Polyphem (missile)
The Polyphem was a proposed light-weight fibre-optic wire-guided surface-to-surface missile with a range of 60 km. It uses a sealed round, a solid propellant booster rocket to launch the missile out of its canister to an initial height, so that the wings and control surfaces can unfold, and a more fuel economic turbojet cruise engine kicks in to propel the missile. The missile can be programmed to follow a preset course, using GPS or inertial guidance. An infrared seeker can be used to automatically pick a target and for the terminal guidance phase, but it is also possible to transfer the thermal images back to the launching platform via a 200 MBit/s data link provided by an optical fibre, and manually select the target. The Polyphem program was started in 1994 by Germany, France and Italy. Italy later left the project. A naval version, called Polyphem-S, was initially selected for the Braunschweig class corvette as anti-ship and land-attack missile, but that has been cancel ...

Anti-ship Missile
An anti-ship missile (AShM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea skimming variety, and many use a combination of inertial guidance and active radar homing. A good number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the ''Fritz X'', including the Italian battleship ''Roma'' and the light cruiser .

XM501 Non-Line-of-Sight Launch System
The Non-Line of Sight Launch System (NLOS-LS) was a self-contained missile launcher system that was under development by NETFIRES LLC, a partnership between Lockheed Martin and Raytheon. Each Container Launch Unit (CLU) holds 15 missiles, and a self-locating networked communications system. CLUs can be linked for coordinated launching, with the missiles fired and controlled remotely via autonomous vertical launch. The weapon is roughly 2 metres tall. The program was cancelled early 2011. It was being developed for the United States Navy's Littoral Combat Ship, but has been criticised for performance issues. The Griffin missile has been recommended for use instead. NLOS-LS was to be used primarily on the United States Army's Future Combat Systems before it was canceled. Concept There were to be two types of missile used with NLOS-LS: the Precision Attack Munition (PAM) and the Loitering Attack Munition (LAM). The LAM was originally contracted to Lockheed Martin Missiles an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MGM-157 EFOGM
The Raytheon MGM-157 EFOGM (Enhanced Fiber Optic Guided Missile) was a long-range enhanced fiber optic guided missile developed for the U.S. Army during the 1980s and 1990s to test the use of fiber optics in missiles. The missile was launched vertically and manually controlled by an operator on the ground by use of a television camera mounted on the nose. The signals from the camera were carried via a thin wire that unspooled the further up the missile reached. The weapon was primarily designed for anti-tank use, or against low flying helicopters.

FOG-MPM
FOG-MPM (Fiber Optics Guided Multiple Purpose Missile) is a missile built by the Brazilian company Avibras. Its range is about 60 km. The weight is about 34 kg. Its main use is as an anti-tank, anti-fortification and anti-helicopter missile. FOG-MPM is guided by optical fiber technology. The FOG-MPM is very flexible, can be launched from ground vehicles (Astros II MLRS), ships and helicopters, and is immune to electronic measures. Development Work on the development of FOG-MPM or MAC-MP (Multi Purpose Fiber Optic Guided Missile - Missile Anti-Car Multi-Purpose) was initiated in 1985 by Avibrás and unveiled in 1989. The program is funded by the company itself, with all the components produced in country. In 1989 there were three test launches; in 1992, there were 8. The missile has a length of 1.50 meters and is 18 centimeter in diameter, weighing 33 kg (24 kg initially). It has a range of about 10 km to 20 km, relaxed in later versions. The spe ...

CM-501G
CM501G is a Chinese land attack missile first revealed during the 9th Zhuhai Airshow held in November 2012. Developed by China Aerospace Science and Industry Corporation (CASIC), CM-501G is also available in air and ship launched versions upon customers' requests, but only the land-based version made its public debut at the airshow. International comparisons The CM-501G missile has been said by many Chinese internet sources as the Chinese equivalent of the American NLOS-LS Netfires missile or the Israeli JUMPER missile, but the Chinese missile is much larger than the two western counterparts: in comparison to the 50 to 60 kg range of western missiles, CM-501G weighs around 150 kg, almost three times the weight of Netfires or JUMPER missiles. The >70 km range of the CM-501G is equal to that of the Netfires missile, and is longer than the 50 km range of the JUMPER missile and the warhead of CM-501G is around 40 kg. Guidance options CM-501G also has more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ALAS (missile)
ALAS (Advanced Light Attack System, sr, АЛАС) is a Serbian long-range multipurpose wire guided missile system developed by the private company EdePro and the state-owned Yugoimport SDPR. The ALAS missile system was developed primarily for missions against tanks, armored vehicles, fortifications, command posts, low-flying helicopters, coastal ships, industrial facilities and bridges. It can be deployed by any suitable platform including helicopters, armored vehicles, small ships and infantry. The guidance system is based on video/infrared technology, with the missile connected to the launcher by a fiber-optic cable. The ALAS flies at low altitude and has small radar and infrared (heat) signatures due to using a turbofan motor instead of a turbojet. In recent years, the ALAS platform has found a secondary use as a UAV. Description of system and role The ALAS missile system is intended for two primary missions: * Striking isolated targets from light land vehicles and for an ...

Kilogram
The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'. The kilogram is defined in terms of the second and the metre, both of which are based on fundamental physical constants. This allows a properly equipped metrology laboratory to calibrate a mass measurement instrument such as a Kibble balance as the primary standard to determine an exact kilogram mass. The kilogram was originally defined in 1795 as the mass of one litre of water. The current definition of a kilogram agrees with this original definition to within 30 parts per million. In 1799, the platinum ''Kilogramme des Archives'' replaced it as the standard of mass. In 1889, a cylinder of platinum-iridium, the International Prototype of the Kilogram (IPK), became the standard of the unit of mass for ...

Second
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Odysseus
Odysseus ( ; grc-gre, Ὀδυσσεύς, Ὀδυσεύς, OdysseúsOdyseús, ), also known by the Latin variant Ulysses ( , ; lat, UlyssesUlixes), is a legendary Greek king of Ithaca and the hero of Homer's epic poem the ''Odyssey''. Odysseus also plays a key role in Homer's ''Iliad'' and other works in that same epic cycle. Son of Laërtes and Anticlea, husband of Penelope, and father of Telemachus and Acusilaus, Odysseus is renowned for his intellectual brilliance, guile, and versatility (''polytropos''), and is thus known by the epithet Odysseus the Cunning ( grc-gre, μῆτις, mêtis, cunning intelligence). He is most famous for his ''nostos'', or "homecoming", which took him ten eventful years after the decade-long Trojan War. Name, etymology, and epithets The form ''Odys(s)eus'' is used starting in the epic period and through the classical period, but various other forms are also found. In vase inscriptions, we find the variants ''Oliseus'' (), ''Olyseus'' (), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odyssey
The ''Odyssey'' (; grc, Ὀδύσσεια, Odýsseia, ) is one of two major Ancient Greek literature, ancient Greek Epic poetry, epic poems attributed to Homer. It is one of the oldest extant works of literature still widely read by modern audiences. As with the ''Iliad'', the poem is divided into 24 books. It follows the Greek hero cult, Greek hero Odysseus, king of Homer's Ithaca, Ithaca, and his journey home after the Trojan War. After the war, which lasted ten years, his journey lasted for ten additional years, during which time he encountered many perils and all his crew mates were killed. In his absence, Odysseus was assumed dead, and his wife Penelope and son Telemachus had to contend with a Suitors of Penelope, group of unruly suitors who were competing for Penelope's hand in marriage. The ''Odyssey'' was originally composed in Homeric Greek in around the 8th or 7th century BCE and, by the mid-6th century BCE, had become part of the Greek literary canon. In Classic ...
