2006 North Korean Missile Test
Two rounds of North Korean missile tests were conducted on July 5, 2006. The Democratic People's Republic of Korea (DPRK or North Korea) reportedly fired at least seven separate missiles. These included one long-range Taepodong-2 missile and short-range Scud derived missiles including the enlarged Nodong missile. The Taepodong-2 was estimated by United States intelligence agencies as having a potential range reaching as far as Alaska, although this missile failed after about 42 seconds of flight.. Accessed July 31, 2009.ArchivedAugust 5, 2009. North Korea made its first public acknowledgement of the tests on July 6, through its foreign ministry, describing them as "successful" and part of "regular military drills to strengthen self-defense", insisting that it had the legal right to do so. The country warned of "stronger physical actions" if it were put under pressure by the international community. On July 8, CNN reported that the U.S. had deployed the USS ''Mustin'', a guided ...

Unha-3
The Unha or Eunha ( ko, 은하, 銀河, "Galaxy") is a North Korean expendable carrier rocket, which partially utilizes the same delivery system as the Taepodong-2 orbital launch system. History North Korea's first orbital space launch attempt occurred on August 31, 1998, and was unsuccessful. This launch attempt was performed by a Paektusan-1 rocket, which used a solid motor third stage, a Scud-missile-based second stage, and a Nodong-1 based first stage. Nodong-1 was a North Korean-developed stage thought to be a scale-up of the old Soviet Scud missile. The Paektusan-1 stood tall, was in diameter, and weighed about 21 tonnes. Vehicle description The Unha's first stage consists of four clustered Nodong motors, which themselves are enlarged Scud motors. The second stage was initially thought to be based on the SS-N-6, although it, too, is now believed to be based on Scud technology. The third and last stage might be identical to the Iranian Safir's second stage which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liquid-propellant Rocket
A liquid-propellant rocket or liquid rocket utilizes a rocket engine that uses liquid rocket propellant, liquid propellants. Liquids are desirable because they have a reasonably high density and high Specific impulse, specific impulse (''I''sp). This allows the volume of the propellant tanks to be relatively low. It is also possible to use lightweight centrifugal turbopumps to pump the rocket propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks that do not need to resist the high pressures needed to store significant amounts of gasses, resulting in a low mass ratio for the rocket. An inert gas stored in a tank at a high pressure is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber. These engines may have a higher mass ratio, but are usually more reliable, and are therefore used widely in satellites for orbit ...

Kwangmyŏngsŏng-4
Kwangmyongsong-4 () or KMS-4 is a reconnaissance satellite launched by North Korea on 7 February 2016. The launch happened after North Korea conducted a nuclear test on 6 January and as the United Nations Security Council was deciding on sanctions to be placed on the country following the nuclear test. The launch was also timed to celebrate the 74th birthday of the late leader Kim Jong-il on February 16. Pre-launch On 2 February 2016, North Korea sent a notification to the International Maritime Organization stating that the country was going to launch a Kwangmyongsong earth observation satellite with a launch window of 8–25 February between 22:30 UTC and 03:30 UTC given. The notification also included the drop zones for the first stage, the payload fairing and the second stage of the rocket, which was similar to the areas designated for the launch of Kwangmyongsong-3 Unit 2. On 6 February 2016, North Korea sent another notification to the International Maritime Organiza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taepodong-1
Taepodong-1 ( ko, 대포동-1) was a three-stage technology demonstrator developed by North Korea, a development step toward an intermediate-range ballistic missile. The missile was derived originally from the Scud rocket and was tested once in 1998 as a space launch vehicle. As a space launch vehicle, it was sometimes called the Paektu Mountain, Paektusan 1. History On August 31, 1998, North Korea announced that they had used this rocket to launch their first satellite Kwangmyŏngsŏng-1 from a pad on the Musudan-ri peninsula. However, the satellite failed to achieve orbit; outside observers conjecture that the additional third stage either failed to fire or malfunctioned. This is contrary to official statements of the North Korean state media, which stated that the satellite achieved orbit about 5 minutes after launch. On this single launch, the main two-stage booster flew for 1,646 km without any significant problems. The rocket was launched eastward, passing over Jap ...

Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital flight. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight. Unlike cruise missiles, which are restricted to the atmosphere, it is advantageous for ballistic missiles to avoid the denser parts of the atmosphere and they may travel above the atmosphere into outer space. History The earliest form of ballistic missile dates from the 13th century with its use derived from the history of rockets. In the 14th century, the Ming Chinese navy used an early form of a ballistic missile weapon called the Huolongchushui in naval battles against enemy ships.Needham, Volume 5, Part 7, ...

Scud
A Scud missile is one of a series of tactical ballistic missiles developed by the Soviet Union during the Cold War. It was exported widely to both Second World, Second and Third World, Third World countries. The term comes from the NATO reporting name attached to the missile by Western intelligence agencies. The Russian names for the missile are the R-11 (the first version), and the R-17 (later R-300) Elbrus (later developments). The name Scud has been widely used to refer to these missiles and the wide variety of derivative variants developed in other countries based on the Soviet design. Scud missiles have been used in combat since the 1970s, mostly in wars in the Middle East. They became familiar to the Western public during the 1991 Persian Gulf War, when Ba'athist Iraq, Iraq fired dozens at Israel and Saudi Arabia. In Russian service it is being replaced by the 9K720 Iskander. Development The first use of the term ''Scud'' was in the NATO name SS-1b Scud-A, applied to the ...

Military Of North Korea
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kwangmyŏngsŏng-3 Unit 2
Kwangmyŏngsŏng-3 Unit 2 or Gwangmyeongseong-3 ho 2-hogi (; English: Bright Star-3 Unit 2 or Lodestar-3 Unit 2) is the first satellite successfully launched from North Korea, an Earth observation spacecraft that was launched on 12 December 2012, 00:49 UTC, in order to replace the original Kwangmyŏngsŏng-3, which failed to reach orbit on 13 April 2012. The United Nations Security Council condemned the satellite launch, regarding it as a violation of the ban on North Korean ballistic missile tests, as the rocket technology is the same. The launch came during the period when the DPRK was commemorating the first anniversary of the death of former leader Kim Jong-il and just before the first South Korean domestic launch of a satellite and the South Korean presidential election on 19 December 2012. The successful launch makes the DPRK the tenth space power capable of putting satellites in orbit using its own launch vehicles. North Korea declared the launch successful, and the Sou ...

Tonghae Satellite Launching Ground
The Tonghae Satellite Launching Ground, also known as Musudan-ri (), is a rocket launching site in North Korea. Location It lies in southern Hwadae County, North Hamgyong Province, near Musu Dan, the cape marking the northern end of the East Korea Bay. The area was formerly known as Taep'o-dong (대포동) during the period when Korea was occupied by Japan, and the Taepodong rockets take their name from this. This single loose-surface road is susceptible to seasonal flooding. The site is 45 km northeast of port city of Kimchaek and 45 kilometers (28 miles) from the town of Kilju (길주읍). There is a small wharf located at the fishing village of Tongha-dong but can only accommodate vessels smaller than 40 meters in length. History By the early 80s, North Korea needed a flight-test facility for its program to reverse-engineer and produce copies of the Scud-B which it acquired from the Soviet Union in the late 60s. Previously, North Korea used a facility at Hwajin-ri (華 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hwasong-6
The Hwasong-6 () is a North Korean tactical ballistic missile. It is derived from the Hwasong-5, itself a derivative of the Soviet R-17 Elbrus. It carries the NATO reporting name Scud. History Work on an extended-range version of the Hwasong-5 began in 1988, and with only relatively minor modifications, a new type was produced from 1989, designated Hwasong-6 ("Scud Mod. C" or "Scud-C"). It was first tested in June 1990, and entered full-scale production the same year, or in 1991. It was superseded by the Rodong-1. To increase range over its predecessor, the Hwasong-6 has its payload decreased to and the length of the rocket body extended to increase the propellant by 25%; accuracy is 700–1,000 meters circular error probability (CEP). Such range is sufficient to strike targets as far away as western Japan. Its dimensions are identical to the original Hwasong-5. Due to difficulties in procuring MAZ-543 TELs, mobile launchers were produced in North Korea. By 1999, North Korea wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
