Pukguksong-3
The Pukguksong-3 (; KN-26 under the U.S. naming convention) is a North Korean two-stage, submarine-launched ballistic missile, likely based on the same motor that powers the Pukkuksong-2. The missile had its first successful flight test on 2 October 2019, although it had been featured in parades in 2017. Compared to older missiles, the Pukguksong-3 likely represents an incremental step forward in SLBM development, possibly towards an eventual, standardised missile. Design The Pukguksong-3 is a further development from the Pukguksong-2, sharing the same 1.4-metre diameter. The missiles were first shown on the 15 April, 2017 parade with an appearance like that of the Pukkuksong-1, Pukguksong-1, but larger, and painted with an uninterrupted black stripe at the nose. The paraded missiles had a skirt with grid fins. More was shown in 22 August, when images of filament wound casing were shown with a larger diameter of 1.4 meters, along with the official name of the missile, on a displ ...

Pukkuksong-1
The Pukguksong-1 or Pukkŭksŏng-1, Bukgeukseong-1 (Hangul: 북극성1호, Hanja: 北極星1号, literally Polaris-1), alternatively KN-11 in intelligence communities outside North Korea, is a North Korean, two-stage submarine-launched ballistic missile (SLBM) that was successfully flight tested on 24 August 2016. Pukguksong-1 is officially recognized by North Korea, South Korea and the United States as a missile that went through a complete, successful test on 24 August 2016. North Korea has never announced the actual operational range and payload, as this technical information is probably considered classified. Most countries do this: e.g., the United States considers the exact operational range of its current SLBM, UGM-133 Trident II, as classified information as well.DEPARTMENT OF DE ...

Submarine-launched Ballistic Missiles
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles. Modern submarine-launched ballistic missiles are closely related to intercontinental ballistic missiles (ICBMs), with ranges of over , and in many cases SLBMs and ICBMs may be part of the same family of weapons. History Origins The first practical design of a submarine-based launch platform was developed by the Germans near the end of World War II involving a launch tube which contained a V-2 ballistic missile variant and was towed behind a submarine, known by the code-name ''Prüfstand XII''. The war ended before it could be tested, but the engineers who had worked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Korea
North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korea, Korean Peninsula and shares borders with China and Russia to the north, at the Yalu River, Yalu (Amnok) and Tumen River, Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone. North Korea's border with South Korea is a disputed border as both countries claim the entirety of the Korean Peninsula. The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like South Korea, its southern counterpart, claims to be the legitimate government of the entire peninsula and List of islands of North Korea, adjacent islands. Pyongyang is the capital and largest city. In 1910, Korean Empire, Korea was Korea under Japanese rule, annexed by the Empire of Japan. In 1945, after the Surrender of Japan, Japanese surrender at the End of World War II in Asia, end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filament Winding
Filament winding is a fabrication technique mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks). This process involves winding filaments under tension over a rotating mandrel. The mandrel rotates around the spindle (Axis 1 or X: Spindle) while a delivery eye on a carriage (Axis 2 or Y: Horizontal) traverses horizontally in line with the axis of the rotating mandrel, laying down fibers in the desired pattern or angle to the rotational axis. The most common filaments are glass or carbon and are impregnated with resin by passing through a bath as they are wound onto the mandrel. Once the mandrel is completely covered to the desired thickness, the resin is cured. Depending on the resin system and its cure characteristics, often the mandrel is autoclaved or heated in an oven or rotated under radiant heaters until the part is cured. Once the resin has cured, the mandrel is removed or extracted, leaving the hollow final product. For some prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

UGM-73 Poseidon
The UGM-73 Poseidon missile was the second US Navy nuclear-armed submarine-launched ballistic missile (SLBM) system, powered by a two-stage solid-fuel rocket. It succeeded the UGM-27 Polaris beginning in 1972, bringing major advances in warheads and accuracy. It was followed by Trident I in 1979, and Trident II in 1990. Development A development study for a longer range version of the Polaris missile—achieved by enlarging it to the maximum possible size allowed by existing launch tubes—started in 1963. Tests had already shown that Polaris missiles could be operated without problems in launch tubes that had their fiberglass liners and locating rings removed. The project was given the title Polaris B3 in November, but the missile was eventually named Poseidon C3 to emphasize the technical advances over its predecessor. The C3 was the only version of the missile produced, and it was also given the designation UGM-73A. Slightly longer and considerably wider and heavier than Po ...

Jane's Information Group
Jane's Information Group, now styled Janes, is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane. History Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems. Based in Greater London for most of its existence, the group was owned by the Thomson Corporation, The Woodbridge Company, then IHS Markit, before being acquired by Montagu Private Equity in 2019.
