This shipyard is where the United States Navy's first submarines were built under Busch's supervision beginning in the late fall of 1896. Busch worked in unison with John Philip Holland to design and build the pioneering , also known as the "Holland VI" design. This was the first commissioned submarine in the United States Navy, and purchased by the American Government on April 11, 1900 – a day later commemorated by the United States submarine community as "Submarine Day".
