Key Information

The Type 72Z tank (also known as the T-72Z and the Safir-74,[5] and the Al-Zubair I in Sudan)[4] is a highly modernized version of the Type 59 and T-54/T-55 tanks,[5] with upgrades carried out by the Iranian Defense Industries Organization.[3]

The tank is not to be confused with an Iraqi modernization also known as T-72Z, said to carry a 125 mm gun.[6]

History

[edit]

The Type 72Z was first announced by the Islamic Revolutionary Guard Corps in 1996.[5] The upgrades to the Type 59 and T-54/T-55 tanks were carried out by the Vehicle Industries Group of the Defence Industries Organization, in order to extend the service life of tanks already in use with the Iranian army.[3]

Upgrades

[edit]

The 100mm gun of the T-55/Type 59 was replaced with an Iranian-produced derivative of the 105mm M68 gun, capable of firing 9M117 Bastion anti-tank guided missiles as well as NATO standard ammunition.[3][4][7] The Slovenian Fotona Electronic Fire Control System (EFCS-3-55) was added, with automatic and manual gun stabilizers, a laser rangefinder, second-generation night sights, a ballistic computer, and an independent viewer and target designation system for the commander.[3][4][5] Electric smoke grenade dischargers were also added to provide concealment on top of the existing ability to create a smoke screen by injecting diesel fuel into the left exhaust outlet.[3][4][8]

Explosive reactive armor (ERA) developed by the Shahid Kolah Dooz Industrial Complex can be fitted to the Type 72Z, providing protection against projectiles and napalm-type weapons. Side track skirts similar to those on the Type 59 were added to T-54/T-55 tanks upgraded with ERA. [3]

The engine was replaced with a Ukrainian 780 hp V46-6 diesel engine,[4][5] together with the SPAT-1200 transmission system.[3] Air conditioning, power steering and a fire suppression system are also believed to have been installed.[8]

Type 72Z

View on Grokipedia
from Grokipedia
The Type 72Z, also designated Safir-74, is an Iranian main battle tank resulting from extensive upgrades to Soviet T-54/T-55 and Chinese Type 59 platforms by the Defense Industries Organization. These modifications, unveiled in 1996, addressed obsolescence in Iran's tank inventory, much of which originated from captures during the Iran-Iraq War or pre-revolutionary acquisitions. Key enhancements include replacement of the original 100 mm gun with a 105 mm M68 rifled main armament sourced from U.S. stocks, integration of a Slovenian EFCS-3 fire control system with laser rangefinder, and addition of Iranian-developed explosive reactive armor over the legacy cast turret and hull. Mobility was improved via a new V-46 series diesel engine delivering 780 horsepower, enabling a top speed of 65 km/h and operational range of 510 km on torsion bar suspension. Primarily serving the Iranian armed forces, variants have been exported to Sudan, where Type 72Z tanks have participated in ongoing civil conflicts against paramilitary forces. Despite these upgrades, the design retains inherent vulnerabilities of its 1950s origins, such as limited internal layout for modern electronics and base armor insufficient against advanced anti-tank threats without ERA coverage.

Development and History

Origins from T-54/55 and Type 59 Tanks

The Type 72Z, also designated T-72Z or Safir-74, traces its origins to Iran's efforts to refurbish its fleet of obsolescent Soviet T-54 and T-55 main battle tanks, alongside Chinese Type 59 models, which formed the backbone of its armored forces during and after the Iran-Iraq War (1980–1988). The T-54 and T-55 series, introduced by the Soviet Union in the late 1940s and 1950s, featured a 100 mm rifled gun, sloped composite armor, and a torsion bar suspension system, but by the 1990s, these tanks suffered from outdated fire control, limited mobility, and vulnerability to modern anti-tank weapons. The Type 59, entering production in China in 1959 under license, replicated the T-54A design with minor adaptations, including a similar 100 mm D-10T gun and 520 horsepower V-12 diesel engine, producing over 10,000 units for export and domestic use. Iran's acquisition of these platforms included purchases of approximately 200 Type 59 tanks from China via a $1.6 billion arms deal signed in March 1985, supplemented by captures of hundreds of Iraqi T-54s and T-55s during the war, bolstering its inventory amid Western arms embargoes. These vehicles, while numerous and reliable in basic operations, required extensive upgrades to counter evolving threats from Iraqi T-72s and Western-equipped forces. The modernization initiative, launched under Iran's Defense Industries Organization (DIO) and executed by the Shahid Kolah Dooz Industrial Complex, a subsidiary of the DIO's Tank Modernization Industries, aimed to retrofit existing hulls and turrets rather than design a new tank, preserving logistical compatibility while incorporating locally produced or reverse-engineered components. Initial prototypes of the Type 72Z emerged in 1996, demonstrated with the Islamic Revolutionary Guard Corps, marking the program's shift from conceptual upgrades to operational testing on captured T-54/55 chassis and imported Type 59s. This approach extended the tanks' viability into the 21st century, with an estimated 400 units eventually upgraded, though production emphasized incremental enhancements over radical redesign to address resource constraints in Iran's sanctioned defense sector.

Iranian Modernization Initiative (1990s–2000s)

In the aftermath of the Iran-Iraq War (1980–1988), Iran possessed substantial inventories of Soviet T-54/55 and Chinese Type 59 main battle tanks, many acquired pre-revolution or captured from Iraq, but international arms embargoes imposed by Western nations and the United Nations restricted access to modern equipment. To address obsolescence and enhance self-reliance, Iranian authorities initiated a domestic modernization program in the early 1990s, designating the upgraded variant as Type 72Z—derived from the Persian solar calendar year 1372 (corresponding to 1993–1994). The program was publicly announced in late 1996 by the Islamic Revolutionary Guard Corps (IRGC), marking a key effort in Iran's defense indigenization strategy amid ongoing sanctions. The upgrade initiative was spearheaded by the Defense Industries Organization (DIO), with primary development at the Shahid Kolah Dooz Industrial Complex, a DIO subsidiary specializing in armored vehicle refurbishment, and supported by the Vehicle Industries Group (VIG). Its core objective was to extend the operational lifespan of approximately 400 surplus T-54/55 and Type 59 tanks through cost-effective enhancements in firepower, mobility, protection, and fire control, transforming second-generation tanks into configurations competitive with contemporary threats without requiring full replacement. This approach leveraged reverse-engineered foreign components, including a Ukrainian-origin V-46-6 diesel engine producing 780 horsepower and Slovenian EFCS-3 fire-control systems, reflecting Iran's pragmatic adaptation of available technology despite limited access to advanced Western systems. Throughout the 2000s, the Type 72Z program progressed into serial production and integration within the Iranian Army's armored brigades, with ongoing refinements to address performance gaps identified in exercises and simulations. By the mid-2000s, the upgrades had been applied to a significant portion of eligible chassis, bolstering Iran's ground forces amid persistent isolation from global arms markets, though exact production figures remain classified. The initiative exemplified Iran's emphasis on incremental improvements over radical redesigns, prioritizing reliability and logistical compatibility with existing fleets.

Recent Production and Export Developments

Iran has maintained ongoing production and upgrade programs for the Type 72Z tank into the 2020s, focusing on enhancing older T-54/55 and Type 59 chassis within its inventory. In August 2020, Iranian defense officials unveiled continued production of the Type 72Z as part of broader army tank modernization efforts, incorporating improvements to firepower, protection, and mobility derived from domestic engineering. These efforts reflect Iran's strategy of sustaining legacy platforms amid sanctions limiting access to newer designs, with upgrades emphasizing cost-effective retrofits over full replacements. The primary export development for the Type 72Z, marketed as Safir-74, occurred in 2006 when Iran supplied an undisclosed number of units and conversion kits to Sudan under a joint production agreement. Sudan subsequently localized production of the variant, designated Al-Zubair I, enabling independent upgrades and maintenance. No major new export contracts have been publicly confirmed since, though the design has supported Iranian-aligned forces in regional conflicts. In Sudan, the Type 72Z has seen active deployment during the ongoing civil war, with verified footage from April 2025 showing Sudanese Armed Forces units operating the tanks against Rapid Support Forces in urban and open terrain engagements. This sustained use underscores the variant's operational viability in asymmetric warfare, bolstered by Iranian technical support and local adaptations, despite vulnerabilities to modern anti-tank threats. Iranian exports of the Type 72Z remain limited to select allies, prioritizing technology transfer over large-scale sales amid international restrictions.

Design and Technical Specifications

Armament and Fire Control Systems

The Type 72Z features a 105 mm rifled main gun, an Iranian derivative of the American M68, installed in place of the original 100 mm D-10T rifled gun found on T-54/55 or Type 59 chassis. This upgrade allows compatibility with Western-style 105 mm ammunition, including armor-piercing fin-stabilized discarding sabot (APFSDS) rounds for improved penetration against modern armored threats. Secondary armament includes a 7.62 mm PKT coaxial machine gun mounted to the left of the main gun and a 12.7 mm DShK anti-aircraft machine gun on the commander's cupola for suppressive fire and defense against low-flying aircraft. The fire control system incorporates the Slovenian Fotona EFCS-3-55 computerized suite, which integrates ballistic computation, gun stabilization, and target tracking to enable accurate first-round hits on stationary and moving targets, including firing while the tank is in motion. This system is paired with an ND-YAG laser rangefinder capable of measuring distances up to 10 km and supports night operations through second-generation image intensifiers. The EFCS-3-55 enhances overall engagement effectiveness by automating lead calculations and compensating for environmental factors like wind and temperature.

Protection and Armor Upgrades

The Type 72Z, also known as Safir-74, retains the original cast steel armor of the T-54/55 and Type 59 base tanks, providing baseline protection equivalent to approximately 200-250 mm against kinetic energy penetrators on the glacis plate. To enhance survivability, Iranian engineers added explosive reactive armor (ERA) packages developed domestically by the Shahid Kolah Dooz Industrial Complex, consisting of about 60 ERA blocks applied to the hull front glacis, upper side skirts, turret front, and turret sides. This ERA configuration features a single layer on most surfaces, with double-layered ERA on critical areas such as the turret for improved resistance against shaped charge warheads and some kinetic threats. The ERA system incorporates a composite layer designed to defeat both chemical energy (CE) munitions like high-explosive anti-tank rounds and kinetic energy (KE) projectiles by disrupting incoming threats through explosive reaction. Additional passive measures include an anti-spall liner installed inside the crew compartment to reduce fragmentation effects from penetrations. These upgrades, implemented as part of Iran's mid-1990s modernization program, aim to extend the operational life of legacy tanks against contemporary anti-tank guided missiles and rocket-propelled grenades prevalent in regional conflicts, though the overall protection remains inferior to third-generation Western or Russian main battle tanks without advanced spaced or multi-layer composites. No verified integration of active protection systems like hard-kill interceptors has been documented for the Type 72Z platform.

Mobility and Powertrain Enhancements

The Type 72Z features a significantly upgraded powertrain derived from the original Type 59 and T-54/55 designs, which originally employed a V-54 series 12-cylinder diesel engine producing approximately 520 horsepower. Iranian modernizations replaced this with a Ukrainian-sourced V-46-6 V-12 liquid-cooled, supercharged diesel engine rated at 780 horsepower, integrated into a modular power pack that includes the engine, SPAT-1200 automatic transmission, cooling systems, brakes, and hydraulics. This upgrade yields a power-to-weight ratio of 19.5 horsepower per ton, enhancing acceleration and overall mobility compared to the baseline tanks' roughly 14-15 hp/ton. The new power pack design unifies internal systems for simplified field repairs and reduced maintenance times, with Iranian sources emphasizing improved reliability in desert conditions prevalent in operational theaters. The SPAT-1200 transmission provides smoother gear shifts and better torque distribution, contributing to a top road speed of approximately 65 km/h, an increase from the original models' 50 km/h limit. Suspension and track components retain the torsion bar system of the progenitors but benefit from the higher engine output, enabling sustained cross-country performance without major redesigns to the chassis. These enhancements extend operational range and maneuverability, though independent assessments note limitations in fuel efficiency due to the engine's Soviet-era roots adapted for heavier loads.

Electronics and Crew Systems

The Type 72Z incorporates the Slovenian Fotona EFCS-3 computerized fire control system, which integrates a digital ballistic computer, automatic and manual gun stabilizers, and supports firing on stationary or moving targets from stationary or moving platforms. This system achieves a hit probability exceeding 80% under optimal conditions by processing inputs from multiple sensors. Key optical and sensing components include a gunner's day sight with 10x magnification and 6° field of view, paired with a second-generation image intensifier night sight offering 7x magnification and the same field of view, enabling target tracking during night engagements without illumination. The Nd:YAG laser rangefinder provides a maximum detection range of 10 km with ±5° accuracy, complemented by sensors for gun elevation, meteorological data via a roof-mounted mast, and powder temperature to refine ballistic solutions for 105 mm ammunition types such as APDS, HEAT, HESH, and APFSDS, as well as the coaxial 7.62 mm machine gun. Crew accommodations retain the standard four-person layout of commander, gunner, loader, and driver inherited from T-54/55 designs, with interfaces including the gunner's control block, commander's panel, and remote displays within the EFCS-3 for situational awareness and target designation. Communication is facilitated by the VRC-222 radio set, interoperable with VRC-122 and R-173 systems, while collective NBC protection and individual night vision devices enhance crew survivability and operational tempo in contested environments.

Variants

Safir-74 Configuration

The Safir-74 represents the Iranian modernization configuration applied specifically to T-54/T-55 main battle tanks, distinguishing it from the Type 72Z upgrade package developed for Type 59 chassis. Initiated by Iran's Defense Industries Organization (DIO) and Vehicle Industries Group in the mid-1990s, following the acquisition of captured Iraqi T-54/55s during the Iran-Iraq War (1980–1988), the program aimed to enhance firepower, mobility, and protection on an estimated 190 such vehicles in Iranian service. Unveiled publicly in 1996 by the Islamic Revolutionary Guard Corps, the Safir-74 ("Messenger 74" in Persian) incorporates locally produced components and imported subsystems to extend the operational life of these Soviet-era designs without full replacement. Key upgrades focus on replacing the original 100 mm rifled gun with a 105 mm L7/M68-derived rifled main gun (designated HM-49L), compatible with Iranian-manufactured ammunition for improved penetration and accuracy at longer ranges. The main armament is supplemented by a coaxial 7.62 mm machine gun and a 12.7 mm DShK anti-aircraft machine gun, with provisions for smoke grenade launchers. Fire control enhancements include the Slovenian EFCS-3 (or EFPC-3-55) system, featuring a laser rangefinder effective to 10,000 m with ±5° accuracy, ballistic computer for firing on the move against stationary or moving targets, and integration of night vision equipment. These modifications enable stabilized aiming and first-hit probability superior to baseline T-54/55 systems, though reliant on foreign-sourced optics and electronics subject to sanctions constraints. Protection features layered defenses beyond the original rolled homogeneous armor (20–203 mm thickness): Iranian-developed explosive reactive armor (ERA) blocks cover 60–65% of the turret front and 70–80% of the hull front, combining composite layers for kinetic energy (KE) and chemical energy (CE) projectile defeat, with a total ERA mass of approximately 1,191 kg (416 kg turret, 281 kg hull front, 494 kg hull sides). Additional welded add-on armor plates augment hull and turret sides, while NBC filtration and automatic fire suppression systems address crew survivability. Mobility improvements stem from a modular powerpack with the Ukrainian-sourced V-46-6 V-12 diesel engine producing 780 hp, paired to an upgraded transmission and torsion bar suspension, yielding a top road speed of 65 km/h and operational range of 510 km. The four-man crew (commander, gunner, loader, driver) benefits from these enhancements, though the loader-operated turret limits firing rates compared to autoloader-equipped contemporaries.

Approximately 400 units across Safir-74 and related programs were converted by the early 2000s, with camouflage schemes varying by theater: desert patterns (sand/black or sand/reddish-brown), northern greens, or multi-tone autumn mixes for operational concealment. While these upgrades demonstrably improve baseline T-54/55 performance against peer threats in regional contexts, independent verification of ERA efficacy and fire control reliability remains limited due to restricted access and Iranian opacity on testing data.

Al-Zubair I Sudanese Variant

The Al-Zubair I is the Sudanese designation for the Type 72Z main battle tank, an Iranian-upgraded variant of the Chinese Type 59 and Soviet T-54/55 series, locally produced under license. Sudan initially acquired an unspecified number of Type 72Z tanks from Iran in 2006, with reports indicating at least ten units delivered that year. These vehicles underwent local assembly and integration into Sudanese forces, distinguishing the Al-Zubair I from subsequent Sudanese Type 59 upgrades designated Al-Zubair II. In Sudanese service, the Al-Zubair I retains the core modernizations of the Iranian Type 72Z, including enhanced fire control systems, improved optics, and potential retrofits for better mobility over the base Type 59 hull. Local production capabilities were established to sustain the fleet, focusing on maintenance and limited upgrades suited to Sudan's operational environment, such as adaptations for desert terrain prevalent in conflict zones. Unlike more extensive Chinese Type 59D variants, the Al-Zubair I emphasizes Iranian-sourced components for armament stabilization and crew ergonomics, though specific Sudanese modifications remain undocumented in open sources. The variant has seen active deployment by the Sudanese Armed Forces in the ongoing civil war since 2023, where footage confirms its use alongside other armored assets against Rapid Support Forces positions. Production under license has enabled Sudan to maintain operational numbers despite attrition, with estimates suggesting dozens in service as of 2025. This reliance on Iranian technology underscores Sudan's strategic partnerships amid arms embargoes, prioritizing cost-effective upgrades over full fleet replacement.

Other Local Adaptations

The Type 72Z upgrade package was applied by Iran to its inventory of Chinese Type 59 main battle tanks, representing a targeted local adaptation distinct from the Safir-74 configuration used on T-54 and T-55 chassis. This variant replaces the Type 59's original 100 mm D-10T rifled gun with an Iranian copy of the 105 mm M68, enabling compatibility with Western ammunition and improving penetration against contemporary armor. Explosive reactive armor tiles are fitted to the glacis plate and turret, providing enhanced protection against shaped-charge warheads, while the fire-control system incorporates a laser rangefinder and ballistic computer for engaging targets at ranges up to 2,000 meters. Mobility enhancements include potential retrofits to the powerpack, such as auxiliary power units or transmission tweaks derived from Iranian engineering efforts to address the Type 59's underpowered V-12 diesel engine, though exact specifications for this sub-variant are not publicly detailed. These modifications, initiated in the mid-1990s amid sanctions limiting access to modern platforms, extended the operational viability of approximately 200 Type 59s in Iranian service without altering the core hull layout. Sudanese acquisitions of Type 72Z kits have reportedly incorporated minor local adjustments for desert operations, but such changes remain unverified beyond standard Iranian exports received around 2006.

Operators and Deployment

State Operators

The Islamic Republic of Iran serves as the primary state operator of the Type 72Z tank, having developed the upgrade through its Defense Industries Organization to modernize legacy T-54/55 and Type 59 main battle tanks. These Safir-74 configured vehicles equip units of the Iranian Army, providing enhanced firepower and protection relative to unmodified Cold War-era chassis, though exact inventory numbers remain classified due to Iran's opaque military reporting. The Republic of Sudan is the sole confirmed foreign state operator, procuring Type 72Z tanks from Iran beginning in 2006 to augment its armored forces amid limited access to advanced Western or Russian systems. Locally adapted as the Al-Zubair I variant, Sudanese examples feature minor modifications suited to regional logistics and have been documented in active service during the civil war that erupted in April 2023 between the Sudanese Armed Forces and Rapid Support Forces. Deployments include urban and open-terrain engagements around Khartoum, where the tanks' 105mm guns and reactive armor have been employed against paramilitary threats, though attrition from drone strikes and anti-tank weapons has reduced operational availability.

Non-State and Proxy Operators

The Rapid Support Forces (RSF), a paramilitary group formerly integrated into Sudan's security apparatus but now opposing the Sudanese Armed Forces (SAF) in the civil war that erupted on April 15, 2023, have incorporated captured Al-Zubair I main battle tanks into their inventory. The Al-Zubair I represents Sudan's locally assembled and adapted version of the Iranian Type 72Z, featuring upgrades such as a new fire control system and 105 mm gun originally derived from T-54/55 chassis. RSF forces seized quantities of these tanks from SAF depots early in the conflict, including at Jabal Awliya Airbase southwest of Khartoum, as evidenced by group-released footage from April 2023 showing stored Al-Zubair I vehicles marked with Sudanese military insignia. Such acquisitions supplemented the RSF's primarily mobile, light-vehicle doctrine, enabling limited heavy armor operations amid urban and rural engagements, though operational numbers remain unverified and likely modest due to maintenance challenges inherent to the aging base design. No confirmed deployments of the Type 72Z by Iranian-aligned proxy groups, such as Hezbollah in Lebanon or Houthi forces in Yemen, have been reported, despite Iran's provision of upgraded armor to state partners like Sudan since 2006. Hezbollah maintains legacy T-54/55 stocks but lacks evidence of Iranian Type 72Z-specific modernizations in its arsenal. Similarly, Houthi operations emphasize asymmetric warfare with drones and missiles over conventional tanks, with no documented receipt or use of Type 72Z variants. In Iraq, Popular Mobilization Forces units operate assorted Soviet-era T-55s and T-72s supplied or refurbished by Iran, but these do not include the distinct Type 72Z configuration. The absence of proliferation to proxies underscores the Type 72Z's primary role in state inventories, limited by production constraints and Iran's strategic prioritization of missile and drone exports for deniable proxy support.

Operational History and Performance

Service in Iranian Forces

The Type 72Z, designated T-72Z or Safir-74, entered service with the Iranian Army in 1996 as part of a domestic upgrade initiative targeting legacy T-54/T-55 and Type 59 main battle tanks. Developed by the Defense Industries Organization's Vehicle Industries Group, the program replaced the original 100 mm rifled guns with 105 mm M68-style weapons, integrated improved fire control systems, and added composite armor enhancements to extend the viability of these Cold War-era platforms. Many of the base tanks originated from captures during the Iran-Iraq War (1980–1988), with estimates suggesting up to 190 T-54/T-55 series vehicles potentially upgraded. Within the Iranian Ground Forces (Artesh), Type 72Z tanks primarily fulfill reserve, training, and territorial defense roles, complementing primary armored assets like the T-72S and indigenous Zulfiqar variants. Production and integration efforts continued into the 2000s, with the vehicles appearing in military exercises and parades, though detailed records of frontline deployments in Iran are scarce. As of recent assessments, upgraded Type 72Z units remain in inventory, supporting Iran's strategy of maximizing existing hardware amid sanctions limiting access to newer imports.

Combat Use in Sudan (2023–Present)

The Type 72Z main battle tank, locally designated Al-Zubair I in Sudanese service, has been employed by the Sudanese Armed Forces (SAF) throughout the civil war against the Rapid Support Forces (RSF), which commenced on 15 April 2023. Originally acquired from Iran in 2006 with subsequent licensed production in Sudan, these upgraded T-54/55 derivatives serve as one of the SAF's principal heavy armored units, offering enhanced firepower through their 105mm rifled guns and explosive reactive armor for frontline engagements. Deployment of the Al-Zubair I has persisted amid intense urban and semi-urban combat, particularly in efforts to regain control of Khartoum and surrounding areas from RSF positions. Footage from April 2025 documents SAF Type 72Z tanks advancing with infantry support, utilizing Chinese-made DJI drones for reconnaissance and night-vision equipment for operations in contested zones, highlighting their integration into combined arms tactics against RSF's more mobile forces. Despite these upgrades, the tanks have encountered vulnerabilities in the conflict's asymmetric environment, where RSF fighters employ man-portable anti-tank guided missiles, improvised explosive devices, and loitering munitions to target SAF armor. Multiple instances of Al-Zubair I losses, including destructions and captures by RSF units, have been reported, underscoring the challenges of operating legacy-based platforms against agile paramilitary tactics in prolonged urban warfare. Sudan maintains approximately 50 such tanks, though attrition has reduced operational numbers since 2023.

Deployment by Proxies in Regional Conflicts

The Type 72Z tank, despite Iran's strategy of arming allied militias across the Middle East and Africa, has not been documented in the inventory or combat use of non-state proxy groups such as Hezbollah, Houthi forces, or Popular Mobilization Units (PMU) militias in Iraq and Syria. Iranian transfers to these actors emphasize portable, asymmetric systems like short-range rockets, drones, and anti-tank guided missiles, which align with guerrilla tactics and minimize logistical demands in denied environments, rather than crew-served heavy armor vulnerable to air strikes and requiring extensive maintenance. Reports of Iranian upgraded T-55 variants reaching proxies remain unverified and contradicted by open-source visual confirmations, which show proxy forces relying on captured or legacy Soviet-era tanks like T-55s and T-62s without the Type 72Z's distinctive turret and fire-control upgrades. In Yemen's civil war, Houthi armored operations draw from seized Yemeni Army stocks predating Iranian involvement, with no evidence of Safir-74 kits or equivalent modernizations. Similarly, in Syria and Iraq, Iranian-backed groups operate older T-54/55 hulls sourced locally or from regime allies, but lack the 105mm gun and reactive armor packages characteristic of the Type 72Z. This pattern reflects causal constraints: proxies prioritize deniability and mobility over platforms needing trained crews and supply chains, which Iran reserves for state partners like Sudan, where over 200 Type 72Z units bolster conventional Sudanese Armed Forces operations against Rapid Support Forces since April 2023. Proliferation risks persist, however, given Iran's history of reverse-engineering and kit exports, though no empirical data confirms Type 72Z fielding by non-state actors as of late 2025.

Evaluation and Controversies

Technical Strengths and Improvements

The Type 72Z, also designated Safir-74, incorporates substantial enhancements to the original T-54/55 chassis, primarily focusing on powertrain modernization and firepower upgrades to extend operational viability. The most notable improvement is the replacement of the legacy engine with a Ukrainian-sourced V-46-6 V-12 liquid-cooled diesel engine delivering 780 horsepower, integrated into a modular power pack that facilitates maintenance and reliability in field conditions. This upgrade boosts the power-to-weight ratio from approximately 14-15 hp/ton in baseline T-55 models to around 21 hp/ton at a combat weight of 36 tons, enabling a maximum road speed of 65 km/h and an extended operational range of 510 km. Accompanying this are refinements to the transmission, including a new gearbox, hydraulic steering, braking systems, and cooling apparatus, which collectively improve maneuverability and reduce mechanical failures common in aging Soviet-era designs. Fire control and armament systems represent another core strength, transforming the tank's engagement capabilities. The original 100 mm D-10T gun is supplanted by a 105 mm HM-49L smoothbore main gun, compatible with advanced kinetic energy penetrators and high-explosive rounds, supported by a coaxial 7.62 mm machine gun and a 12.7 mm anti-aircraft machine gun. A Slovenian EFCS-3 fire control system, incorporating a laser rangefinder with a maximum detection range of 10,000 meters and accuracy within ±5 meters, enables precise targeting in day or night conditions. Automatic and manual gun stabilization further allows effective firing while moving, a marked advancement over the unstabilized turret of predecessor models, thereby enhancing first-strike potential in dynamic combat scenarios. Protective measures have been incrementally bolstered, particularly through the addition of explosive reactive armor (ERA) kits applied to the frontal hull and turret sides around the early 2000s, alongside armored side skirts to mitigate shaped-charge threats. These modifications, combined with the inherent low silhouette and robust base armor of the T-55 hull, provide improved survivability against anti-tank guided missiles and rocket-propelled grenades prevalent in asymmetric warfare. Overall, these upgrades—effected by Iran's Defense Industries Organization starting in the mid-1990s—demonstrate resourceful adaptation of obsolete platforms to meet contemporary tactical demands, particularly in resource-constrained environments where full replacement fleets are infeasible.

Limitations and Vulnerabilities

The Type 72Z retains the fundamentally thin armor layout of its T-54/55 and Type 59 antecedents, with the hull glacis providing only about 200 mm of line-of-sight equivalent protection against kinetic energy penetrators after sloping, rendering it highly susceptible to modern APFSDS rounds from 125 mm guns that routinely exceed 600 mm penetration at combat ranges. Side armor, typically 80 mm thick on the original chassis, offers negligible resistance to ATGMs or even 30 mm autocannon fire, exposing the vehicle to flanking threats common in asymmetric conflicts. While add-on armor packages, including appliqué steel and possible ERA elements totaling around 1,200 kg, are claimed to enhance frontal protection, their efficacy against tandem-warhead ATGMs like the Kornet remains unverified in independent testing and likely insufficient given the base vehicle's structural limits. Ammunition stowage vulnerabilities persist from the legacy design, with ready rounds stored in the fighting compartment below the turret ring, increasing the likelihood of catastrophic secondary explosions upon hull penetration—a flaw exacerbated in urban or drone-heavy environments where precise top or side hits are feasible. The upgraded 125 mm smoothbore gun improves firepower over the original 100 mm, but the autoloader mechanism, adapted from older Soviet principles, limits rate of fire to 6-8 rounds per minute under optimal conditions and poses crew safety risks from propellant handling. Ergonomic constraints of the cramped hull, inherited from 1950s engineering, hinder sustained operations, with limited space restricting advanced electronics integration and crew comfort during prolonged engagements. In Sudanese service since approximately 2006, Type 72Z variants (locally termed Al-Zubair I) have been committed to the ongoing civil war against Rapid Support Forces equipped with portable ATGMs, loitering munitions, and commercial drones, where broader Sudanese armored losses—documented at over 100 tanks including T-55 derivatives by mid-2023—underscore vulnerabilities to non-state actors exploiting mobility and precision strikes over massed armor. Iranian upgrades, constrained by sanctions-induced material shortages, have drawn skepticism regarding long-term reliability, with reports of inconsistent optics and fire control performance in proxy deployments highlighting gaps between claimed capabilities and real-world resilience.

Strategic Impact and Proliferation Concerns

The Type 72Z upgrade package enables Iran to extend the operational life of its legacy T-54/T-55 and Type 59 tank stocks, which constitute a substantial element of the Iranian Army's armored brigades, by incorporating improved fire control systems, optics, and potentially a more potent 105mm gun, thereby maintaining a credible deterrent posture amid persistent sanctions that restrict procurement of contemporary platforms. This approach aligns with Iran's emphasis on indigenous modifications to circumvent import dependencies, allowing quantity and familiarity to offset qualitative gaps against adversaries equipped with advanced Western or Russian systems. In operational terms, the tank's deployment bolsters defensive depth in Iran's doctrine of layered attrition warfare, particularly along borders vulnerable to expeditionary threats, though its vulnerabilities to precision-guided munitions limit offensive potential. For recipient states like Sudan, the Type 72Z—locally designated Al-Zubair 1—delivers a cost-effective means to rehabilitate aging fleets, with acquisitions dating to 2006 providing the Sudanese Armed Forces (SAF) with roughly a dozen upgraded units amid the civil war that erupted in April 2023. These tanks have been observed in SAF offensives around Khartoum and other fronts, offering superior gunnery accuracy over unmodified T-55s and contributing to localized breakthroughs against the Rapid Support Forces' (RSF) lighter, more maneuverable vehicles. However, battlefield losses, exacerbated by drone strikes and anti-tank guided missiles, underscore the upgrade's inability to fully mitigate the platform's obsolescent chassis, mobility constraints in urban and desert environments, and thin armor, resulting in a net strategic attrition rather than decisive superiority. Proliferation of the Type 72Z raises apprehensions over Iran's expansion of military-industrial ties beyond the Middle East, with exports to Sudan exemplifying Tehran's strategy to cultivate African footholds for resource access and proxy leverage, potentially destabilizing the Horn of Africa and Red Sea shipping lanes critical to global trade. Although the UN Security Council's conventional arms embargo on Iran lapsed in October 2020 under Resolution 2231, transfers persist under U.S. secondary sanctions prohibiting dealings with Iranian defense entities like the Defense Industries Organization, which oversees the upgrades, prompting accusations of embargo circumvention via third-party routing. In Sudan, where a partial UN arms embargo applies to Darfur-linked flows since 2004, Iranian-supplied armor has fueled the SAF-RSF stalemate, with documented use prolonging urban combat and humanitarian crises, as both factions acquire external arms despite international calls for restraint. Broader concerns include the risk of technology leakage from reverse-engineering the Type 72Z's Iranian-sourced components, such as fire control electronics, enabling recipient states or non-state actors to indigenize similar enhancements and erode export controls. While no verified diversions to proxies like Hezbollah or Houthis have occurred, the tank's affordability—estimated under $1 million per unit versus multi-millions for peers—facilitates diffusion to budget-limited militaries, amplifying Iran's soft power in proxy conflicts and complicating multinational stabilization efforts in theaters like Yemen or Syria. Analysts note that such proliferation, though not transformative due to the base tank's dated ergonomics and sensor limitations, nonetheless sustains low-intensity armored operations, indirectly challenging U.S.-aligned coalitions by diluting focus on higher-end threats.
