    I still cannot believe these are new 1500hp engines, if they were, then they are the best gas turbine tank engines in the world, much better than those on M1.

    So you don't believe Russia is allowed more powerful gas turbine engines than those the Americans use, or do you think the M1 is the best tank in the world still?

    They are putting the vehicle back into production which means it now makes sense to develop a new 1.500hp gas turbine for it, but I would think looking at helicopters that Russia is perfectly capable of having more powerful gas turbine engines that the entire west... look at their helicopters... the biggest US helicopter has three engines and there is a big european helicopter with three engines too isn't there?

    And the M1 has proven to be a corrupt piece of crap just like most other western junk... before being easily destroyed on a modern battlefield the claim was the extra weight and the extra cost were worth it because it was unstoppable and would cut through Russian armoured forces like a scythe through wheat.

    Turns out the US seems to have sabotaged it by sending it in without the full support and training needed to make it operate properly... maybe they want funding for new tanks to replace the ones it uses now.

    Nothing like a scary Russian bear to justify billions for developing new stuff to replace everything...

    Not like they haven't done that before... the BMP-2 and MiG-25 spring to mind immediately.

    For years they said the T-62 and T-64/72 were useless because of their horribly inaccurate smooth bore guns... ignoring the sensible logic that the main anti tank rounds modern tanks fire are APFSDS and HEAT-FS... neither of which actually use spin stabilisation because both are fin stabilised anyway.

    But that is also what was said against T-80.
    It was criticized for the losses during the Chechen wars, when it was used in the wrong way inside an urban environment without other support, apparently without proper armor and with barely trained personnel.

    Like I already said building new T-80 hulls is kind of pointless. If they need gas turbine engines for the Arctic just make a modified T-14 with that 1500hp gas turbine.

    It makes perfect sense to upgrade existing T-80 tanks. But building new ones and continuing to manufacture two wholly different tank hulls just because you have two factories is kind of inane.

    They're not. They are making new powerplants and drivetrains because these are consumables but hulls and turrets they have more than enough to know what to do with them.

    Shiny new engines, probably GTD-1250?

    The Kaluga Engine enterprise revived the late Soviet project "product 39" for the development and serial production of the GTD-1500 tank gas turbine engine with a capacity of 1500 hp. with the possibility of increasing power up to 1800 hp.

    This engine was developed at the end of the 1980s for the further modernization of tanks of the T-80 family, as well as for the further development of a machine codenamed "Object 640" (T-80UM2), created in Omsk in the early 1990s.

    The work on the engine was interrupted after the production of T-80 tanks with gas turbine engines stopped in post-Soviet Russia in the nineties.

    Developments on "product 39" have been preserved, and after the successful use of modernized T-80BVMs on the fronts of SMO in 2022-2023, they returned to the high-capacity gas turbine engine as a promising power unit for subsequent T-80 modernizations .

    Before the war Russia probably had several thousands (up to 5000) T-80B, T-80BV and T-80U. I do not know if all of them could be modernised to the latest standard.

    I suspect the replacement for the T-80 in the arctic will be the DT-30 based two chassis vehicles... there was talk of a new design with a 3,500hp gas turbine engine in one chassis and the other chassis with the custom turret and equipment for the vehicle in question.

    The DT-30 design has an engine in one chassis with a drive train that passes power through the connection which can be angled hydraulically... so for instance if it is in water then it can lift the front cab out of the water and on to a piece of floating ice and and then use the powered connector to raise the section in the water out of the water while moving forward without breaking the ice. Otherwise a single hull vehicle would break the ice as it tries to climb up on to it... essentially becoming an ice breaker rather than a vehicle back on the ice surface.

    This gas turbine model would have electric armour and an electricity based gun like an EM cannon so it would benefit from such a powerful engine.

    The T-80 is an upgrade of existing vehicles designed to use gas turbines and for which new gas turbine engines were designed so any new GTD-1250 or future GTD-1500 would be able to fit.

    I would suspect the T-14 will start out with a 1,800hp engine so any gas turbine version will likely start at 2,200hp or more to be sensible even though the T-14 is not a lot heavier than the T-80.

    Most likely it'll be a Hybrid-Electric T-14 as turbine engines run efficiently at a specific RPM which doesn't suit how tanks are used on the battlefield which are expected to stop and go on a dime.

    Most likely it'll be a Hybrid-Electric T-14 as turbine engines run efficiently at a specific RPM which doesn't suit how tanks are used on the battlefield which are expected to stop and go on a dime.

    Very true, once the vehicles go electric drive then gas turbines are going to shine.

    With engine powered vehicles the engine itself is connected to the wheels via drive shafts and differentials and transmissions and gearboxes, so the effort to turn the wheels is transferred to the engine so the engine needs a lot of torque and sometimes it is doing a lot of work and sometimes not very much.

    As power requirements get bigger the advantage of gas turbines increases because a gas turbine engine is rather more compact and lighter than an equivalent diesel engine.

    You can get very powerful diesel engines like in diesel locomotives and also in ships, but when you scale up the power you also scale up the size and weight and they become very big and very heavy very quickly... but on a train or a ship that does not matter very much.

    If you look at helicopter gas turbines they are working on a 600hp turbine for light helicopters, but their attack helicopters already use 2,700hp engines that are so compact two fit in their attack helicopters. Their Mi-26 helicopter has two gas turbines that generate over 11,000 hp each and it is a big helicopter but the engines are not massive.

    Power stations often use gas turbine engines because if they are generating electricity without being put under load they are actually quite fuel efficient.

    Most APUs (Auxiliary Power Units) on boats and tanks and aircraft are gas turbines because they can be small and light and start up quick and easy and are fuel efficient when it comes to generating electricity.

    When vehicles are electric drive whatever is being used to generate the electricity you will want to be powerful but also small and compact and light and fuel efficient... when you are looking at a tank the ideal solution in the past has been a small gas turbine for an APU and a diesel engine for low fuel consumption and reliability... but that was using the diesel engine to move the vehicle.

    Tanks don't cruise around the battlefield at top speed on motorways and flat hard ground, they tend to try to move from cover to cover so short bursts of very high energy and acceleration and then stop and then accelerate at top speed to move to the next piece of cover.

    You need a very powerful engine which ironically makes the gas turbine an option because it is rather powerful but also rather light weight, but its high fuel consumption operating this way means only two tank families widely use a gas turbine engine as its main engine... the T-80 and then the M1 Abrams.

    It is interesting because I rather suspect the western trend of super heavy tanks has ended and they will be looking at vehicles more like the T-90 than like the Maus.

    However as gun technology moves forward and armour options become available it is likely that power demands are only going to increase with potential laser weapons to shoot down drones, and EM boosted main guns to get enormous muzzle velocities, and of course electric armour for defence and perhaps even camouflage screens.

    One of the advantages of the cage armour is that you can put screens on them and show movies or camouflage to make detection harder or cold dark nights more entertaining.

    T-100: Americans learned about the newest Russian tank, which is cooler than the T-14 Armata, by Maxim Stroker for AvtoVzglyad. 05.09.2024.

    The birth of a new car may happen after SVO.

    Analysts from the overseas publication Military Watch magazine came to the conclusion that Russia is most likely developing a new tank, based on the experience of using its armored vehicles in the Northern Military District zone. The Americans even gave this super-weapon a name - T-100.

    The publication in a foreign military publication about the upcoming Russian T-100 tank is based on the assertion that the experience of using the Soviet main tank T-80 during the SVO made a very good impression on the Russian command.

    Let us remind you that this is the only combat vehicle in service with our army, where a gas turbine unit is used as an engine - as in the American Abrams M1. In particular, thanks to it, the T-80 has a high reverse speed of 25 km/h, which is comparable to similar indicators of NATO equipment.

    For reference: the T-90, considered the best Russian tank in the Northern Military District zone, cannot move backwards faster than 5 km/h. Therefore, when a vehicle needs to quickly leave a position (so as not to receive a “response”, for example), tankers are forced to turn its weakly armored stern towards the enemy. You have to take risks for the sake of speed.

    Military Watch magazine believes that the T-80 was by far the most combat-ready class of tank in the Soviet army. For this reason, despite the fact that it was three times more expensive than its contemporary T-72, the USSR Ministry of Defense purchased it in very large quantities in the early 1980s.

    In the 1990s, amid the collapse of the Soviet Union and a severe economic crisis, the country's leadership, despite the resistance of the military, completely abandoned the T-80, preferring the T-72, which was cheaper to produce and maintain, with its diesel engine. Production of the T-80 was finally discontinued around 1996. And the most advanced version of the T-72 modernization eventually received the name T-90.

    The publication recalls that since the late 1980s, work has been carried out at the Omsktransmash plant, which specialized in the production of the T-80, to transform the T-80 into a next-generation combat vehicle , known as the “Black Eagle”. It was conceptually similar to the T-14 Armata. The latter, according to Military Watch magazine, is produced in small series at Uralvagonzavod.

    The successes of the T-80 during the Ukrainian campaign give the publication’s experts reason to believe that the project of deep modernization of this tank will be revived taking into account the conditions of modern combat. Moreover, the difference in capabilities between the existing T-80 and its future successor will most likely be much more significant than between the T-72B and the basic T-90 Proryv.

    By analogy with the naming of the latter, the authors of the publication decided to conditionally call the tank of the future based on the T-80 the T-100. They believe that it will implement a number of design solutions of both the Black Eagle and the T-14 Armata, since both Omsktransmash and Uralvagonzavod are now part of a single military-industrial conglomerate.
