U. S. submarines in World War II had a top surface speed of around 20-knots. Submerged, their top speed was around 9-knots, although at that speed they would exhaust their batteries after one hour and have to surface to recharge them.
As of 2014, a submarine can travel between 49 and 52 miles per hour. The exact speed depends on the make of the sub and whether it is traveling on the surface or under water.

High Speed Diesel is a specific type of diesel fuel designed for high-speed diesel engines, typically used in automotive applications. Diesel fuel, on the other hand, is a more general term that refers to any fuel used in diesel engines, which can include High Speed Diesel as well as other diesel blends for various applications.
Diesel-electric submarine batteries have become pretty sophisticated and efficient - during WWII, only a couple of days or less between battery charges was the norm. Today, DE boats can go well over 20 days or more between charges, assuming there's no significant battery loading (flank speed maneuvers, etc.)
