Yesterday we did the load test on keel attachment point test section for the sub. We loaded it to 2.4X the required load and even smacked repeatedly with a mallet under over load just to be sure. Nothing like a month long build for a 3 hour test…

We had changing the mass of the submarines keel weight. The hull came in underweight and we changed the size of the internal flooded area. This means the keel attachment exceeds the original design load. It calcs well within the range, but we need to be sure. So we built a new hull test section to test it.
