No competition. Why worry about quality when you customer has no place else to go to get their ships built? There is a single company building carriers. A single company building large surface combatants. Two companies building destroyers. Two companies building submarines. Twenty or thirty years ago there were quite a few more.
No competition.Gee. That explains it all.
No mention of altered 'test' results, fudged QC activities, acceptance of non-conforming materials that FAILED at incoming QC, no mention of inspectors being bought off, no mention of using materials with NO trace-ability back to a legitimate vendor, just the old hand-waving saw about 'no competition'.
Great. You have it all nailed down.
