USS Jacksonville
USS ''Jacksonville'' (SSN-699), a nuclear powered attack submarine, is the only vessel of the United States Navy to be named for Jacksonville, Florida. ''Jacksonville'' was overhauled and modernized in 1988 and over the career span was involved in four collisions between 1982 and 2013. After completing a final deployment in 2017, ending 36 years of active service, the submarine was decommissioned in 2021. History The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on 24 January 1972 and her keel was laid down on 21 February 1976. She was launched on 18 November 1978 using the pontoon system designed for the launching of the Trident submarines. ''Jacksonville'' was sponsored by Mrs. Dorothy Jean Bennett, wife of Congressman Charles E. Bennett, and commissioned on 16 May 1981. ''Jacksonville''s operations have included a variety of fleet exercises and deployments including two around-the-world cruises i ...

Jacksonville, Florida
Jacksonville is a city located on the Atlantic coast of northeast Florida, the most populous city proper in the state and is the largest city by area in the contiguous United States as of 2020. It is the seat of Duval County, with which the city government consolidated in 1968. Consolidation gave Jacksonville its great size and placed most of its metropolitan population within the city limits. As of 2020, Jacksonville's population is 949,611, making it the 12th most populous city in the U.S., the most populous city in the Southeast, and the most populous city in the South outside of the state of Texas. With a population of 1,733,937, the Jacksonville metropolitan area ranks as Florida's fourth-largest metropolitan region. Jacksonville straddles the St. Johns River in the First Coast region of northeastern Florida, about south of the Georgia state line ( to the urban core/downtown) and north of Miami. The Jacksonville Beaches communities are along the adjacent Atlantic ...

Fairwater Plane
Diving planes, also known as hydroplanes, are control surfaces found on a submarine which allow the vessel to pitch its bow and stern up or down to assist in the process of submerging or surfacing the boat, as well as controlling depth when submerged. Bow and stern planes Diving planes are usually fitted in two pairs, the '' bow planes'' at the front of the submarine and the ''stern planes'' at the rear. The stern planes function in much the same way as an aircraft's elevator. As the planes are a long distance fore-and-aft from the hull's centre of buoyancy, they introduce a pitching moment. Ballast tanks within the submarine adjust buoyancy to be neutral, making the boat controllable. The position of the planes controls the pitch of the boat and, with the forward motion of the boat, this controls depth. If not carefully controlled, this could lead to a 'porpoising' motion whereby the planesman continually hunts for a stable combination of depth and pitch. For easier berth ...

Ships Built In Groton, Connecticut
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were con ...

Naval Vessel Register
The ''Naval Vessel Register'' (NVR) is the official inventory of ships and service craft in custody of or titled by the United States Navy. It contains information on ships and service craft that make up the official inventory of the Navy from the time a vessel is authorized through its life cycle and disposal. It also includes ships that have been removed from the register (often termed '' stricken'' or ''struck''), but not disposed of by sale, transfer to another government, or other means. Ships and service craft disposed of prior to 1987 are currently not included, but are gradually being added along with other updates. History The NVR traces its origin back to the 1880s, having evolved from several previous publications. In 1911, the Bureau of Construction and Repair published ''Ships Data US Naval Vessels'', which subsequently became the ''Ships Data Book'' in 1952 under the Bureau of Ships. The Bureau of Ordnance's ''Vessel Register'', first published in 1942 and retitl ...

MK 48
The Mark 48 and its improved Advanced Capability (ADCAP) variant are American heavyweight submarine-launched torpedoes. They were designed to sink deep-diving nuclear-powered submarines and high-performance surface ships. History The Mark 48 was initially developed as REsearch TORpedo Concept II (RETORC II), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. The Mk-48 torpedo was designed at the end of the 1960s to keep up with the advances in Soviet submarine technology. Operational since 1972, it replaced the Mk-37, Mk-14 and Mk-16 torpedoes as the principal weapon of U.S. Navy submarines. With the entry into service of the new Soviet in 1977, the decision was made to accelerate the ADCAP program, which would bring significant modifications to the torpedo. Tests were run to ensure that the weapon could keep up with the developments and the weapon was modified with improved acoustics and electronics. The new ...

Smoke Inhalation
Smoke inhalation is the breathing in of harmful fumes (produced as by-products of combusting substances) through the respiratory tract. This can cause smoke inhalation injury (subtype of acute inhalation injury) which is damage to the respiratory tract caused by chemical and/or heat exposure as well as possible systemic toxicity after smoke inhalation. Smoke inhalation can occur from fires of various sources such as residential, vehicle, and wildfires. Morbidity and mortality rates in fire victims with burns are increased in those with smoke inhalation injury. Victims of smoke inhalation injury can present with cough, difficulty breathing, low oxygen saturation, smoke debris and/or burns on the face. Smoke inhalation injury can affect the upper respiratory tract (above the larynx), usually due to heat exposure, or the lower respiratory tract (below the larynx), usually due to exposure to toxic fumes. Initial treatment includes taking the victim away from the fire and smoke, give 1 ...

Refueling Overhaul
In the United States Navy, Refueling and Overhaul (ROH) refers to a lengthy refitting process or procedure performed on nuclear-powered naval ships, which involves replacement of expended nuclear fuel with new fuel and a general maintenance fix-up, renovation, and often modernization of the entire ship. In theory, such a process could simply involve only refueling or only an overhaul, but in practice, nuclear refueling is always combined with an overhaul. An ROH usually takes one to two years for submarines and up to almost three years for an aircraft carrier, performed at a naval shipyard. Time periods between ROHs on a ship have varied historically from about 5–20 years (for submarines) to up to 25 years (for s). For modern submarines and aircraft carriers, ROHs are typically carried out about midway through their operating lifespan. There are also shorter maintenance fix-ups called ''availabilities'' for ships periodically at shipyards. A particularly lengthy refueling, ...
