures. If it matches, it gives a signal and the munition explodes.”

An important area where the ARDE will focus on is precision-guided munition. It will develop guided artillery shells or gun-fired ammunition. The first of such precision-guided munition will be cannon-launched.

Sure lets build stronger bridges too. Meanwhile lets get the light tanks too.

Knowing India I think realistically the chances of getting light tanks is higher and the troops will have something.

Waiting for infrastructure development to be done before we do the right thing is waiting for Godot (that's my understanding of India)

The Chinese have no problem in having MBTs on the Tibetan Plateau since they have no hills to climb.

IMO, the same can be asked of MBTs versus modern infantry anti-tank weapons. In a hilly terrain, the weak armor sides, such at the top, of the tanks are exposed.

True, light tanks would have a hard time in Tibetan Plateau. But could it be that IA plans to use light tanks only defensively in our mountains. And any offensive role would be limited to aksai chin region? Is that feasible or would it be too much wasting of money for mainly defensive posturing and limit offense?

My guess is that the light tanks would never reach them... they'll be used only on defensive lines... not in the offensives... And with anti tank missiles they could probably take out the chinese MBT's even before they get into their gun range, in the plains... JMHO..

As I see it, if our MBTs cannot reach the Tibetan Plateau, then the Chinese MBTs likewise cannot come down to the Plains of Assam.

In Ladakh, MBTs can operate with recce.

Would mounting of super heavy guided mortars and deployment of armed air&ground drones justify using light tanks?

Perhaps only an engineering marvel which makes defending armor against any kind of projectile cheap & effective ('using a bullet to shoot a bullet'), would make such deployment feasible.

Realistically speaking, light tank seems to be similar to IA's defensive turretless tank concept.

thanks rupak ! where did you get this ?

incidentally
Q22. Is the light tank capable of:-
(a) Engaging MBTs at ranges exceeding the MBTs direct firing capabilities
with an ATGM in all weather and light conditions?


is specifically the point I was talking about earlier in the page about ATGMs being able to break the weapon symmetry wrt tanks.

what happened to the proposal to upg the BMP2 fleet with a thermal sight and better ATGM. I recall poster boards on it from Defexpo brspies.

btw TOI reports that IA and Khanarmy will soon start a joint exercise in Jhansi involving mech units. the khan is flying in 17 Stryker vehicles for this and will live fire Javelin missiles too.

so we know where the wheeled component is heading

US Dept of Defense - Strykers to Deploy to India for Exercise

The Army plans to deploy 17 of its Stryker combat vehicles this month to India for the first exercise of its kind in the country.

This is also the largest deployment of the Strykers outside of those sent to Iraq and Afghanistan, Army officials said.

“It’s one of the most important training exercises that we’ve done with the Indian military to date,” Army Lt. Gen. Benjamin R. Mixon said today at a news conference here. Mixon commands all Army forces in the U.S. Pacific Command area.

About 200 troops from the 2nd Squadron, 14th Cavalry Regiment, based out of Hawaii, will train alongside the Indian army in combat maneuvers using the Strykers, Mixon said. An Indian army unit of about the same size will join the Stryker crews in Babina, about 275 miles southeast of New Delhi, for the two-week exercise starting Oct. 12. The two armies will share tactics for using the Strykers in combat, as well as its integrated computer network system, Mixon said.

The exercise will end with a live-fire demonstration of the Stryker.

“We’re very excited about it,” the general said. “We think it’s going to be a good experience for our soldiers, as well as a very important part of our relationship with India.”

This exercise, more than two years in the planning, comes as the Defense Department continues to reach out to India to increase its military collaboration. Pacific Command’s top officer, Navy Adm. Timothy J. Keating, last month traveled to India and said officials there have committed to increasing their military relationship with the United States. Mixon said this exercise will help to build on that relationship and open doors for expanding such training there.

“We view it as a broad effort in our engagement strategy with the Indians that we want to continue to expand. It provides a … method to get at more engagements,” he said.

Mixon said the Indian army is anxious to train with the Strykers. Most military exercises in the country, he explained, have been limited to scenario-driven, commander-level exercises in which few troops are involved. Some of them included unit or troop exchanges between militaries. When U.S. forces join with other militaries in the region, the scenario typically includes both tactical and humanitarian training. This exercise is unique in that it strictly focuses on combat training and does not include a humanitarian piece.

“It’s the full gamut,” Mixon said. “It’s on the high end of fighting.”

The two armies also will share training on how to fight improvised explosive devices. More than half of the U.S. soldiers involved are fresh from a deployment in Iraq, where they dealt regularly with the homemade bomb attacks.

The unit is part of the 25th Infantry Division’s 2nd Stryker Brigade Combat Team, and is slated to return to Iraq within months after this training mission.

In the Pacific region, the U.S. Army also trains with the militaries from Thailand, Indonesia and Japan. The region’s largest combined exercise, called Cobra Gold, includes militaries from Thailand, Singapore, Indonesia, Japan and observers from 20 other countries. The next exercise in that series is slated for February.

“We’ve got a very active engagement strategy with all of the militaries throughout the Pacific region,” Mixon said. “It’s a very important part of what we do.”

well atleast there wont be kickback delays in US deals and the eqpt is good.

http://timesofindia.indiatimes.com/indi ... 099717.cms

India and US are now all set to launch their largest-ever ground combat exercise,
which incidentally is codenamed ‘Yudh Abhyas’ (preparation for war). But it’s really not conventional war that will be the focus of the 15-day wargames, which kicks off at Babina, near Jhansi, from October 12.

‘‘The focus of Yudh Abhyas is on mechanised infantry operations for counter-insurgency/counter-terrorism in semi-urban terrain. The aim is to further enhance interoperability already built through a series of exercises with US,’’ said a senior Indian officer.

Commander of the army forces under the US Pacific Command, Lt-Gen Benjamin Mixon, in turn, said, ‘‘It will be one of the most important training exercises that we’ve done with the Indian military to date...It’s on the high-end of fighting...We’re very excited.’’

The US, anxious to grab a major chunk of the lucrative Indian arms market, will undertake ‘live-fire ops’ of its high-tech weaponry like the Stryker infantry armoured vehicles and Javelin anti-tank guided missiles (ATGMs) during the wargames.

Incidentally, this will be the largest overseas deployment of the Strykers after Iraq and Afghanistan, coming as the over 200 American soldiers are with 17 of the eight-wheeled armoured combat vehicles.

Costing around $1.5 million apiece, the Strykers come equipped with advanced weapons, CBRN (chemical, biological, radiological and nuclear) protection and C4I (command, control, communications, computers and intelligence) systems.

Indian Army, on its part, has also shown interest in acquiring man-portable ATGMs like the Javelin since the indigenous ‘Nag’ ATGM is still to be operationally deployed.

That’s not all in the current phase of the Indo-US military tango. Mid-way through Yudh Abhyas, yet another exercise named ‘‘Cope India-09’’ between IAF and USAF, will begin at Agra on October 19.

In this primarily transport aircraft exercise, the US will showcase its C-17 Globemaster-III giant military aircraft, among other planes. India has already shown interest in acquiring at least 10 C-17 aircraft and 15 Chinook helicopters after inking the $2.1 billion deal for eight P-8i long-range maritime reconnaissance aircraft and the $962 million contract for six C-130J heavy-lift aircraft with the US.

Q67. Environmental Control Unit / Air Conditioner and APU.
(a) Is the light tank provided with an air conditioner for critical equipment
and crew? Are AC ducts provided to keep crew members and critical
equipment at the requisite temperatures?
(b) Is the AC capable operating in a temperature range of up to + 55ºC?
(c) Is the AC capable of maintaining the temperature in the crew
compartment of the tank to 28±5ºC when working in an ambient temperature
of +45ºC in crew closed down mode?


:(( AC ! 28C comfort ! very un-T72ish....very khanish

is the stryker 105mm tank turret unmanned ?

http://www.military-today.com/artillery/stryker_mgs.jpg

for tracked light tank why dont we get a bunch of refurbished Bradleys from unkil's famous boneyards
which pakis are fond of raiding for useful goodies. we supposedly onlee need 100 tracked light tanks, khan
can provide 300-500 bradleys as the army downsizes into leaner lines.

Does anyone else get the feeling that now that the economy is doing well, the middle men of the IA are flocking at the feeding trough so that maximum number of foreign contracts can be signed? IA seems to be on a buying spree, everything foreign... on a significantly bigger proportion than the IAF or IN.
