The AGR-20 Advanced Precision Kill Weapon System (APKWS) is a design conversion of Hydra 70 unguided rockets with a laser guidance kit to turn them into precision-guided munitions (PGMs). [7] APKWS is approximately one-third the cost and one-third the weight of the current inventory of laser-guided weapons, has a lower yield more suitable for avoiding collateral damage, and takes one quarter of the time for ordnance personnel to load and unload.
Where possible the system utilizes existing Hydra 70 components such as launchers, rocket motors, warheads and fuzes. The weapon bridges the gap between the Hydra 70 and AGM-114 Hellfire systems and provides a cost-effective method of engaging lightly armored point targets. APKWS is the U.S. government's only Program of Record for the semi-active, laser-guided 2.75 inches (70 mm) rocket. [8]
It converts the Hydra 70 unguided rocket into a precision guided munition through the addition of a mid-body guidance unit developed by BAE Systems. The APKWS has also been successfully tested in live fire exercises with the Forges de Zeebrugge unguided rocket, converting it into a precision guided munition and demonstrating the technology can be used on other rocket types than the Hydra 70. [8]
The winning bidder for the APKWS II contract was the team of BAE Systems, Northrop Grumman and General Dynamics, [9] beating the offerings from Lockheed Martin and Raytheon Systems. [10]
The APKWS II uses the Distributed Aperture Semi-Active Laser Seeker (DASALS) technology. This system allows a laser seeker to be located in the leading edge of each of the forward control canards, working in unison as if they were a single seeker. This configuration allows existing warheads from the Hydra 70 system to be used without the need for a laser seeker in the missile nose.
The APKWS II system is composed of the launch platform, rockets equipped with the WGU-59/B mid-body guidance unit, the lengthened 7-tube LAU-68 F/A rocket launcher, the SCS 7 aiming cue (not needed for attack helicopters), and Fastpack PA-140 and CNU-711/E storage kits for rockets and guidance kits, respectively, to ensure they are safe in the field. The WGU-59/B mid-body guidance unit is equipped with DASALS seeker optics which deploy 0.5 seconds after launch. They are attached in between the Mk 66 Mod 4 rocket motor and a warhead and fuze, which increases length by 18.5 in (47 cm) and weight by 9 lb (4.1 kg) over the legacy Hydra system. [5]
Firing ranges are 1,100-5,000 meters, the former of which can be hit less than 5 seconds after firing. [5] Maximum range is constrained by use of the existing Hydra 70 motor, but since the seeker can see as far as 14 km (8.7 mi), a more powerful motor could extend range while retaining accuracy. [11] Nammo is working on a modified rocket motor that can extend range to 12–15 km (7.5–9.3 mi). [12]
A software upgrade of the APKWS will be applied starting in late 2021; the upgrade increases range by 30% by means of an optimized flight trajectory to engage targets at a steeper angle of attack, while also being qualified on both fixed- and rotary-wing aircraft in a single variant and improving the surface danger zone logic for better training range options. [13] [14]
In June 2021, BAE successfully tested the APKWS in a counter-unmanned aerial systems (C-UAS) role. An APKWS-equipped rocket was fitted with a proximity fuze and destroyed a Class 2 UAS. The proximity fuze enables it to intercept UAS at a lower cost than other methods, and due to the rocket's laser guidance that activates on launch it does not require locking on to the target before launch. [15] [16]
In December 2019, the 85th Test and Evaluation Squadron at Eglin AFB, Florida, conducted a test using APKWS rocket against a drone representing a cruise missile. By adapting the rocket for cruise missile defense, it can serve the same role as the much more expensive AIM-120 missile, according to an Air Force release. "The test was unprecedented and will shape the future of how the Air Force executes CMD," Col. Ryan Messer, commander of the 53d Wing at Eglin, said in a release. "This is a prime example of how the 53d Wing is using resources readily available to establish innovative ways that enhance combat capabilities for our combat units." [45]
In June 2020, BAE announced they had completed test firings of the APKWS from a ground launcher for the first time. Several rockets were fired from an Arnold Defense-built launcher called the Fletcher designed specifically for ground vehicles, demonstrating the weapon's ability to address a demand for standoff ground-to-ground precision munitions for small ground units. [46] [47] In April 2024, the U.S. Navy ordered five Electronic Advanced Ground Launcher Systems (EAGLS) for rapid delivery in response to an urgent need to respond to UAS threats in the Middle East. EAGLS is a self-contained system consisting of a four-round APKWS launcher, a sensor turret with EO/IR cameras, and an RPS-40 radar. [48]
The AIM-7 Sparrow is an American medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, United States Marine Corps, and various other air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM.
The AGM-114 Hellfire is an American missile developed for anti-armor use, later developed for precision drone strikes against other target types, especially high-value targets. It was originally developed under the name "Heliborne laser, fire-and-forget missile", which led to the colloquial name "Hellfire" ultimately becoming the missile's formal name. It has a multi-mission, multi-target precision-strike ability and can be launched from multiple air, sea, and ground platforms, including the MQ-1 Predator and MQ-9 Reaper. The Hellfire missile is the primary 100-pound (45 kg) class air-to-ground precision weapon for the armed forces of the United States and many other countries. It has also been fielded on surface platforms in the surface-to-surface and surface-to-air roles.
The Hydra 70 rocket is an American made 2.75-inch (70 mm) diameter fin-stabilized unguided rocket used primarily in the air-to-ground role. It can be equipped with a variety of warheads, and in more recent versions, guidance systems for point attacks. The Hydra is widely used by US and allied forces, competing with the Canadian CRV7, with which it is physically interchangeable.
Starstreak is a British short-range surface-to-air missile that can be used as a man-portable air-defence system (MANPADS) or used in heavier systems. It is manufactured by Thales Air Defence in Belfast, Northern Ireland. It is also known as Starstreak HVM. After launch, the missile accelerates to more than Mach 4, making it the fastest short-range surface-to-air missile in existence. It then launches three laser beam-riding submunitions, increasing the likelihood of a successful hit on the target. Starstreak has been in service with the British Army since 1997. In 2012 Thales relaunched the system as ForceSHIELD.
Brimstone is a ground or air-launched ground attack missile developed by MBDA UK for the UK's Royal Air Force. It was originally intended for "fire-and-forget" use against mass formations of enemy armour, using a millimetre wave (mmW) active radar homing seeker to ensure accuracy even against moving targets. Experience in Afghanistan led to the addition of laser guidance in the dual-mode Brimstone missile, allowing a "spotter" to pick out specific and the highest priority targets, particularly useful to minimise collateral damage when friendly forces or civilians were in the area. The tandem shaped-charge warhead is much more effective against modern tanks than older similar weapons such as the AGM-65G Maverick missile. Three Brimstones are carried on a launcher that occupies a single weapon station, allowing a single aircraft to carry many missiles.
Pacific Missile Test Center (PMTC) is the former name of the current Naval Air Warfare Center, Weapons Division. The name of the center was the Naval Air Missile Test Center prior to PMTC. It is located at Naval Base Ventura County/Naval Air Station Point Mugu in Ventura County, California. The nearest city to the installation is Oxnard.
The 9K121 Vikhr is a Soviet laser-beam-riding anti-tank missile. "9K121" is the GRAU designation for the missile system. The missile can be launched from warships, Ka-50 and Ka-52 helicopters, and Su-25T aircraft, and has a range of approximately 10km. It was first shown publicly at the 1992 Farnborough Airshow.
The Northrop Grumman MQ-8 Fire Scout is an unmanned autonomous helicopter developed by Northrop Grumman for use by the United States Armed Forces. The Fire Scout is designed to provide reconnaissance, situational awareness, aerial fire support and precision targeting support for ground, air and sea forces. The initial RQ-8A version was based on the Schweizer 330, while the enhanced MQ-8B was derived from the Schweizer 333. The larger MQ-8C Fire Scout variant is based on the Bell 407.
The Armement Air-Sol Modulaire, commonly called AASMHammer, is a French, all-weather, smart air-to-surface stand-off weapon developed by Safran Electronics & Defense. Meant for both close air support and deep strike missions, the AASM is highly modular.
The Zuni 5-inch Folding-Fin Aircraft Rocket (FFAR), or simply Zuni, is a 5.0 in (127 mm) unguided rocket developed by the Hunter-Douglas Division of Bridgeport Brass Company and deployed by the United States Armed Forces, and the French Air Force. The rocket was developed for both air-to-air and air-to-ground operations. It can be used to carry various types of warheads, including chaff for countermeasures. It is usually fired from the LAU-10 rocket pod holding four rockets.
The Bell AH-1Z Viper is a twin-engine attack helicopter, based on the AH-1W SuperCobra, designed and produced by the American aerospace manufacturer Bell Helicopter. It is one of the latest members of the prolific Bell Huey family. It is often called "Zulu Cobra", based on the military phonetic alphabet pronunciation of its variant letter.
The Low-Cost Guided Imaging Rocket, officially known as Poniard is a surface-to-ship guided rocket developed by Agency for Defense Development (ADD) and LIG Nex1. The LOGIR was a weapons system under development for the US Navy as part of ONR's Low-Cost Imaging Terminal Seeker (LCITS) FNC. It transitioned as the weapon used in the Medusa Joint Capability Technology Demonstration with South Korea.
The Direct Attack Guided Rocket (DAGR) is a weapons system under development by Lockheed Martin. The program goal is to provide a low cost 2.75 inch (70 mm) precision guided rocket which is compatible with existing Hellfire II systems and launchers in service. The system will use components from the existing Hydra 70 rocket, but differs from other upgrades to the Hydra 70 such as APKWS and LOGIR in that it is designed to be plug and play compatible with the Hellfire missile and use the M299 Hellfire launcher, increasing the load-out by up to four times. DAGR also offers a lock-on before launch capability that is not compatible with the electronics in existing Hydra 70 launchers.
The AGM-176 Griffin is a lightweight, precision-guided munition developed by Raytheon. It can be launched from the ground or air as a rocket-powered missile or dropped from the air as a guided bomb. It carries a relatively small warhead, and was designed to be a precision low-collateral damage weapon for irregular warfare. It has been used in combat by the United States military during the War in Afghanistan.
A precision-guided munition (PGM), also called a smart weapon, smart munition, or smart bomb, is a guided munition intended to hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the Persian Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped.
In military terminology, a rocket is a self-propelled, unguided or guided, weapon-system powered by a rocket engine. Though used primarily as medium- and long-range artillery systems, historically rockets have also seen considerable use as air-to-surface weapons, some use as air-to-air weapons, and even as surface-to-air devices. Examples of modern surface-to-surface rocket systems include the Soviet BM-27 Uragan and the American M270 Multiple Launch Rocket System.
Martlet or the Lightweight Multirole Missile(LMM) is a lightweight air-to-surface, air-to-air, surface-to-air, and surface-to-surface missile developed by Thales Air Defence for the United Kingdom. It is named after a mythical bird from English heraldry that never roosts, the Martlet.
The Boeing Insitu RQ-21 Blackjack, company name Integrator, is an American unmanned air vehicle designed and built by Boeing Insitu to meet a United States Navy requirement for a small tactical unmanned air system (STUAS). It is a twin-boom, single-engine monoplane, designed as a supplement to the Boeing Scan Eagle. The Integrator weighs 61 kg (134 lb) and uses the same launcher and recovery system as the Scan Eagle.
The Northrop Grumman MQ-8C Fire Scout is an unmanned helicopter developed by Northrop Grumman for use by the United States Navy. The MQ-8C also has autonomous take-off and landing capability. It is designed to provide reconnaissance, situational awareness, aerial fire support and precision targeting support for ground, air and sea forces. The MQ-8C airframe is based on the Bell 407, while the avionics and other systems are developed from those used on the MQ-8B Fire Scout. It first flew in October 2013 and achieved initial operational capability on 28 June 2019.
The Ground Launched Small Diameter Bomb (GLSDB) is a weapon developed by Boeing and the Saab Group to allow Boeing's GBU-39 Small Diameter Bomb (SDB), originally developed for use by aircraft, to be ground-launched from a variety of launchers and configurations. It combines the SDB with the M26 rocket, enabling it to be launched from ground-based missile systems such as the M270 Multiple Launch Rocket System and M142 HIMARS.
