DSV-5 Nemo
DSV-5, ex-NEMO (Naval Experimental Manned Observatory), was a submersible used by the United States Navy between 1970 and 1986 to oversee and observe undersea construction work. NEMO had a spherical transparent acrylic hull, which gave occupants panoramic vision. NEMO was the first submersible with a hull made entirely out of transparent acrylic (Plexiglass), and much of her career was spent testing this hull design. NEMO was found to be an effective observation platform, despite not being able to hover in place, and acrylic-hulled submersibles have continued to be built and operated in the United States. NEMO is considered part of the ''Alvin'' class of Deep Submergence Vehicles despite bearing little resemblance to the other subs of the class. NEMO was transferred to "other government agencies" (likely the CIA) in 1986 and retired from government service in 2011. It was then given to the U.S. Navy Seabee Museum, where it remains on display. Design NEMO consisted of a spherical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Facilities Engineering Command
The Naval Facilities Engineering Systems Command (NAVFAC) is the United States Navy's engineering systems command, providing the Navy and United States Marine Corps with facilities and expeditionary expertise. NAVFAC is headquartered at the Washington Navy Yard and is under the command of the Chief of Civil Engineers RADMbr>Dean VanderLey The Naval Facilities Engineering Systems Command is the oldest of the Navy's system commands, having been established as the Bureau of Yards and Docks in August 1842. Its officers comprise the Navy Civil Engineer Corps, which was formed in March 1867. During the 1966 reorganization of the Department of the Navy, the Bureau of Yards and Docks became the Naval Facilities Engineering Command. In October 2020, the name changed to the current Naval Facilities Engineering Systems Command.

Midget Submarines
A midget submarine (also called a mini submarine) is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships. Most early submarines would now be considered midget submarines, such as the United States Navy's and the British Royal Navy's (both named for the same designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-craft and the unsuccessful Welman submarine, were specifically designed with t ...

Naval Base Ventura County
Naval Base Ventura County (NBVC) is a United States Navy base in Ventura County, California. Formed by the merger of NAS Point Mugu and CBC Port Hueneme, NBVC is a diverse installation composed of three main locations — Point Mugu, Port Hueneme, and San Nicolas Island. The base serves as an all-in-one mobilization site, deep water port, railhead, and airfield. NBVC supports more than 100 tenant commands with a base population of more than 19,000 personnel, making it the largest employer in Ventura County. History Naval Construction Battalion Center Port Hueneme The facility at Port Hueneme was built as a temporary depot in the early days of World War II to train, stage, and supply the newly created Seabees (from "C.B.", the initials for "Construction Battalion"). The base was officially established and began operating May 18, 1942 as the Advance Base Depot. In 1945 the Advance Base Depot was renamed the Naval Construction Battalion Center.

Channel Islands
The Channel Islands ( nrf, Îles d'la Manche; french: îles Anglo-Normandes or ''îles de la Manche'') are an archipelago in the English Channel, off the French coast of Normandy. They include two Crown Dependencies: the Bailiwick of Jersey, which is the largest of the islands; and the Bailiwick of Guernsey, consisting of Guernsey, Alderney, Sark, Herm and some smaller islands. They are considered the remnants of the Duchy of Normandy and, although they are not part of the United Kingdom, the UK is responsible for the defence and international relations of the islands. The Crown dependencies are not members of the Commonwealth of Nations, nor have they ever been in the European Union. They have a total population of about , and the bailiwicks' capitals, Saint Helier and Saint Peter Port, have populations of 33,500 and 18,207, respectively. "Channel Islands" is a geographical term, not a political unit. The two bailiwicks have been administered separately since the late ...

Shirt-sleeve Environment
"Shirt-sleeve environment" is a term used in aircraft design to describe the interior of an aircraft in which no special clothing need be worn. Early aircraft had no internal pressurization, so the crews of those that reached the stratosphere had to be garbed to withstand the low temperature and pressure of the air outside. Respirator masks needed to cover the mouth and nose. Silk socks were worn to retain heat. Sometimes leather clothing, such as boots, were electrically heated. When jet fighter aircraft reached still higher altitudes, something similar to a space suit had to be worn, and pilots of the highest reconnaissance aircraft wore real space suits. Commercial jet airliners fly in the stratosphere, but because they are pressurized, they could be said to have a shirt-sleeve environment. Crews of the US Apollo spacecraft always began the flight phases of launch, docking, and re-entry in space suits, although they could remove them for many hours. The Soviets tried t ...

Seabees
United States Naval Construction Battalions, better known as the Navy Seabees, form the U.S. Naval Construction Force (NCF). The Seabee nickname is a heterograph of the initial letters "CB" from the words "Construction Battalion". Depending upon context, "Seabee" can refer to all enlisted personnel in the USN's occupational field 7 (OF-7), all personnel in the Naval Construction Force (NCF), or Construction Battalion. Seabees serve both in and outside the NCF. During World War II they were plankowner, plank-holders of both the Naval Combat Demolition Units and the Underwater Demolition Teams (UDTs). The men in the NCF considered these units to be "Seabee". In addition, Seabees served as elements of Cubs, Lions, Acorns and the United States Marine Corps. They also provided the manpower for the top secret CWS Chemical Warfare Service: Flame Tank Group Seabees, Flame Tank Group. Today the Seabees have many special task assignments starting with Camp David and the Naval Support Unit at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crush Depth
Depth ratings are primary design parameters and measures of a submarine's ability to operate underwater. The depths to which submarines can dive are limited by the strengths of their submarine hull, hulls. Ratings The hull of a submarine must be able to withstand the forces created by the outside water pressure being greater than the inside air pressure. The outside water pressure increases with depth and so the stresses on the hull also increase with depth. Each 10 metres (33 feet) of depth puts another atmosphere (1 bar, 14.7 psi, 101 kPa) of pressure on the hull, so at 300 metres (1,000 feet), the hull is withstanding thirty atmospheres (30 bar, 441 psi, 3,000 kPa) of water pressure. Test depth The maximum depth at which a submarine is permitted to operate under normal peacetime circumstances, and is tested during sea trials. The test depth is set at two-thirds (0.66) of the design depth for United States Navy submarines, while the Royal Navy sets test depth at 4/7 (0.57) t ...
