And are you in any of those pix?

Nope. Camera shy.

First person to correctly guess the caliber of that barrel wins.

155mm?

(I know they used to make them, not sure about now)

In reply to pinchvalve:

Do I win a slab of bacon?

"Booming" business. Very nice.

Here's a tip, 120s are smooth bores.

Caliber is not bore diameter. Caliber is the length of tube it takes to turn the shell one time, divided by the bore diameter.

Wouldn't happen to be the 155mm for the M777 would it?

Get your free bacon on the way out.

Our cannon are 105, 120 and 155mm. (in current production)

Russians are 107, 122 and 157mm. If they find some of our ammo around, they can use it.

Russians: "Our cannon are TWO louder"

In reply to 914Driver:

Woot! Wait, I don't see any free bacon......

I guess I'll stop at wendy's today for a baconator instead

My brother-in-law just came home from serving in Airborne artillery (which is a pretty entertaining mental picture). He's now deaf in one ear and I think he's got tinnitus. That's a job that leaves a little reminder for the rest of your life.

I shot high zone stuff with the Marines at 29 Palms. You cannot be "on line" for more than 10 rounds, it effects your hearing, you get chest pains and it effects your sleep.

HUGE Karboom! Puts the shell 22 miles away! I love night fire, the neighbors hate it.

Pat Travers song , " BOOM BOOM, out go the lights".

with the lack of dim. to compare it ... it looked like the 8" barrels that were on our heavy cruiser ... with would translate to (rounding error) 205mm howitzer

good on you yamaha .. hope the bacon is good

When I started here in 1978 we were making forty 8 inch guns a month for the Navy. We also put out the 175mm, longer barrel, same breech mech.

This is a 16 inch used on Battleships. When the rifling gets blown out, rather than build a whole new tube, we bore the center out and push in a sleeve. Then the sleeve is bored and rifled. Try making a slip fit part 30 feet long.

If you like this kind of stuff and find yourself near Aberdeen, Maryland; stop in at their museum. They have a football field covered with tanks and an indoor museum showing all kinds of weapons.
