At random: Interests in submarines extends to royalty and presidents. The King of England and the King and Queen of Spain are among those who have made submerged cruises in submarines. As a result of a trip in an early United States submarine, President "Teddy" Roosevelt ordered extra compensation for personnel serving in the "Silent Service." President Harry Truman made a 440 foot dive in a captured German submarine. The first President to cruise aboard a nuclear submarine was President Eisenhower who rode the USS SEAWOLF out of Newport, Rhode Island on September 26, 1957.

Subject: Sub invisibility

I have been reading a lot of research about stealth on the boats. The latest possibility seems to entail development of new metallic wrappings (not coating) which can be made to capture incoming noise (active sonar) and channel it through hollow, aluminum/alloy spaces within the wrap and away from the source of the incoming noise. Other possibilities use Buckyballs, a form of carbon which is hollow also. In a way it is similar to using temperature gradients to deflect active sonar. It won't be far into the future when these materials and composite/ceramic will be used to build stronger hulls. The biggest obstacle to the wraps is weight. Composites are coming but are currently unreliable for use in environments which vary the pressures to which they are subjected. A deep dive requires the composite' resistance to pressure which steel hulls can adapt to. Ceramics are brittle, especially at low temperatures. Perhaps some future "alloying" of ceramics, composites and steels are the answer? Comments?
