A Submarine That Can Go 100 Knots. The fastest submarine in the US Navy can go only 25 to 30 knots. But the Electric Boat Corporation, the primary designer for US Navy submarines, is trying to design one that can reach up to 100 knots. It plans on testing a 1/4 scale model off the coast of Rhode Island next year:
Believe it or not, tanks can actually move at about 25 miles per hour on flat terrain and up to 45 miles per hour on roads! Some tanks have even gone as fast as 60 to 70 miles per hour for short periods of time.Tanks aren't really built for speed, though.Driving tanks at high speeds often leads to mechanical problems and breakdowns. Tanks perform better at slow speeds over short distances.ome tanks have even gone as fast as 60 to 70 miles per hour for short periods of time. Tanks aren't really built for speed, though.
