            and sure enough, we were standing on a rotating floor that
            was used to vertically mill the 16” cannon turrets for a
            battleship. We figured this would be a good team.


            Newport News had the ability to easily handle the weight
            and size of the  structure and had a  good  capability for

            automated welding methods. We had the experience with
            high  strength  materials,  space  propulsion  systems,  and
            advanced  welding  technology  for  the  Maraging  Steels.

            Our only concern was their welding methodology using
            “Submerged  Arc”  techniques,  where  the  molten  metal

            generated in the welding process was submerged under a
            “chemical flux” to prevent oxidation and contamination
            of the  weld.  Our  approach  was  to  contain  the  molten
            metal under a blanket of inert gas (like an argon/helium

            mixture) which we had developed and proven.


            Newport  News  was  pretty  adamant  about  using  their
            methodology, and we indicated we might consider it if
            they  generated  test  samples  that  we  could  evaluate  for

            strength, ductility, and toughness. Our final team member
            search was for a contractor that had the rocket engine and
            large booster experience.  We tied up with Thiokol for

            this portion of the  effort,  and  after  senior  management
