Well, I think initial efforts in the military employment of ANYTHING generally end in failure. That's just how technology tends to work. Geez, I'm thinking back to the Hunley - it sank three times by the time it finally sank another ship. If you only looked at its employment, submarines would definitely look like the worst weapon ever. But look where subs are today!
