Next-Generation Bomber
The Next-Generation Bomber (NGB; unofficially called 2018 Bomber) was a program to develop a new medium bomber for the United States Air Force. The NGB was initially projected to enter service around 2018 as a stealthy, subsonic, medium-range, medium payload bomber to supplement and possibly—to a limited degree—replace the U.S. Air Force's aging bomber fleet (B-52 Stratofortress and B-1 Lancer). The NGB program was superseded by the Long Range Strike Bomber (LRS-B) heavy bomber program. Development 1999 Air Force White Paper on Long Range Bombers controversy In 1999, the Air Force released a white paper stating that it would need a new "capability" around 2037 to replace retiring bombers. The paper estimated that due to mishap attrition and other factors other than useful service life, the number of B-1 Lancer would not meet Air Force requirements of 89 aircraft by 2018. For the B-2, the number of aircraft would slip below the service's requirements of 19 aircraft by 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Power Projection
Power projection (or force projection or strength projection), in international relations, is the capacity of a state to deploy and sustain forces outside its territory. The ability of a state to project its power into an area may serve as an effective diplomatic lever, influencing the decision-making process and acting as a potential deterrent on other states' behavior.Pravda (Правда(17 Mar 2022) Zelenskyy explained the essence of the new military alliance U24 from Zelenskyy's night address verbatim: "I addressed the United States and all responsible states with a proposition to create a new U24 union: a new union that will ensure that each aggressor receives a coordinated world response quickly, effectively, and immediately - not in weeks, months, years, but for the first 24 hours after the attack." "We can no longer trust existing institutions. We cannot expect bureaucrats in international organisations to change fast enough, so we must look for new guara ...

B-52
The Boeing B-52 Stratofortress is an American long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s. The bomber is capable of carrying up to 70,000 pounds (32,000 kg) of weapons,"Fact Sheet: B-52 Superfortress."

Penetrator (aircraft)
A penetrator is a long-range bomber aircraft designed to intrude against and penetrate enemy defenses. The term is mostly applied to aircraft that fly at low altitude to avoid radar, a strategic counterpart to the shorter-ranged tactical interdictor designs like the TSR-2 and F-111. The term can be applied to any aircraft that is designed to survive over enemy airspace, and has been used for the penetration fighter designs intended to escort bombers. The classic penetrator design is the Rockwell B-1 Lancer, where the term was first widely used. The larger Tupolev Tu-160 is also a member of this class. Other aircraft, like the Boeing B-52 Stratofortress and some versions of the F-111 have also been adapted to this role. More modern designs, like the Northrop Grumman B-2 Spirit, can be technically classified as penetrators, but the term is not generally applied to these aircraft.

Hypersonic
In aerodynamics, a hypersonic speed is one that exceeds 5 times the speed of sound, often stated as starting at speeds of Mach 5 and above. The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at different speeds; these effects collectively become important around Mach 5-10. The hypersonic regime can also be alternatively defined as speeds where specific heat capacity changes with the temperature of the flow as kinetic energy of the moving object is converted into heat. Characteristics of flow While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow. The peculiarity in hypersonic flows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USS Schenectady (LST-1185)
USS ''Schenectady'' (LST-1185) was the fifth which replaced the traditional bow door-design tank landing ships (LSTs). It was delivered to the US Navy on 1 May 1970 and commissioned on 13 June 1970. ''Schenectady'' operated in support of American forces in Vietnam and Operations Desert Shield and Desert Storm. It was decommissioned on 15 December 1993 and held in reserve until it was sunk as a target on 23 November 2004. Design and description ''Schenectady'' was a which were designed to meet the goal put forward by the United States amphibious forces to have a tank landing ship (LST) capable of over . However, the traditional bow door form for LSTs would not be capable. Therefore, the designers of the ''Newport'' class came up with a design of a traditional ship hull with a aluminum ramp slung over the bow supported by two derrick arms. The ramp was capable of sustaining loads up to . This made the ''Newport'' class the first to depart from the standard LST design that ...

Hypersonic Flight
Hypersonic flight is flight through the atmosphere below altitudes of about 90 km at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds of Mach 25+ have been achieved below the thermosphere as of 2020. History The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of , or about Mach 6.7. The vehicle, however, burned on atmospheric re-entry, and only charred remnants were found. In April 1961, Russian Major Yuri Gagarin became the first human to travel at hypersonic speed, during the world's first piloted orbital flight. Soon after, in May 1961, Alan Shepard became the first American and second person to fly hypersonic when his capsule reentered the atmosphere at a speed above Mach 5 at the end of his suborbital flight over the ...

Air Staff (United States)
The Air Staff is one of the Department of the Air Force's two statutorily designated headquarters staffs: the other staff is the '' Office of the Secretary of the Air Force'', also known as the ''Secretariat''. The Air Staff is headed by the Chief of Staff of the Air Force (currently General Charles Q. Brown Jr.). The Air Staff is primarily composed of uniformed U.S. Air Force officials who assist the Chief of Staff in carrying out his dual-hatted role: as the principal military advisor to the Secretary of the Air Force, and as a member of the ''Joint Chiefs of Staff''. The Air Staff was reorganized in 2006 to be numbered in accordance with the Joint Staff system. For the most part, the Joint Staff numbering system applies to the air staff. The Air Force separated Analysis and Assessments from A8 to create a separate directorate, A9, then in 2008, followed up with the creation of a separate directorate, A10, for the Air Force's nuclear mission.

Jane's Defence Weekly
''Jane's Defence Weekly'' (abbreviated as ''JDW'') is a weekly magazine reporting on military and corporate affairs, edited by Peter Felstead. It is one of a number of military-related publications named after John F. T. Jane, an Englishman who first published '' Jane's All the World's Fighting Ships'' in 1898. It is a unit of Jane's Information Group, which was purchased by IHS in 2007. The magazine has a large circulation and is frequently cited in publications worldwide. History ''Jane's Defence Weekly'' was established in 1984 replacing the now-defunct ''Jane's Defence Review''. The latter was started in 1978 and was published on a monthly basis. Samuel Loring Morison In 1984, only months after the magazine was established, ''Jane's Defence Weekly'' gained worldwide attention after printing several images from an American spy satellite of the Nikolaiev 444 shipyard in the Black Sea, showing a Kiev-class aircraft carrier under construction.https://news.google.com/newspapers? ...

Edward C
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned. ...
