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. [1]
Electromagnetic warfare or electronic warfare (EW) is warfare involving the use of the electromagnetic spectrum or directed energy to control the spectrum, attack an enemy, or impede enemy operations. The purpose of electromagnetic warfare is to deny the opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. Electromagnetic warfare can be applied from air, sea, land, or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets.
An anti-ship missile 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 large 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.
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers.
Arena 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 flyover top attack missiles. 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.
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.
Man-portable air-defense systems are portable shoulder-fired surface-to-air missiles. They are guided weapons and are a threat to low-flying aircraft, especially helicopters and also used against low-flying cruise missiles. These short-range missiles can also be fired from vehicles, tripods, weapon platforms, and warships.
An active protection system (APS) is a system designed to actively prevent certain anti-tank weapons from destroying a vehicle.
Trophy is a protection system for military armored vehicles. It is termed an active protection system (APS) and is designed by Rafael Advanced Defense Systems.
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing missiles by confusing the missiles' infrared guidance system so that they miss their target. Heat-seeking missiles were responsible for about 80% of air losses in Operation Desert Storm. The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile.
Civil Aircraft Missile Protection System (CAMPS) is an infrared countermeasure against infrared-homed anti-aircraft missiles, specifically designed to defend civilian aircraft flying under 15,000 feet (4,600 m) against MANPADS.
Flight Guard is an Elta Systems Ltd's brand name for a family of airborne systems for protecting civilian aircraft against man-portable air-defense systems.
The Northrop Grumman Guardian is a passive anti-missile countermeasure system designed specifically to protect commercial airliners from shoulder-launched missiles, using directed infrared countermeasures (DIRCM) technology.
The Combat Aircraft Systems Development & Integration Centre (CASDIC) is a laboratory of the Indian Defence Research and Development Organisation (DRDO). Located in Bangalore, Karnataka, India, It is one of the two DRDO laboratories involved in the research and development of airborne electronic warfare and mission avionics systems.
A missile approach warningsystem (MAW) is part of the avionics package on some military aircraft. A sensor detects attacking missiles. Its automatic warning cues the pilot to make a defensive maneuver and deploy the available countermeasures to disrupt missile tracking.
Quick Kill is an active protection system (APS) designed to destroy incoming anti-tank missiles, rockets, and grenades. The Quick Kill system is designed and produced by Raytheon for the U.S. Army. The Quick Kill system was part of the United States Army's Future Combat Systems.
The AN/ALE-47 Airborne Countermeasures Dispenser System is used to protect military aircraft from incoming radar and infrared homing missiles. It works by dispensing flares or chaff. It is used on a variety of U.S. Air Force, Navy, and Army aircraft, as well as in other militaries.
The AN/AAR-47 Missile Warning System is a Missile Approach Warning system used on slow moving aircraft such as helicopters and military transport aircraft to notify the pilot of threats and to trigger the aircraft's countermeasures systems. Its main users are the U.S. Army, U.S. Marine Corps, Navy and Air Force, but is also operated by other countries. Originally developed by Loral, and later dual-source procured from Loral Infrared & Imaging Systems and Honeywell Electro-Optics Div., both in Lexington, MA, it has been a product of Alliant Techsystems 100 to 300 sets have been manufactured per annum. (ATK) since 2002, now Northrop Grumman.
CIRCM, the Common Infrared Countermeasures program, is a United States Army initiative intended to develop a lightweight, low-cost and modular laser-based infrared protection system for U.S. helicopters and light fixed-wing aircraft. The technology will primarily provide defense against shoulder-fired, heat-seeking missiles, or MANPADS. The program is being developed to replace older suites such as the Advanced Threat Infrared Countermeasures (ATIRCM).
BriteCloud is a self-contained expendable digital radio frequency memory (DRFM) jammer developed by Selex ES to help protect military aircraft. The decoy was launched by Selex ES at a conference held at the Churchill War Rooms, London on 6 November 2013.
The EuroDASS Praetorian DASS is an integral part of Eurofighter Typhoon defensive Aid Sub-System (DASS) providing threat assessment, aircraft protection and support measures in extremely hostile and severe environments. As the DASS is fully integrated, it does not require additional pods that take up weapon stations or would influence the aircraft's aerodynamic performance. The modular nature of the DASS simplifies future upgrades and allows each partner nation or export customer the option to tailor the DASS to their individual needs.
