Karakurt-class Corvette
The Karakurt class, Russian designation Project 22800 ''Karakurt'' (russian: Каракурт, , Latrodectus tredecimguttatus European Black Widow), is a new class of Russian corvettes (small missile ships in Russian classification) which have been entering service with the Russian Navy since 2018. The class is intended as a more seaworthy, blue-water complement to the Buyan-M class corvettes, designed for the littoral zone and which serve in Russia's Caspian Flotilla, Baltic Fleet and Black Sea Fleet. The ships are designed to be armed with Kalibr or Oniks anti-ship cruise missiles and have an endurance of 15 days. They are also to be a cheap alternative for larger frigates, for which construction was delayed due to the suspended military cooperation with Ukraine, and because of Russia's intention to continue the modernization of its navy until all necessary tasks for construction of larger vessels domestically are solved. Nevertheless, delays in the supply of domestica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pella Shipyard
Pella ( el, Πέλλα) is an ancient city located in Central Macedonia, Greece. It is best-known for serving as the capital city of the ancient Greek kingdom of Macedon, and was the birthplace of Alexander the Great. On site of the ancient city is the Archaeological Museum of Pella. Etymology The name is probably derived from the word ''pella'', ( grc, πέλλα), "stone" which seems to appear in some other toponyms in Greece like Pellene.S.Solders ''Der unsprüngliche Apollon'' AfRw.

Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matrix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P-800 Oniks
The P-800 Oniks (russian: П-800 Оникс; en, Onyx), also known in export markets as Yakhont (russian: Яхонт; en, ruby), is a Soviet / Russian supersonic anti-ship cruise missile developed by NPO Mashinostroyeniya as a ramjet version of P-80 Zubr. Its GRAU designation is 3M55, the air launched Kh-61 variant also exists. The missile has the NATO codename SS-N-26 " Strobile". Development officially started in 1983, and in the 1990s the anti-ship missile was tested on the Project 1234.7 ship. In 2002 the missile passed the whole range of trials and was commissioned. It is reportedly a replacement for the P-270 Moskit, and possibly also of the P-700 Granit. Description The missile is carried in flight by aerodynamic lift. The solid-propellant booster is located in the ramjet's combustion chamber and is ejected by the airflow after it has burned out.

3M-54 Kalibr
The 3M-54 Kalibr, (Калибр, caliber), also referred to it as 3M54-1 Kalibr, 3M14 Biryuza (Бирюза, turquoise), (NATO reporting name SS-N-27 Sizzler and SS-N-30A) is a family of Russian cruise missiles developed by the Novator Design Bureau (OKB-8). There are ship-launched, submarine-launched and air-launched versions of the missile, and variants for anti-ship, anti-submarine and land attack use. Some versions have a second propulsion stage that initiates a supersonic sprint in the terminal approach to the target, reducing the time that target's defense systems have to react, while subsonic versions have greater range than the supersonic variants. The missile can carry a warhead weighing up to of explosive or a thermonuclear warhead. Design The missile is a modular system with five versions: two anti-shipping types, one for land attack and two anti-submarine types. The missile is designed to share common parts between the surface and submarine-launched variants but ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Launching System
A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of ''cells'', which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up far enough to clear the cell and the ship, then turns on to the desired course. A VLS allows surface combatants to have a greater number of weapons ready for firing at any given time compared to older launching systems such as the Mark 13 single-arm and Mark 26 twin-arm launchers, which were fed from behind by a ...

Hermes (missile)
Hermes (russian: Гермес) is a family of modularly designed guided missiles developed in Russia by the KBP Instrument Design Bureau. The Hermes missile can be used from air, ground or naval launchers. Development Development of the Hermes by the KBP Instrument Design Bureau started in the 1990s. The missile bears a striking resemblance to the Pantsir missile system#Missiles, 57E6 used by the Pantsir missile system, and it is probably a derivative of this model. The Hermes-A variant was trialed in 2003. The series production of the Hermes was meant to start in 2011-2012, but this did not happen, as the development process was stopped for several years. In 2016, it was announced that the Hermes missile would be tested in live conditions in Syria. However, nothing indicates that this actually happened. But in the late 2010s, a series of announcements signaled a renewed interest in the missile, following experience from the Russian military intervention in the Syrian civil war ...

AK-176
The AK-176 is a Soviet naval gun mounted in an enclosed turret, that may be used against sea, coastal, and aerial targets, including low flying anti-ship missiles. The system is designed to arm small displacement ships and comprises the Gun Mount with a MR-123-02/76 Fire Control Radar System. It has high survivability owing to autonomous use of the gun mount controlled from the optical sight in the absence of control from the radar system, as well as a capability for fire even if power supply is lost. Design The gun is fed by 152 ready to fire rounds and has selectable rates of fire of 30, 60 and 120 rounds per minute. The 120 r.p.m. rate is achieved by firing a burst of 75, but afterwards the gun has to cool off for 30 minutes. The AK-176 is effective against missiles, being able to shoot down AT-2 Swatter (simulating a Harpoon anti-ship missile), taking an average of 25 rounds per kill. In the late 1980s an upgraded version the AK-176M, with a new fire control system MR-12 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms) , bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifling , rifled barrel, the distance is measured between opposing Rifling#C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite Communication
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satelli ...
