Holland's advanced ideas on armament, hull form, and electric underwater propulsion were embodied in his Holland VI, the first modern submarine, constructed at Elizabethport, New Jersey, in 1897 and commissioned by the U.S. Navy as SS‐1 in 1900. Holland's Electric Boat Company secured navy contracts for five additional submersibles, followed by orders from Great Britain, Russia, and Japan. Simon Lake, Holland's principal design rival, entered mounting international competition with contracts for Russia, Austria, Germany, and in 1911 with the United States. Shuffled aside by Electric Boat management, Holland, father of the American and the British submarine, devoted his final years to aeronautical research.
