I worked on a pressure test facility at the Navel Postgraduate School in Monterey while employed by MBARI in the ‘90s. They had a shell from a 16 inch gun (USS Iowa type) It had ‘China Lake’ stenciled on the side. The pointy end had been replaced with a plug. Curt Collins ran Oceanography at NPS and was on the board at MBARI and said that if I refurbished the equipment, we could use it. We both won. The chamber was about 9 1/2” in dia and about 4 feet long. Got it up to around 4000 psi. The PhD candidates I mentored also got privileges on the golf course. The end.
Good evening sasquatch, great story thank you!
