Austal USA
Austal USA is an American shipbuilder based on Blakeley Island in Mobile, Alabama. It is a subsidiary of the Australian shipbuilder Austal, operating under a Special Security Arrangement which allows it to work independently and separately on some of the most sensitive United States defense programs despite its foreign ownership.

Notable projects for the shipbuilder include the United States Navy's ''Independence'' class littoral combat ship (first launched in 2008) and United States Coast Guard's ''Heritage''-class cutter (contract awarded in 2022). Projects Austal USA's first contract was for two crew supply vessels for service in the Gulf of Mexico. These were followed by a ferry for Lighthouse Fast Ferry of New York. Austal USA built the ''Lake Express'' for service across Lake Michigan, and the ''A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SEAL Delivery Vehicle
The SEAL Delivery Vehicle (SDV) is a crewed submersible and a type of swimmer delivery vehicle used to deliver United States Navy SEALs and their equipment for special operations missions. It is also operated by the Royal Navy's Special Boat Service, which operates three SDVs. The SDV, which has been in continuous service since 1983, is used primarily for covert or clandestine missions to denied access areas (either held by hostile forces or where military activity would draw notice and objection). It is generally deployed from the Dry Deck Shelter on a specially-modified attack or ballistic missile submarines, although it can also be launched from surface ships or land. It has seen combat in the Gulf War, Iraq War, and the US intervention in Somalia. The SDV was intended to be replaced with the Advanced SEAL Delivery System (ASDS), a larger, dry submersible that is often confused with the SDV. The SDV is flooded, and the swimmers ride exposed to the water, breathing from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HSV-2 Swift
HSV-2 ''Swift'' is a hybrid catamaran. She was privately owned and operated by Sealift Inc., and was originally built under the JHSV program as a proof of concept. As part of this program, she was directly leased for evaluation from her builders by the United States Navy Military Sealift Command from 2003 to 2013, primarily as a mine countermeasures and sea basing test platform. Later during her official naval career she was mostly used for fleet support and humanitarian partnership missions. In July 2015, the ship was leased by the United Arab Emirates National Marine Dredging Company and was used to carry aid through the Bab Al Mandab strait.

USNS Choctaw County Awaits Delivery
United States Naval Ship (USNS) is the prefix designation given to non- commissioned ships that are property of the United States Navy (USN). Definition United States Naval Ships are unarmed auxiliary support vessels owned by the U.S. Navy and operated in non-commissioned service by Military Sealift Command with a civilian crew. Some ships include a small military complement to carry out communication and special mission functions, or for force protection. In comparison, U.S. Navy ships commissioned into service have the designation " USS" and are armed, crewed by U.S. Navy personnel, and held in property by the United States Government. Additionally, the United States Naval Ships hull classification symbol begins with "T-" to denote its civilian crew. The USNS prefix can be assigned only while the ship is owned by the U.S. Navy. If, after being taken out of service, the ship is transferred to the Maritime Administration the prefix reverts to a civilian ship prefix such as ...

Seasickness
Motion sickness occurs due to a difference between actual and expected motion. Symptoms commonly include nausea, vomiting, cold sweat, headache, dizziness, tiredness, loss of appetite, and increased salivation. Complications may rarely include dehydration, electrolyte problems, or a lower esophageal tear. The cause of motion sickness is either real or perceived motion. This may include from car travel, air travel, sea travel, space travel, or reality simulation. Risk factors include pregnancy, migraines, and Ménière's disease. The diagnosis is based on symptoms. Treatment may include behavioral measures or medications. Behavioral measures include keeping the head still and focusing on the horizon. Three types of medications are useful: antimuscarinics such as scopolamine, H1 antihistamines such as dimenhydrinate, and amphetamines such as dexamphetamine. Side effects, however, may limit the use of medications. A number of medications used for nausea such as ondansetron are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Racking
Hot racking (also known as hot bunking or hot bedding) is the sanctioned practice within military organizations of assigning more than one crew member to a bed or "rack" to reduce berthing (sleeping) space. History The practice dates back at least to the sixteenth century, and today is particularly applied aboard submarines, where maximization of space is especially important. Generally, the lowest ranking members of the crew are required to hot rack. Hot racking is sometimes utilized in jails and prisons to deal with overcrowding. Depending upon the watch system, two, or even three people may end up sharing the same bunk. The term comes from the military slang use of the term "rack" for a bed or bunk. With more than one crew member assigned to a rack, it is possible that a crew member returning from a duty shift will lie down on a rack immediately after it is vacated by another crew member about to start a shift. The rack is therefore said to be "hot", that is, still warm from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
