Defensive Aid Subsystems
A defensive aide suite (DAS) is a military aircraft system which defends it from attack by surface-to-air missiles, air-to-air missiles and guided anti-aircraft artillery. A DAS typically comprises chaff, flares, and electronic countermeasures combined with radar warning receivers to detect threats. On some modern aircraft (Lockheed Martin F-35 Lightning II), the entire system is integrated and computer-controlled, allowing an aircraft to autonomously detect, classify and act in an optimal manner against a potential threat to its safety. A Defensive Aid Suite (DAS) system can be used in conjunction with the NGVA architecture in combat vehicles as well.Kyriakos Houliotis, Panagiotis Oikonomidis, Periklis Charchalakis, Elias Stipidis.

Iron Fist (countermeasure)
Iron Fist ( he, חץ דורבן, ''Hetz Dorban'', lit. "Porcupine Arrow") is a hard-kill active protection system (APS) designed by Israel Military Industries (IMI), with a modular design allowing adaptation to a range of platforms ranging from light utility vehicles to heavy armoured fighting vehicles. The concept was revealed by IMI in 2006 and was expected to enter Israel Defense Forces tests by mid-2007. The system has been successfully tested against a wide variety of threats including rocket-propelled grenades, anti-tank guided missiles and tank-fired high-explosive anti-tank (HEAT) ammunition and kinetic energy penetrators. It senses incoming threats via a fixed active electronically scanned array radar sensor developed by RADA Electronic Industries and an optional passive infrared detector developed by Elbit's Elisra. When a threat is imminent, an explosive projectile interceptor is launched towards it. The interceptor explodes very near the threat, destroying or ...

BM Oplot
The T-84 is a Ukrainian main battle tank (MBT), based on the Soviet T-80 MBT introduced in 1976, specifically the diesel engine version: T-80UD. The T-84 was first built in 1994 and entered service in the Ukrainian Armed Forces in 1999. Its high-performance opposed-piston engine makes it a fast tank, comparable to other modern MBTs with a power-to-weight ratio of about 26 horsepower per tonne (19 kW/t). The T-84 Oplot is an advanced version incorporating an armoured ammunition compartment in a new turret bustle. Ten of these entered Ukrainian service in 2001. The T-84-120 Yatagan is a prototype model intended for export, mounting a 120 mm gun able to fire standard NATO ammunition and guided missiles. Development history After the adoption of the T-80 tank, the Soviets began improving its design. The disadvantages of the gas-turbine engine were readily apparent, and so several design projects were initiated to adopt a diesel alternative. Development of the T-80UD L ...

Zaslon Active Protection System
Zaslin active protection system (; is often incorrectly named with Russian word Zaslon) is being developed by Microtek in cooperation with other military design organizations. The system is designed to protect stationary or mobile targets from anti-tank weapons with flat or diving trajectories using various types of guidance systems and warheads. Unlike existing Russian-designed active protection systems Drozd and Arena, Zaslin can be deployed alongside reactive armour placed in the turret area, which is vulnerable to anti-tank projectiles traveling at speeds up to Design The Zaslin system consists of a radar-based detection module, a guidance module and static counter-measure modules. Each counter-measure module packs two explosive charges, which are ejected toward the target before detonating and forming a dense fragmentation ring that destroys incoming projectiles on impact. Modules can point forward, sideways or vertically, to protect from attacks from above. The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arena Active Protection System
Arena (russian: Арена) is an active protection system (APS) developed at Russia's Kolomna-based Engineering Design Bureau for the purpose of protecting armoured fighting vehicles from destruction by light anti-tank weapons, anti-tank guided missiles (ATGM), and missiles with top attack warheads. It uses a Doppler radar to detect incoming warheads. Upon detection, a defensive rocket is fired that detonates near the inbound threat, destroying it before it hits the vehicle. ''Arena'' is the successor to ''Drozd'', a Soviet active protection system from the late 1970s, which was installed on several T-55s during the Soviet–Afghan War. The system improved the vehicle's survivability rate, increasing it by up to 80%. ''Drozd'' was followed by ''Shtora'' in the late 1980s, which used an electro-optical dazzlers or expendable so (smoke/IR smoke) to confuse the seeker head or defeat the user. In late 1994 the Russian Army deployed many armoured fighting vehicles to Chechnya, where th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drozd
Drozd ( rus, Дрозд, , ˈdrost, Ru-дрозд.ogg, thrush) is an active protection system (APS) developed in the Soviet Union, designed for increasing tanks' protection against anti-tank missiles and RPGs. It is considered the world's first operational active protection system, created in 1977–78 by A. Shipunov's KBP design bureau as ''Kompleks 1030M-01''. Its chief designer, Vasily Bakalov, was awarded the Lenin Prize for his work on its development. Drozd uses 24.5 GHz Doppler radar to detect incoming rounds travelling between 70 and 700 m/s (to avoid engaging small arms or other faster projectiles). Its computer determines when to fire a 107 mm projectile. When the incoming round is at 7 m range, the Drozd fragmentation warhead detonates, spreading 3-gram slugs to destroy the incoming round. The Drozd system was relatively complex, requiring a radar array and two launch tubes on each side of the tank turret, and a large electronics package on the ...

Active Protection System
An active protection system is a system designed to actively prevent certain anti-tank weapons from destroying a vehicle. Countermeasures that either conceal the vehicle from, or disrupt the guidance of an incoming guided missile threat are designated soft-kill active protection measures. Countermeasures that physically strike an incoming threat to damage or destroy it and thereby limit its ability to penetrate armor are designated hard-kill active protection measures. Soft-kill measures Soft-kill measures are designed to defeat guided weapons either by concealing the protected vehicle from them (for example, with a smoke screen) or by disrupting their guidance with radiation (for example, with a dazzler). Some systems use laser dazzlers to blind the operator or sensors of semi-automatic command to line of sight (SACLOS) anti-tank guided missiles (ATGMs), such as the JD-3 of the Type 99 tank. Others use powerful infrared emitters to mask the IR tracking flare present on many SACL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Martin F-35 Lightning II
The Lockheed Martin F-35 Lightning II is an American family of single-seat, single-engine, all-weather stealth multirole combat aircraft that is intended to perform both air superiority and strike missions. It is also able to provide electronic warfare and intelligence, surveillance, and reconnaissance capabilities. Lockheed Martin is the prime F-35 contractor, with principal partners Northrop Grumman and BAE Systems. The aircraft has three main variants: the conventional takeoff and landing (CTOL) F-35A, the short take-off and vertical-landing (STOVL) F-35B, and the carrier-based (CV/ CATOBAR) F-35C. The aircraft descends from the Lockheed Martin X-35, which in 2001 beat the Boeing X-32 to win the Joint Strike Fighter (JSF) program. Its development is principally funded by the United States, with additional funding from program partner countries from NATO and close U.S. allies, including the United Kingdom, Australia, Canada, Italy, Norway, Denmark, the Netherland ...

Radar Warning Receiver
Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat. RWR systems can be installed in all kind of airborne, sea-based, and ground-based assets such as aircraft, ships, automobiles, military bases. This article is focused mainly on airborne military RWR systems; for commercial police speed detection radar RWR systems, see radar detector. Depending on the market the RWR system is designed for, it can be as simple as detecting the presence of energy in a specific radar band, such as the frequencies of known surface-to-air missile systems. Modern RWR systems are often capable of classifying the source of the radar by the signal's strength, phase and signal details. The information about the signal's strength and waveform can t ...
