The AN/ALE-50 towed decoy system is an electronic countermeasure tool designed by Raytheon to protect multiple US military aircraft from air-to-air and surface-to-air radar-guided missiles. [1] The AN/ALE-50 towed decoy system is an anti-missile countermeasures decoy system used on U.S. Air Force, Navy, and Marine Corps aircraft, and by certain non-United States air forces. The system is manufactured by Raytheon Space and Airborne Systems at its facility in Goleta, California. The ALE-50 system consists of a launcher and launch controller installed on the aircraft (usually on a wing pylon), and one or more expendable towed decoys. Each decoy is delivered in a sealed canister and has a ten-year shelf life. [2]
When deployed, the decoy is towed behind the host aircraft, protecting the aircraft and its crew against RF-guided missiles by luring the missile toward the decoy and away from the intended target. In both flight tests and actual combat, the ALE-50 has successfully countered numerous live firings of both surface-to-air and air-to-air missiles. U.S. military pilots have nicknamed the decoy "Little Buddy". [3] The system requires no threat-specific software, and communicates its health and status to the aircraft over a standard data bus. [4]
The ALE-50 was first deployed in 1995, but is also used on the F/A-18E/F Super Hornet and the B-1B Lancer. [5] The ALE-50 has also been integrated into the next-generation ALQ-184(V)9 ECM pod, creating an integrated threat-protection system that can be carried on a larger number of platforms.
The ALE-50 expendable decoys' estimated value is $22,000 each. A production run of 1,048 units were delivered through October 2010. [3] An additional 226 units of ALE-50 Bravo T3F launchers were produced for U.S. Navy F/A-18 E/F aircraft in September 2014. [6]
The ALE-50 towed decoy is currently operational on the F-16, F/A-18E/F, and B-1B aircraft with more than 25,000 deliveries. [7] [8]
The AIM-120 Advanced Medium-Range Air-to-Air Missile(AMRAAM) ( AM-ram) is an American beyond-visual-range air-to-air missile capable of all-weather day-and-night operations. It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance. When an AMRAAM missile is launched, NATO pilots use the brevity code "Fox Three".
The AIM-54 Phoenix is an American radar-guided, beyond-visual-range air-to-air missile (AAM), carried in clusters of up to six missiles on the Grumman F-14 Tomcat, its only operational launch platform.
The Halifax-class frigate, also referred to as the City class, is a class of multi-role patrol frigates that have served the Royal Canadian Navy since 1992. The class is the outcome of the Canadian Patrol Frigate Project, which dates to the mid-1970s. HMCS Halifax was the first of an eventual twelve Canadian-designed and Canadian-built vessels which combine traditional anti-submarine capabilities with systems to deal with surface and air threats as well. Ships of the class are named after capital cities of Canadian provinces, the capital of Canada, Ottawa, and the major cities of Calgary, Montreal, and Vancouver.
The Boeing EA-18G Growler is an American carrier-based electronic warfare aircraft, a specialized version of the two-seat Boeing F/A-18F Super Hornet. The EA-18G replaced the Northrop Grumman EA-6B Prowlers in service with the United States Navy. The Growler's electronic warfare capability is primarily provided by Northrop Grumman. The EA-18G began production in 2007 and entered operational service with the US Navy in late 2009. Australia has also purchased thirteen EA-18Gs, which entered service with the Royal Australian Air Force in 2017.
The Boeing F/A-18E and F/A-18F Super Hornet are a series of American supersonic twin-engine, carrier-capable, multirole fighter aircraft derived from the McDonnell Douglas F/A-18 Hornet, in service with the armed forces of the U.S., Australia, and Kuwait. The F/A-18E single-seat and F/A-18F tandem-seat variants are larger and more advanced versions of the F/A-18C and D Hornet, respectively.
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.
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.
The ADM-160 MALD is an air-launched, expendable decoy missile developed by the United States. Later variants (MALD-J) are additionally equipped with electronic countermeasures to actively jam early warning and target acquisition radars.
The AN/APG-65 and AN/APG-73 are designations for a family of all-weather multimode airborne radar systems designed by Hughes Aircraft for the F/A-18 Hornet, and used on a variety of fighter aircraft types. The APG-79 is an upgraded AESA version.
The AN/APG-79 is a type of active electronically scanned array (AESA) radar that was developed for use on the United States Navy's Boeing F/A-18E/F Super Hornet and Boeing EA-18G Growler aircraft. The radar's AESA technology provides quick updates on multiple targets, and its solid-state antenna construction makes it more reliable and cost-effective than traditional radar systems. The radar has a range of up to 150 km and can track multiple targets simultaneously. It is capable of firing weapons such as the AIM-120 AMRAAM's D model and guiding multiple missiles to targets located at varying distances and directions. As of July 2008, 100 APG-79 sets had been delivered to the United States Navy, and the Navy expects to order around 437 production radars. In January 2013, the Director, Operational Test & Evaluation (DOT&E) disclosed some issues with the APG-79 radar during its initial operational testing, but upgrades have been made over time.
The AN/ALR-67 radar warning receiver is designed to warn an aircraft's crew of potentially hostile radar activity. It is an airborne threat warning and countermeasures control system built to be successor to the United States Navy's AN/ALR-45. Northrop Grumman Corporation's Electronic Systems sector was the main contractor for the AN/ALR-67(V) and (V)2. Raytheon Electronic Warfare Systems was the main contractor for the AN/ALR-67(V)3.
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.
The AN/ALE-55 Fiber-Optic Towed Decoy, or ALE-55, is an RF countermeasure under development by BAE Systems Electronic Solutions for the F/A-18E/F Super Hornet.
A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust. The aim is to make the infrared-guided missile seek out the heat signature from the flare rather than the aircraft's engines.
The AN/SPY-6 is an active electronically scanned array 3D radar under development for the United States Navy (USN). It will provide integrated air and missile defense for Flight III Arleigh Burke-class destroyers. Variants are under development for retrofitting Flight IIA Arleigh Burkes and for installation aboard Constellation-class frigates, Gerald R. Ford-class aircraft carriers, America-class amphibious assault ships, and San Antonio-class amphibious transport docks.
The AGM-158C LRASM is a stealth air launch anti-ship cruise missile developed for the United States Air Force and United States Navy by the Defense Advanced Research Projects Agency (DARPA). Derived from the AGM-158B JASSM-ER, the LRASM was intended to pioneer more sophisticated autonomous targeting capabilities than the U.S. Navy's current Harpoon anti-ship missile, which has been in service since 1977.
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.
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.
Cooperative Engagement Capability (CEC) is a sensor network with integrated fire control capability that is intended to significantly improve battle force air and missile defense capabilities by combining data from multiple battle force air search sensors on CEC-equipped units into a single, real-time, composite track picture. This will greatly enhance fleet air defense by making jamming more difficult and allocating defensive missiles on a battle group basis.
