Operation Linebacker
Operation Linebacker was the codename of a U.S. Seventh Air Force and U.S. Navy Task Force 77 air interdiction campaign conducted against North Vietnam from 9 May to 23 October 1972, during the Vietnam War. Its purpose was to halt or slow the transportation of supplies and materials for the ''Nguyen Hue Offensive'' (known in the West as the Easter Offensive), an invasion of the South Vietnam by the North Vietnamese People's Army of Vietnam (PAVN) that had been launched on 30 March. ''Linebacker'' was the first continuous bombing effort conducted against North Vietnam since the end of Operation Rolling Thunder in November 1968. Nguyen Hue Offensive At midday on 30 March 1972, 30,000 PAVN troops, supported by regiments of tanks and artillery, rolled southward across the Demilitarized Zone (DMZ) that separated the two Vietnams. This three-division force caught the Army of the Republic of Vietnam (ARVN) and their American allies unprepared. The PAVN force struck the defensive pos ...

Cantilever Bridges
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers). For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, ..., or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework. Origins Civil engineer, Engineers in the 19th century understood that a bridge that was continuous across multiple supports would dis ...

Bridges Completed In 1903
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Hong River
The Red River, also known as the Hong River (; vi, Sông Hồng; Chữ Nôm: 瀧紅; Chữ Hán: 紅河), the ' and ' (lit. "Mother River") in Vietnamese, and the (, ' Nguyên Giang) in Chinese, is a -long river that flows from Yunnan in Southwest China through northern Vietnam to the Gulf of Tonkin. According to C. Michael Hogan, the associated Red River Fault was instrumental in forming the entire South China Sea at least as early as 37 million years before present. The name red and southern position in China are associated in traditional cardinal directions. Geography The Red River begins in China's Yunnan province in the mountains south of Dali. Main headstreams Leqiu River, Xi River and Juli River confluence at Nanjian where they form the Lishe River. The Lishe River meets with another headstream, the Yijie River at Hongtupo, Chuxiong Prefecture. It flows generally southeastward, passing through Yi and Dai ethnic minority areas before leaving ...

Nhật Tân Bridge
The Nhật Tân Bridge (or ''Vietnam–Japan Friendship Bridge'') is a cable-stayed bridge crossing the Red River in Hanoi, inaugurated on 4 January 2015. It forms part of a new six-lane highway linking Hanoi and Noi Bai International Airport. The project is funded by a Japan International Cooperation Agency ODA loan. Nhat Tan Bridge has a total length of , including a bridge, with cable-stayed bridge with five spans crossing the Red River. The bridge is wide, divided into four lanes for motorized vehicles, two lanes for buses, two lanes for mixed vehicles and pedestrian paths. Each span has 11 pairs of cables. Nhat Tan Bridge was designed and built to become a new icon of the capital, its five towers symbolizing the five ancient gates of Hanoi. In the summer of 2017, Hanoi partnered with the Dutch company Philips Koninklijke Philips N.V.

Laser-guided Bomb
A laser-guided bomb (LGB) is a guided bomb that uses semi-active laser guidance to strike a designated target with greater accuracy than an unguided bomb. First developed by the United States during the Vietnam War, laser-guided bombs quickly proved their value in precision strikes of difficult point targets. These weapons use on-board electronics to track targets that are designated by laser, typically in the infrared spectrum, and adjust their glide path to accurately strike the target. Since the weapon is tracking a light signature, not the object itself, the target must be illuminated from a separate source, either by ground forces, by a pod on the attacking aircraft, or by a separate support aircraft. Data from the 28,000 laser guided bombs dropped in Vietnam showed that laser-guided bombs achieved direct hits nearly 50% of the time, despite the laser having to be aimed out the side window of the back seat of another aircraft in flight. Unguided bombs had an accuracy rate o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
