Mortier 120mm Rayé Tracté Modèle F1
The MO-120 RT (factory designator) or MO-120-RT is a French heavy mortar. The RT in the designator stands for ''rayé, tracté'', which means rifled, towed. The MO-120-RT is currently used by the French Army (where it is known as RT F1 or Mortier de 120mm Rayé Tracté Modèle F1—"120 mm rifled towed mortar, model F1"), and has also been exported to more than 24 foreign countries or in some cases, produced under licence. It is issued to artillery units, where it complements artillery guns and systems; although infantry units operate it in some countries. A vehicle-mounted and automated mortar system derived from the MO-120 RT, known as the 2R2M is in service with a number of nations. Design The MO-120 RT uses standard NATO rounds with a range of 8,2 km and the PRPA (RAP-Rocket Assisted Projectile) with a range of 13 km. The weapon can be fired either by dropping the round down the tube (after aligning of the rifling bands) resulting in an automatic firing once the ...

2R2M Mortar
The 2R2M (''Rifled Recoiled Mounted Mortar'') is a vehicle-mounted, rifled 120 mm heavy mortar produced by Thales of France. It is derived from the MO-120-RT towed mortar. The 2R2M is in service with 5 nations. The US Marine Corps field-tested a mortar system derived from the 2R2M in the early 2000's under the project names ''Dragon Fire'' and ''Dragon Fire II''. More than just an adaptation of the 2R2M system to the USMC's LAV-25 chassis, this project aimed for the added option to lift the entire weapon assembly, including the semi-automated loading mechanism and the computerised fire control system, out of the carrier vehicle and put it on a carriage to be towed by a tractor vehicle such as a HMMWV. The USMC eventually dropped the Dragon Fire II project and instead opted for the baseline MO-120-RT mortar, which it called the M327 mortar, towed by a M1161 Growler, for their EFSS (''Expeditionary Fire Support System'').

Mortar (weapon)
A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that was simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Ground Self-Defense Force
The Japan Ground Self-Defense Force ( ja, 陸上自衛隊, Rikujō Jieitai), , also referred to as the Japanese Army, is the land warfare branch of the Japan Self-Defense Forces. Created on July 1, 1954, it is the largest of the three service branches. New military guidelines, announced in December 2010, direct the Japan Self-Defense Forces away from their Cold War focus on the Soviet Union to a new focus on China, especially in respect of the dispute over the Senkaku Islands. The JGSDF operates under the command of the chief of the ground staff, based in the city of Ichigaya, Shinjuku, Tokyo. The present chief of staff is General Yoshihide Yoshida.

Semi-active Laser
Laser guidance directs a robotics system to a target position by means of a laser beam. The laser guidance of a robot is accomplished by projecting a laser light, image processing and communication to improve the accuracy of guidance. The key idea is to show goal positions to the robot by laser light projection instead of communicating them numerically. This intuitive interface simplifies directing the robot while the visual feedback improves the positioning accuracy and allows for implicit localization. The guidance system may serve also as a mediator for cooperative multiple robots. Examples of proof-of-concept experiments of directing a robot by a laser pointer are shown on video. Laser guidance spans areas of robotics, computer vision, user interface, video games, communication and smart home technologies. Commercial systems Samsung Electronics Co., Ltd. may have been using this technology in robotic vacuum cleaners since 2014. Google Inc. applied for a pa ...

Reverse Slope Defence
A reverse slope defence is a military tactic where a defending force is positioned on the slope of an elevated terrain feature such as a hill, ridge, or mountain, on the side opposite from the attacking force. This tactic both hinders the attacker's ability to observe the defender's positions and reduces the effectiveness of the attacker's long-range weapons such as tanks and artillery. A defending unit usually does not conduct a reverse-slope defence along its entire front, as positioning troops on the forward slope is necessary to control the region in front of the hill. However, when enemy forces are known to have superior long-range direct-fire or indirect-fire weapons, the majority of the defending force can use the hill to limit enemy observation and reduce the effectiveness of the long-range enemy fire. This tactic may even succeed in deceiving the enemy as to the true location and organisation of the main defensive positions. Typically, a smaller unit is still posted on th ...

Canard (aeronautics)
In aeronautics, a canard is a wing configuration in which a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft or a weapon. The term "canard" may be used to describe the aircraft itself, the wing configuration, or the foreplane.. Canard wings are also extensively used in guided missiles and smart bombs. The term "canard" arose from the appearance of the Santos-Dumont 14-bis of 1906, which was said to be reminiscent of a duck (''canard'' in French) with its neck stretched out in flight. Despite the use of a canard surface on the first powered aeroplane, the Wright Flyer of 1903, canard designs were not built in quantity until the appearance of the Saab Viggen jet fighter in 1967. The aerodynamics of the canard configuration are complex and require careful analysis. Rather than use the conventional tailplane configuration found on most aircraft, an aircraft designer may adopt the canard configuration to reduce the main wing loading, to better ...

CH-53E Super Stallion
The Sikorsky CH-53E Super Stallion is a heavy-lift helicopter operated by the United States military. As the Sikorsky S-80, it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor, and canting the tail rotor 20°. It was built by Sikorsky Aircraft for the United States Marine Corps. The less common MH-53E Sea Dragon fills the United States Navy's need for long-range minesweeping or airborne mine countermeasures missions, and perform heavy-lift duties for the Navy. The Sikorsky CH-53K King Stallion, which has new engines, new composite rotor blades, and a wider aircraft cabin, is set to replace the CH-53E. Development Background The CH-53 was the product of the U.S. Marines' "Heavy Helicopter Experimental" (HH(X)) competition begun in 1962. Sikorsky's S-65 was selected over Boeing Vertol's modified CH-47 Chinook version. The prototype YCH-53A first flew on 14 October 1964.

Growler (jeep)
The M1161 Growler is officially the Internally Transportable Light Strike Vehicle (ITV-LSV) designed specifically for use with the Osprey tiltrotor aircraft. The M1161 and M1163 are the only tactical vehicles certified to fly in the . Fulfilling multiple roles of light utility, light strike and fast attack vehicle, the M1161 Growler is smaller than most international vehicles in the same role. It has taken over duties of the M151 jeep-type variants and replaced the Interim Fast Attack Vehicle (IFAV). A separate US Marine Corps variant, the shorter two-seat M1163 prime mover is combined with the M327 towed 120mm heavy mortar, and also became its ammunition hauler after the M1162 trailer was cancelled. History Development for the Growler began in 1999 by American Growler when the Marine Corps sought a vehicle that could be transported in a Osprey. Though the initial design used elements and parts from the drive train of the M151 which it was intended to replace, the fin ...

MV-22 Osprey
The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed Cruise (aeronautics), cruise performance of a turboprop aircraft. In 1980, the failure of Operation Eagle Claw (during the Iran hostage crisis) underscored that there were military roles for which neither conventional helicopters nor fixed-wing transport aircraft were well-suited. The United States Department of Defense (DoD) initiated a program to develop an innovative transport aircraft with long-range, high-speed, and vertical-takeoff capabilities, and the Joint-service Vertical take-off/landing Experimental (JVX) program officially commenced in 1981. A partnership between Bell Textron, Bell Helicopter and Boeing Rotorcraft Systems, Boeing Helicopters was awarded a development contract in 19 ...
