John Philip Holland (Irish: Seán Pilib Ó hUallacháin/Ó Maolchalann [citation needed]; February 24, 1841 [1] – August 12, 1914 [2]) was an Irish marine engineer who developed the first submarine to be formally commissioned by the US Navy, and the first Royal Navy submarine, Holland 1.
The upcoming Columbia-class (formerly known as the Ohio Replacement Submarine and SSBN-X Future Follow-on Submarine) nuclear-powered ballistic missile submarines of the United States Navy are designed to replace the Ohio class. [7] Construction of the first vessel began on 1 October 2020. [8] She is scheduled to enter service in 2031. [9] [10] [11]
A submarine (or sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) [2] The term “submarine” is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub).
The two men worked together using many of John Holland's proven concepts and patents to make the submarine a reality, each man complementing the other's contributions to the development of the modern submarine. John Holland was the inventor for US Patent 702,729 for the design of a submarine boat.
Navies across the world have been working to make their compact submarines more suitable for the modern-day sailor. Cramped and heavily armed — see what life is like aboard a nuclear submarine ...
The Virginia-class submarine was the first US Navy warship with its development coordinated using such 3D visualization technology as CATIA, which comprises computer-aided engineering (CAE), computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management (PLM). Design problems for Electric Boat—and ...
From the innovations of John Holland in the early twentieth century to the German U-boat campaigns of the World Wars, and the nuclear-powered ICBM submarines of the Cold War, modern navies embraced the submarine, first, for missions of reconnaissance and commerce-raiding, but, increasingly, in offensive, attack roles. In the postwar era, the ...
