The T-62 is the forgotten Soviet Tank. There doesn't seem to be any information about its variants and there doesn't seem to be any agreement on them when there is information.

 

Any information on T-62 history and variants?

Tell me about it. I haven't heard much about Syrian T-62s.

 

Then again, there isn't much news on Syrian armour at all....

 

Unedumacatde me says that the T-62 is more of an evolution of the T-55. :unsure: I'll shut up henceforth. :lol:

It's rather a Soviet panic reaction to the crisis of T-55 increasingly falling behind the threat armor while the new tank (what would become T-64) was being delayed and delayed and delayed.

This reaction was apparently caused by the defection of a M60A1 and it's crew from Iran to USSR. The tank was tested and it was found that the 100mm gun had quite a bit of trouble to penetrate it (frontally). It is noteworthy that the T-62 was the first tank to introduce a smoothbore gun, the 115mm 2A20 gun.

Why wasn't the T-62 as widely exported and produced in other WP Countries as the T-54/55?

I once read that they weren't at all happy of the model and preferred to keep their 55s, but don't know if it's true.

from FAS

 

T-62A: Besides the standard 7.62-mm PKT coaxial machine gun with a range of 1,000 meters, the T-62A version features a 12.7-mm DShK antiaircraft machine gun with a range of 1,500 meters against ground targets and a slant range of 1,000 meters against aircraft. The T-62A also has a stabilized main gun, which enables the gunner to track and fire on the move with significantly improved accuracy.

 

T-62K: Command tank models also have a land navigation system which includes a gyroscopic compass and a calculator giving continuous enroute readout of the tank's location (in relation to its point of origin) and its distance from and azimuth to a predetermined objective.

 

T-62M adds protection, FCS and ATGM capability.

 

T-62 variants with a V-46 T-72-type engine add -1 to their designation.

 

T-62M1: Variant with Volna FCS but no missile launch capability.

 

T-62D: Variant with the Drozd APS vs ERA.

 

T-62MK: Command variant.

 

T-62MV: Version with ERA in place of the bra armor. The ERA includes Kontakt ERA and Kontakt-5 2nd-Generation ERA.

 

From wikipedia

 

T-62 - early production version, had a 14.5 mm KPVT machine gun in coaxial mount instead of the more common SGMT 7.62 mm.

 

T-62A - Added 12.7 mm anti-aircraft machine gun (which is often removed in the field) and changed coaxial machine gun to PKMT 7.62 mm. Also added was a stabalized main gun which let the gunner fire while moving with significantly improved accuracy. Though still when firing ATGMs from the gun it would need to make a quick stop. All T-62s in Soviet service were converted to these specifications before 1970.

 

T-62K - Command tank with additional communications gear, recognizable by multiple radio antennas instead of just one.

 

T-62M - added laser range-finder, reactive armour.

 

T-62D - added 9K118 Sheksna laser-guided antitank missile system (AT-12 Swinger), which is fired through the gun tube.

 

T-62MV - T-62D produced for export, most of which were given to North Korea and Syria as military aid.

 

From militaryfactory.com

 

T-62 - Base production vehicle

T-62K - Commander's Vehicle

T-62 This is the basic T-62 model, which essentially was a stretched T-55 chassis, with a new suspension, and a new turret equipped with the U-5T (2A20) Rapira 115-mm smoothbore gun. The gun has the new Meteor two-axis stabilization system.

 

T-62K This is the command tank variant of the T-62, and like earlier types, has one additional R-122 radio, a TNA-2 navigation system, a 4-meter antenna, but less ammunition. The corresponding command tank for the T-62M is the T-62MK.

 

T-62M (Also called T-62A) This tank includes the addition of a 12.7-mm antiaircraft DShK machine-gun on the loader's hatch. This modification included modification of the turret right side.

 

T-62M Model 1975 This is the T-62M with the addition of the KTD-1 laser rangefinder over the main gun mantlet.

 

T-62E The war in Afghanistan forced the Soviets to up-armor their tanks to provide better protection from infantry antitank weapons, such as the RPG-7. This upgrade led to the BDD appliqu? armor package. This package consists of a panel of armor on the glacis plate, two panels of "horse-shoe" armor around the front of the turret, and an optional package of belly armor for anti-mine protection. The total package adds 3.9 tons to the weight of the vehicle.

 

T-62M1 This further modification of the T-62A includes much of the modifications added to the T-55 to make the T-55AM2PB. These improvements include the Volna fire control system with the BV-62 computer, Meteor M1 gun stabilization package, TShSM-41U sight, KDT-2 laser rangefinder and 1K13 guidance sight package. This tank is equipped with the AT-12 Sheksna laser-guided antitank guided missile, which operates in much the same way as the AT-10 STABBER ATGM. This tank also includes the uprated V-55U engine, and the R-173 radio system. This vehicle is also usually fitted with the BDD appliqu? armor package.

 

T-62MV This is the T-62M fitted with the ERA package found on the T-55MV.

 

 

Russian source I think is most accurate.

The T-62 wasn't worth the difference in price (40% IIRC). Bojan posted a comparison performed by the yugoslavians in the 1970s between the T-62 and T-55. The gun was ok but the ROF was low, protection was a bit better but not decisively. With good ammo the T-55 was ok to soldier on.

Nope - all of those are badly copied ancient Janes, with one from Wikipedia being expecial rubish...

The designation I have posted are probably best you can find on the english part of the net.

Nope, if you check dates of Iranian M60A1 introduction to service you might note that it does not compare well to a T-62 inroduction to service (1961.)...

 

The tank was tested and it was found that the 100mm gun had quite a bit of trouble to penetrate it (frontally).

BK-5M HEAT would penetrate w/o large problems.

 

It is noteworthy that the T-62 was the first tank to introduce a smoothbore gun, the 115mm 2A20 gun.

 

1st serial tank.

No, it was much worse than that. 100mm gun, using the AP ammo (all that was available at the time) couldn't cope even with with M48. 100mm HEAT rounds of the time could, but were not reliable and not available in sufficient numbers. On the other hand, while T-55 could marginally cope with 90mm hits, 105mm L7 gun hopelessly overmatched it, which made the problem of weak ammo even worse, and it was already determined that L7 will become a NATO-wide weapon. So long before M60A1 there was already a crisis that needed urgent solution, and that, at the time when Khrushchev effectively killed off armor development.

Was the T-62 much better at coping with the 105mm gun? the protection in the hull was similar (and somewhat higher in the turret).

It was better protected not by heavier armor, but by *much* longer reach of its armament. As you may realize, the two aspects go hand in hand. The Soviets believed T-55 firing AP ammo can only defeat lower front hull of M48, and even that only at 1200m. T-62 on the other hand could defeat M48 anywhere far beyond 2000m. In fact even M60 would be defeated beyond 2km anywhere except the glacis. This represents a major increase in capability.

OK, I see what you mean. The T-62 gun also was much more accurate, especially below 1500 meters. The 100mm gun would start having trouble at 1000 meters.

What was a problem with Soviet use of 100mm HEAT?

Those (BK-5 and BK-5M) sold to Yugoslvaia in 1961. worked w/o problem and with decent penetration...

Those were also reasonably well available, T-55 having 15 (later 18-20) in combat load...

What was a problem about poor availability? Price?

Bojan, there was a T-62A (not to be confused with the other T-62A/M, that mounts the 12.7mm AAmg) that was armed with a 10mm T-55 gun? I assume this was some kind of prototype.

 

What sources are your information from?

 

It seems Bulgaria was the only Warsaw Pact nation to accept the T-62 into service. Any more info on numbers and introduction dates? or anything else? I've red one account from a Bulgarian tank crewman who wrote he was "in a t-62" during the 1968 intervention. Its suprising to me that Bulgaria should have gotten such and advanced tank, for its time, so early. Since, generally Bulgaria recieved older and not upto date soviet equipment.

The gun was 100mm in caliber, but it was completely different from the T-55's gun, more or less in 105mm L7 league.

I wrote "10mm" that was a typo. I did mean 100mm. I thought it was the D-10. Never heard of the D-54. never entered serious production?

It was a very good gun that had about same performance with KE round as 115mm. However the HEAT round was both worse and more expensive. But what really doomed the gun though was that Khrushchev loved the 100mm T-12 ATG that was shown to him ("1575 m/s, is it cool or what?!", literally) and demanded that new tank has a smoothbore. T-12 wouldn't fit so they basically rebored D-54.

Khruschev critisised the generals in many occasions. According to him they were obsessed with tanks, which were made obsolete due to the development of missiles. The heavy breaktrough tanks were the main objectives of these critics.

Argh, do you realy understand anything? T-62 with AAMG is not T-62A/M - it uses same T-62 designation as base model.

100mm D-54TS gun. It is Object 164, and it was not quite a prototype - it was actualy acepted to service in 1962. but was newer produced - sources disagree why, but there is a theory that new AP(DS?) projectile for a gun was not finished in time, other being that gun designer fell out of favour...

Yes, Bulgaria used T-62s, but IIRC they got them in '80s... At one moment they converted all remaining in the recovery vehicles (TV-62M designation IIRC).
