M65 Atomic Cannon ("Atomic Annie")
US Army Gun, Heavy, Motorized, 280mm, M65 Atomic Annie | 12 August 2012 | Tankograd Technical Manual Series N 6001

Posted on 08/12/2012 3:45:46 PM PDT by moonshot925

20 cannons were manufactured from 1951 to 1953.

The cannon fired a W9 or W19 nuclear artillery shell with a maximum range of 24-29 miles.

5 Field Artillery Battalions were deployed to the 7th Army in West Germany between October 1953 and April 1954. The units were hosted by the 42nd Field Artillery Group.

Each battalion had 3 280mm guns, 30 officers, 7 warrant officers and 401 enlisted men.

All of the cannons were retired in December 1963.

It is my understanding that the Marines also had these weapons. They went over the side about two weeks after a landing as I recall.

I remember reading about those when I was a kid and they were still deployed. Pretty cool, but not terribly practical as a theater weapon. To big and stationary . . . even in the 50's.

Thanks for the memories.

It would fill up my back yard such as it is nicely and I would have the barrel end pointing at the militant marxist’s house next door.

The ground around here is rather soft so I would expect it to sink in a 1/4 of its base or more.

Annie should always be remembered for helping to end a war and save lives-without firing a shot in anger.

Awesome!

That’s very interesting. I’d never knew we had nuclear artillery units. I bet those were pretty risky for the guys on the ground, depending on which way the wind is blowing and all.

It never ceases to amaze me in how the Iranians(among others) are still trying to catch up to where we were 60-70 years ago in the ‘nuclear age’ of warfare.

It was an awesome cannon, but the fact it was extremely unwieldy to move around was the reason why as soon as the we got nuclear artillery that could be fired from 155 mm howitzers these were quickly retired. This probably why they eventually replaced this cannon (plus other short range ballistic missiles) with the much more capable MGM-52 Lance missile, which was air tranportable with the C-5 Galaxy.

Not to my knowledge. There was the 663rd Field Artillery Battalion deployed to Okinawa from 1955 to 1957. But this was Army not Marines.

The Marines had other kinds of nuclear like W33 and W48 shells fired from M110 and M114 howitzers.

In many pics of Atomic explosions, what are those white streaks you often see near the ‘Mushroom Cloud’ that appear to be going up and down from the ground to the sky? (anyone know?)

They almost appear to be from a secondary explosion of some sort from within the bomb itself.

You most certainly wouldn't want to fire short.

Unit I was in had Davey Crockett rockets ~ they were being phased out at the time. I think that was the only atomic weaponry ever issued to the Infantry.

marines never had them. based on information gained from examining the 2 german 28cm K-5 railroad guns captured after the anzio breakout (finally). both were brought to the states and used to fix one to test fire. K-5 LEOPOLD used to sit across the street from the atomic cannon at APG

You should have seen our nuclear 40mm rounds fired from an M79 or M203. Each shot was "danger close." Glad we never had to use them.

Yes. Those are instrument-carrying rockets intended to measure various aspects of a test explosion. What you're seeing are the rocket trails, going from the ground up.

The yield of the bomb can be estimated from the horizontal distortion of the vertical stream made by smoke rockets. The rockets were launched just prior to the explosion.

“In many pics of Atomic explosions, what are those white streaks you often see near the ‘Mushroom Cloud’ that appear to be going up and down from the ground to the sky? (anyone know?)”

Those were made by small rockets fired off instants before the bomb went off to generate smoke trails so as to give a visual indication of the propagation of the shock wave.

Actually, i read somewhere it was otherwise, they were created by some static electric discharge or something created by the blast initial effect, not effected by the shock wave or to measure the shockwave

I saw some show that talked about this gun. Since it was unwieldy, taking a day to set up, and with only a handful of them around, the Soviets constantly had them targeted.

They are rockets that are launched just before the test.

They are spaced apart so that they become distance markers.

They are used for making measurements of the yield.

M65 Atomic Cannon ("Atomic Annie")

After a few drinks with a Los Alamos newkyewler program manager, this atomic cannon came up in the conversation.

He couldn't stop laughing.

I never read that, but I can’t claim direct knowledge. Any kind of static electricity discharge or orderly fields set up by the blast I would imagine would be obliterated by the sheer flood of ions and particles of all sorts emitting from the blast. That’s why I think (and have read) that they are just dumb smoke trails from rockets launched immediately pre-detonation. And, as you say, they are only visible on *some* of those early Nevada (NM, in the case of Trinity) blasts, which were all photographed in roughly the same fashion.

I used to wonder for years about the smoke trails, then read that they were to get a reading on shock waves. There are actually two shock waves of interest to weaponeers figuring out optimum burst height, an air wave and ground wave. These join up and interesting things happen. The smoke gives them an idea what is going on.

There was also the W-23 naval nuclear artillery shell, deliverable from the 16 inch guns of an Iowa-class battleship.

At 15-20 kt, it would have made a hell of a shore bombardment.

They are smoke rockets fired near the blast site to allow accurate scaling to be derived from photos.

As many have answered here, they are markers to help gauge the yield.

More significantly, back in those days, say early 50s, guys like Feshbach and Morse out of MIT were considered experts in “Acoustics”. Acoustics was the 50’s buzzword for studying atmospheric phenomenon associated with atomic/nuclear blasts. While much could be calculated, the clouds and trails provided hard evidence of how the detonations actually effected the physical domain.

Explosions tend to be many rates of reaction occuring in very short periods of time, with the products of one reaction also effecting subsequent reactions, with many having exponentially rapid rates of reaction.

While theoretical calculations indicated what blast yields might evolve, it wasn’t known if other rates of reaction of targeted areas wouldn’t exponentially further the initial detonation. Nor was it clearly known how the atmosphere at various elevations, temps and pressures might react to the event.

This became more prolific with thermonuclear tests. I had read some at the Bikini tests had posited the detonation could trigger a self sustaining reaction consuming all the planet’s oxygen, though not shown to be the case.

Yes. Development began in 1952 and the first W23 projectile was delivered in 1956. A total of 50 were produced. USS Iowa, USS New Jersey and USS Wisconsin had an alteration made to Turret II magazine to incorporate a secure storage area for these projectiles(USS Missouri was decommissioned in 1955 which is why she was not altered). This meant that an Iowa class battleship could fire several Hiroshima sized weapons to a range of up to 23 miles and have them hit target very accurately.

FTA: The units were hosted by the 42nd Field Artillery Group.

My LANCE battalion was part of that group when I was in West Germany, well after the time Atomic Annie had been sent to the Field Artillery Museum at Fort Sill OK. The article doesn't state but the cannon follow-ons for the group were the 8" howitzer and the 175mm gun. The rocket/missile units were Honest John and Sergeant. My battalion converted from the Sergeant system about 5 years before I got there.
