THE SHIP
ABOUT

The new USS Little Rock is one of the Navy’s newest warships. It was built in Marinette, Wisconsin and is a Littoral Combat Ship (LCS) that will operate in waters close to the shore. The vessel also has a helicopter pad, a ramp for small boats and can be used by small assault forces.

The original USS Little Rock began its service as a light cruiser when World War II was coming to an end in 1945. It was officially decommissioned in 1949 and recommissioned in 1960 as a guided missile cruiser, before being taken out of service in 1976 and brought to Buffalo.

The name of the original USS Little Rock and the new vessel both pay tribute to Arkansas’ state capital. In her role, the USS Little Rock will play an important role in the new fleet of warships that will carry out our nation’s future maritime strategy.

FROM THE GROUND UP
  • Over 100 miles of electrical and fiber optic cable.
  • 1,000 tons of aluminum, 2,000 tons of steel.
  • 4 waterjets, that together pump over 1,976,000 gallons of water per minute (the equivalent of draining an Olympic size swimming pool in 20 seconds) at full power
  • Two Rolls-Royce MT30 gas turbine engines producing a total of 96,000 horsepower.  A direct derivation of the Trent 800 engines that power a Boeing 777; provide more horsepower than:
    • 223 Chevrolet Corvettes
    • 457 Ford Mustangs
    • 580 Harley Davidson VRXSE Destroyer V-Rod Destroyer Drag Racing Motorcycles
  • Two 16-cylinder Fairbanks Morse propulsion diesel engines, each displacing 5,200 liters (317,952 cubic inches) for a combined 17,370 horsepower.  Derived from railroad locomotives, these engines together produce more power than 35 semi-trucks
  • LCS FREEDOM variant power-to-weight ratio: 38 horsepower per ton.  Compares to:
    • DDG 51 Class Destroyer: 11 horsepower per ton
    • CVN 68 Class Aircraft Carrier: approximately 3 horsepower per ton.
  • Unique maneuverability to:
    • accelerate from 0 to 40+ knots in under 2 minutes
    • decelerate from 40+ to 0 knots in about 3 ship lengths
    • move directly sideways at 1 knot
    • rotate 360° while standing still in 3 minutes
