I think a member here might have been part of the crew, or at least nearby, when that happened? Safecracker, or the other safe guy?

IIRC, there were concerns here that the new guns wouldn't be worthy of old world standards.
I hope no one was seriously harmed.

There's a whole bunch of original cannons at the Washington Navy Yard just rotting away. They should use one of those, I bet they would still work fine.

Thought this happened last year. I remember Safecracker talking about something happening with one of the cannon.

Manufacturing defects. They should issue a cannon recall.
Sounds like primarily quality control issues (poor weld quality does not look like full penetration, sleeve not centered and too far back, poor casting) also some design issues (sleeve cast in place vs bored and bonded other manufacturers use). I just hope this incident does not put an end to cannon firings at Ft. McHenery and elsewhere.

The fractured section of the barrel looks crystalline, like the steel was cast and chilled too quickly. This produces a brittle iron called Martensite, which is not what you want in a cannon.

They also admitted to overcharging, based on the "new'' arty manual. Would have thought they worked out the loads a couple centuries ago.
How did they drill the bores on these things 400 years ago?
