Boomsticks: Serious boomstick trivia...

The barrel of the 120mm M256 main gun on an M1A2 Abrams main battle tank (just the barrel, mind you, not the whole gun) weighs 2,592 pounds.

My BMW weighs about 2,800.

Yeah, but your BMW can't fire a depleted uranium sabot 2000 yards.

According to Grassroots Motorsports Magazine, you can get your BMW down to the barrel's weight is you remove all the sound deadening insulation and the passenger seats.

I could probably come darn close by 86'ing the power seats and top...

T.Stahl said...

Ah, just compare it to the Rheinmetall 120mm L/55. ;-)

Tam said...

Like the M256, the Z3 is a German design built in America. :)

T.Stahl said...

Well, yes.

And so is the M-Class.
The Saturn V.
The M60 is a combination of German designs, albeit a bad one.
The Abrams is German except for its engine, some claim.

BTW, what is "86'ing"?

comatus said...

to 86 (transitive verb): to drop unceremoniously, round-file; to shit-can.

Source, either the address of an often-raided NY speakeasy, or the form used to delete a memory scheme item in the post office.

BMW started making cars under English license. To get even, a German designed the Triumph twin.

shamelessly lifted from Fr Frog's page on ballistics comes this bit of not-so-trivial trivia:

KE of the M829 APFSDS-T (Armor Piercing Fin Stabilized Discarding Sabot-Tracer) 120mm round. It throws a 9.41 pound (that's 65,870 grains), 1.06" diameter, 31" long, depleted uranium dart at 5480 f/s from the 120mm M256 smooth-bore tank canon on the M1A1 and M1A2 tanks.

Lets see now -- KE (ft lbs) = (W * V²) / 450240. That gives us (65,870 * 5480 * 5480) / 450436 which boils down to (hold on to your hats!) 4,391,500 foot pounds (that's right 4.3 MILLION ft lbs).

Whoooeffingwaa!

My Z3 coupe with a 3.0 liter in line V6 was not even in British designers wet dreams when they made the Triumph.

I want me one of those inline V6's. ;)

T.Stahl said...

Well, there are VR6's, which are kinda like "inline V6's" (at least that'd be the literal translation of the German abbreviation VR).
In fact they are V6's with a 15° angle between cylinder planes and one cylinder block instead of two.

Two banks of cylinders breathing through the same cylinder head just ain't natural.

T.Stahl said...

Well, it IS a chimera. What d'ya expect? ;-)
