USS Mount Whitney (LCC-20)
USS ''Mount Whitney'' (LCC/JCC 20) is one of two amphibious command ships of the United States Navy and is the flagship and command ship of the United States Sixth Fleet. USS ''Mount Whitney'' also serves as the Afloat Command Platform (ACP) of Naval Striking and Support Forces NATO (STRIKFORNATO). The ship had previously served for years as the COMSTRIKFLTLANT(NATO Designation) / US Second Fleet's command ship. She is one of only a few commissioned ships to be assigned to Military Sealift Command. ''Mount Whitney'' was classified as LCC-20 on 1 January 1969, and her keel was laid down on 8 January by Newport News Shipbuilding & Drydock Company, Newport News, Virginia. At the time of her commissioning, ''Mount Whitney'' joined her sister ship ''Blue Ridge'' as having the distinction of carrying the world's most sophisticated electronics suites. It was said to be some thirty percent larger than that of the aircraft carrier USS ''John F. Kennedy'', which had been the most ...

Mount Whitney
Mount Whitney (Paiute: Tumanguya; ''Too-man-i-goo-yah'') is the highest mountain in the contiguous United States and the Sierra Nevada, with an elevation of . It is in East–Central California, on the boundary between California's Inyo and Tulare counties, west-northwest of North America's lowest point, Badwater Basin in Death Valley National Park, at below sea level. The mountain's west slope is in Sequoia National Park and the summit is the southern terminus of the John Muir Trail, which runs from Happy Isles in Yosemite Valley. The eastern slopes are in Inyo National Forest in Inyo County. Geography Mount Whitney's summit is on the Sierra Crest and the Great Basin Divide. It lies near many of the Sierra Nevada's highest peaks. The peak rises dramatically above the Owens Valley, sitting or just over above the town of Lone Pine to the east, in the Owens Valley. It rises more gradually on the west side, lying only about above the John Muir Trail at Guitar Lake. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Second Fleet
The United States Second Fleet is a numbered fleet in the United States Navy responsible for the East Coast and North Atlantic Ocean. The Fleet was established following World War II. In September 2011, Second Fleet was deactivated in view of the United States Government's perception that the potential military threat posed by Russia had diminished. On 4 May 2018, Admiral John M. Richardson, the Chief of Naval Operations, announced plans to reestablish Second Fleet amid heightened tensions between NATO and Russia. It was reestablished on 24 August 2018, with Vice Admiral Andrew "Woody" Lewis in command. Second Fleet's historic area of responsibility included approximately of the Atlantic Ocean from the North Pole to the Caribbean and from the shores of the United States to the middle of the Atlantic Ocean. Second Fleet's United States West Coast counterpart was United States First Fleet from the immediate post-World War II years until 1973, and United States Third Fleet from ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C4ISTAR
Command and control (abbr. C2) is a "set of organizational and technical attributes and processes ... hatemploys human, physical, and information resources to solve problems and accomplish missions" to achieve the goals of an organization or enterprise, according to a 2015 definition by military scientists Marius Vassiliou, David S. Alberts, and Jonathan R. Agre. The term often refers to a military system. Versions of the United States Army ''Field Manual 3-0'' circulated circa 1999 define C2 in a military organization as the exercise of authority and direction by a properly designated commanding officer over assigned and attached forces in the accomplishment of a mission. A 1988 NATO definition is that command and control is the exercise of authority and direction by a properly designated individual over assigned resources in the accomplishment of a common goal. An Australian Defence Force definition, similar to that of NATO, emphasises that C2 is the system empowering des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sierra Nevada
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils Po ...

High Frequency
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters). Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band. The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio. Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere – a method known as "skip" or " skywave" propagation – these frequencies are suitable for long-distance communication across intercontinental distances and for mountainous terrains which prevent line-of-sight communications. The band is used by international shortwave broadcasting stations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not successfully landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
