EIFFEL TOWER

Named after its designer, engineer Gustave Eiffel, the Eiffel Tower is the tallest building in Paris.More than 200,000,000 have visited the tower since its construction in 1889,including 6,719,200 in 2006,making it the most visited paid monument in the world.Including the 24 m (79 ft) antenna, the structure is 325 m (1,063 ft) high (since 2000), which is equivalent to about 81 levels in a conventional building.

Eiffel Tower October 2007
When the tower was completed in 1889 it was the world's tallest tower — a title it retained until 1930 when New York City's Chrysler Building (319 m — 1,047 ft tall) was completed.The tower is now the fifth-tallest structure in France and the tallest structure in Paris, with the second-tallest being the Tour Montparnasse (210 m — 689 ft), although that will soon be surpassed by Tour AXA (225.11 m — 738.36 ft).

The metal structure of the Eiffel Tower weighs 7,300 tonnes while the entire structure including non-metal components is approximately 10,000 tonnes. Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 18 cm (7 in) because of thermal expansion of the metal on the side facing the sun. The tower also sways 6–7 cm (2–3 in) in the wind.As demonstration of the economy of design, if the 7300 tonnes of the metal structure were melted down it would fill the 125 meter square base to a depth of only 6 cm (2.36 in), assuming a density of the metal to be 7.8 tonnes per cubic meter. The tower has a mass less than the mass of the air contained in a cylinder of the same dimensions, that is 324 meters high and 88.3 meters in radius. The weight of the tower is 10,100 tonnes compared to 10,265 tonnes of air.

ROSE TOWER

The Rose Tower is a 333-metre (1,093-feet), 72-story skyscraper on Sheikh Zayed Road in Dubai, United Arab Emirates. Originally, the tower was to be 380 m (1,247 ft.) high, but its projected height was reduced in further design modification. Construction began in 2004. ACC (Arabian Construction Co.) was the general contractor. On 24 October 2006, the building reached its full height with the addition of the spire. Although the tower was expected to open in April 2008, it still had not opened by October 2008. Once open, it is expected to become the world's tallest hotel.This hotel, known as "Rose Rotana Suites", will surpass both the 321m (1,053ft) Burj Al Arab, and the incomplete 330m (1,083ft) Ryugyong Hotel in Pyongyang, North Korea.

HEARST TOWER (CHARLOTTE)

The Hearst Tower in Charlotte, North Carolina is a 47-story skyscraper that rises 659 feet (201 m) in height. It was first opened on 14 November 2002 and is the 2nd-tallest building in Charlotte. The 32-story tower rest atop a 15-floor podium. Located within the podium is a three story, 180,000 square-foot trading floor designed by Skidmore, Owings & Merrill, and operated by Bank of America. The building is currently owned by Bank of America, although the Hearst Corporation also has offices in the building. The building's reverse floorplate design makes the upper floors averaging 24,000 square feet compared to an average of only 20,000 square feet for the lower floors. There are brass railings designed by Edgar Brandt, which were rescued from an Au Bon Marche department store in Paris, located in the College Street lobby. The Hearst Plaza, a 160 by 65 foot public plaza lined with restaurants, shops, and the Mint Museum of Craft + Design, is located next to the main entrance off North Tryon Street. In front of the plaza is a 10-foot glass and bronze sculpture crafted by Howard Ben Tre entitled the Castellan, which translates to "keeper of the castle." Within in the lobby is the Bank of America Gallery, it contains priceless pieces of art and is open to the public during regular business hours. It is located across the street from the Bank of America Corporate Center and 201 North Tryon.

HEARST TOWER (NY)

Hearst Tower in New York City, New York is located at 300 West 57th Street, 959 8th Avenue, near Columbus Circle. It is the world headquarters of the Hearst Corporation, bringing together for the first time their numerous publications and communications companies under one roof, including among others Cosmopolitan, Esquire and the San Francisco Chronicle.
The former six-story headquarters building was commissioned by the founder, William Randolph Hearst and awarded to the architect Joseph Urban. The building was completed in 1928 at a cost of $2 million and contained 40,000 sq ft (3,700 m2). The original cast stone facade has been preserved in the new design as a designated Landmark site. Originally built as the base for a proposed skyscraper, the construction of the tower was postponed due to the Great Depression. The new tower addition was completed nearly eighty years later, and 2000 Hearst employees moved in on 4 May 2006.
The tower – designed by the architect Norman Foster, structural engineered by WSP Cantor Seinuk, and constructed by Turner construction – is 46 stories tall, standing 182 m (597 ft) with 80,000 m² (856,000 ft²) of office space. The uncommon triangular framing pattern (also known as a diagrid) required 9,500 metric tons (10,480 tons) of structural steel – reportedly about 20% less than a conventional steel frame. Hearst Tower was the first skyscraper to break ground in New York City after September 11, 2001. The building received the 2006 Emporis Skyscraper Award, citing it as the best skyscraper in the world completed that year.
Hearst Tower is the first "green" high rise office building completed in New York City, with a number of environmental considerations built into the plan. The floor of the atrium is paved with heat conductive limestone. Polyethylene tubing is embedded under the floor and filled with circulating water for cooling in the summer and heating in the winter. Rain collected on the roof is stored in a tank in the basement for use in the cooling system, to irrigate plants and for the water sculpture in the main lobby. The building was constructed using 80% recycled steel. Overall, the building has been designed to use 25% less energy than the minimum requirements for the city of New York, and earned a gold designation from the United States Green Building Council’s LEED certification program.
The atrium features escalators which run through a 3-story water sculpture titled Icefall, a wide waterfall built with thousands of glass panels, which cools and humidifies the lobby air. The water element is complemented by a 70-foot (21.3 m) tall fresco painting entitled Riverlines by artist Richard Long.

SEA MINK

The Sea Mink, Neovison macrodon, is an extinct North American member of the Mustelidae family. It is the only mustelid, and one of two mammalian carnivore species to have gone extinct in historic times, along with the Falkland Islands Wolf. It was significantly longer than the closely related American Mink (N. vison), and bulkier, leading to a pelt that was almost twice the size of the other species. The longest specimen recorded was said to be 82.6 cm (32.5 in). The fur of the Sea Mink was said to be coarser and redder than the American Mink's, and to give off a distinctive odor.
It was found along the rocky coasts of New England and Atlantic Canada, as far north as Nova Scotia. It was not a truly marine species, being confined to coastal waters. The Labrador Duck, with which it co-existed, may have been a prey item.
Due to its highly prized fur, this mink was hunted to extinction. The animal's remains are often found in Native American shell-heaps on the coasts of the islands of Maine, but while indigenous hunting may have had some contribution to the Sea Mink's decline, it was the competitive European fur trade that led to its extinction.
The last known member of the species was said to have been captured in New Brunswick, New Jersey in 1894, although there is some debate if this was a specimen of N. macrodon or N. vison. The last substantiated report has led to an estimated extinction date of around 1860,although a specimen was reported as sold to a fur-buyer in Maine in 1880.
Although well known to fur hunters, it became extinct before being scientifically described, and therefore little is known about its habits. Existing data suggests it was nocturnal and solitary.
The Sea Mink is sometimes considered a subspecies of the American Mink, in which case the name Neovison vison macrodon is used

taRpaN

TARPAN

The Tarpan, Equus ferus ferus, was the Eurasian wild horse. The last specimen of this species died in captivity in Ukraine in 1876. The name Tarpan is from a Turkic language (Kyrgyz or Kazakh) name for the horse.
Several attempts have been made to re-create the Tarpan, beginning in the 1930s. The breeds that resulted included the Heck horse, the Hegardt or Stroebel's horse, and a derivation of the Konik breed - all of which closely resembled the original Tarpan.

BAKUN DAM

The Bakun Hydroelectric Project is located in Sarawak, Malaysia on the Balui River, a tributary or source of the Rajang River and some sixty kilometers west of Belaga.As part of the project, the tallest concrete-faced rockfill dam in the world would be built. This would also be the largest dam in Asia outside of China. It is expected to generate 2,400 megawatts (MW) of electricity once completed.
The purpose for the dam was to meet growing demand for electricity. However, most of this demand said to lie in Peninsular Malaysia and not East Malaysia, where the dam is located. Even in Peninsular Malaysia, however, there is an over-supply of electricity, with Tenaga Nasional Berhad being locked into unfavourable purchasing agreements with Independent Power Producers. The original idea was to have 30% of the generated capacity consumed in East Malaysia and the rest sent to Peninsular Malaysia. This plan envisioned 730 km of overhead HVDC transmission lines in East Malaysia, 670 km of undersea HVDC cable and 300 km of HVDC transmission line in Peninsular Malaysia.
Future plans for the dam include connecting it to an envisioned Trans-Borneo Power Grid Interconnection, which would be a grid to supply power to Sarawak, Sabah, Brunei, and Kalimantan (Indonesia). There have been mentions of this grid made within ASEAN meetings but no actions have been taken by any party.

GREERS FERRY

The dam is located at 35°31′15″N 91°59′36″W / 35.52083, -91.99333 north of Little Rock. It was dedicated in October, 1963 by President John F. Kennedy just one month before his assassination. This event marks the only time a sitting president has visited Cleburne County.
Construction of the dam began in March 1959 and was completed in December 1962. The lake serves the Heber Springs area flood control, and is a site for recreation and power generation. When construction began on the dam in 1956, hundreds of workers showed up looking for work. The newly-hired workers then rented empty houses next to the construction site, and workers were even building their own homes next to the soon-to-be lake. Once all the workers arrived, people and business owners saw an opportunity in this construction and built motels, shops, and stores next to the construction site so workers would have a place to shop and relax. Farmers also felt the benefit of the construction, as work on the lake created demand for livestock and agriculture.
After completion, the lake was dedicated on October 3, 1963 by John F. Kennedy.The trip was his last major public appearance before his fateful trip to Dallas on Nov. 22, 1963, where he was assassinated. In his remarks in Heber Springs, Kennedy explained that the Greers Ferry project and others like it were investments in Arkansas and the nation's future. He was right - after the lake filled, tourism boomed, many businesses reopened, and Greers Ferry Lake became one of Arkansas' leading destinations. Today, many resort communities dot the shores of Greers Ferry Lake.

OLYMPIC DAM

Olympic Dam Coordinates: 30°26′14.02″S 136°53′19.23″E / -30.4372278, 136.888675 is a mining centre in South Australia located some 550 km NNW of Adelaide the capital city of South Australia. It is the site of an extremely large deposit of copper, uranium, gold and silver, which supports an underground mine as well as an integrated metallurgical processing plant. It is the largest known single deposit of uranium in the world, though uranium represents only a minority of the mine's total revenue.The deposit was discovered by Western Mining Corporation in 1975 and started production in 1987. It now belongs to BHP Billiton, which acquired WMC Resources in 2005. The mine currently operates by an underground mining method called sublevel open stoping, using modern and highly productive mining equipment. The March 2005 mine production rate is an annualised 9.1 million tonnes making it one of Australia's larger mines. 2005 metal production is thought to be in excess of 220,000 tonnes of copper, 4500 tonnes of uranium oxide, plus gold and silver. The copper and uranium oxide are exported through Port Adelaide. Most of the mine workers live in the nearby towns of Roxby Downs and Andamooka. Regular flights to Olympic Dam Airport service Olympic Dam.
The Olympic Dam mine uses 35 million litres of Great Artesian Basin water each day, making it the largest industrial user of underground water in the southern hemisphere.

TEMENGGOR DAM

The Temenggor Dam or Temenggor Power Station is a major hydroelectric dam in Gerik, Perak, Malaysia. It is located on Sungai Perak about 200 km northeast of Ipoh. Construction of the dam formed a large lake, Temenggor Lake.The power station is a hydroelectric power station, using 4 Hitachi turbines of 87 MW installed capacity. The station is operated by Tenaga Nasional. Since 1987 Temenggor has been unmanned and is remotely operated via a SCADA system at the Bersia Group Control Centre. In the late 1990s, facilities were added to enable Automatic Generation Control by TNB's National Load Despatch Centre in Kuala Lumpur.Temenggor Dam is now the third largest dam in Malaysia. It was once the largest dam and largest hydroelectric generation facility upon completion in 1979, before being overtaken by the Kenyir Dam in 1985. It holds a special place in the history of Malaysia for its military role in flooding the Upper Perak River and cutting off the communist terrorists' infiltration route from the Betong salient in Thailand.
Maximum height above foundation of 127 m, and crest length of 258 m, volume of fill is xx.00 million cubic metres.Crest elevation is 250 m above sea level (ASL), maximum flood level is 248 m, operating levels maximum 245 m and minimum 200 m.Reservoir area at 245 m ASL is 152 km², and with a catchment area of x,000 km².

IMPERIAL DAM

The Imperial Dam is a dam near Yuma, Arizona (USA), built in the 1930s. It diverts Colorado River water into three different canals and holds the river water until it can be directed into a desilting plant before being released into the All-American Canal, the Gila River, and the Yuma project aqueduct. While it was being built between 1932 and 1940, the Imperial Irrigation District (IID) relied on water from two temporary canals: the Inter-California canal and the Imperial canal (Alamo river).
The dam was built with three sections; the gates of each section hold back the water to help divert the water towards the desilting plant. Three giant desilting basins and seventy-two 770 foot (230 m) long scrapers hold and desilt the water; the removed silt is carried away by six sludge-pipes running under the Colorado River that dump the sediment into the California sluiceway, which returns the silt to the Colorado River. The water is now directed back towards one of the three sections which divert the water into one of the three channels. About 90% of the volume of the Colorado River is diverted into the canals at this local. Diversions can near 40,000 ft³/s (1,100 m³/s), roughly the volume of the Susquehanna River and more than 50 times the natural volume of the Rio Grande River.
The Gila River and the Yuma project aqueduct branch off towards Arizona while the All-American canal branches southwards for 37 miles (60 km) before reaching its headworks on the California border and bends west towards the Imperial Valley.
Though the All-American canal moves billions of gallons of water into Imperial Valley every year, millions of it are lost due to seepage problems. IID and Mexican authorities are debating on whether or not to line the All-American canal with concrete. The Mexican authorities are opposed to the All-American canal lining project, as the leaking water allows Mexican farmers to irrigate their crops with well-water.

GLEN CANYON

Glen Canyon Dam is a dam on the Colorado River at Page, Arizona, USA, operated by the United States Bureau of Reclamation. The purpose of the dam is to provide water storage for the arid southwestern United States, and to generate electricity for the region's growing population. Damming the river flooded Glen Canyon and created a large reservoir called Lake Powell. Just downstream from the dam is an arch bridge that carries U.S. Route 89. Also nearby is the 2280 megawatt, coal-fired Navajo Generating Station.

CLYDE DAM

There was considerable controversy when the dam was planned as to whether it was needed, and because it would flood many houses and orchards upstream at Cromwell, as well as the scenic Cromwell Gorge, which was a highlight of the then young but growing New Zealand tourism industry. Construction would also require the closure of the Otago Central Railway beyond Clyde, though materials for the dam would provide significant traffic for the rest of the line, which was experiencing a drop in freight tonnage.
The dam was constructed, following the passing of enabling legislation, as part of Prime Minister Sir Robert Muldoon's Think Big projects of the late 1970s and early 1980s, creating Lake Dunstan. The power station has a capacity of four 120 MW francis turbines (for a total of 480MW), but is only allowed to run 432 MW due to resource consent conditions. The dam was built such that two further penstocks and turbines could be installed, but if they were installed there will not be enough water to keep them running.

hUme daM

HUME DAM

The Hume Power Station is a 58-megawatt hydro-electric power station installed in the dam wall, and is primarily used for peak-load generation.
Constructed over a 12-year period from 1919 to 1931 with a workforce of thousands, it was extended during the 1950s, and completed in 1961, necessitating the wholesale removal of Tallangatta township and its re-establishment at a new site eight kilometres west of the original.
As it is the furthest downstream of the major reservoirs on the Murray River system, and has the capacity to release water at the fastest rate, Lake Hume is used by the irrigation authorities as the storage of first resort. The reservoir typically falls to less than one-third capacity by March each year, but in normal years refills to at least two-thirds capacity before November, though Australia's highly unpredictable climatic conditions cause these figures to vary quite significantly from year to year. In 2007 Lake Hume fell to a scant 1% capacity, barely more than the water in the two rivers (Murray and Mitta) flowing through on their original paths.
Monitoring of the dam in the early 1990s revealed that the water pressure and leakage had caused the dam to move on its foundations slightly, leading to concerns that the dam was heading for collapse, threatening Albury-Wodonga and the entire Murray basin with it. Authorities denied any short-term threat. Traffic was banned from the spillway, and a large repair job commenced involving, in part, the construction of a secondary earth wall behind the original to take the strain.

COULEE DAM

Grand Coulee Dam is a hydroelectric gravity dam on the Columbia River in the U.S. state of Washington. In the United States, it is the largest electric power producing facility and the largest concrete structure.It is the fourth largest producer of hydroelectricity in the world. The top producing dams are the Three Gorges Dam in China, the Guri Dam in Venezuela, and the Itaipu Dam on the border of Paraguay and Brazil.
The reservoir is called Franklin Delano Roosevelt Lake, named after the United States President who presided over the completion of the dam. The foundation was built by the MWAK Company, a joint effort of several contractors united for this purpose. Consolidated Builders Incorporated, including industrialist Henry J. Kaiser, completed the dam. The United States Bureau of Reclamation supervised the contractors and operates the dam. Folk singer Woody Guthrie was commissioned by the Bonneville Power Administration to write songs about the Columbia Basin Project; the songs Roll On Columbia and Grand Coulee Dam are part of that series.
The Grand Coulee Dam is almost a mile long at 5223 feet (1586 m). The spillway is 1,650 feet(503 m) wide. At 550 feet (168 m), it is taller than the Great Pyramid of Giza; all the pyramids at Giza could fit within its base. Its hydraulic height of 380 feet (115 m) is more than twice that of Niagara Falls. There is enough concrete to build a four-foot wide, four-inch deep sidewalk twice around the equator

HOOVER DAM

Hoover Dam, also sometimes known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Arizona and Nevada. When completed in 1935, it was both the world's largest electric-power generating station and the world's largest concrete structure. It was surpassed in both these respects by the Grand Coulee Dam in 1945. It is currently the world's 35th-largest hydroelectric generating station.
This dam, located 30 miles (48 km) southeast of Las Vegas, Nevada, is named after Herbert Hoover, who played an instrumental role in its construction, first as the Secretary of Commerce and then later as the President of the United States. Construction began in 1931 and was completed in 1935, more than two years ahead of schedule. The dam and the power plant are operated by the Bureau of Reclamation of the U.S. Department of the Interior. Listed on the National Register of Historic Places in 1981, Hoover Dam was designated a National Historic Landmark in 1985.
Lake Mead is the reservoir created behind the dam, named after Elwood Mead, who oversaw the construction of the dam.

VERZASCA DAM

The Contra dam (or Verzasca dam) is a 220-meter high arch hydroelectric dam in the Val Verzasca, Switzerland. It was constructed between 1960 and 1965.
The dam forms Lago di Vogorno, an artificial reservoir. It was designed by Lombardi Engineering. Made of concrete, the structure dams the Verzasca River and retains over 100 million cubic meters of water. The builder and owner is Verzasca SA, an electricity generator which has an 80-year concession to expire in 2046.It generates 105MW of electricity. The designer, Dr. Lombardi, considers it one of his most aesthetically pleasing dams, primarily because of the slenderness of the concrete arch; the smaller volume of concrete also kept construction costs low.It is the 25th tallest dam in the world.
The dam is one of several at which the filling of the reservoir has triggered small earthquakes.
The dam leases access to a commercial bungee jump operator. The opening scene of the 1995 James Bond film GoldenEye was filmed here. In the film the dam doubles as the fictional Arkhangelsk Chemical Weapons Facility located in the northern Soviet Union during the Cold War.

TAIPEI 101

Taipei 101 (traditional Chinese; simplified Chinese; pinyin: Táiběi Yīlíngyī; Wade-Giles: T'ai-pei I-ling-i; POJ: Tai-pak yat-leng-yat) is a 101-floor landmark skyscraper located in Xinyi District, Taipei, Taiwan. The building, designed by C.Y. Lee & partners and constructed primarily by KTRT Joint Venture and Samsung Engineering & Construction, is the world's tallest completed skyscraper according to the CTBUH, the arbiter of tall building height. Taipei 101 received the Emporis Skyscraper Award in 2004. It has been hailed as one of the Seven New Wonders of the World (Newsweek magazine, 2006) and Seven Wonders of Engineering (Discovery Channel, 2005).
The building contains 101 floors above ground and 5 floors underground. Its postmodern style combines Asian and international modern and traditional elements. It is designed to withstand typhoons and earthquakes. A multi-level shopping mall adjoining the tower houses hundreds of fashionable stores, restaurants and clubs. Fireworks launched from Taipei 101 feature prominently in international New Year's Eve broadcasts, and the tower appears frequently in films, television shows, print publications, anime media, games, and other elements of popular culture.[citation needed]
The name of the tower reflects its location in Taipei's international business district (101 mailing code) as well as its floor count. (See also "Symbolism" below.) The number is pronounced in English simply as One Oh One and in Mandarin and other local languages by the equivalent.
Taipei 101 is owned by the Taipei Financial Center Corporation and managed by the International division of Urban Retail Properties Corporation based in Chicago. The name originally planned for the building, Taipei World Financial Center, was derived from the name of the owner. The original name in Chinese was literally, Taipei International Financial Center (traditional Chinese: 臺北國際金融中心; pinyin: Táiběi Guójì Jīnróng Zhōngxīn).
Taipei 101 was overtaken in height on 2007-08-21 by the Burj Dubai in Dubai, UAE, upon the completion of that building's 141st floor . As of November 2008, the title of "world's tallest building" still rests with Taipei 101, as international architectural standards define a "building" as a structure capable of being fully occupied. The Burj Dubai will claim the title upon its completion, which is expected in September 2009.

MILLENIUM TOWER WORLD BUSINESS CENTER

The Millennium Tower World Business Center is an approved supertall skyscraper which The Solomon Group, a private Korean developer, intends to move forward with Asymptote’s design for a 560m tall tower, which upon completion will be the tallest building in Asia. Asymptote’s three-towered design for the World Business Center Busan is a newly minted approach where the notion of singularity and autonomy gives way to a strong juxtaposition of form and voids.

Simultaneously a single entity, the towers are also read as three distinct forms set against Busan’s dramatic natural backdrop of sea and mountains. The base of the tower artfully negotiates the site at the entrance level while from the top of the midsection the three slender towers rise above the skylobby level and gracefully taper upwards around a spectacular central void. Through its formal and sculptural qualities this unique architectural expression is a powerful symbol of 21st century Busan and a beacon for it’s trajectory into the future and onto the global stage.

A jet engine is a reaction engine that discharges a fast moving jet of fluid to generate thrust in accordance with Newton's laws of motion. This broad definition of jet engines includes turbojets, turbofans, rockets, ramjets, pulse jets and pump-jets. In general, most jet engines are internal combustion engines but non-combusting forms also exist.
In common usage, the term 'jet engine' generally refers to an internal combustion duct engine, which typically consists of an engine with a rotary air compressor powered by a turbine ("Brayton cycle"), with the leftover power providing thrust via a propelling nozzle. These types of jet engines are primarily used by jet aircraft for long distance travel. The early jet aircraft used turbojet engines which were relatively inefficient for subsonic flight. Modern subsonic jet aircraft usually use high-bypass turbofan engines which help give high speeds as well as, over long distances, giving better fuel efficiency than many other forms of transport.
About 7.2% of the oil used in 2004 was ultimately consumed by jet engines.In 2007, the cost of jet fuel, while highly variable from one airline to another, averaged 26.5% of total operating costs, making it the single largest operating expense for most airlines.

TANK

A tank is a tracked, armoured fighting vehicle designed for front-line combat which combines operational mobility and tactical offensive and defensive capabilities. Firepower is normally provided by a large-calibre main gun in a rotating turret and secondary machine guns, while heavy armour and all-terrain mobility provide protection for the tank and its crew, allowing it to perform all primary tasks of the armoured troops on the battlefield.
Tanks were first manufactured during World War I in an effort to break the bloody deadlock of trench warfare. The British Army was the first to field a vehicle that combined three key characteristics: mobility over barbed wire and rough terrain, armour to withstand small arms fire and shrapnel and the firepower required to suppress or destroy machine gun nests and pillboxes. Despite some success and a significant psychological effect on the German infantry, "the tank in 1918 was not a war-winning weapon."
Interwar developments culminated in the blitzkrieg employed by the German Wehrmacht during World War II and the contribution of the panzers to this doctrine. Hard lessons learned by the Allies during World War II cemented the reputation of the tank, appropriately employed in combined arms forces, as "indispensable to success in both tactical and strategic terms."Today, tanks seldom operate alone, being organized into armoured units and operating in combined-arms formations. Despite their apparent invulnerability, without support, tanks are vulnerable to anti-tank artillery, helicopters and aircraft, enemy tanks, anti-tank and improvised mines, and (at close range or in urban environments) infantry.
Due to its formidable capabilities and versatility the battle tank is generally considered a key component of modern armies,but recent thinking has challenged the need for such powerful and expensive weaponry in a period characterized by unconventional and asymmetric warfare.Ongoing research and development attempts to equip the tank to meet the challenges of the 21st century.

AIRSHIPS

An airship or dirigible is a lighter-than-air aircraft that can be steered and propelled through the air using rudders and propellers or other thrust. Unlike other aerodynamic aircraft such as fixed-wing aircraft and helicopters, which produce lift by moving a wing or airfoil through the air, aerostatic aircraft, such as airships and hot air balloons, stay aloft by filling a large cavity, such as a balloon, with a lifting gas. A Zeppelin is a brand name for rigid airships historically built by either the Luftschiff Zeppelin company of Germany or the Goodyear Zeppelin company of the USA, and now of smaller semi-rigid airships built by Zeppelin Luftschifftechnik, also of Germany.
The main types of airship are non-rigid (or blimps), semi-rigid and rigid. Blimps are small airships without internal skeletons. Semi-rigid airships are slightly larger and have some form of internal support such as a fixed keel. Rigid airships with full skeletons, such as the massive Zeppelin transoceanic models, all but disappeared after several high-profile catastrophic accidents during the mid-20th century.
Airships were the first aircraft to make controlled, powered flight, and were widely used before the 1940s, but their use decreased over time as their capabilities were surpassed by those of airplanes. Their decline continued with a series of high-profile accidents, including the 1937 burning of the hydrogen-filled Hindenburg near Lakehurst, New Jersey, and the destruction of the USS Akron. Airships are still used today in certain niche applications, such as advertising, as camera platforms for sporting events, and as aerial observation and interdiction platforms, where the ability to hover in one place for an extended period outweighs the need for speed and maneuverability.

SUBMARINE

A submarine is a watercraft capable of independent operation below water. It differs from a submersible that has only limited underwater capability. The term submarine most commonly refers to large manned autonomous vessels, however historically or more casually, submarine can also refer to medium sized or smaller vessels, (midget submarines, wet subs), Remotely Operated Vehicles or robots. The word submarine was originally an adjective meaning "under the sea", and so consequently other uses such as "submarine engineering" or "submarine cable" may not actually refer to submarines at all. Submarine was shortened from the term "submarine boat".
Submarines are referred to as "boats" for historical reasons because vessels deployed from a ship are referred to as boats. The first submarines were launched in such a manner. The English term U-Boat for a German submarine comes from the German word for submarine, U-Boot, itself an abbreviation for Unterseeboot ("undersea boat").
Although experimental submarines had been built before, submarine design took off during the 19th century. Submarines were first widely used in World War I, and feature in many large navies. Military usage ranges from attacking enemy ships or submarines, aircraft carrier protection, blockade running, ballistic missile submarines as part of a nuclear strike force, reconnaissance, conventional land attack (for example using a cruise missile), and covert insertion of special forces. Civilian uses for submarines include marine science, salvage, exploration and facility inspection/maintenance. Submarines can also be specialised to a function such as search and rescue, or undersea cable repair. Submarines are also used in tourism and for academic research

SUBMERSIBLES

A submersible is a type of underwater vessel with limited mobility which is typically transported to its area of operation by a surface vessel or large submarine. Used by oceanographers and marine scientists. Apart from size, the technical difference between a 'submersible' and a 'submarine' is that submersibles are not totally autonomous. They may rely on a support facility or vessel for charging of batteries, high pressure air, high pressure oxygen replenishment, or all of these. The main problem with submersibles is that they may be relatively small, holding only a small crew.
A submersible vessel has greater mobility, using propeller screws or pump-jets, than submersible chambers (diving chambers or diving bells), which are suspended from a cable and winch operated from the diving support vessel.

ROCKETS

A rocket or rocket vehicle is a missile, aircraft or other vehicle which obtains thrust by the reaction of the rocket to the ejection of fast moving fluid from a rocket engine. Chemical rockets work by the action of hot gas produced by the combustion of the propellant against the inside of combustion chambers and expansion nozzles. This generates forces that accelerate the gas to extremely high speed and exert a large thrust on the rocket (since every action has an equal and opposite reaction).
The history of rockets goes back to at least the 13th century.By the 20th century, they have enabled human spaceflight to the Moon. In the 21st century, they have made commercial space tourism possible.
Rockets are used for fireworks and weaponry, as launch vehicles for artificial satellites, human spaceflight and exploration of other planets. While inefficient for low speed use, they are, compared to other propulsion systems, very lightweight and powerful, capable of generating large accelerations and of attaining extremely high speeds with reasonable efficiency.
Chemical rockets store a large amount of energy in an easily-released form, and can be very dangerous. However, careful design, testing, construction, and use minimizes risks.
