Do you think this vehicle has to stop for traffic jams?

[Oleg Volk]

90mm self-propelled cannon. Anyone got history on these?

 

[TallPine]

Hey, the perfect rig for road hunting!

Do you suppose there could be a saboted bullet for mulies and whitetails?

Something like 180 grains at 25,000 fps ....?

 

[QuarterBoreGunner]

Oleg-

I've no idea what traffic is like in Nashville... but here in the San Francisco Bay Area... oh baby. Sign me up. Slap some turn signals and brake lights on that sucker.

 

[Art Eatman]

Aw, that cannon's too noisy! Gimme a late model D-6 with a tilt blade...

, Art

 

[BlackJack]

Turn signals and brake lights?????

We don' NEED no stinking turn signals and brake lights!!!!!!!

 

[Byron Quick]

All your traffic jams are belong to us!

 

[280PLUS]

i'd say,,,

if it stops for traffic jams, it would only be long enough to reload...

thats a pretty light carriage for a 90mm

The T71, M36, M36B1, M36B2

This was an attempt to install the 90mm gun in a M10. The initial test was a failure in that the gun made the vehicle unstable and the weight made for a poor ride. A large hollow bustle was designed for placement at the rear of the turret to act as counter weight to compensate for the gun. The counter weight made the vehicle a success at this point and was thus named the T71 (when based on the M10A1 chassis powered by Ford it was called a T71, it was the T71E1 when powered by GM). Vehicles returned to the factories and those already in production were upgraded to the T71 standard. In July 1944, the vehicle was standardized as the M36. In the Fall of 1944, GM began producing a variation of the M36 using the M4A3 chassis. This became known as the M36B1. The 90mm main gun could penetrate 6" of armor at 1000 yards, and with 2 rounds, penetrate 5' of concrete.

The M36 became very popular because of it's firepower and protection. This popularity resulted in it being often used in the role of a combat tank rather than just as a tank killer. The drawback was the open top. In the Spring of 1945, this was corrected and an add-on shield was issued.

Production quanities are as follows:
M36 - 1413
M36B1 - 187
M36B2 - 724

 

[Tamara]

It's probably a low-recoil 90mm, like the Cockerill or something similar.

 

[MLH]

Tamara?

You mean you don't own one(or two) of those?

The M56, also known as SPAT for Self-Propelled Anti-Tank, was designed as an airborne anti-tank gun. The 90mm gun M54 was ballistically identical to and used the same ammunition as the M36 90mm gun in the M47 tank, and it was fitted with a blast deflector. The M56 was unarmored, and consisted of little more than a gun mounted on a tracked aluminum alloy carrier. There was a small blast shield fitted to the weapon, and this had a windscreen in the left side for the driver to look through. Creature comforts were nonexistent as the vehicle was completely open. The commander sat on top of the radio, and the loader's seat was on top of the right fender stowage box, leaving the gunner and driver as the only crewmen "in" the vehicle. The tires on the M56 could run flat up to 15mi (24km) at up to 15mph (24kph). The ammunition rack was located in the lower rear hull, and the loader was provided with a folding platform from which to feed the gun.

[gun-fucious]

heres a little more history:
http://members.aol.com/sturmpnzr/SPAT.html

 

[twoblink]

It looks like the perfect vehicle for the 405FWY in LA, at 5pm on a Friday afternoon.

90mm huh? So I can shoot through what, 10 lowered honda civics with one shot?

 

[Okiecruffler]

Looks like the perfect vehicle for someone who is trying to compensate for shortcomings elsewhere. Where do I get one?

 

[glockten]

Oleg,

Is that the one in front of the American Legion post in Donelson?

 

[4 eyed six shooter]

Kinda looks like my Blazer.
Now if I could only get that gun on top.

 

[makdaddy03]

To answer your question.

NOPE.

 

[Darrin]

Are those surefire's on the front or just headlights?

 

[Moparmike]

Why is the first thing I think of the movie "Goldeneye' where Q is telling 007 that he "has a license to kill, not to break the traffic laws..."

Looks like the perfect ride for downtown Fayettenam. Like to see some socialist snotrag tell me what I cant do with that... (J/k, i would never do something like that while it was illegal...)

 

[garrettwc]

Hey cool!

Runt got some new wheels!!

 

[El Tejon]

I don't think that would work here in Orange Barrel City. The rap music and dust could still get to the crew.

I'll stick to my surplus Iraqi T-72. Never been fired and only driven to Syria in reverse.

 

[Oleg Volk]

Is that the one in front of the American Legion post in Donelson?

Yes, that's it.

 

[4v50 Gary]

Pward's got it right. The M36 utilized the chasis of the M10 which itself was based on the Sherman (but w/out the armor).

BTW, if you really want firepower, how about the Vespa motorscooter with the recoil-less rifle mounted on it? The ultimate for in/out drive bys.

Manufacturer Cadillac

MUCH more pimpin that an Escalade!

 

[280PLUS]

this thread kind reminds me of,,,

when i was in the nav they had a frigate which they had mounted an 8" gun on the bow of this otherwise lightweight ship

no matter what they did to reinforce the bow, every time they shot it off, the ship had to go in for repairs and get all the cracks welded up again,,,

wish i could remember the name of the boat,,,oh well
