Are subs faster underwater?
Yes, as Larry has succinctly pointed out with a neat cross reference, the modern submarine travels faster underwater than on the surface. … Since the pre-nuclear subs would therefore be spending most of their time on the surface of the sea, it made sense to give them a shipshape, seaworthy hull form for best speed.
Why are subs faster underwater?
Frictional and pressure resistance happens for submarines and surface ships. Frictional resistance happens as the water slide past the hull. … So, since submarines for the same speed see less resistance, only frictional and pressure and not wave. So sumarines, for the same power, can go faster underwater.
