Scout Bomber
A scout plane is type of surveillance aircraft, usually of single-engined, two or three seats, shipborne type, and used for the purpose of discovering an enemy position and directing artillery. Therefore, a scout plane is essentially a small naval aircraft, as distinguished from a tactical ground observation aircraft, a strategic reconnaissance "spyplane", or a large patrol flying boat. Scout planes first made their appearances during World War I. Major naval powers, keen on developing the new medium of aerial warfare, converted a number of vessels as seaplane tenders for scouting purpose. Similarly, battleships began to mount short flight decks on top of gun turrets, enabling small fighter-type aircraft to take-off from them; these single-seater "scouts", having no floats to land on and having no landing decks to return to, either had to find dry land for landing, or else had to ditch onto the sea. After World War I, a more satisfactory (although still clumsy) solution had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surveillance Aircraft
A surveillance aircraft is an aircraft used for surveillance. They are operated by military forces and other government agencies in roles such as intelligence gathering, battlefield surveillance, airspace surveillance, reconnaissance, observation (e.g. artillery spotting), border patrol and fishery protection. This article concentrates on aircraft used in those roles, rather than for traffic monitoring, law enforcement and similar activities. Surveillance aircraft usually carry no armament, or only limited defensive armament. They do not always require high-performance capability or stealth characteristics, and may be modified civilian aircraft. Surveillance aircraft have also included moored balloons (e.g. TARS) and unmanned aerial vehicles (UAVs). Definitions The terms “surveillance” and “reconnaissance” have sometimes been used interchangeably, but, in the military context, a distinction can be drawn between surveillance, which monitors a changing situation i ...

Otomat
The Otomat is an anti-ship and coastal defence missile developed by the Italian company Oto Melara jointly with Matra and now made by MBDA. The name comes, for the first versions, from the name of the two builders ("Oto Melara" and "Matra") and, for the later versions, Teseo, from the Italian word for Theseus. The MILAS variant is an anti-submarine missile. In its latest version Mk/2E purchased by the Italian Navy is a medium range anti-ship missile and a ground attack missile. Origins The Otomat missile program started in 1967, the same year in which the Israeli destroyer ''Eilat'' was sunk by three Soviet-made P-15 Termit anti-ship missiles. This event raised awareness about the effectiveness of such weapons and prompted the development of similar systems in Western countries, such as the Harpoon in the United States. However, it is unknown whether the Otomat program started before or after the Eilat event. The Otomat program was undertaken by the Italian Oto Melara corpor ...

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 . A variant of the HS 293 had a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Helicopter
A military helicopter is a helicopter that is either specifically built or converted for use by military forces. A military helicopter's mission is a function of its design or conversion. The most common use of military helicopters is transport of troops, but transport helicopters can be modified or converted to perform other missions such as combat search and rescue (CSAR), medical evacuation (MEDEVAC), airborne command post, or even armed with weapons for attacking ground targets. Specialized military helicopters are intended to conduct specific missions. Examples of specialized military helicopters are attack helicopters, observation helicopters and anti-submarine warfare helicopters. Types and roles Military helicopters play an integral part in the sea, land and air operations of modern militaries. Generally manufacturers will develop airframes in different weight/size classes which can be adapted to different roles through the installation of mission specific equipmen ...

Submarine Aircraft Carrier
A submarine aircraft carrier is a submarine equipped with aircraft for observation or attack missions. These submarines saw their most extensive use during World War II, although their operational significance remained rather small. The most famous of them were the Japanese s and the , although small numbers of similar craft were built for other nations' navies as well. Most operational submarine aircraft carriers, with the exception of the ''I-400'' and AM classes, used their aircraft for reconnaissance and observation. This is in contrast to the typical surface aircraft carrier, whose main function is serving as a base for offensive aircraft. Early history (World War I) Germany was the first nation to experiment with submarine aircraft carriers, initiated by the Imperial German Naval Air Service commander Oberleutnant zur See Friedrich von Arnauld de la Perière who commanded a unit of two Friedrichshafen FF.29 reconnaissance seaplanes in Zeebrugge. One of the first U-b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi F1M
The Mitsubishi F1M ( Allied reporting name "Pete") was a Japanese reconnaissance floatplane of World War II. It was the last biplane type of the Imperial Japanese Navy, with 944 built between 1936 and 1944. The Navy designation was "Type Zero Observation Seaplane" (零式水上観測機). Design and development In 1934, the Imperial Japanese Navy issued a specification to Mitsubishi, Aichi and Kawanishi for a replacement for its Nakajima E8N floatplanes, which were used for short-ranged reconnaissance and observation missions from the Navy's warships.Francillon 1970, p. 358. Mitsubishi's design, the Ka-17, given the short system designation F1M1 by the Japanese Navy, was a small all-metal biplane powered by a single Nakajima Hikari 1 radial engine rated at , the same engine as used by Aichi's competing F1A. It had elliptical wings and great care had been taken to reduce drag, with the number of interplane struts and bracing wires minimised. The first of four F1M1s flew in June ...

Aichi E13A
The Aichi E13A ( Allied reporting name: "Jake") was a long-range reconnaissance seaplane used by the Imperial Japanese Navy (IJN) from 1941 to 1945. Numerically the most important floatplane of the IJN, it could carry a crew of three and a bombload of 250 kg (550 lb). The Navy designation was "Navy Type Zero Reconnaissance Seaplane" (零式水上偵察機). Operational history In China, it operated from seaplane tenders and cruisers. Later, it was used as a scout for the Attack on Pearl Harbor, and was encountered in combat by the United States Navy during the Battles of Coral Sea and Midway. It was in service throughout the conflict, for coastal patrols, strikes against navigation, liaison, officer transports, castaway rescues, and other missions, along with some ''kamikaze'' missions in the last days of war. One Aichi E13A was operated by Nazi Germany alongside two Arado Ar 196s out of the base at Penang. The three aircraft formed the East Asia Naval Special Ser ...

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indirect Fire
Indirect fire is aiming and firing a projectile without relying on a direct line of sight between the gun and its target, as in the case of direct fire. Aiming is performed by calculating azimuth and inclination, and may include correcting aim by observing the fall of shot and calculating new angles. Description There are two dimensions in aiming a weapon: * In the horizontal plane (azimuth); and * In the vertical plane (elevation), which is governed by the distance (range) to the target and the energy of the propelling charge. The projectile trajectory is affected by atmospheric conditions, the velocity of the projectile, the difference in altitude between the firer and the target, and other factors. Direct fire sights may include mechanisms to compensate for some of these. Handguns and rifles, machine guns, anti-tank guns, tank main guns, many types of unguided rockets (although missiles, mortars, howitzers, rocket artillery, multiple rocket launchers, and artillery ...

Vought OS2U Kingfisher
The Vought OS2U Kingfisher is an American catapult-launched observation floatplane. It was a compact mid-wing monoplane, with a large central float and small stabilizing floats. Performance was modest because of its low-powered engine. The OS2U could also operate on fixed, wheeled, taildragger landing gear. The OS2U was the main shipboard observation seaplane used by the United States Navy during World War II, and 1,519 of the aircraft were built. It served on battleships and cruisers of the US Navy, with the United States Marine Corps in Marine Scouting Squadron Three (VMS-3), with the United States Coast Guard at coastal air stations, at sea with the Fleet Air Arm of the Royal Navy, and with the Soviet Navy. The Royal Australian Air Force also operated a few Kingfishers from shore bases. The Naval Aircraft Factory OS2N was the designation of the OS2U-3 aircraft built by the Naval Aircraft Factory in Philadelphia, Pennsylvania. The OS2U first flew on 1 March 1938. Design an ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
