^^ Pennsylvanian state Archive building, it's a beautiful monster.
I worked on a space probe in the 80s, we took two M-107 175mm gun tubes, turned one down to about 10 inches and screwed it onto the muzzle of the other. I saw it a few years ago laying on the outskirts of Yuma Proving Grounds looking forlorn.
BTW, Gerald Bull died after producing Project Babylon, a 3ft. diameter bored weapon for Saddam Hussein. No arrests made, but Israeli Mossad are suspected.

The best part of that pic is the little wake at the bow showing just how far to port she's been shoved by the recoil.

All factors considered that is incredibly, jaw droppingly, sit-you-back-in-your-seat dumb. It should be mostly below ground...
Judging the footprint dimensions by the scale of that egress door on the side facing us, most of it is below ground. Not to mention that a state as bureaucratic as Pennsylvania couldn't fit its archives into that volume if it was packed into solid reams, let alone filed in a way accessible to humans.

I've seen this thing around for years at various shows. Never seen it finished or close to running. Pretty much just a piece of art at this point.

Punkin Chunkin is no more. Poor organization and lack of insurance.

Great post, thanks. One thing made me curious. I thought that those uniforms looked like WWII, so I did a bit of searching. According to wikipedia, this is a Krupp K5 railway gun from WW II. The Paris guns of WW I were fixed in place.
From wiki: The Paris guns reached maximum altitude of 42.3 kilometers (26.3 mi)[1]:120—the greatest height reached by a human-made projectile until the first successful V-2 flight test in October 1942.
Really amazing. Here's the links, if anyone's interested.
My grandfather was wounded in the Argonne in 1918, so I've always had an interest in the history of The Great War. Again, thanks for posting the photo.

Aberdeen Proving Ground in MD has a Krup Rail Gun at their ordinance museum.
Had to screenshot, don't know how to link from faceplace. A local funeral home made prayer cards for the Flyers playoff loss.

I'm sure it had other issues, but the tires were the obvious weak spot.

Fmic kit that uses the factory ram air and shroud as the air intake. Always thought this was a neat (but complicated from a piping standpoint) setup
I almost bought one of them but there were never any proven gains released. Actually I think there was supposedly a bit of a loss from some community testing that was done.

The definition of rail gun has changed.
On the day the very last Air Force C-17 is retired, somewhere, a DC-3 will be making money hauling cargo.
