The Raytheon MIM-23 HAWK is an American medium range surface-to-air missile. HAWK is an acronym or possibly a backronym for Homing All the Way Killer. The HAWK was initially designed to destroy aircraft and was later adapted to destroy other missiles in flight. The missile entered service in 1960, and a program of extensive upgrades has kept it from becoming obsolete. It was superseded by the MIM-104 Patriot in US Army service by 1994. It was finally phased out of US service in 2002, the last users, the US Marine Corps replacing it with the man-portable FIM-92 Stinger. The missile was also produced outside the US in Western Europe and Japan.
It saw combat in a variety of wars, although it was never fired in anger by US forces. Approximately 40,000 of the missiles were produced.
Janes reports that the original systems single shot kill probability was 0.56, I-HAWK improved this to 0.85.
Development
Development of the HAWK missile system began in 1952, when the US Army began studies into a medium range semi-active radar homing surface to air missile. In July 1954 development contracts where awarded to Northrop for the launcher, radars and fire control systems, while Raytheon was awarded the contract for the missile. The first test launch of the missile then designated the XSAM-A-18 happened in June 1956. By July 1957 development was completed, by which time the designation had changed to XM3 and XM3E1. Very early missiles used the Aerojet M22E7 which was not reliable; the problems were resolved with the adoption of the M22E8 engine.The missile was initially deployed by the US Army in 1959, and by the US Marine Corps in 1960.
The high complexity of the system, and the quantity of tube based electronics gave the radars in the early hawk systems a MTBF of only 43 hours. The improved HAWK system increased this to 130 to 170 hours. Later HAWK versions improved this further to between 300 and 400 hours.
Improved HAWK or I-HAWK The original HAWK system had problems engaging targets at low altitude - the missile would have problems picking the target out against ground clutter. The US army began a program to address these issues in 1964 — the HAWK Improvement Program (HAWK/HIP). This involved numerous upgrades to the Hawk system:
- A digital data processing central information coordinator for target processing, threat ordering, and intercept evaluation.
- An improved missile (MIM-23B) with a larger warhead, smaller and more powerful M112 motor, and improved guidance section.
- The PAR, CWAR, HPI, and ROR were replaced by upgraded variants (see #Radars).
Product Improvement Plan In 1973 the U.S. Army started an extensive multi-phase Hawk PIP (Product Improvement Plan), mainly intended to improve and upgrade the numerous items of ground equipment.
- Phase I
- : Phase I involved replacement of the CWAR with the AN/MPQ-55 Improved CWAR (ICWAR), and the upgrade of the AN/MPQ-50 PAR to Improved PAR (IPAR) configuration by the addition of a digital MTI (Moving Target Indicator). The first PIP Phase I systems were fielded between 1979 and 1981.
- Phase II
- : Developed from 1978 and fielded between 1983 and 1986. upgraded the AN/MPQ-46 HPI to AN/MPQ-57 standard by replacing some of the vacuum tube based electronics with modern solid-state circuits, and added an optical TAS (Tracking Adjunct System). The TAS, designated OD-179/TVY, is an electro-optical (TV) tracking system that increases HAWK operability and survivability in a high-ECM environment.
- Phase III
- : The PIP Phase III development was started in 1983, and was first fielded by U.S. forces in 1989. Phase III was a major upgrade which significantly enhanced the computer hardware and software for most components of the system, a new CWAR the AN/MPQ-62, added single-scan target detection capability, and upgraded the HPI to AN/MPQ-61 standard by addition of a Low-Altitude Simultaneous Hawk Engagement (LASHE) system. LASHE allows the Hawk system to counter saturation attacks by simultaneously intercepting multiple low-level targets. The ROR was phased out in Phase III Hawk units.
HAWK Missile Restore Reliability (MRR)
- This was a program that ran between 1982 and 1984 intended to improve missile reliability.
HAWK ECCM
- Running alongside the MMR program, this produced ECCM to specific threats, probably contemporary Soviet ECM pods such as the SPS-141 fitted to the Su-22, which proved moderately effective during the Iran-Iraq War. The MIM-23C and E missiles contain these fixes.
Low clutter enhancements
- Upgrades to the missile that takes it up to MIM-23G that enable the missile to deal with low flying targets in a high clutter environment. These were first deployed in 1990.
HAWK missile ILM (Improved lethality modification)
- To improve the lethality of the warhead of the missile against ballistic missiles, the warhead was redesigned to produce fewer larger fragments, typically 35 grams each comparable to a 12.7 mm projectile in mass.
HAWK mobility and TMD upgrades
- A HAWK mobility survivability enhancement programme has been developed following experience in the 1990 Gulf War. The aim of this programme was to reduce the number of support vehicles per battery and to increase survivability. Upgrades to the launcher allow missiles to be transported on the launcher itself, as well as replacing vacuum tubes with a single laptop computer. A north finding system speeds orientation and launcher alignment. A field wire replaces heavy cables and allows for greater dispersion amongst battery vehicles from 110 m to 2 km. The upgrades where deployed by the US Marine Corps between early 1995 and September 1996.
Phase IV
- With both the Army and USMC abandoning the HAWK, phase IV was never completed. However it was planned to include:
- * High mobility continuous wave acquisition radar to improve detection of small UAVs.
- * A new CW engagement radar.
- * Anti-radiation missile decoys.
- * An improved missile motor.
- * An upgraded electro-optical tracker.
- * Improved command and control.
- * ATBM upgrades.
HAWK XXI (HAWK 21)
- The HAWK XXI or HAWK-21 is a more advanced, and more compact version of HAWK PIP-3 upgrade. HAWK-XXI basically eliminates the PAR and CWAR radars with the introduction of 3D MPQ-64 Sentinel radars. Norway's Kongsberg Company provides a FDC (Fire Distribution Center) as it is used in NASAM system in Norway. The missiles are upgraded MIM-23K standard with an improved blast-fragmentation warhead that creates a larger lethal zone. The system is also effective against short range tactical ballistic missiles.
- A MPQ-61 HIPIR radar provides low altitude and local area radar coverage as well as continuous wave radar illumination for the MIM-23K Hawk missilles.
Description
The Hawk system consist of a large number of component elements. These elements where typically fitted on wheeled trailers making the system semi-mobile. During the system's 40-year life span, these components were continually upgraded.
The Hawk missile is transported and launched from the M192 towed triple-missile launcher. A self propelled Hawk launcher, the SP-HAWK, was fielded in 1969, which simply mounted the launcher on a tracked M727 (modified M548), however the project was dropped and all activity terminated in August 1971.
The missile is propelled by a dual thrust motor, with a boost phase and a sustain phase. The MIM-23A missiles were fitted with a M22E8 motor which burns for 25 to 32 seconds. The MIM-23B and later missiles are fitted with a M112 motor with a 5 second boost phase and a sustain phase of around 21 seconds. The M112 motor has greater thrust, thus increasing the engagement envelope.
The original MIM-23A missiles used a parabolic reflector, but the antenna directional focus was insufficient, when engaging low flying targets the missile would dive on them, only to lose them in the ground clutter. The MIM-23B I-HAWK missiles and later uses a low side lobe, high-gain plane antenna to reduce sensitivity to ground clutter in addition to an inverted receiver developed in the late 1960s to give the missile enhanced ECCM ability and to increase the Doppler frequency resolution.
A typical Basic Hawk battery consists of:
- 1 x PAR - Pulse Acquisition Radar - Search radar - 20 rpm rotation - for high/medium altitude target detection.
- 1 x CWAR - Continuous Wave Acquisition Radar - Search doppler radar - 20 rpm rotation - for low altitude target detection.
- 2 x HPI - High Power Illuminator doppler Radar - target tracking, illumination and missile guidance.
- 1 x ROR - Range Only Radar - K-band pulse radar provides range information when the other systems are jammed or unavailable.
- 1 x ICC - Information Coordination Central
- 1 x BCC - Battery Control Central
- 1 x AFCC - Assault Fire Command Console - miniature battery control central for remote control of one firing section of the battery. The AFCC controls one CWAR, one HPI, and three launchers with a total of nine missiles.
- 1 x PCP - Platoon Command Post
- 2 x LCS - Launcher Section Controls
- 6 x M-192 - Launchers with 18 missiles.
- 6 x SEA - Generators 56 kVA each.
- 12 x M-390 - Missile transport pallets with 36 missile
- 3 x M-501 - Missile loading tractors.
- 1 x Missile test shop.

- * 65 km (CW) to 60 km (FM) versus 2.4 m² target.
- * 52 km (CW) to 48 km (FM) versus 1 m² target.
- AN/MPQ-55 (Phase I - Phase II)
- AN/MPQ-62 (Phase III)
HPI High Power Illuminator
The early AN/MPQ-46 High Power Illuminator (HPI) radars had only the two large dish-type antennas side by side, one to transmit and one to receive. The HPI automatically acquires and tracks designated targets in azimuth, elevation and range. It also serves as an interface unit supplying azimuth and elevation launch angles computed by the Automatic Data Processor (ADP) in the Information Coordination Centre (ICC) for up to three launchers. The HPI J-band energy reflected from the target is also received by the HAWK missile. These returns are compared with the missile reference signal being transmitted directly to the missile by the HPI. Target tracking is continued throughout the missile's flight. After the missile intercepts the target the HPI Doppler data is used for kill evaluation. The HPI receives target designations from one or both surveillance radars via the Battery Control Centre (BCC) and automatically searches a given sector for a rapid target lock on. The HPI incorporates ECCM and BITE.
- AN/MPQ-33/39 (Basic Hawk)
- AN/MPQ-46 (Improved Hawk - Phase I)
- Range (source Janes):
- * 99 km (high PRF) to 93 km (low PRF) versus 3 m² target.
- * 93 km (high PRF) to 89 km (low PRF) versus 2.4 m² target.
- * 75 km (high PRF) to 72 km (low PRF) versus 1 m² target.
- AN/MPQ-57 (Phase II)
- * HEOS Germany, Netherlands and Norway have modified their HAWK systems with an alternative IR acquisition and tracking system known as the HAWK Electro-Optical Sensor (HEOS) in place of the TAS. HEOS operates in the 8 to 11 µm band and is used to supplement the HPI to acquire and track targets before missile launch.
- AN/MPQ-61 (Phase III)
ROR Range Only Radar
Pulse radar that automatically comes into operation if the CWAR radar cannot determine the range, typically because of jamming. The ROR is difficult to jam because it operates only briefly during the engagement, and only in the presence of jamming.
