It was designed to be a much more mobile counterpart to the MIM Nike Herculestrading off range and altitude capability for a much smaller size and weight. Its low-level performance was greatly improved over Nike through the adoption of new radars and a continuous wave semi-active radar homing guidance ihawm.

Hawk was originally intended to attack aircraft, especially those flying at medium and low altitudes. It entered service with the Army in this role in In it underwent a major improvement program as the Improved Hawkor I-Hawkwhich made several improvements to the missile and replaced all of the radar systems with new models.

Improvements continued throughout the next twenty years, adding improved ECCMa potential home-on-jam feature, and ina new warhead that made it capable against short-range tactical missiles. Ihawi reported that the original system’s single shot kill probability was 0.

Approximately 40, of the missiles were produced. Development of the Hawk missile system began inwhen the United States Army began studies into a medium-range semi-active radar homing surface-to-air missile.

In July development contracts where awarded to Northrop for the launcher, radars and fire control systems, while Raytheon was awarded the contract for the missile. Very early missiles used the Aerojet M22E7 which was not iahwk the problems were resolved with the adoption of the M22E8 engine. The high complexity of the system, and the quality of tube -based electronics, gave the radars in the early Hawk systems a mean time between failures MTBF of only 43 hours.

The improved Hawk system loadihg this to between and hours.

Later Hawk versions improved this further to between and 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. This involved numerous upgrades to the Hawk system:. Ihawm system entered service duringthe first unit reaching operational status by October.

All US units were upgraded to I-Hawk standard by A former “black program” from the s that hid special Hawk missiles with passive sensors within select US Army Hawk batteries deployed in Europe. Most of the soldiers, except a small group in each unit, were completely unaware of the special equipment which included a special separate sensor disguised as a load bank on heavy generators, firing displays and power generation equipment that made it all work.

The Hawk system consists of a large number of component elements. These elements were typically fitted on wheeled trailers making the system semi-mobile.

During the system’s year life span, these components were continually upgraded. The Hawk missile is transported and launched from the M towed triple-missile launcher. A self-propelled Hawk launcher, the SP-Hawk, was fielded inwhich simply mounted the launcher on a tracked M modified Mhowever the project was dropped and all activity terminated in August The missile is propelled by a dual thrust motor, with a boost phase and a sustain phase. The MIMB and later missiles are fitted with an M motor with a 5-second boost phase and a sustain phase of around 21 seconds.

The M motor has greater thrust, thus increasing the engagement envelope. The original MIMA 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 MIMB 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 s to give the missile enhanced ECCM ability and to increase the Doppler frequency resolution. The Hawk loaidng has a slender cylindrical body and four long chord clipped delta-wings, extending from mid-body to the slightly tapered boat-tail.

Each wing has a trailing-edge control surface. The original missile used with the system. The new warhead produces approximately 14, 2-gram 0. The ihaqk M rocket motor has a boost phase of 5 seconds and a sustain phase of 21 seconds. This new motor improves the engagement envelope to 1. The missile was operational in All US units had converted to this standard by It consists of the following components: Unknown upgrade to the MIMC. The C and D missile families remained separate until the missiles’ exit from service.

It is not clear exactly what the difference between the two missiles – however it seems likely that the D family missiles represent an alternative guidance system, possibly home on jam developed in response to Soviet ECM techniques that were used by Iraq during the Iran-Iraq War. The missile also includes a new fuse to make it effective against ballistic missiles. The original Hawk system used 4 or in some models 6 radars: As the system was upgraded the functionality of some of the radars was merged.

The final iteration of the system loadng of only 2 radars, an enhanced phased array search radar and lhawk engagement radar HPIR. The radar operates in the 1. The antenna is a 6. The system has a mean time between failure of around hours, and can track at least 60 targets at once. This X Band Continuous wave system is used to detect targets. The unit comes mounted on its own mobile trailer. The unit acquires targets through degrees of azimuth while providing target radial speed and raw range data.

The Improved Hawk version of the CW acquisition radar doubled the output power and improved the detection ranges:.

Frequency modulation is applied to the broadcast on alternate scans of the ICWAR to obtain range information. Some changes to the signal processing allow the radar to determine the targets’ range and speed in a single scan. The HPIR automatically acquires and tracks designated targets in azimuth, elevation and range.

These returns are compared with the missile reference signal being transmitted directly to the missile by the HPIR. Target tracking is continued throughout the missile’s flight. Unit automatically acquires and tracks designated targets in azimuth elevation and range rate. The system uhawk an output power of around Ihawkk operating in the 10— Many of the electron tube components in earlier radars are replaced with solid-state technology. The majority of the remaining tube electronics are upgraded to solid state.

The I-TAS which was field tested in added an Infra Red capability for night operation as well as automatic target detection and tracking. Upgraded with the addition of the LASHE Low-Altitude Simultaneous Hawk Engagement system, which allows the Hawk to engage multiple low level targets by employing a uhawk beam antenna to provide a wide-angle, low-altitude illumination pattern to allow multiple engagements against saturation raids.

This antenna is rectangular. This allows up to 12 targets to be engaged at once. Pulse radar that automatically comes into operation if the HPIR 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. A Ku Band Freq: C4I unit, enabling modern command, control, communications and Force Operation. Loaving displays with 3D map overlays enhance the situation awareness. Introduces the real-time exchange of air picture and commands between the Hawk units. They have also modified their system for engagements at altitudes up to 24, m.

Inawk composite system firing AIM-7 Sparrow missiles from a modified 8 round launcher. The system was demonstrated at the China Lake weapons test site in There are currently no users of the system.

The normal battery radar is used for the engagement, with the missile’s own radar used for terminal homing. Raytheon and Kongsberg loxding offering this system as an upgrade to the existing Hawk system. As part of what became known as the Iran—Contra affairHawk missiles were some of the weaponry sold to Iran, in violation of an arms embargo, to fund the Contras. In Iran announced that it will mass-produce its next generation of air defense system called Mersadwhich would integrate with the Shahin missile.

The NOAH system became operational in The ACWAR programme was initiated to meet increasingly severe tactical air defence requirements and the equipment is being designed for loadlng of Hawk in the late s and beyond.
