Iran's Air Power 2025: What Fighter Jets Guard The Skies?

In the intricate tapestry of global geopolitics, the strength and modernization of a nation's military air power often serve as a critical indicator of its strategic posture and defensive capabilities. For a country like Iran, situated on the Iranian plateau, a geological formation in western and central Asia, and at the heart of the Persian Empire of antiquity, its air force is not merely a collection of aircraft but a reflection of decades of geopolitical isolation, indigenous innovation, and strategic adaptation. As we look towards 2025, understanding the Iranian Air Force fighter jets inventory becomes crucial, offering insights into its current challenges, potential advancements, and the broader implications for regional stability.

Iran, a mountainous, arid, and ethnically diverse country of southwestern Asia, has long played an important role in the region. Its rich history, dating back to 4000 BC with some of the world's oldest continuous major civilizations, has shaped a unique path for its defense forces. However, in recent decades, particularly since the 1979 Islamic Revolution, which changed the Iranian government to an Islamic Republic, Iran's military, including its air force, has operated under severe international sanctions. These restrictions have profoundly impacted its ability to acquire modern military hardware, forcing it to rely on a mix of aging Western-supplied jets, Soviet-era aircraft, and increasingly, its own domestically developed platforms.

The Geopolitical Landscape Shaping Iran's Air Force

Iran's strategic importance cannot be overstated. As the heart of the Persian Empire of antiquity, Iran has long played an important role in the region as a major power. Its geographical position, with most of the country situated on the Iranian plateau, except for the coastal regions at the Caspian Sea and the Khuzestan province in the southwest, gives it significant strategic depth. This position, however, also places it at the nexus of regional rivalries and global power dynamics. The "Data Kalimat" highlights the recent escalation, noting that "The US has entered Israel's war on Iran after attacking three nuclear sites," and the profound impact this has on the populace, with people in Iran voicing "fear, sorrow and grief after waking up to the news of strikes on the country’s nuclear facilities." The tragic loss of "Hundreds of thousands mourn top Iranian military commanders and scientists killed in Israeli strikes" underscores the volatile environment in which the Iranian Air Force operates. This intense geopolitical pressure, coupled with the long-standing international sanctions, has profoundly shaped Iran's military doctrine and its approach to maintaining and modernizing its air force. The need for self-reliance has become paramount, leading to a focus on indigenous defense industries and unconventional warfare capabilities. The perception of external threats, particularly from the United States and Israel, drives Iran's defense planning, making the state of its Iranian Air Force fighter jets inventory a matter of national security and strategic deterrence.

A Legacy of Sanctions: Impact on Iranian Air Power

The 1979 Islamic Revolution marked a pivotal moment for Iran. Soon afterwards, the Iranian Students Movement (Tahkim Vahdat), with the backing of the new government, took actions that led to severe international isolation. The seizure of the US Embassy personnel on November 4, 1979, labeling the embassy a "den of spies," initiated a cascade of sanctions that have crippled Iran's access to advanced military technology. Before the revolution, Iran possessed one of the most advanced air forces in the region, equipped primarily with American-made aircraft like the F-14 Tomcat, F-4 Phantom II, and F-5 Freedom Fighter. These aircraft were procured during the era of the Shah, who maintained close ties with the West. However, the imposition of an arms embargo and various economic sanctions meant that Iran could no longer acquire spare parts, maintenance support, or new aircraft from Western suppliers. This forced the Iranian Air Force (IRIAF) into an unprecedented situation: maintaining a sophisticated fleet without manufacturer support. This challenge has led to remarkable ingenuity in reverse engineering, domestic production of components, and an extensive network for acquiring parts through unofficial channels. Despite these efforts, the sanctions have undeniably limited the modernization and operational readiness of the Iranian Air Force fighter jets inventory, leaving it largely reliant on aging platforms.

Current Inventory: The Backbone of the IRIAF

As of late 2024, and projected into 2025, the core of the Iranian Air Force fighter jets inventory remains a diverse, albeit aging, collection of aircraft. This inventory is a testament to Iran's resilience in the face of prolonged sanctions and its ability to keep highly complex machines operational for decades beyond their intended service life. The fleet comprises a mix of American, Soviet/Russian, and Chinese-origin aircraft, supplemented by a growing number of indigenously developed platforms.

American-Origin Aircraft: Aging but Enduring

The most iconic and capable aircraft in Iran's inventory are its American-made jets, acquired before the 1979 revolution.
  • Grumman F-14A Tomcat: Iran is the only country outside the United States to have operated the F-14. Approximately 40-45 F-14s were delivered before the revolution. Despite the lack of official spare parts for over four decades, Iran has managed to keep a significant number of these interceptors operational. Their powerful AWG-9 radar and long-range AIM-54 Phoenix missiles (some reportedly reverse-engineered) make them a formidable asset, primarily for air defense. However, their operational numbers are likely dwindling, with perhaps only a dozen or so truly airworthy by 2025.
  • McDonnell Douglas F-4 Phantom II: Iran received a large number of F-4D, F-4E, and RF-4E variants. These multi-role fighters have been the workhorse of the IRIAF for decades, performing ground attack, reconnaissance, and air-to-air missions. While robust, their technology is severely outdated. Iran has reportedly made significant efforts to reverse-engineer parts and upgrade some systems, but their combat effectiveness against modern adversaries is limited. Hundreds were delivered, but the operational fleet in 2025 is likely in the low dozens.
  • Northrop F-5 Freedom Fighter/Tiger II: Iran also acquired a substantial fleet of F-5E/F aircraft. These lighter, more agile fighters are used for air defense, ground attack, and as a basis for Iran's indigenous fighter development programs (like the Saeqeh and Kowsar). Many have been heavily modified or cannibalized for parts. The operational numbers are difficult to ascertain, but they likely constitute a significant portion of the active fighter fleet.

Soviet/Russian-Origin Aircraft: A Mix of Capabilities

Following the Iran-Iraq War and a shift in geopolitical alignments, Iran turned to the Soviet Union and later Russia for military hardware.
  • Mikoyan MiG-29 Fulcrum: Iran acquired MiG-29A/UB multi-role fighters from the Soviet Union in the early 1990s. These aircraft provide a more modern air-to-air capability than the older American jets, though they are still first-generation post-Cold War designs. Iran operates a relatively small fleet, likely around 20-30 aircraft. Their maintenance and upgrade path depends heavily on Russian support, which has been inconsistent due to various pressures.
  • Sukhoi Su-24 Fencer: A number of Su-24MK strike aircraft were also acquired, providing Iran with a dedicated long-range interdiction and strike capability. These variable-geometry wing bombers are potent for ground attack but are aging and require significant maintenance. Iran's operational fleet is estimated to be around 20-25 aircraft.
  • Chengdu J-7/F-7 Airguard: Iran also operates a small number of Chinese-made J-7s, which are essentially reverse-engineered MiG-21s. These are basic, lightweight interceptors primarily used for air defense and training. Their numbers are limited, likely fewer than 20.
  • Dassault Mirage F1EQ/BQ: A unique addition to Iran's inventory came from Iraqi aircraft that sought refuge in Iran during the 1991 Gulf War. Iran absorbed these aircraft into its air force, including a small number of Mirage F1EQ/BQ fighters. While a capable platform in its time, their integration into the IRIAF's logistics chain has been challenging, and their operational status is questionable.

Indigenous Efforts: Iran's Self-Reliance in Aviation

Faced with persistent sanctions, Iran has invested heavily in its domestic defense industry, including aviation. This drive for self-reliance is a direct consequence of its geopolitical isolation and the necessity to maintain its Iranian Air Force fighter jets inventory. While often criticized for being reverse-engineered or re-branded older designs, these efforts demonstrate Iran's determination to overcome technological barriers.
  • HESA Saeqeh: This is an Iranian-built fighter, first unveiled in 2007. It is widely believed to be a reverse-engineered and modified version of the American F-5E, featuring twin vertical stabilizers. While presented as a new generation fighter, its capabilities are likely comparable to, or slightly improved upon, the F-5. Its production numbers are limited, and it serves more as a symbol of Iran's self-sufficiency than a mass-produced frontline fighter.
  • HESA Kowsar: Unveiled in 2018, the Kowsar is another domestically manufactured fighter jet, also based on the F-5 platform. It is described as an advanced jet trainer with combat capabilities, potentially incorporating more modern avionics. Like the Saeqeh, its operational numbers are small, and its true combat effectiveness against modern threats is debatable.
  • Simorgh and Azarakhsh: These are earlier Iranian projects, also based on the F-5. The Simorgh was essentially an F-5 converted into a two-seat trainer, while the Azarakhsh was an attempt at a single-seat fighter. These projects highlight Iran's long-standing efforts to maintain and modify its F-5 fleet.
These indigenous programs, while not producing cutting-edge stealth fighters, are crucial for Iran. They allow the IRIAF to maintain a baseline level of operational capability, train new pilots, and keep its aerospace engineers employed and skilled. More importantly, they reduce dependence on external suppliers, a vital strategic imperative for a nation under constant pressure.

Potential Acquisitions for 2025: A Glimmer of Modernization

The lifting of the UN arms embargo in October 2020 opened a window for Iran to potentially acquire modern military hardware from countries like Russia and China. This has been a significant point of speculation regarding the future of the Iranian Air Force fighter jets inventory.

The Su-35: A Game Changer?

The most anticipated potential acquisition for Iran is the Russian Sukhoi Su-35 'Flanker-E' multi-role fighter. Reports of Iran's interest in, and even potential acquisition of, these advanced 4++ generation jets have been circulating for years.
  • Capabilities: The Su-35 would represent a monumental leap in capability for the IRIAF. It boasts super-maneuverability, advanced avionics, powerful radar, and a wide array of modern air-to-air and air-to-ground weaponry. Its integration would significantly enhance Iran's air defense and offensive strike capabilities, potentially altering the regional air power balance.
  • Challenges: Despite the reported interest, actual delivery has been slow. Factors include Russia's own military needs (especially given the conflict in Ukraine), financial arrangements, and potential pressure from other global powers. Even if a deal is finalized, integrating and maintaining such a sophisticated platform would require extensive training, infrastructure upgrades, and a reliable supply chain for spare parts – challenges that Iran has historically struggled with. By 2025, it's possible a small number of Su-35s could be delivered, but a large-scale integration is unlikely.

Other Potential Partners and Platforms

While the Su-35 remains the primary focus, Iran might also explore other options:
  • Chinese Aircraft: China has emerged as a major arms exporter, and its J-10C 'Vigorous Dragon' fighter could be another option for Iran. The J-10C is a modern 4.5 generation fighter with active electronically scanned array (AESA) radar and advanced weaponry. However, China's willingness to sell such advanced platforms to Iran, given its complex relationship with the West, remains a variable.
  • Maintenance and Upgrades for Existing Fleet: Beyond new acquisitions, Iran will likely continue to seek Russian and Chinese assistance in upgrading its existing MiG-29s and Su-24s. This would be a more cost-effective way to enhance its current Iranian Air Force fighter jets inventory.
The acquisition of new fighter jets, particularly the Su-35, would be a significant development for the Iranian Air Force. However, the path to full operational integration is fraught with technical, logistical, and financial hurdles.

Maintenance and Readiness: Keeping the Fleet Airborne

One of the most remarkable aspects of the Iranian Air Force is its ability to keep an aging and diverse fleet operational under severe sanctions. This has necessitated a highly developed indigenous maintenance and repair capability, often involving reverse engineering and cannibalization of non-operational aircraft for parts. The "Data Kalimat" mentions the fear and grief among people after strikes on nuclear facilities, which, while not directly about maintenance, underscores the critical importance of a ready air force for national defense. Challenges include:
  • Spare Parts Shortages: This is the most persistent problem. For American-made aircraft, Iran relies on a clandestine market for parts, which are often expensive, of dubious quality, or counterfeit. For Russian/Chinese aircraft, political considerations can still impact the steady supply of spares.
  • Aging Airframes: Decades of service mean that the airframes themselves are reaching the end of their structural lives. Metal fatigue, corrosion, and wear and tear are constant concerns, requiring extensive inspections and repairs.
  • Technological Obsolescence: While Iran has made efforts to upgrade avionics and weapon systems, many of its aircraft lack modern radar, electronic warfare suites, and precision-guided munitions found in contemporary fighter jets.
  • Human Capital: Despite the challenges, Iranian technicians and engineers have demonstrated remarkable ingenuity. However, maintaining such complex systems without manufacturer support is a constant uphill battle, requiring continuous training and skill development.
The readiness levels of the Iranian Air Force fighter jets inventory are therefore a mixed bag. While some aircraft are kept in flying condition for deterrence and limited operations, the overall fleet readiness for sustained, high-intensity conflict is likely constrained.

Training and Doctrine: The Human Element of Air Power

Beyond the hardware, the effectiveness of any air force hinges on the quality of its pilots and ground crews, and the doctrine that guides their operations. Iranian pilots are known for their dedication and resourcefulness, often operating aircraft that many other nations would have long since retired. The "Data Kalimat" mentions the "Iranian peoples... identified chiefly by their native usage of any of the Iranian languages," highlighting a strong national identity that likely extends to its military personnel. Training challenges include:
  • Limited Flight Hours: Due to spare parts shortages and fuel costs, Iranian pilots likely receive fewer flight hours compared to their counterparts in more modern air forces. This can impact their proficiency in complex maneuvers and combat scenarios.
  • Lack of Advanced Simulators: Access to state-of-the-art flight simulators, crucial for training in advanced tactics and emergency procedures, is likely limited.
  • Outdated Tactics: While Iranian pilots are skilled, their training and doctrine may be based on older combat philosophies, given the age of their primary platforms. The integration of new platforms like the Su-35 would necessitate a complete overhaul of training and tactical doctrine.
Iran's air defense doctrine emphasizes a layered approach, integrating its fighter jets with a robust network of surface-to-air missile (SAM) systems. This strategy aims to compensate for the numerical and technological inferiority of its fighter fleet by creating a challenging environment for any aggressor. The recent regional tensions, where "life in Tel Aviv returns to normal while ceasefire between Israel and Iran holds," underscore the high stakes and the need for a well-trained, if not technologically superior, air force.

The Future Outlook: Challenges and Aspirations for 2025

As we approach 2025, the Iranian Air Force fighter jets inventory remains a complex and dynamic picture. The primary challenge will continue to be the modernization of its aging fleet in the face of persistent, albeit potentially easing, international pressure. While the lifting of the UN arms embargo offers a glimmer of hope for new acquisitions, the pace and scale of these procurements will depend on various factors:
  • Financial Constraints: Acquiring and integrating advanced fighter jets like the Su-35 is incredibly expensive, and Iran's economy, despite its oil wealth, has been severely impacted by sanctions.
  • Geopolitical Realities: While the UN embargo is lifted, unilateral sanctions by the US and its allies could still complicate arms deals. Countries like Russia and China might weigh their relationships with other global powers before making large-scale transfers.
  • Operational Integration: Even if new aircraft are acquired, integrating them into the existing fleet, training personnel, and establishing a robust maintenance infrastructure will take years.
By 2025, the Iranian Air Force will likely still be dominated by its aging American and Soviet-era aircraft, kept flying through ingenious maintenance and indigenous efforts. Any new acquisitions, such as the Su-35, will likely be in small numbers, serving primarily as a strategic deterrent and a symbol of modernization rather than a complete overhaul of the fleet. Iran's long-term aspiration is to achieve greater self-sufficiency in defense, building on its historical resilience as a nation that has endured for millennia, with "over 98 percent of Iranians supported an Islamic Republic" after the revolution, reflecting a strong sense of national will. In conclusion, the Iranian Air Force fighter jets inventory in 2025 will continue to reflect Iran's unique geopolitical circumstances: a blend of historical legacy, indigenous innovation, and strategic adaptation in the face of formidable challenges. While not possessing the most technologically advanced air force, Iran's ability to maintain and potentially augment its air power demonstrates a remarkable determination to secure its skies and assert its regional role.
