Since the destroyer was the only surface fleet unit that could effectively locate, attack and destroy a submarine, it was logical that we should develop a destroyer type that would concentrate on the submarine and thereby release destroyers for fleet assignment. Hence, the destroyer escort. By July of 1943, the program was going full blast. No less than sixteen U.S. yards were involved in building DEs. Between February 1943 and the end of the war in September 1945, 563 DEs were built.
Convert kilometers per hour to miles per hour. You are currently converting speed units from kilometers per hour to miles per hour. 1 kph = 0.62137119223733 mph. kilometers per hour.
Speed in meters per second (m/s) If something is traveling at 1 m/s it moves 1 meter every second. It is a gentle walking speed. One hour walking at 1 m/s moves you 3.6 km. Speed in kilometers per hour (km/h) If something is traveling at 1 km/h it moves 1 kilometer every hour. It is like a very slow walking speed. Kilometers per hour is often used for car speeds. Example: Highway speed is around 100 km/h. One hour at this speed moves you 100 km. Example: One minute at 60 km/h moves you 1 km.
