    [quote="GarryB"]
    Soviet T-62 tank, firing from (smoothbore) cannon at a range of 1000 meters against a target moving 19 km/h, was rated to have a first-round hit probability of 70% when firing a kinetic (APFSDS) projectile.

    Under the same conditions, it could expect 25% when firing HEAT round.[7] This affects combat on open battlefield with long lines of sight; the same T-62 could expect a 70% first-round hit probability using HEAT rounds on target at 500 meters.

    The [7] suggests a note, how about letting us see that quote?

    7.^ Jane's Armour and Artillery 1981–82, p. 55.

    The gunners sight is not wielded to the main gun... the gunner can continue to follow the target... the gunners sight is able to move independently from the gun barrel, and even the T-62 has two plane gun stabilisation and a stabilised gunners sight...

    We are not talking about moving 60 degrees to reload and then having to move 60 degrees back to fire...

    The T-62's main gun is the 115mm U-5TS smoothbore. Because of the length of the shell, the main gun elevates after each recoil. This, coupled with the complicated fire control system, means the tank can maintain a rate of only four to five rounds per minute, as opposed to Centurions 10 r/m.

    Also, the turret cannot be traversed during the loading sequence. This combination of drawbacks made the T-62 particularly vulnerable to Israeli tanks during the 1973 Yom Kippur War and the 1982 invasion of Lebanon.

    The 115mm 3BM-6 APFSDS-T has a muzzle velocity of 1,680 m/s and its maximum effective range is 3,000 m, although most accounts of effective combat range mention 1,500 m. The official direct-fire range against a target 2 m high is 1,870 m, while against a 3 m tall target it is 2,260 m.

    And guys, iam sorry i was offensive and abit abusive, but to call my writing HEAT inferior in hit probability vs APFSDS for Rubbish sent me spinning. You really should have said you meant a specific round and year. welcome

    Sorry, but I think modern sources of information based on real inside knowledge are rather more valuable and believable than western estimates from the early 1980s where most "information" was estimate and guesswork and mainly opinion.

    The T-62's main gun is the 115mm U-5TS smoothbore. Because of the length of the shell, the main gun elevates after each recoil. This, coupled with the complicated fire control system, means the tank can maintain a rate of only four to five rounds per minute, as opposed to Centurions 10 r/m.

    As I said above... rate of fire is only part of the puzzle and is really only important if you intend to miss a lot.

    Rates of fire are relative... even with a rate of fire of 20 rounds per minute does that mean the tank will even see 20 targets worth shooting at and engage them all in a single minute?

    Most tank tactics I have read about involve moving from covered position to covered position... firing and then moving... where possible moving through dead ground with no line of sight of the enemy to another position to fire from.

    Also, the turret cannot be traversed during the loading sequence. This combination of drawbacks made the T-62 particularly vulnerable to Israeli tanks during the 1973 Yom Kippur War and the 1982 invasion of Lebanon.

    And yet they were happy to use captured T-62s themselves... that is a bit odd isn't it?

    The 115mm 3BM-6 APFSDS-T has a muzzle velocity of 1,680 m/s and its maximum effective range is 3,000 m, although most accounts of effective combat range mention 1,500 m. The official direct-fire range against a target 2 m high is 1,870 m, while against a 3 m tall target it is 2,260 m.

    These facts are empty.

    I would assume that these are the results of Israeli testing of captured tanks and captured ammo, which is unlikely to be that much like Soviet tanks and Soviet ammo.

    How can we tell how accurate Soviet HEAT rounds are based on Israeli results with Arab tanks that may not have even been issued with Soviet standard HEAT rounds?

    I have a very low opinion of JANES... except their articles on SAMs written by a certain American expert (SOC).

    They like to cut and paste... for several decades the Stechkin was a heavy obsolete weapon that was not effective, yet from every Russian source it was a highly desirable and effective weapon, yet even in the 1990s it was the same entry... heavy and obsolete and the writer couldn't understand why such a backwards and useless weapon was in a modern army. No comments when HK VP-70Z pistols and Glocks with 3 round burst fire capability were developed, or when various machine pistol replacements for the Stechkin were revealed.

    And guys, iam sorry i was offensive and abit abusive, but to call my writing HEAT inferior in hit probability vs APFSDS for Rubbish sent me spinning. You really should have said you meant a specific round and year.

    My apologies... For much of my life I had very little access to Russian sources and not being able to read or speak Russian I have relied on translations and interpretations from western experts who now seem to have had the mantra that if it sounds too good to be true it is propaganda, and if it sounds bad then it must be the truth. Therefore heavy ERA that will stop APFSDS rounds is a myth and the T-64 eats the arms of 10 tank gunners before breakfast every day is truth.

    The other myth is that the way the west does things is the right way and therefore anything the Russians try that is not the wests way is wrong... the west loves APFSDS rounds so if the Russians perferred HEAT for a while then they must be wrong.

    Equally the west has invested a lot of time and money in solid rocket fuels for ballistic missiles, so if the Russians are making liquid fuelled missiles it is because they are backward or have some problem. of course this ignores the benefits of liquid fuel... cheaper, more powerful, fully storable for the life of the missile just like solid fuel... and allows the much easier and safer handling of empty missiles with fuelling in place.

    Well, its no drawback to being able to have 20 tanks firing 10r/min, makes 200r/min against a 20 strong force of tanks which fires 4r/min, makes 60r/min. Other factors are of course detection, battlemanagement and hitting. But with 200 vs 60 r/min, thats certainly an advantage.



    And yet they were happy to use captured T-62s themselves... that is a bit odd isn't it?
    Not really, they modified it, removing the 115mm for the 105mm. Called it Tiran 6,and enhanced armor protection. I dont however know if the reload sequence with a non moving turret during reload was changed.

    Agree, the West has always underestimated russian arms, as did Hitler, and he paid the prize.
    But still, some arms hasnt been a succes, and the T-62 is one of them. In case of western arms there has also been less succesful machines. The M551 Sheridan for example, is probably amongst the worst tanks/IFV´s ever imposed on an army.

    I standby my opinion that the T-62 wasnt a succes, the 115mm gun was.

    They kept plenty of T-62s with 115mm - plus the 105 conversion is obviously due to ammunition standardization, not really performance.

    Also, not all 105mms are the same Wink .

    Comparing T-62 to Sheridian is absurd.

    T-62 served successfully in many wars, was respect by its opponents, when properly used did very well, served WELL past its time, and was produced in massive numbers.
    Like I said, its like calling every Western tank a failure, since many of them had even worse armor.

    Rate of fire to a tank is like rate of fire to a sniper.

    Unless you are get caught in a time warp or are intending fighting thousands of Chinese tanks then rate of fire is not that important.

    Modern tanks have very large rounds which limits the number they can carry at once. The winner wont be the vehicle that fires the most, it will be the one that hits accurately first.

    Not really, they modified it, removing the 115mm for the 105mm. Called it Tiran 6,and enhanced armor protection. I dont however know if the reload sequence with a non moving turret during reload was changed.

    Actually they evaluated the 115mm gun as being very good and kept them till their supplies of captured ammo were used up before replacing them.

    I standby my opinion that the T-62 wasnt a succes, the 115mm gun was.

    Well then, you would have to ask yourself why they are only withdrawing them now. You'd also have to ask why take them to Afghanistan, why take them to Georgia?

    The Sheridan was not a great tank, but it was an adequate tank in comparison with other tanks operated by air borne forces.

    The thing that ruined the Sheridan was its gun/missile system.

    The huge irony of course is that the Sheridan made the top 10 worlds best tanks on the History channel, which just goes to show how biased and one eyed western experts really are...

    I standby my opinion that the T-62 wasnt a succes, the 115mm gun was.

    I will respect your right to that opinion even if I disagree.

    I didnt. I said the T-62 wasnt a succes, but it was a well balanced tank for its time, the Sheridan however was a huge failure.

    Agree, modern tanks. Although it wont be a disadvantage to be able to fire quickly rather than slowly.

    Yes, and they also uparmored, changed engine and radios, so it was a good tank, not great, but good.



    Well then, you would have to ask yourself why they are only withdrawing them now. You'd also have to ask why take them to Afghanistan, why take them to Georgia?
    As a well balanced tank of its time, it could certainly do the job as fire support against gerillas. And vs Georgia it was attached to motor rifle brigades, also in the role of infantry support. I dont think they wanted to go tank battling with T-72s.





    The huge irony of course is that the Sheridan made the top 10 worlds best tanks on the History channel, which just goes to show how biased and one eyed western experts really are....
    Totally agree, it would be much more interesting to see a Russian version of top 10 tanks..


    I will respect your right to that opinion even if I disagree.
    And i respect yours, maybe we should start a new thread on T-72 and see if we can brawl some..

    All other things being equal a high rate of fire is not a bad thing.

    It is just not the most critical feature.


    Yes, and they also uparmored, changed engine and radios, so it was a good tank, not great, but good.

    The engine change and radio change is perfectly normal... using your own engines and radios makes them more compatible with your logistics train.

    And vs Georgia it was attached to motor rifle brigades, also in the role of infantry support. I dont think they wanted to go tank battling with T-72s.

    They had plenty of newer tanks available if they feared Georgian T-72s capabilities with their Israeli upgrades.

    Totally agree, it would be much more interesting to see a Russian version of top 10 tanks..

    Would actually rather see the top x tanks from country y for a range of countries... Britain, France, Germany, Russia, US, etc etc.
