 Is the Navy is moving to HSLA 80 and 100 and 
should one expect that these are or will be included in the standards? Perhaps 
when I query suppliers/fabricators I will find that the price makes this a moot 
issue.  
Can anyone recommend software or speadsheet 
calculations for evaluating truncated cone sections? 
Is there an "X-Plane" for subs?
