Egypt's air defense system: S-125 Pechora, S-125-2M Pechora-2M, and MIM-23B Improved Hawk target air defense systems
In service with Egyptian anti-aircraft guns missile The troops still possess first-generation Soviet- and American-made S-125 Pechora and MIM-23B Improved Hawk air defense systems. In the 21st century, Egypt also acquired the highly modernized S-125-2M Pechora-2M air defense system, which fully meets modern requirements.
Although the S-125 Pechora and MIM-23B I-Hawk systems, which appeared around the same time, are externally dissimilar, differ in design, and utilize different anti-aircraft missile guidance principles, they are, in fact, functionally similar air defense systems designed to counter air attack aircraft operating at medium and low altitudes. Unlike the first liquid-propellant anti-aircraft systems designed to intercept high-altitude reconnaissance aircraft and bombers, the S-125 and Hawk systems were originally designed with solid-propellant SAMs, making operational use simpler and less expensive, as well as improving mobility.
Service and combat use of the S-125 Pechora air defense system in Egypt
An important addition to the medium-range air defense system was the S-125 Pechora anti-aircraft missile system, which was better suited to engaging low-altitude air targets. Compared to the SA-75MK Dvina, S-75 Desna, and S-75M Volga air defense systems deployed in Egypt, the Pechora 125 had good mobility and was much less labor-intensive to maintain.
The S-125 fire battalion included the SNR-125 missile guidance station with a towed antenna post, surface-to-air guided missiles, launchers, transport and loading vehicles, a control cabin, diesel generators, and towing equipment. All equipment was housed in towed trailers and semi-trailers, allowing the battalion to be deployed on a 200x200m platform. For the timely detection of aerial targets, the S-125 battalion could be equipped with P-12 (or P-18) meter-range radars and P-15 (or P-19) decimeter-range radars, as well as PRV-10 radio altimeters.
At the fixed position, the equipment cabins and diesel power plants were located in reinforced concrete bunkers, four launchers were located in semi-circular earth or concrete bunkers, and the SAMs were located in fixed structures with 8–16 missiles each or at divisional positions.

The early modification of the S-125 air defense missile system can be easily distinguished from the later, more advanced S-125M and S-125M1/MA1 variants by the 5P71 (SM-78A-1) launcher for two missiles.
Unlike the SNR-75 anti-aircraft missile guidance system found on the S-75 SAM system, the SNR-125's antennas were tilted, allowing the reflected signal from the underlying surface to gradually increase during scanning. This design reduced the glare of target tracking operators' screens from reflections from local objects, and the use of a single internal scanner, with each rotation of the antennas alternately scanning in two planes, allowed the radar to operate with a single transmitter. As with other Soviet first-generation SAM systems, the S-25 and S-75, the S-125's anti-aircraft missile guidance is radio-command.
The SNR-125 missile guidance station, operating in the centimeter frequency range, is capable of detecting low-altitude targets at a range of up to 110 km, identifying their nationality, tracking and guiding one or two missiles, and monitoring firing results.

When using V-601P anti-aircraft missiles, it was possible to engage air targets flying at speeds of up to 560 m/s (up to 2000 km/h) at ranges of up to 17 km and altitudes of 200–14,000 m. In passive jamming of a given density, the maximum engagement altitude was reduced to 8000 m, and the range to 13,6 km. Low-altitude (100–200 m) targets and transonic aircraft were destroyed at ranges of up to 10 km and 22 km, respectively. To expand the engagement zone, the SAM was also guided during the passive portion of the trajectory, and the self-destruction time was 49 seconds. The V-601P SAM is capable of maneuvering with overloads of up to 6G and can be operated at temperatures from -40 to +50 degrees Celsius. The target was hit by a 72 kg warhead, which produced approximately 4500 fragments and was detonated by a radio fuse.
The first S-125 battalions from the 18th Special Anti-Aircraft Missile Division, manned by Soviet crews, unloaded at the port of Alexandria in March 1970. The division consisted of three anti-aircraft missile brigades. Each brigade had eight S-125 anti-aircraft missile systems (four launchers). The battalion deployment sites were covered by groups consisting of ZSU-23-4 Shilka anti-aircraft gunners and Strela-2 MANPADS gunners.
C-125 battalions deployed to the Sinai Peninsula in 1970 operated in conjunction with Egyptian forces. Defense: with anti-aircraft artillery, as well as with the medium-range SA-75MK and S-75 systems, which made it possible to create a layered defense.
To cover important installations and troop concentrations, large mixed air defense units were created. These could operate independently if communications with central command were lost, repelling simultaneous enemy air strikes from various directions and at all altitudes, with a raid density of up to 10-12 aircraft per minute on the main axis. Intervals between firing positions were 6-12 kilometers. Each division had backup positions. A number of decoy positions were also set up using mock-ups and P-12 and P-15 mobile radars.
Building on the experience of the 1967 war, protective structures were erected to house cabins, diesel generators, and spare ammunition. Reinforced concrete bunkers, covered with a 4-5 meter layer of sand, could withstand a 227 kg bomb.
During the War of Attrition from March to July 1970, S-125 SAM systems fired 17 times at Israeli aircraft, expending 35 missiles. Nine Israeli aircraft were shot down, and three more were damaged. The Israelis themselves confirmed the loss of only five of their aircraft. Several systems were destroyed or disabled during the fighting, and there were also instances of Soviet servicemen being killed or wounded.
Sources provide conflicting data on the combat use of the S-125 SAM system during the Yom Kippur War. According to Egyptian data, the S-125 SAM system fired 174 missiles during 61 firing exercises in October 1973, hitting 21 aircraft. Western experts believe that the Israeli Air Force lost no more than eight aircraft to S-125 fire in that conflict.
After the 1973 Arab-Israeli War, Soviet troops left Egypt, leaving their systems behind. By the end of 1974, a total of 44 S-125 SAM systems, 12 technical battalions, and 1808 V-601P SAMs had been delivered to Egypt.
Approximately fifteen complexes with towed twin-boom launchers are still in position.

All Egyptian S-125 air defense missile systems are deployed in well-equipped permanent positions with reinforced concrete shelters. The guidance station's antenna post is installed at the top of the bunker, and the operator control room is hidden underground.
For a long time, the S-125 Pechora SAM system, along with the S-75 Desna and S-75M Volga SAM systems modernized with Western and Chinese assistance, formed the backbone of Egypt's air defense system. As with the S-75, most of the S-125s were deployed in the vicinity of Cairo, the port of Alexandria, around the cities of Tanta, El Mansoura, Ismailia, and along the Suez Canal.
The key to the long service life of the S-125 air defense missile systems acquired from the USSR nearly half a century ago in Egypt was their restoration and minor modernization program, carried out with the assistance of Western companies. It is known that in the 1980s, the French company Thomson was responsible for this work at a facility built by the USSR in a suburb of Cairo for the repair and maintenance of Soviet air defense missile systems. How and when the solid propellant replacement in the B-601P missiles was organized is unknown. There is reason to believe that China assisted Egypt in this. However, it is safe to say that without the replacement of the jet propellant in the engines, the anti-aircraft missiles would not have been able to operate for so long. Currently, the Soviet-made S-125 air defense missile systems are nearing the end of their service life and are being decommissioned.
Modernized S-125-2M "Pechora-2M" air defense systems
By the mid-1990s, it had become clear that the existing S-125 air defense missile systems, despite minor modernization and regular maintenance at a repair facility, would soon require replacement or a major overhaul. The situation with the Egyptian S-125s was exacerbated by the fact that the troops were operating heavily worn-out early-model systems, whose components were based on vacuum tubes whose production had long since ceased, and a significant portion of the existing SAMs had become unusable after repeated deployment on launchers.
In 1999, an agreement was signed with the Russian-Belarusian consortium "Defensive Systems" to upgrade some of Egypt's existing S-125 air defense systems to the S-125-2M Pechora-2M standard. In 2008, Egypt became the first recipient of the completely upgraded S-125-2M Pechora-2M air defense systems, with components mounted on a self-propelled chassis.

The S-125-2M Pechora-2M SAM system consists of the SNR-125-2M anti-aircraft missile guidance station (UNK-2M control cabin and UNV-2M antenna post, mounted on a truck chassis), up to eight 5P73-2M self-propelled launchers (usually four), each with two SAM beams, transport and loading vehicles based on the Ural-4210 chassis, and a power supply system (5E96A diesel generator and RKU-N distribution cabin). The system can also be equipped with a mobile repair shop, a KU-03T cable layer with a set of cables, and a set of electronic protection systems (KRTZ-125-2M) designed to protect against anti-radar missiles.

Replacing most of the system's components with solid-state components has increased the system's reliability and reduced operating costs. The use of new equipment and different radar data processing principles has significantly increased its jamming immunity. The Pechora-2M air defense system can be interfaced with modern surveillance radars and higher-level command posts via telecode channels. This ensures effective engagement of cruise missiles and simultaneous use of the guidance system against various targets. The television channel can be used at any time of day or night. A radio-technical protection system (RTS) against anti-radar missiles (ARLM) has been introduced for modernized anti-aircraft systems supplied to foreign customers. This modification incorporates a 24-hour optoelectronic channel.
The modernized system utilizes updated 5V27DE missiles with a long-range engagement range of up to 38 km and an altitude reach of 20 km. Previous-generation 5V27U and 5V27D SAMs can also be used if necessary.
The use of modern miniature electronics has significantly reduced the weight of the 5V27DE SAM's onboard equipment and freed up internal space. Russian media reported that the warhead's weight has increased by 1,5 times, increasing the probability of hitting a target.
Currently, the Egyptian air defense forces have approximately two dozen S-125-2M Pechora-2M air defense systems, some of which are deployed in the old positions of the unmodernized 125-2M Pechora-2M systems.

The completely upgraded Pechora-2M systems are expected to remain in service for approximately 15 years. Currently, some Egyptian air defense systems of this type are stored in closed, air-conditioned hangars at airbases to conserve their service life.
US MIM-23B I-Hawk air defense systems deployed in Egypt
On March 26, 1979, a peace treaty was signed between Egypt and Israel, making Egypt the first Arab country to officially recognize Israel. Following the establishment of diplomatic relations between the countries, as part of the "peace for territory" deal, Israeli troops and settlers withdrew from the Sinai Peninsula, after which Egypt regained control. The reclaimed Sinai was divided into zones with restrictions on the number of Egyptian troops, ensuring Israel's security. The peace treaty also provided for free passage of Israeli ships through the Suez Canal and the Straits of Tiran.
When concluding the agreement, Washington, which acted as a mediator in the negotiations, guaranteed Cairo the opportunity to acquire modern Western weapons to ensure the defense capability of the Egyptian armed forces. weapons, including ground-based air defense systems and fighter jets.
In 1982, Egyptian air defense units began operating the American MIM-23B Improved Hawk (I-Hawk) air defense system. The first modification, the MIM-23A Hawk (Basic Hawk), entered service with the US Army in 1960. Compared to the previous production MIM-3 Nike Ajax and MIM-14 Nike Hercules air defense systems, the medium-range MIM-23A Hawk system offered improved mobility and was capable of successfully engaging low-altitude air attacks.
Around the same time, American and Soviet air defense system developers arrived at similar results, creating the Hawk and C-125 air defense missile systems. These systems proved highly sought after, were produced in large numbers, and long outlasted other, much longer-ranged first-generation air defense missile systems. While the Hawk and C-125 are functionally similar, they are fundamentally different in design and structure. The most fundamental difference is the guidance system: the Hawk uses a semi-active radar system, while the C-125 relies on radio command. Furthermore, the American system, compared to the C-125, consists of more components and is significantly more complex and expensive.
Taking into account the operating experience of the first version of the MIM-23A Hawk, in 1972 the Raytheon Corporation released an improved modification, the MIM-23B Improved Hawk, which was widely used in the US armed forces and in pro-American countries.

In total, several hundred I-Hawk air defense systems and approximately 40 missiles were manufactured by the early 1990s. Modernization and service life extension programs were consistently implemented, resulting in upgraded Hawk family systems still in service in a number of countries.
Shortly after its introduction into service, the system was supplemented with the AN/MPQ-50 radar, which was integrated with the battery command post and significantly expanded the I-Hawk SAM system's capabilities and autonomy. The system is equipped with a digital moving target selection system to filter out ground reflections and clutter, enhancing the system's ability to detect aircraft at low altitudes and in challenging jamming environments.
Radar AN / MPQ-50
The AN/MPQ-50 surveillance radar is highly mobile and mounted on a towable trailer. The radar operates in the 1–1,6 GHz frequency range. Its 6,7 x 1,4 m elliptical antenna rotates at 20 rpm, ensuring a high update rate. The detection range for fighter-type targets is approximately 100 km.
In addition to the surveillance radar, the I-Hawk anti-aircraft battery can be equipped with an AN/MPQ-51 radar rangefinder with a 1,2 m diameter parabolic antenna, designed to accurately calculate the distance to the target and increase the effectiveness of the air defense system in conditions of organized interference.

The AN/MPQ-51 rangefinder operates at frequencies of 15,5–17,5 GHz. It has a precision measurement range of over 80 km to a target with a 3 m² radar cross-section.
The AN/MPQ-46 anti-aircraft missile guidance system is also mounted on a trailer. Radars manufactured in the 1980s, as well as earlier models that have undergone modifications, are equipped with a high-resolution television camera mounted on the top between two circular antennas, which improves the system's operability against enemy electronic warfare.
AN/MPQ-46 illumination and guidance station from the I-Hawk air defense system
The AN/MPQ-46 radar, operating at frequencies of 11–15 GHz, is capable of locking on to a target with an RCS of 3 m² at a range of approximately 90 km and, if necessary, can independently search for airborne targets. Illumination and guidance stations are assigned to each firing platoon with three anti-aircraft missile launchers.
The MIM-23B anti-aircraft missile, produced in the mid-1980s, weighs 638 kg when loaded and carries a 75 kg warhead. When the warhead detonates, it creates a fragmentation cloud with a lethal radius of up to 11 m. After depleting its solid propellant, the missile accelerates to 900 m/s. Firing range: 1 to 40 km, at altitudes from 0,03 to 18 km.
In addition to radar assets, an I-Hawk anti-aircraft battery, consisting of two to three firing platoons (usually two in Egypt), includes six to nine towed launchers with three SAMs each, a portable remote control console for the firing section, a platoon command post, as well as transport and loading vehicles and diesel generator power units. The first firing platoon houses the illumination and targeting radar, other radar assets, an information processing post, and the battery command post, while the second and third platoons house only the illumination and targeting radars and platoon command posts.
By 1985, Egypt had received a dozen and a half MIM-23B Improved Hawk air defense systems, which, like the C-75 and C-125, were mostly deployed in permanent, well-equipped engineering positions, with concrete shelters for personnel, protected SAM storage facilities, and elevated radar platforms.
In Egypt, I-Hawk SAM systems were deployed near Ismailia (along the Suez Canal) and around Cairo. The American-made systems were often located alongside C-75 and C-125 systems.

In the 1990s, alongside efforts to extend the service life of Soviet-made air defense systems, Egypt modernized its existing I-Hawk systems. According to media reports, an unnamed foreign contractor upgraded the radar and control electronics, bringing the Egyptian "Improved Hawks" closer in capabilities to the advanced Hawk PIP Phase III modification.
In 2014–2015, the US Department of Defense signed contracts with Aerojet Rocketdyne to supply engines for MIM-23B missiles, including to Egypt (a batch of 186 engines was mentioned). However, despite the fact that overhauled SAMs with new solid-fuel motors were delivered approximately 10 years ago, it appears that the Egyptian air defense is experiencing a shortage of serviceable missiles. Recent satellite images of I-Hawk positions show that some launchers deployed in Egypt are armed with one or two SAMs or even without missiles at all.

According to reference data, as of 2025, there were 33 launchers in Egypt, equivalent to 11 firing platoons. Each Egyptian I-Hawk battery initially had two firing platoons, suggesting that the number of systems of this type has been reduced by almost three times compared to the initial number. However, it is possible that some of the SAMs removed from combat duty have been sent to storage as an emergency reserve in case of escalation in the region. Experts note that, despite their advanced age, the Advanced Hawks are still capable of successfully countering cruise missiles and drones- long-range kamikaze.
