well in a james bond movie as the struggling C130 roars over the afpak border, he does sit inside the jeep, trail out its parachute and lands safely as the jeep gets pulled back. he then drives to peshawar or karachi per a road sign. :rotfl:

very tfta and stiff upper lip onlee.

Hi

Can somebody ID whether this is tank-ex? If so, are the sloping armour a new addition. Is this a new version by any chance?

nice pic... was there an article along with it??? If so could you post it too???

neeraj · **Posted:** 05 Nov 2009 05:16 pm

Does the full tech transfer for T90 include engines as well.
Is the tech transfer enough for making T-90 from raw materials or do we still end up relying for parts from Russia.
Thanks

Those look like BMPs to me. Definitely not Arjuns.

Not so fast saar..Soviets did precisely that (Low level airdrop, crewed BMP)! Please google 'REACTAVR'

most APCs/tanks look similar from a distance, not talking of this picture where the profile is clear.
one way to be sure is counting the number of wheels.

Gagan · **Joined:** 16 Apr 2008 04:55 pm **Posts:** 1410

Only the arjun has 7, the T-55s, T-72, PT-76 and the BMPs have 6.

PS I've used this formula in the early days, now of course there are so many more things one can recognize.

if it's close enough it's usually obvious, you don't even know which particular feature did the identification. you just look and know.

A Quick Guide for Differentiation.

The following should be seen:

(a) Size and shape. The APC will be smaller than the tank and will have a flat rear in the hull. The turret will also be small.

(b) Turret. Tanks will normally have a overhang at the rear of the turret.

(c) Number of bogey wheels.

(d) Length of the gun.

Thats pretty neat work; whoever did this please do the orthographic projections as well as a wire frame model based on the above drawing (may be these were inputs for the above drawing but I then I could be wrong) .We can then use the same technique for most of the indigenous platforms and use them on BR webpages. :wink:

We are in some good shape viz-a-viz Armour today due to local production of T-72 and BMP-II. IMHO this production run was not under license from Russia. Thank fully mine protected vehicles are also being produced locally.

Though this production could easily have been Abhay.

That increase in BMP-II production is likely to be in line with news of raising of new Mechanized Regiment Units and conversion of more Infantry Divisions to RAPID modification.

Indian Army to deploy more troops along Arunachal border

India is quietly beefing up its defences along the China border in Arunachal Pradesh, even as it publicly downplays the growing diplomatic spat with Beijing over the Dalai Lama’s visit to the state.

The Indian Army will deploy its new 15,000-strong 56 Division in Arunachal, which China claims as its own, within four weeks, a senior defence official told HT, requesting anonymity.

Simultaneously, it has put out a Request for Information (RFI) for acquiring 300 lightweight tanks that can be deployed in the North East and Jammu & Kashmir.

The purpose is to leave nothing to chance, notwithstanding the show of bonhomie between Prime Minister Manmohan Singh and his Chinese counterpart Wen Jiabao at their October 25 meeting in Thailand.

A second division will be deployed in Arunachal Pradesh in the next 12-18 months, the official added.

The army’s RFI states the light tanks should be capable of destroying bunkers and soft-skin vehicles up to 3,000m away and should have armour-piercing anti-tank guided missiles and anti-aircraft machine guns.

The RFI, which is in HT’s possession, also stipulates these tanks should “have protection against nuclear, chemical and biological warfare”. :roll:

In recent months, India activated three airfields along the 646 km Line of Actual Control (LAC) with China, last used during the 1962 war with China. The army and the Indo-Tibetan Border Police have also stepped up patrolling along the

is there such an animal that can already do all those things or is theis a way to throw a RFP and say waiting for reply?

Rahul M · **Posted:** 11 Nov 2009 10:58 pm

they are not asking for the moon in this case. ability to work in NBC environment is standard capability these days. all the IA's current armoured vehicles can do that.

the other requirement is more interesting. note that it doesn't mention APFSDS rounds as a requirement.
to fire bunker busting rounds (HESH rounds) would require rifled main gun like the arjun, while the technology is not unachievable, I wonder how many designs are in production today.

I always didnt quite get that.

It is logical that to fire HEAT or APFSDS, we *need* a smoothbore (HEAT case because rotation will disrupt the shaped charge and APFSDS because of velocity and fin stabilization--ofcourse slip rings were successfully used), but why does HESH *need* a rifled gun ? It cant be just accuracy, because then does it imply that APFSDS and HEAT can be "less accurate" ?

The Q is simple, with computerized FCS, why cant HESH be fired from a smoothbore ?

rahulm,

weren't you gonna post something about arjun's firing comment from your recent trip ?

negi · **Posted:** 11 Nov 2009 11:47 pm

As per Wiki

1.

Quote:

HESH rounds are thin metal shells filled with plastic explosive and a delayed-action base fuse. On impact, the plastic explosive is "squashed" against the surface of the target, and spreads out to form a disc or "pat" of explosive. A tiny fraction of a second later, the base fuse detonates the explosive, creating a shock wave that, owing to its large surface area and direct contact with the target, is conducted very effectively through the material.

later

2.

Quote:

The round has good general purpose use being effective against most targets, though the round is generally used at relatively lower velocities because high velocity excessively disperses the pat of explosive

Probably the spin imparted by a rifled barrel helps to achieve '1' (i.e. uniform spread of the the plastic explosive under centrifugal forces) and '2' is again better achieved by employing a rifled barrel (smooth bores impart a high muzzle velocity for same amount of charge propellant).

Rahul M · **Posted:** 11 Nov 2009 11:50 pm

cy, that's senior rahulm, not me. (in case you mixed up)

anujan, I don't know, may be it can be done with current tech. as for the sabot rounds, I guess
/guesswork alert
the high velocity means that even in case of inaccuracies, the spread at point of impact due to external factors (crosswind etc) won't be appreciable.
/guesswork alert

May be Indian desire for light tanks is for equal footing in N and NE sector wrt Chinese.
PTL02

Quote:

The main armament is a 100mm high-pressure, low-recoil smoothbore gun developed from the Type 86 towed anti-tank gun. The gun can fire armour piercing fin stabilised discarding sabot (APFSDS) with tungsten core, as well as HEAT and HE rounds, with 30 rounds carried onboard the vehicle. Fire accuracy is attained by a primitive Type 37A light-spot fire control system with night vision and laser rangefinder input.

Quote:

Another reason for the declining use of HESH rounds is the switch by most armies to smoothbore cannon, since a HESH shell relies upon spin for accuracy.

Regarding the Arjun:

Other points. Since I know these people very well, I challenged them (pre-fixed by an "*").

All in all, it would appear, from my limited interaction, the Arjun is gaining (slow) acceptance The feeling I get is aside from the specificaitions (GSQR) its a leadership issue more then an Arjun per se issue.

On another note, without exception, so far, all the fauji's I have interacted with have been surprised and bewildered at the interest a non fauji is taking and more importantly on the (limited) knowledge during interactions.

Most expect interaction at a very superficial leveland get visibly taken aback as the conversation progresses. Most are happy that a non fauji is taking such interest. A few get upset. Which brings us nicely to the larger issue of fauji- civilian relationships and the expectations from the civilians. I will post later in the Army thread.

Please note: Nothing I I post anywhere is the official view.

Indian Army to acquire 100 Armoured Personnel Carriers

Over a period of five years, the Indian Army is looking to add over 500 new APCs to its existing fleet of around 1,500 Russian-origin BMP-I and BMP-Iis, Defence Ministry sources said.

Currently, the Indian Army has 26 mechanised infantry battalions with its APCs having the capability to carry around 10 soldiers each.

Some of the APCs are equipped with missile launchers for firing Anti-Tank Guided Missile (ATGM).

The Army wants its new APCs to be capable of being air-lifted in IAF heavylift aircraft such as the IL-76 and C-130Js to be procured from US in the near future.

The new APCs should also be capable of being carried in Navy's amphibious warships such as the INS Jalashwa and the INS Airavat.

I hope they place order for more Arjuns. At least for Mark II.
Anyway it is nice to read the good change of attitude towards desi products.

Absolutely.. Its a broad brush, but what the heck. The old set is too foreign-goodies enamored.. Buy this that and everything else.

Until the new crop of people who have played and nurtured Arjun don't take over, t-90's will continue to be the main MBT's and buy foreign will remain the only mantra.

This is very common. Youngsters appreciate your taking interest and having some knowledge, older & more senior guys get quiter, till you get them extremely comfortable. All service men are encouraged not to talk or comment on anything defence. In India, everyone takes the official secrets act way too seriously.....including some who should not be.

I have also noticed that many of the IA folks I have interacted with do not seem to have a lot of information on systems in use in other parts of the world. Not sure if this was co-incidental, or in keeping with the "keep quite" ethos of services. Not sure if comparative weapons and equipment is covered in internal training - Seniors can enlighten...RayC sir ?

I agree that many are not concerned about the world military equipment, but those who are assigned to do so, do and it not confined to AHQ!
