John Philip Holland and Holland 1 red and black plaque in Gosport
Designer: John Philip Holland
Built by Vickers Maxim at Barrow-in-Furness and launched in 1901, this pioneer submarine was powered by a 160hp petrol engine and had a surface speed of 8 knots. A 70hp electric motor gave a submerged speed of 7 knots.
Holland 1 was the Royal Navy's first operational submarine.
John Philip Holland (Irish: Seán Pilib Ó hUallacháin / Ó Maolchalann) (29 February 1840 – 12 August 1914) was an Irish engineer who developed the first submarine to be formally commissioned by the U.S. Navy, and the first Royal Navy submarine, the Holland 1. He is widely regarded as the father of the modern submarine for his designs.
Holland 1 (or HM submarine Torpedo Boat No 1) was the first submarine commissioned by the Royal Navy, the first in a six-boat batch of the Holland-class submarine. She was lost in 1913 while under tow to the scrapyard following decommissioning. Recovered in 1982, she was put on display at the Royal Navy Submarine Museum, Gosport.
