Richard Stiedemann II 26 Jun 2025

As the geopolitical landscape of Southwestern Asia continues to evolve, understanding the capabilities of regional military forces becomes increasingly vital. One such force, often shrouded in a mix of speculation and strategic secrecy, is the Islamic Republic of Iran Air Force (IRIAF). This article aims to provide a comprehensive look into the projected Iran Air Force aircraft inventory 2025, analyzing its current composition, the impact of decades of sanctions, and potential future acquisitions.

Iran, a mountainous, arid, and ethnically diverse country, holds a strategically significant position between the Caspian Sea in the north and the Persian Gulf and the Gulf of Oman in the south. As the heart of the Persian Empire of antiquity, Iran has long played an important role in the region. Its military, particularly its air force, reflects a unique blend of inherited legacy equipment, domestic innovation, and strategic partnerships forged under the pressure of international sanctions. By 2025, the IRIAF is expected to remain a force shaped by these enduring realities, presenting a complex picture of both limitations and surprising resilience.

The Strategic Landscape: Iran's Geopolitical Position

Iran is officially an Islamic Republic, a cradle of civilization, and a nation with a rich and distinctive cultural and social continuity dating back millennia. Tehran, the nation's capital, largest city, and financial center, serves as the nerve center for its strategic planning. Geographically, Iran's mountainous and arid terrain, combined with its extensive coastlines on the Persian Gulf and Caspian Sea, presents both defensive advantages and complex logistical challenges. This unique geography, coupled with its historical role as the heart of the Persian Empire, dictates a need for a robust, albeit often constrained, military posture.

The regional dynamics are highly volatile. News reports frequently highlight tensions, such as "Iran reports 935 killed in conflict with Israel, with Israel reporting 28 deaths from retaliatory strikes," underscoring the precarious security environment. The "US struck several key Iranian nuclear facilities early Sunday, including Fordow, Natanz and Isfahan," demonstrating the direct implications of geopolitical friction on Iran's strategic assets. In this context, the Iran Air Force aircraft inventory 2025 is not merely a list of planes; it is a critical component of Iran's deterrence strategy and its capacity to project power or defend its sovereignty in a complex neighborhood.

Decades of Sanctions: Shaping Iran's Air Power

The most defining factor in the evolution of the Iran Air Force has been the enduring international sanctions regime. Following the 1979 revolution, Iran lost access to its primary Western suppliers, particularly the United States, which had previously equipped the Imperial Iranian Air Force with some of the most advanced aircraft of its time. This abrupt cutoff forced Iran into an unprecedented era of self-reliance, improvisation, and reliance on a limited number of non-Western partners.

The "Data Kalimat" subtly hints at this prolonged tension, mentioning "President Donald Trump said early Monday he is not offering Iran anything despite suggesting new nuclear talks with Tehran." Such statements reflect the continuous pressure and lack of open channels for military procurement from traditional Western sources. For decades, Iran has struggled to acquire spare parts, maintenance support, and new generation aircraft, severely limiting the modernization of its air fleet. This has led to an air force largely composed of aging platforms, many of which date back to the 1970s. However, it has also spurred significant domestic engineering efforts, as Iranian technicians and engineers have become adept at reverse-engineering, repairing, and even producing components for their existing fleet, a testament to their ingenuity under duress. This unique history means the Iran Air Force aircraft inventory 2025 will still bear the hallmarks of these historical constraints.

The Current Backbone: Aging but Resilient Fleet

By 2025, the core of the Iran Air Force's combat strength is still expected to be its legacy aircraft, many of which were acquired before the 1979 revolution or during the immediate post-revolutionary period from the Soviet Union and China. Despite their age, Iranian technicians have managed to keep a significant portion of these aircraft operational through ingenious maintenance, cannibalization, and domestic production of parts.

Fighter Jets: The Legacy Fleet

Grumman F-14 Tomcat: Iran is the only country outside the United States to have operated the F-14. Acquired in the 1970s, these interceptors remain the most capable air superiority fighters in the IRIAF inventory. Despite their age, Iran has invested heavily in maintaining and upgrading them, reportedly equipping them with domestically produced missiles like the Fakour-90, a reverse-engineered AIM-54 Phoenix. While their numbers are dwindling, a core fleet is expected to remain operational in 2025.
McDonnell Douglas F-4 Phantom II: The F-4 serves as the workhorse of the IRIAF, performing multiple roles including ground attack, reconnaissance, and air defense. Iran operates several variants (D, E, and RF-4E). Their versatility and robust design have allowed them to remain relevant, though their combat effectiveness against modern adversaries is limited.
Northrop F-5 Freedom Fighter/Tiger II: These lighter, more agile fighters are used for both air-to-air and air-to-ground missions. Iran has extensively modified and reverse-engineered the F-5, leading to the development of indigenous aircraft like the Saeqeh and Kowsar, which are based on the F-5 airframe.
Mikoyan MiG-29 Fulcrum: Acquired from the Soviet Union in the early 1990s, these are Iran's most modern Russian-origin fighters. Primarily used for air defense, they provide a more contemporary air-to-air capability compared to the older Western jets.
Dassault Mirage F1: A small number of these French-made fighters were flown to Iran by Iraqi pilots during the 1991 Gulf War and subsequently impounded. They have been integrated into the IRIAF, adding another layer of diversity to its inventory.

Bombers and Attack Aircraft

Sukhoi Su-24 Fencer: These supersonic, swing-wing attack aircraft, also acquired from the Soviet Union, represent Iran's most potent long-range strike capability. They are capable of carrying a significant payload of bombs and missiles.
Chengdu J-7/F-7 Airguard: Chinese-made variants of the MiG-21, these light fighters are primarily used for air defense and ground attack roles. They are less sophisticated but provide a numerically significant component to the Iran Air Force aircraft inventory 2025.

Domestic Endeavors: Self-Sufficiency and Innovation

Faced with persistent sanctions, Iran has prioritized self-sufficiency in its defense industry. This has led to significant investment in reverse-engineering, maintenance, and domestic production of military hardware, including aircraft. While often based on older designs, these indigenous projects represent a crucial aspect of Iran's ability to sustain its air force.

HESA Saeqeh: This is a twin-tail variant of the F-5 Freedom Fighter, developed by Iran's Aircraft Manufacturing Industries Company (HESA). It first flew in 2004 and is intended to serve as a multirole fighter. While its capabilities are likely limited compared to modern fourth-generation aircraft, it signifies Iran's capacity to modify and produce its own combat jets.
HESA Kowsar: Unveiled in 2018, the Kowsar is another domestically manufactured jet fighter, also based on the F-5 platform. It is described as a fourth-generation fighter, though this classification is debated by international experts given its origins. The Kowsar aims to bolster Iran's fighter fleet with locally produced aircraft, reducing reliance on foreign suppliers.
Simorgh: This is a locally modified and upgraded version of the F-5, primarily used for training and light attack roles.
Training Aircraft: Iran has also developed indigenous training aircraft like the Parastoo and Tazarv, crucial for pilot training and maintaining readiness within the IRIAF.

These domestic efforts, while not producing cutting-edge stealth fighters, are vital for maintaining operational readiness and demonstrating Iran's commitment to overcoming external pressures. They ensure that the Iran Air Force aircraft inventory 2025 includes at least some newly built, albeit older-generation, platforms.

Future Prospects: Potential Acquisitions and Upgrades

The lifting of the UN arms embargo on Iran in October 2020 opened new avenues for military procurement, although the United States maintains its own sanctions. This development has sparked considerable speculation about Iran's potential for significant upgrades to its air force. By 2025, any major changes to the Iran Air Force aircraft inventory 2025 will largely depend on its ability to secure new deals and overcome financial and logistical hurdles.

The Russian Connection

Russia is widely considered the most likely source for new Iranian military aircraft. Reports have consistently indicated Iran's interest in acquiring advanced Russian fighters to modernize its aging fleet. Potential acquisitions include:

Sukhoi Su-35 Flanker-E: This highly capable 4++ generation multirole fighter is a prime candidate for Iran's modernization efforts. Acquiring a squadron or two of Su-35s would significantly enhance Iran's air superiority and strike capabilities, providing a qualitative leap over its current inventory. Deliveries, if confirmed, could potentially begin before or by 2025, although the full integration and operational readiness would take time.
Yakovlev Yak-130 Mitten: This advanced jet trainer and light attack aircraft would be invaluable for training Iranian pilots on modern systems and could also serve as a limited combat platform. Iran reportedly received its first Yak-130s in 2023, signaling a concrete step towards modernizing its training fleet and potentially paving the way for more advanced acquisitions.
Other Russian Aircraft: While less certain, Iran might also seek other Russian platforms such as additional MiG-29s, Su-30s, or even transport aircraft and helicopters, depending on its strategic needs and financial capacity.

Beyond 2025: Long-Term Vision

Beyond 2025, Iran's long-term vision for its air force likely includes continued domestic development and a gradual shift towards more modern platforms. The integration of new Russian aircraft, if it materializes on a significant scale, would require substantial investment in pilot training, maintenance infrastructure, and logistics. This transition would be a multi-year process, meaning that even with new acquisitions, the legacy fleet will likely remain a critical component of the Iran Air Force aircraft inventory 2025 and beyond.

Iran's focus will also likely remain on enhancing its existing platforms with modern avionics, electronic warfare systems, and precision-guided munitions, whether domestically produced or acquired from partners. This approach of incremental upgrades to older airframes, combined with strategic new purchases, reflects a pragmatic strategy to improve capabilities within its constraints.

Helicopter and Transport Fleets: Essential Support

Beyond combat aircraft, the Iran Air Force aircraft inventory 2025 also includes a diverse range of helicopters and transport aircraft, crucial for logistical support, troop movement, search and rescue, and special operations. These fleets have faced similar challenges to the combat jets in terms of maintenance and spare parts due to sanctions.

Helicopters: The IRIAF operates a mix of U.S.-made (e.g., Bell 214, CH-47 Chinook) and Russian-made (e.g., Mi-17) helicopters. Many of these are maintained through extensive domestic overhaul programs. Iran has also produced its own versions, such as the Shabaviz 2-75 and Toufan, based on Bell designs.
Transport Aircraft: The transport fleet includes older U.S.-made aircraft like the C-130 Hercules, as well as Russian-made Il-76s and An-74s. These aircraft are vital for strategic airlift and humanitarian missions, but their operational readiness is a constant challenge.
Unmanned Aerial Vehicles (UAVs): While not traditionally part of the "aircraft inventory" in the same way as manned aircraft, Iran's significant advancements in UAV technology cannot be overlooked. By 2025, UAVs will play an increasingly integral role in reconnaissance, surveillance, and strike missions, complementing the manned air force and potentially compensating for some of its limitations. Iran's drone capabilities are a key component of its asymmetric warfare strategy.

Air Defense Systems: Complementing Air Power

An air force's effectiveness is intrinsically linked to its air defense capabilities. Iran has invested heavily in building a layered air defense network to protect its airspace and critical facilities, especially given the threats implied by events like the "US struck several key Iranian nuclear facilities." This network complements the manned aircraft inventory and is crucial for Iran's overall aerial deterrence.

S-300 PMU2: Acquired from Russia, this advanced long-range surface-to-air missile (SAM) system provides a formidable defensive umbrella over key strategic sites. It significantly enhances Iran's ability to detect and engage incoming threats.
Bavar-373: This is Iran's domestically developed long-range SAM system, often compared to the S-300. Its development underscores Iran's commitment to self-reliance in critical defense technologies. The Bavar-373 is a crucial component of Iran's layered air defense strategy.
Sayyad Series: A family of domestically produced SAMs (Sayyad-2, Sayyad-3, Sayyad-4) designed for various ranges and altitudes, integrated into different air defense systems.
Older Systems: Iran continues to operate older, but still relevant, systems like the HQ-2 (Chinese variant of S-75), Rapier, and various domestically upgraded systems.

This robust air defense network aims to deter potential aggressors and provide cover for the IRIAF's operational areas. The interplay between Iran's manned aircraft and its ground-based air defenses is a critical aspect of its overall air power strategy by 2025.

Challenges and Limitations for 2025

Despite its resilience and potential for new acquisitions, the Iran Air Force aircraft inventory 2025 will still face significant challenges:

Aging Fleet: The fundamental issue remains the age of the majority of its combat aircraft.
