The Helkir is an anti-helicopter mine developed by the Austrian company Hirtenberger. [1] It uses an IR sensor and an acoustic sensor to detect airborne targets. Once the mine is armed and ready to engage, the acoustic sensor listens for a valid noise input. This enables the IR sensor which is located coaxially to the warhead. When the IR sensor detects a hot signature, the mine blasts off fragments that can penetrate up to 6 mm of armored steel at 50 meters and 2 mm of mild steel at 150 meters. The mine is active for a period of 1 to 120 days, after which it returns to a safe mode.
Helkir, as well as other mines developed by Hirtenberger, like the APM-1 and the APM-2 anti-personnel directional mines (discontinued in 1994), [2] do not appear on the company's current website. [3]
Sonar is a technique that uses sound propagation to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.
The GATOR mine system is a United States military system of air-dropped anti-tank and anti-personnel mines developed in the 1980s to be compatible with existing cluster dispensers. It is used with two dispenser systems—the Navy 230 kg (500 lb) CBU-78/B and the Air Force 450 kg (1,000 lb) CBU-89/B. Additionally the mines are used with the land- and helicopter-based Volcano mine system.
The Sikorsky SH-60/MH-60 Seahawk is a twin turboshaft engine, multi-mission United States Navy helicopter based on the United States Army UH-60 Black Hawk and a member of the Sikorsky S-70 family. The most significant modifications are the folding main rotor blades and a hinged tail to reduce its footprint aboard ships.
A bounding mine is an anti-personnel mine designed to be used in open areas. When it is tripped, a small propelling charge launches the body of the mine 3 to 4 feet into the air, where the main charge detonates and sprays fragmentation at roughly waist height.
Anti-submarine warfare is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades.
The National Engineering & Scientific Commission (NESCOM) is a Pakistani government-funded defense contractor that develops, designs and sells defense hardware, including missile and weapon systems. It was funded and formed by the Government of Pakistan to develop its domestic production of weapon system.
The TM-83 is a Soviet off-route anti-tank mine with a shaped charge, developed in 1983, and first shown publicly in 1993. The mine utilises the Misznay Schardin effect to create an armour-penetrating projectile, and is activated using its infrared and seismic sensors.
The VS-50 is a circular plastic-cased anti-personnel blast mine that entered production in 1985. It was formerly made by the now-defunct Valsella Meccanotecnica SpA, an Italian high-tech defence company specialized in area denial systems. The company also the made the Valmara 69, and was one of the first to implement plastic construction for landmines. The VS-50's design is similar to that of the TS-50 and VS-MK2 mines. It is blast resistant and can be used in a minimum metal configuration. Though unlikely to kill, its explosive charge is quite sufficient to destroy the victim's foot, being capable of penetrating 5 mm of mild steel leaving an 80 mm-diameter hole.
ARGES is an anti-tank off-route mine, developed by an international consortium to meet the needs of the British, French and German armed forces. The system consists of a rocket and launch tube, a tripod and a sensor package.
The 4AHM-100, AHM-200, AHM-200-1, AHM-200-2, PMN-150, and PMN-250 are Bulgarian directional fragmentation mines that can be used with proximity fuzes to function as anti-helicopter mines.
The HAK-1 is a Hungarian plastic encased anti-tank mine. It uses a Misznay Schardin effect warhead combined with an electronic acoustic and magnetic influence fuze. The mine can be programmed for an active life of between three hours and 150 days. Once the acoustic sensor detects a target, the magnetic influence sensor is used to detonate the mine at the optimal point. The warhead is capable of penetrating 45 mm of armour and producing a 130 mm diameter hole.
The MPB is a Polish off-route anti-tank mine. It was developed by BELMA with its partner Military Institute of Engineer Technology. The MPB consists of a metal cylinder filled with explosives, mounted horizontally in an adjustable frame. The mine is intended to be hidden from direct view of the intended target, off to the side of a probable vehicle route, usually a road, to attack the weaker armour on the sides and rear of a vehicle. The mine can be triggered by either a contact fuze or an influence fuze based on infrared and acoustic sensors, and is also fitted with an anti-handling device. When used with the passive infrared fuze, an acoustic sensor detects approaching vehicles and activates the infrared sensor, which triggers the mine at an optimal moment as the target passes. The mine can be programmed to self-destruct after either 1, 10 or 30 days have passed.
A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
Geophysical MASINT is a branch of Measurement and Signature Intelligence (MASINT) that involves phenomena transmitted through the earth and manmade structures including emitted or reflected sounds, pressure waves, vibrations, and magnetic field or ionosphere disturbances.
The MW-1 is a German munitions dispenser similar to the British JP233. It is designed to be carried on the Tornado IDS, although it can be carried on the Lockheed F-104 Starfighter and the McDonnell Douglas F-4 Phantom II. The MW-1 started to be phased out after the German Government ratified the Convention on Cluster Munitions in 2009.
The M6 Mortar is a 60 mm lightweight infantry mortar made by Hirtenberger AG of Austria.
INS Kamorta is the first of four anti-submarine Kamorta-class stealth corvettes which has been built for the Indian Navy.
INS Kadmatt (P29) is the second of four anti-submarine warfare corvettes built for the Indian Navy by the Garden Reach Shipbuilders and Engineers of Kolkata under Project 28. She was inducted into the Eastern Naval Command of the Indian Navy.
The POM-2 is a Soviet scatterable self-liquidating fragmentation anti-personnel mine. It has a mechanical fuze with tension-type target sensors BP-09C.
