How much fuel, ammunition, spare parts et cetera come with them? Tanks
are logistic-hungry beasts and need more support than most imagine.
Flying in a tank or three isn't that much help if you end up with an
immobile pillbox two days later.

Clearly a tank that weighs 70-75%% as much as a Western Tank and has 3
crew instead of 4 would tend to require 25% less fuel,

Why? Fuel consumption at idle (where tanks spend most of their time)
would be similar if diesel-engined: for that matter, the inability to
explain "idle power" to a gas turbine doesn't scale down much either.

Doubling the horsepower of a typical automobile doesn't usually double
the fuel consumption. Increase it yes, but not in direct ratio.

The superior fuel consumption of a 45 ton tank as opposed to a 63 ton
tank derives from the lower mass of the former.

Diesel engines are more efficient at both the high power range and
when near idle. In fact when opperating at low power levels or near
idle gas turbines are particularly inefficient compared to diesels.
Modern hyperbaric diesels don't give up anything in engine power to
weight ratio or size either. Only noise is an issue and the smoother
power of the turbine provides for better track grip.

A 45 ton tank with a hyperbaric diesel should consume 0.75 x 0.75 =
56% as much fuel as a 60 ton gas turbine vehicle.


less tankers,

Irrelevant - you've got so many warm bodies to feed and water that
removing a handful doesn't matter. (You *did* have supporting infantry
for these tanks, didn't you?)

A squdron of M1A2 Abrams needs 20 tanker trucks to support it and a
Leopard 2 needs only 15.

I hardly think the food consumption of the crew will match their fuel
consumption in weight.



less spare track,

Why? Track life will tend to be similar, and generally long enough that
airlift won't be crucial.

smaller recovery vehicles.

Which are still large heavy vehicles needing C-17 lift, whether they're
recovering Western or Soviet designs.

Sure, but that doesn't fix the catastrophic ammunition explosion
problem, or the hideously cramped interiors.

The Soviets field two completely different tanks: the T64 (not to be
confused with the T62) and the T72. The T72 was meant to be a cheaper
less capable tank for export. As it turned out the T72 was exported
in a degraded form while the also produced in greater numbers in a
higher standard forms for Soviet use becuase it was cheaper than the
T64 (which is superior and is deployed)

And the T-64 is more comfortable for Western-sized crews to operate for
sustained periods of time?

The soviet tanks do have multilayer composit armour as thick and heavy
but apparently less capable, night vision systems, gyro-stabalisation
etc. All of these could be brough up to western standards.

Sure, just throw enough money at it. That's the problem - you end up
spending more money to get to where you already were before.

No. The fire control system is merely an electronic device. It works
as well in 45 ton tank as a 60 ton tank.


The tanks are lighter, faster, require less logistics and manpower,
more easily transported and ultimetly more mobile and make smaller
targets.

Unfortunately, they've demonstrated a persistent inability to outfight
their Western counterparts.

First of all we have never seen contemporary Western tanks battle
against up to date Russian tanks. Iraqi T72s were even downgraded
with less armour and were forced to fire steel penetrators.

By this time Russians were fielding T80 tanks with composit armour.



And a bloody useful one.

True but overcome in the T80UM2 black eagle. Admitedly this tank is
not deployed but it shows that the two main issues: seperate magaine
and a restricted gun depression can be overcome within the
Russian/Ukranian philosophy.

How well does a six-foot crewman fit into the T80UM2 and how well can he
man his position buttoned-up for 48 hours? (This was an acceptance test
right back in the 1960s for Chieftain...)

Confort is less but has been improved in the Black Eagle version of
the T80.


So, you're talking about "Soviet tanks blessed with all the advantages
of Western technology"? Except that the crews would mutiny if you tried
to use Western professionals...

The problems can be overcome.

Certainly. Is it cost-effective to do so compared to the alternatives?

I am talking about using Russian tank designe philosophy in an
entirely western designe as opposed to modification to existing
Russian hardware with western systems.


Why? Still not designed for survivability or crew endurance, which are
key factors for how the West fights.

The magazine is the main issue in survivablity but the smaller tank is
less likely to be hit. A lighter tank means you could have possibly 4
tanks in theater as against 3.

They'll shoot off more ammunition (four tubes rather than three)

That's a good thing.


and burn off little less fuel, and still come in one per airlifter.

Clearly a C5 could carry two 42-45 ton tanks and struggle with a
single 63 ton tank.

A C17 could bring a 45 ton tank along with additional support
vehicles.


So, if
you pursue this option... why bring in four tanks that keep losing
fights, when you can bring in three that keep winning?

They won't be loosing fights. Despite being 45 tons their armour is
of the same protective value.


Or you can take the losers and spend a lot of money adapting and
improving them... but why bother when you already operate the winners?

In some cases it means having a few
tanks at all instead of none at all and in some cases it means not
having to hold an advance to let your logistics catch up.

If you're trying to do an armoured advance based on airlift, you're so
screwed before you start that the choice of tank is irrelevant.

Its not just airlift but other aspects of mobillity and logistics that
are effected.
