[PSUBS-MAILIST] K-600

[Jon Wallace]

It was an engineer hired by the company that commissioned and purchased the 600.  His calculation requirements for the heads came out a little bit thicker than what George had calculated.  I believe George spec'd .5 inch and the company's engineer spec'd .5625 inch.

 George attributed the miscalculation in the weight
 of the 600 to second guessing the thickness of the heads.
 His original design called for thinner heads but
 someone (can't remember who) that George respected
 suggested that they should be thicker. George used the
 thicker heads and then found that the sub wouldn't
 float. He had the hull lengthened by Bath Iron Works to get
 the needed buoyancy back. He
 said he was amazed at how fast they turned the job around- I
 think it was only a few days.
