Bofors 40 mm gun
The Bofors 40 mm gun referred to as the Bofors gun, is an anti-aircraft autocannon designed in the 1930s by the Swedish arms manufacturer AB Bofors. It was one of the most popular medium-weight anti-aircraft systems during World War II, used by most of the western Allies as well some captured systems being used by the Axis powers. A small number of these weapons remain in service to this day, saw action as late as the Persian Gulf War. In the post-war era, the original design was not suitable for action against jet-powered aircraft, so Bofors introduced a new model of more power, the 40 mm L/70. In spite of sharing nothing with the original design other than the calibre and the distinctive conical flash hider, this weapon is widely known as "the Bofors". Although not as popular as the original L/60 model, the L/70 remains in service as a multi-purpose weapon for light armoured vehicles, as on the CV 90. Bofors has been part of BAE Systems AB since March 2005; the Swedish Navy purchased a number of 2-pounder Pom-Poms from Vickers as anti-aircraft guns in 1922.
The Navy approached Bofors about the development of a more capable replacement. Bofors signed a contract in late 1928. Bofors produced a gun, a smaller version of a 57 mm semi-automatic gun developed as an anti-torpedo boat weapon in the late 19th century by Finspång, their first test gun was a re-barreled Nordenfelt version of the Finspong gun, to, added a semi-automatic loading mechanism. Testing of this gun in 1929 demonstrated that a problem existed feeding the weapon in order to maintain a reasonable rate of fire. A mechanism, strong enough to handle the stresses of moving the large round was too heavy to move enough to fire rapidly. One attempt to solve this problem used zinc shell cases; this proved to leave heavy zinc deposits in the barrel, had to be abandoned. In the summer of 1930 experiments were made with a new test gun that did away with controlled feed and instead flicked the spent casing out the rear whereafter a second mechanism reloaded the gun by "throwing" a fresh round from the magazine into the open breech.
This seemed to be the solution they needed, improving firing rates to an acceptable level, the work on a prototype commenced soon after. During this period Krupp purchased a one-third share of Bofors. Krupp engineers started the process of updating the Bofors factories to use modern equipment and metallurgy, but the 40 mm project was kept secret; the prototype was completed and fired in November 1931, by the middle of the month it was firing strings of two and three rounds. Changes to the feed mechanism were all that remained, by the end of the year it was operating at 130 rounds per minute. Continued development was needed to turn it into a weapon suitable for production, completed in October 1933. Since acceptance trials had been passed the year before, this became known as the "40 mm akan M/32". Most forces referred to it as the "Bofors 40 mm L/60", although the barrel was 56.25 calibres in length, not the 60 calibres that the name implies. The gun fired a 900 g high explosive 40 × 311R shell at 2,960 ft/s.
The rate of fire was about 120 rounds per minute, which improved when the barrels were closer to the horizontal as gravity assisted the feeding from the top-mounted magazine. In practice firing rates were closer to 80–100 rpm, as the rounds were fed into the breech from four round clips which had to be replaced by hand; the maximum attainable ceiling was 7,200 m. The gun was provided with an advanced sighting system; the trainer and layer were both provided with reflector sights for aiming, while a third crew-member standing behind them "adjusted" for lead using a simple mechanical computer. Power for the sights was supplied from a 6V battery. In spite of the successful development, the Swedish Navy changed its mind and decided it needed a smaller hand-traversed weapon of 13 mm-25 mm size, tested various designs from foreign suppliers. With the 40 mm well along in development, Bofors offered a 25 mm version in 1932, selected as the Bofors 25 mm M/32; the first version of the 40 mm the Navy ordered was intended for use on submarines, where the larger calibre allowed the gun to be used for both AA and against smaller ships.
The barrel was shorter at 42 calibers long, with the effect of reducing the muzzle velocity to about 700 m/s. When not in use, the gun retracted into a watertight cylinder; the only known submarines that used this arrangement was the Sjölejonet-class boats. The guns were removed as the subs were modified with streamlined conning towers; the first order for the "real" L/60 was made by the Dutch Navy, who ordered five twin-gun mounts for the cruiser De Ruyter in August 1934. These guns were stabilized using the Hazemeyer mount, in which one set of layers aimed the gun, while a second manually stabilized the platform the gun sat on. All five mounts were operated by one fire control system. Bofors developed a towable carriage which they displayed in April 1935 at a show in Belgium; this mount allowed the gun to be fired from the carriage with no setup required, although with limited accuracy. If time was available for setup, the gunners used the tow-bar and muzzle lock as levers, raising the wheels off the ground and thereby lowering the gun onto supporting pads.
Two additional legs folded out to the sides, the platform was leveled with hand cranks. The entire setup process could be completed in under a minute. Orders for the land based versions were immediate, starting with
Seattle is a seaport city on the West Coast of the United States. It is the seat of Washington. With an estimated 730,000 residents as of 2018, Seattle is the largest city in both the state of Washington and the Pacific Northwest region of North America. According to U. S. Census data released in 2018, the Seattle metropolitan area’s population stands at 3.87 million, ranks as the 15th largest in the United States. In July 2013, it was the fastest-growing major city in the United States and remained in the Top 5 in May 2015 with an annual growth rate of 2.1%. In July 2016, Seattle was again the fastest-growing major U. S. city, with a 3.1% annual growth rate. Seattle is the northernmost large city in the United States; the city is situated on an isthmus between Puget Sound and Lake Washington, about 100 miles south of the Canada–United States border. A major gateway for trade with Asia, Seattle is the fourth-largest port in North America in terms of container handling as of 2015; the Seattle area was inhabited by Native Americans for at least 4,000 years before the first permanent European settlers.
Arthur A. Denny and his group of travelers, subsequently known as the Denny Party, arrived from Illinois via Portland, Oregon, on the schooner Exact at Alki Point on November 13, 1851; the settlement was moved to the eastern shore of Elliott Bay and named "Seattle" in 1852, in honor of Chief Si'ahl of the local Duwamish and Suquamish tribes. Today, Seattle has high populations of Native, Scandinavian and Asian Americans, as well as a thriving LGBT community that ranks 6th in the United States for population. Logging was Seattle's first major industry, but by the late 19th century, the city had become a commercial and shipbuilding center as a gateway to Alaska during the Klondike Gold Rush. Growth after World War II was due to the local Boeing company, which established Seattle as a center for aircraft manufacturing; the Seattle area developed into a technology center from the 1980s onwards with companies like Microsoft becoming established in the region. Internet retailer Amazon was founded in Seattle in 1994, major airline Alaska Airlines is based in SeaTac, serving Seattle's international airport, Seattle–Tacoma International Airport.
The stream of new software and Internet companies led to an economic revival, which increased the city's population by 50,000 between 1990 and 2000. Owing to its increasing population in the 21st century and the state of Washington have some of the highest minimum wages in the country, at $15 per hour for smaller businesses and $16 for the city's largest employers. Seattle has a noteworthy musical history. From 1918 to 1951, nearly two dozen jazz nightclubs existed along Jackson Street, from the current Chinatown/International District to the Central District; the jazz scene nurtured the early careers of Ray Charles, Quincy Jones, Ernestine Anderson, others. Seattle is the birthplace of rock musician Jimi Hendrix, as well as the origin of the bands Nirvana, Pearl Jam, Alice in Chains, Foo Fighters and the alternative rock movement grunge. Archaeological excavations suggest that Native Americans have inhabited the Seattle area for at least 4,000 years. By the time the first European settlers arrived, the people occupied at least seventeen villages in the areas around Elliott Bay.
The first European to visit the Seattle area was George Vancouver, in May 1792 during his 1791–95 expedition to chart the Pacific Northwest. In 1851, a large party led by Luther Collins made a location on land at the mouth of the Duwamish River. Thirteen days members of the Collins Party on the way to their claim passed three scouts of the Denny Party. Members of the Denny Party claimed land on Alki Point on September 28, 1851; the rest of the Denny Party set sail from Portland and landed on Alki point during a rainstorm on November 13, 1851. After a difficult winter, most of the Denny Party relocated across Elliott Bay and claimed land a second time at the site of present-day Pioneer Square, naming this new settlement Duwamps. Charles Terry and John Low remained at the original landing location and reestablished their old land claim and called it "New York", but renamed "New York Alki" in April 1853, from a Chinook word meaning "by and by" or "someday". For the next few years, New York Alki and Duwamps competed for dominance, but in time Alki was abandoned and its residents moved across the bay to join the rest of the settlers.
David Swinson "Doc" Maynard, one of the founders of Duwamps, was the primary advocate to name the settlement after Chief Seattle of the Duwamish and Suquamish tribes. The name "Seattle" appears on official Washington Territory papers dated May 23, 1853, when the first plats for the village were filed. In 1855, nominal land settlements were established. On January 14, 1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of trustees managing the city; the Town of Seattle was disincorporated on January 18, 1867, remained a mere precinct of King County until late 1869, when a new petition was filed and the city was re-incorporated December 2, 1869, with a mayor–council government. The corporate seal of the City of Seattle carries the date "1869" and a likeness of Chief Sealth in left profile. Seattle has a history of boom-and-bust cycles, like many other cities near areas of extensive natural and mineral resources. Seattle has risen several times economically gone into precipitous decline, but it has used those periods to rebuild solid infrastructure
Singapore the Republic of Singapore, is an island city-state in Southeast Asia. It lies one degree north of the equator, at the southern tip of the Malay Peninsula, with Indonesia's Riau Islands to the south and Peninsular Malaysia to the north. Singapore's territory consists of one main island along with 62 other islets. Since independence, extensive land reclamation has increased its total size by 23%; the country is known for its transition from a developing to a developed one in a single generation under the leadership of its founder Lee Kuan Yew. In 1819, Sir Stamford Raffles founded colonial Singapore as a trading post of the British East India Company. After the company's collapse in 1858, the islands were ceded to the British Raj as a crown colony. During the Second World War, Singapore was occupied by Japan, it gained independence from the British Empire in 1963 by joining Malaysia along with other former British territories, but separated two years over ideological differences, becoming a sovereign nation in 1965.
After early years of turbulence and despite lacking natural resources and a hinterland, the nation developed as an Asian Tiger economy, based on external trade and its workforce. Singapore is a global hub for education, finance, human capital, logistics, technology, tourism and transport; the city ranks in numerous international rankings, has been recognised as the most "technology-ready" nation, top International-meetings city, city with "best investment potential", world's smartest city, world's safest country, second-most competitive country, third least-corrupt country, third-largest foreign exchange market, third-largest financial centre, third-largest oil refining and trading centre, fifth-most innovative country, the second-busiest container port. The Economist has ranked Singapore as the most expensive city to live in, since 2013, it is identified as a tax haven. Singapore is the only country in Asia with an AAA sovereign rating from all major rating agencies, one of 11 worldwide. Globally, the Port of Singapore and Changi Airport have held the titles of leading "Maritime Capital" and "Best Airport" for consecutive years, while Singapore Airlines is the 2018 "World's Best Airline".
Singapore ranks 9th on the UN Human Development Index with the 3rd highest GDP per capita. It is placed in key social indicators: education, life expectancy, quality of life, personal safety and housing. Although income inequality is high, 90% of homes are owner-occupied. According to the Democracy Index, the country is described as a "flawed democracy"; the city-state is home to 5.6 million residents, 39% of whom are foreign nationals, including permanent residents. There are four official languages: English, Mandarin Chinese, Tamil, its cultural diversity is reflected in major festivals. Pew Research has found. Multiracialism has been enshrined in its constitution since independence, continues to shape national policies in education, politics, among others. Singapore is a unitary parliamentary republic with a Westminster system of unicameral parliamentary government; the People's Action Party has won every election since self-government began in 1959. As one of the five founding members of ASEAN, Singapore is the host of the Asia-Pacific Economic Cooperation Secretariat and Pacific Economic Cooperation Council Secretariat, as well as many international conferences and events.
It is a member of the East Asia Summit, Non-Aligned Movement and the Commonwealth of Nations. The English name of Singapore is an anglicisation of the native Malay name for the country, in turn derived from Sanskrit, hence the customary reference to the nation as the Lion City, its inclusion in many of the nation's symbols. However, it is unlikely that lions lived on the island. There are however other suggestions for the origin of the name and scholars do not believe that the origin of the name is established; the central island has been called Pulau Ujong as far back as the third century CE "island at the end" in Malay. Singapore is referred to as the Garden City for its tree-lined streets and greening efforts since independence, the Little Red Dot for how the island-nation is depicted on many maps of the world and Asia, as a red dot. Singapore is referred to as the "Switzerland of Asia" in 2017 due to its neutrality on international and regional issues; the Greco-Roman astronomer Ptolemy identified a place called Sabana in the general area in the second century, the earliest written record of Singapore occurs in a Chinese account from the third century, describing the island of Pu Luo Chung.
This was itself a transliteration from the Malay name "Pulau Ujong", or "island at the end". The Nagarakretagama, a Javanese epic poem written in 1365, referred to a settlement on the island called Tumasik. In 1299, according to the Malay Annals, the Kingdom of Singapura was founded on the island by Sang Nila Utama. Although the historicity
A torpedo bomber is a military aircraft designed to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the First World War as soon as aircraft were built that were capable of carrying the weight of a torpedo, remained an important aircraft type until they were rendered obsolete by anti-ship missiles, they were an important element in many famous Second World War battles, notably the British attack at Taranto and the Japanese attack on Pearl Harbor. Torpedo bombers first appeared prior to the First World War, they carried torpedoes designed for air launch, which were smaller and lighter than those used by submarines and surface warships. Nonetheless, as an airborne torpedo could weigh as much as 2,000 pounds, more than twice the bomb load of contemporary single-engined bombers, the aircraft carrying it needed to be specially designed for the purpose. Many early torpedo bombers were floatplanes, such as the Short 184, the undercarriage had to be redesigned so that the torpedo could be dropped from the aircraft's centerline.
While many torpedo bombers were single-engine aircraft, some multi-engined aircraft have been used as torpedo bombers, with the Mitsubishi G3M Nell and Mitsubishi G4M Betty being used in the sinking of Prince of Wales and Repulse. Other twin-engine or three-engined aircraft designed or used as torpedo bombers include the Mitsubishi Ki-67, the Savoia-Marchetti SM.79 "Sparviero", the CANT Z.1007, the Bristol Beaufort and Bristol Beaufighter, the Junkers Ju 88, the Heinkel He 111, the B-25 Mitchell and many others. Some postwar jet aircraft were adapted as torpedo bombers in the late 1950s; the last known torpedo bomber attack was made by US Navy Skyraiders against the Hwacheon Dam during the Korean War. The North Korean Air Force retired the world's last operational torpedo bombers in the 1980s. In a parallel development, many maritime strike aircraft and helicopters have been capable of launching guided torpedoes. Many naval staffs began to appreciate the possibility of using aircraft to launch torpedoes against moored ships in the period before the First World War.
Captain Alessandro Guidoni, an Italian naval captain, experimented with dropping weights from Farman MF.7 in 1912. Which led to Raúl Pateras Pescara and Guidoni developing a purpose-built torpedo bomber from which a 375 lb dummy torpedo was dropped in February 1914 but they abandoned their work shortly afterwards when the aircraft's performance proved inadequate. Admiral Bradley A. Fiske of the United States Navy took out a patent in 1912 for a torpedo carrying aircraft entitled "Method of and apparatus for delivering submarine torpedoes from airships." He suggested. Winston Churchill, as First Lord of the Admiralty from October 1911 to May 1915, was a strong proponent of naval air power, he established the Royal Naval Air Service in April 1912 and took flying lessons to foster aviation development. Churchill ordered the RNAS to torpedo bombers for the Fleet; the British Admiralty ordered the Short Admiralty Type 81 biplane floatplane as a reconnaissance aircraft. It first flew in July 1913 and was loaded aboard the cruiser HMS Hermes, converted to become the Royal Navy's first seaplane tender.
When the rival Sopwith Special, designed from the outset as a torpedo bomber, failed to lift its payload off the water, Shorts converted the Type 81 to carry torpedoes in July 1914, just before the outbreak of the First World War. On 28 July 1914, Arthur Longmore dropped the first aerial torpedo, a 14-inch 810 lb torpedo, from a Type 81 at the Royal Naval Air Station Calshot; the support wires of the floats were moved to allow the torpedo to be carried above the water and a specially designed quick-release mechanism was used. The first plane designed from the outset as a torpedo bomber was the five-seat floatplane biplane AD Seaplane Type 1000 or AD1. However, it proved to be a failure; when the prototype built by J. Samuel White from the Isle of Wight first flew in June 1916, it was found to be too heavy and its float struts too weak for operations. Remaining orders were cancelled. On 12 August 1915, a Royal Naval Air Service Short 184 floatplane torpedo bomber sank a Turkish merchantman in the Sea of Marmara.
It was operating from a seaplane carrier converted from a ferry. Fitted with an aircraft hangar, Ben-my-Chree was used to carry up to six biplanes with their wings folded back to reduce carrying space; this was the first ship sunk by air-launched torpedo. Five days another ship supplying Turkish forces in the Gallipoli campaign against British and New Zealand troops was sunk. Production of the Short 184 continued until after the Armistice of 11 November 1918, with a total of 936 built by several manufacturers, it served including the Imperial Japanese Navy, which built them under licence. The first torpedo bomber designed for operation from aircraft carriers was the Sopwith Cuckoo. First flown in June 1917, it was designed to take off from the Royal Navy's new aircraft carriers, but had to land on an airfield as arrester wires, needed to stop an aircraft during landing on a ship, had not yet been perfected; the Admiralty planned to use five carriers and 100-120 Cuckoos to attack the German High Seas Fleet, sheltering in Kiel since the Battle of Jutland in 1916 but when the war ended only 90 Cuckoos had been compl
Hawaii is the 50th and most recent state to have joined the United States, having received statehood on August 21, 1959. Hawaii is the only U. S. state located in Oceania, the only U. S. state located outside North America, the only one composed of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean; the state encompasses nearly the entire volcanic Hawaiian archipelago, which comprises hundreds of islands spread over 1,500 miles. At the southeastern end of the archipelago, the eight main islands are—in order from northwest to southeast: Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe and the Island of Hawaiʻi; the last is the largest island in the group. The archipelago is ethnologically part of the Polynesian subregion of Oceania. Hawaii's diverse natural scenery, warm tropical climate, abundance of public beaches, oceanic surroundings, active volcanoes make it a popular destination for tourists, surfers and volcanologists.
Because of its central location in the Pacific and 19th-century labor migration, Hawaii's culture is influenced by North American and East Asian cultures, in addition to its indigenous Hawaiian culture. Hawaii has over a million permanent residents, along with many visitors and U. S. military personnel. Its capital is Honolulu on the island of Oʻahu. Hawaii is the 8th-smallest and the 11th-least populous, but the 13th-most densely populated of the 50 U. S. states. It is the only state with an Asian plurality; the state's oceanic coastline is about 750 miles long, the fourth longest in the U. S. after the coastlines of Alaska and California. The state of Hawaii derives its name from the name of Hawaiʻi. A common Hawaiian explanation of the name of Hawaiʻi is that it was named for Hawaiʻiloa, a legendary figure from Hawaiian myth, he is said to have discovered the islands. The Hawaiian language word Hawaiʻi is similar to Proto-Polynesian *Sawaiki, with the reconstructed meaning "homeland". Cognates of Hawaiʻi are found in other Polynesian languages, including Māori and Samoan.
According to linguists Pukui and Elbert, "lsewhere in Polynesia, Hawaiʻi or a cognate is the name of the underworld or of the ancestral home, but in Hawaii, the name has no meaning". A somewhat divisive political issue arose in 1978 when the Constitution of the State of Hawaii added Hawaiian as a second official state language; the title of the state constitution is The Constitution of the State of Hawaii. Article XV, Section 1 of the Constitution uses The State of Hawaii. Diacritics were not used because the document, drafted in 1949, predates the use of the ʻokina and the kahakō in modern Hawaiian orthography; the exact spelling of the state's name in the Hawaiian language is Hawaiʻi. In the Hawaii Admission Act that granted Hawaiian statehood, the federal government recognized Hawaii as the official state name. Official government publications and office titles, the Seal of Hawaii use the traditional spelling with no symbols for glottal stops or vowel length. In contrast, the National and State Parks Services, the University of Hawaiʻi and some private enterprises implement these symbols.
No precedent for changes to U. S. state names exists since the adoption of the United States Constitution in 1789. However, the Constitution of Massachusetts formally changed the Province of Massachusetts Bay to the Commonwealth of Massachusetts in 1780, in 1819, the Territory of Arkansaw was created but was admitted to statehood as the State of Arkansas. There are eight main Hawaiian islands; the island of Niʻihau is managed by brothers Bruce and Keith Robinson. Access to uninhabited Kahoʻolawe island is restricted; the Hawaiian archipelago is located 2,000 mi southwest of the contiguous United States. Hawaii is the southernmost U. S. the second westernmost after Alaska. Hawaii, like Alaska, does not border any other U. S. state. It is the only U. S. state, not geographically located in North America, the only state surrounded by water and, an archipelago, the only state in which coffee is commercially cultivable. In addition to the eight main islands, the state has many smaller islets. Kaʻula is a small island near Niʻihau.
The Northwest Hawaiian Islands is a group of nine small, older islands to the northwest of Kauaʻi that extend from Nihoa to Kure Atoll. Across the archipelago are around 130 small rocks and islets, such as Molokini, which are either volcanic, marine sedimentary or erosional in origin. Hawaii's tallest mountain Mauna Kea is 13,796 ft above mean sea level; the Hawaiian islands were formed by volcanic activity initiated at an undersea magma source called the Hawaii hotspot. The process is continuing to build islands; because of the hotspot's location, all active land volcanoes are located on the southern half of Hawaii Island. The newest volcano, Lōʻihi Seamount, is located south of the coast of Hawaii Island; the last volcanic eruption outside Hawaii Island occurred
President of the United States
The president of the United States is the head of state and head of government of the United States of America. The president directs the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. In contemporary times, the president is looked upon as one of the world's most powerful political figures as the leader of the only remaining global superpower; the role includes responsibility for the world's most expensive military, which has the second largest nuclear arsenal. The president leads the nation with the largest economy by nominal GDP; the president possesses international hard and soft power. Article II of the Constitution establishes the executive branch of the federal government, it vests the executive power of the United States in the president. The power includes the execution and enforcement of federal law, alongside the responsibility of appointing federal executive, diplomatic and judicial officers, concluding treaties with foreign powers with the advice and consent of the Senate.
The president is further empowered to grant federal pardons and reprieves, to convene and adjourn either or both houses of Congress under extraordinary circumstances. The president directs the foreign and domestic policies of the United States, takes an active role in promoting his policy priorities to members of Congress. In addition, as part of the system of checks and balances, Article I, Section 7 of the Constitution gives the president the power to sign or veto federal legislation; the power of the presidency has grown since its formation, as has the power of the federal government as a whole. Through the Electoral College, registered voters indirectly elect the president and vice president to a four-year term; this is the only federal election in the United States, not decided by popular vote. Nine vice presidents became president by virtue of a president's intra-term resignation. Article II, Section 1, Clause 5 sets three qualifications for holding the presidency: natural-born U. S. citizenship.
The Twenty-second Amendment precludes any person from being elected president to a third term. In all, 44 individuals have served 45 presidencies spanning 57 full four-year terms. Grover Cleveland served two non-consecutive terms, so he is counted twice, as both the 22nd and 24th president. Donald Trump of New York is the current president of the United States, he assumed office on January 20, 2017. In July 1776, during the American Revolutionary War, the Thirteen Colonies, acting jointly through the Second Continental Congress, declared themselves to be 13 independent sovereign states, no longer under British rule. Recognizing the necessity of coordinating their efforts against the British, the Continental Congress began the process of drafting a constitution that would bind the states together. There were long debates on a number of issues, including representation and voting, the exact powers to be given the central government. Congress finished work on the Articles of Confederation to establish a perpetual union between the states in November 1777 and sent it to the states for ratification.
Under the Articles, which took effect on March 1, 1781, the Congress of the Confederation was a central political authority without any legislative power. It could make its own resolutions and regulations, but not any laws, could not impose any taxes or enforce local commercial regulations upon its citizens; this institutional design reflected how Americans believed the deposed British system of Crown and Parliament ought to have functioned with respect to the royal dominion: a superintending body for matters that concerned the entire empire. The states were out from under any monarchy and assigned some royal prerogatives to Congress; the members of Congress elected a President of the United States in Congress Assembled to preside over its deliberation as a neutral discussion moderator. Unrelated to and quite dissimilar from the office of President of the United States, it was a ceremonial position without much influence. In 1783, the Treaty of Paris secured independence for each of the former colonies.
With peace at hand, the states each turned toward their own internal affairs. By 1786, Americans found their continental borders besieged and weak and their respective economies in crises as neighboring states agitated trade rivalries with one another, they witnessed their hard currency pouring into foreign markets to pay for imports, their Mediterranean commerce preyed upon by North African pirates, their foreign-financed Revolutionary War debts unpaid and accruing interest. Civil and political unrest loomed. Following the successful resolution of commercial and fishing disputes between Virginia and Maryland at the Mount Vernon Conference in 1785, Virginia called for a trade conference between all the states, set for September 1786 in Annapolis, with an aim toward resolving further-reaching interstate commercial antagonisms; when the convention failed for lack of attendance due to suspicions among most of the other states, Alexander Hamilton led the Annapolis delegates in a call for a convention to offer revisions to the Articles, to be held the next spring in Philadelphia.
Prospects for the next convention appeared bleak until James Madison and Edmund Randolph succeeded in securing George Washington's attendance to Philadelphia as a delegate for Virginia. When the Constitutional Convention convened in May 1787, the 12 state delegations in attendance (Rh
A cruiser is a type of warship. Modern cruisers are the largest ships in a fleet after aircraft carriers and amphibious assault ships, can perform several roles; the term has been in use for several hundred years, has had different meanings throughout this period. During the Age of Sail, the term cruising referred to certain kinds of missions – independent scouting, commerce protection, or raiding – fulfilled by a frigate or sloop-of-war, which were the cruising warships of a fleet. In the middle of the 19th century, cruiser came to be a classification for the ships intended for cruising distant waters, commerce raiding, scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big as a pre-dreadnought battleship. With the advent of the dreadnought battleship before World War I, the armored cruiser evolved into a vessel of similar scale known as the battlecruiser; the large battlecruisers of the World War I era that succeeded armored cruisers were now classified, along with dreadnought battleships, as capital ships.
By the early 20th century after World War I, the direct successors to protected cruisers could be placed on a consistent scale of warship size, smaller than a battleship but larger than a destroyer. In 1922, the Washington Naval Treaty placed a formal limit on these cruisers, which were defined as warships of up to 10,000 tons displacement carrying guns no larger than 8 inches in calibre; some variations on the Treaty cruiser design included the German Deutschland-class "pocket battleships" which had heavier armament at the expense of speed compared to standard heavy cruisers, the American Alaska class, a scaled-up heavy cruiser design designated as a "cruiser-killer". In the 20th century, the obsolescence of the battleship left the cruiser as the largest and most powerful surface combatant after the aircraft carrier; the role of the cruiser varied according to ship and navy including air defense and shore bombardment. During the Cold War, the Soviet Navy's cruisers had heavy anti-ship missile armament designed to sink NATO carrier task forces via saturation attack.
The U. S. Navy built guided-missile cruisers upon destroyer-style hulls designed to provide air defense while adding anti-submarine capabilities, being larger and having longer-range surface-to-air missiles than early Charles F. Adams guided-missile destroyers tasked with the short-range air defense role. By the end of the Cold War, the line between cruisers and destroyers had blurred, with the Ticonderoga-class cruiser using the hull of the Spruance-class destroyer but receiving the cruiser designation due to their enhanced mission and combat systems. Indeed, the newest U. S. and Chinese destroyers are more armed than some of the cruisers that they succeeded. Only two nations operate cruisers: the United States and Russia, in both cases the vessels are armed with guided missiles. BAP Almirante Grau was the last gun cruiser in service, serving with the Peruvian Navy until 2017; the term "cruiser" or "cruizer" was first used in the 17th century to refer to an independent warship. "Cruiser" meant the mission of a ship, rather than a category of vessel.
However, the term was nonetheless used to mean a faster warship suitable for such a role. In the 17th century, the ship of the line was too large and expensive to be dispatched on long-range missions, too strategically important to be put at risk of fouling and foundering by continual patrol duties; the Dutch navy was noted for its cruisers in the 17th century, while the Royal Navy—and French and Spanish navies—subsequently caught up in terms of their numbers and deployment. The British Cruiser and Convoy Acts were an attempt by mercantile interests in Parliament to focus the Navy on commerce defence and raiding with cruisers, rather than the more scarce and expensive ships of the line. During the 18th century the frigate became the preeminent type of cruiser. A frigate was a small, long range armed ship used for scouting, carrying dispatches, disrupting enemy trade; the other principal type of cruiser was the sloop, but many other miscellaneous types of ship were used as well. During the 19th century, navies began to use steam power for their fleets.
The 1840s sloops. By the middle of the 1850s, the British and U. S. Navies were both building steam frigates with long hulls and a heavy gun armament, for instance USS Merrimack or Mersey; the 1860s saw the introduction of the ironclad. The first ironclads were frigates, in the sense of having one gun deck. In spite of their great speed, they would have been wasted in a cruising role; the French constructed a number of smaller ironclads for overseas cruising duties, starting with the Belliqueuse, commissioned 1865. These "station ironclads" were the beginning of the development of the armored cruisers, a type of ironclad for the traditional cruiser missions of fast, independent raiding and patrol; the first true armored cruiser was the Russian General-Admiral, completed in 1874, followed by the British Shannon a few years later. Until the 1890s armored cr
