The IRIAF: Origins and Evolution
The Islamic Republic of Iran Air Force (IRIAF; Persian: نیروی هوایی ارتش جمهوری اسلامی ایران, romanized: Niruye Havâyiye Arteše Jomhuriye Eslâmiye Irân) serves as the aviation branch of the Islamic Republic of Iran Army. Its present form emerged directly from the Imperial Iranian Air Force (IIAF), which was renamed in 1979 following the Islamic Revolution. This renaming marked a pivotal moment, not just politically, but also militarily. The IIAF, under the Shah, had been one of the most advanced air forces in the region, equipped with sophisticated American aircraft like the F-14 Tomcat, F-4 Phantom II, and F-5 Freedom Fighter. These aircraft were procured in large numbers, establishing a formidable aerial capability that was the envy of many neighboring states. However, the revolution, followed by the Iran-Iraq War and decades of international sanctions, drastically altered the IRIAF's trajectory. The once-robust supply chain for spare parts and new technologies from Western allies was severed. This forced Iran to become self-reliant, developing a unique approach to maintaining and operating its existing fleet, often through reverse engineering, cannibalization, and clandestine procurement. This historical context is vital for understanding why Iran's air force today looks the way it does, heavily reliant on a legacy of Western-made jets that have long since been retired from frontline service in their countries of origin.An Overview of the Current Fighter Fleet
Today, the air force of the Islamic Republic of Iran (IRIAF) relies on obsolete aircraft in its fighter aviation. The roster is dense with aging 3rd and 2nd generation fighters, a stark contrast to the 4th and 5th generation aircraft that dominate the skies of many other powerful nations. This reliance on older platforms presents significant challenges in terms of operational readiness, technological parity, and overall combat effectiveness. The following represents an overview of the modern aerial fighting capabilities of the Islamic Republic of Iran Air Force (2025), as we take a closer look at its composition.The Enduring Legacy of Western Allies
Iran's air force relies on a great number of jets made by former Western allies. Aircraft like the venerable F-14 Tomcats, F-4 Phantoms, and F-5 Freedom Fighters, originally supplied by the United States before the revolution, form the backbone of Iran's fighter fleet. Despite their age, these aircraft have been meticulously maintained and, in some cases, reportedly upgraded by Iranian technicians and engineers. The F-14 Tomcats, in particular, are a unique asset, as Iran is the only country outside the United States to have operated them, and now, the only one to still have them in active service. This necessitates an extraordinary level of ingenuity and technical skill to keep these complex machines flying without official manufacturer support. Beyond the American-made jets, the IRIAF also operates a limited number of Soviet-era aircraft, primarily MiG-29s and Su-24s, acquired from various sources over the years. These additions, while providing some diversification, do not fundamentally alter the overall picture of an air force struggling with an aging inventory. The challenge lies not just in keeping these jets operational, but in ensuring they can perform effectively against modern threats, which increasingly involve stealth technology, advanced electronic warfare, and sophisticated air-to-air missiles.Current Fleet Numbers and Composition
The service currently counts 400 total units in its active aircraft inventory. This figure encompasses a wide range of aircraft types, including transport planes, helicopters, and trainers, in addition to the fighter jets. When focusing specifically on fighter aircraft, the numbers become more nuanced. While there are a total of 48 active Iranian air force aircraft (2025) entries in the military factory databases, which might refer to specific operational models or a subset of the total fleet, the overall fighter inventory is a mix of varying readiness levels. For instance, in some contexts, it has been noted that "in all, 80 units were" referring to a specific type or category of fighter aircraft. This mix of numbers highlights the difficulty in precisely quantifying Iran's operational fighter strength. Many of these aircraft are likely in various states of repair or readiness, with only a fraction being combat-ready at any given time. The sheer diversity of platforms, coupled with the age of the majority of the fleet, presents significant logistical and maintenance hurdles, impacting the IRIAF's ability to deploy large numbers of modern combat aircraft efficiently.Indigenous Development: The HESA Kowsar
Faced with persistent international sanctions and an aging foreign-supplied fleet, Iran has invested significantly in indigenous defense production, particularly in its aviation sector. A notable outcome of these efforts is the HESA Kowsar. This aircraft is claimed to be heavily upgraded and indigenously made, representing Iran's ambition to achieve self-sufficiency in military aviation. The Kowsar, unveiled in 2018, is visually similar to the American F-5, leading many to believe it is a reverse-engineered or heavily modified version of the venerable fighter. However, Western analysts have described the plane as inefficient as a weapon, but having potential for training a new generation of Iranian fighter pilots. This assessment suggests that while the Kowsar may not be a cutting-edge combat aircraft capable of challenging modern adversaries, it serves a crucial role in Iran's long-term strategy. By manufacturing its own fighter jets, even if based on older designs, Iran can ensure a continuous supply of airframes for pilot training, maintain its aviation industrial base, and reduce its reliance on external sources. This capability, regardless of its combat effectiveness, highlights the evolution and strategic priorities of the Iranian armed forces, emphasizing self-reliance and the development of local expertise.Strategic Challenges: The "Weakest Military Link"
Iran’s air force has long been, and remains, Tehran’s weakest military link. This assessment is widely shared among military strategists and regional observers. The primary reason for this vulnerability lies in the advanced age and technological obsolescence of its fighter jet fleet. While Iranian engineers and technicians have shown remarkable ingenuity in keeping these aircraft operational for decades beyond their expected service life, these efforts cannot entirely bridge the technological gap with modern air forces. The aging 3rd and 2nd generation fighters in the IRIAF roster lack the stealth capabilities, advanced avionics, beyond-visual-range missile systems, and sophisticated electronic warfare suites that are standard in contemporary aerial combat. This places them at a significant disadvantage against more modern adversaries. Furthermore, the limited availability of spare parts, coupled with the challenges of maintaining such a diverse and old fleet, impacts overall readiness rates and the ability to project air power effectively. This inherent weakness compels Iran to rely more heavily on other asymmetric capabilities, such as ballistic missiles, drones, and naval assets, to deter potential aggressors and project influence in the region.Regional Dynamics and External Pressures
The operational context of Iran's air force is heavily influenced by the complex regional dynamics and the constant external pressures it faces. The Middle East is a hotbed of military activity, with various regional powers and international actors possessing highly capable air forces. This environment necessitates a constant state of vigilance for the IRIAF, despite its limitations.Alleged Air Defense Vulnerabilities
Reports and claims from various sources often highlight the vulnerabilities of Iranian air defenses, which directly impact the operational environment for Iran's fighter jets. For instance, there have been claims that Israel’s customized jets pound Iranian military targets, with nearly 200 warplanes hitting 100 targets in specific incidents. Crucially, it has been alleged that many of these attacks were specifically designed to neutralize Iranian air defenses first. Once the air defenses were struck, the IAF fighter jets were reportedly able to fly freely over Iranian airspace, achieving their objectives with reduced risk. These alleged incidents, some of which were revealed by figures like Effie Defrin in a press conference, underscore a critical challenge for the IRIAF: the synergy between its air defense network and its fighter fleet. If the air defense system can be compromised, it leaves the slower, older fighter jets even more exposed to advanced enemy aircraft. This vulnerability necessitates a continuous effort by Iran to upgrade its air defense systems, including radar, surface-to-air missiles, and command-and-control networks, to provide a safer operational environment for its fighter pilots.Noteworthy External Military Deployments
The presence and activities of external military forces, particularly those of the United States, also shape the IRIAF's strategic calculations. Following the sudden and massive deployment of U.S. Air Force aerial refueling aircraft on June 16, 2025, reports quickly spread about the ongoing deployment of U.S. military assets in the region. Such deployments, whether for exercises, deterrence, or in response to specific events, create a dynamic and challenging airspace for Iran. These large-scale deployments, involving advanced aircraft and support systems, serve as a constant reminder of the technological disparity between the IRIAF and potential adversaries. They compel Iran to continually assess its readiness, develop asymmetric responses, and refine its defensive strategies, even as it grapples with the limitations of its aging fighter jet fleet. The need to monitor and potentially respond to such significant military movements places an immense burden on the IRIAF's resources and personnel.Training a New Generation and Future Prospects
Despite the challenges, the IRIAF continues to focus on training a new generation of fighter pilots. The HESA Kowsar, as discussed, plays a vital role in this, providing a locally produced platform for basic and advanced flight training. This ensures a steady supply of trained personnel, even if the aircraft they train on are not state-of-the-art. The emphasis on indigenous training platforms is a pragmatic response to sanctions, ensuring that the IRIAF can sustain its human capital development regardless of external pressures. Looking ahead, the future prospects for Iran's air force are complex. While there are persistent rumors and reports of potential acquisitions of advanced fighter jets from allies like Russia or China, such deals have historically been complicated by sanctions and geopolitical considerations. Should Iran manage to acquire modern 4th or 4.5 generation aircraft, it would significantly alter the regional balance of power. However, integrating such complex systems, training pilots and ground crews, and establishing maintenance infrastructure would be a monumental task, requiring substantial investment and time. Until then, the IRIAF will likely continue its strategy of maximizing the operational life of its existing fleet through upgrades and indigenous support, while focusing on pilot training and integrated air defense strategies to compensate for its aerial limitations.The Collective Contribution of Iran's Combat Aircraft Fleet
While individually, many of Iran's fighter jets might be considered obsolete, these fighter jets collectively contribute to the effectiveness of Iran’s combat aircraft fleet, allowing for a versatile and resilient air force that can respond to various operational scenarios. This collective strength is derived from several factors. Firstly, the sheer number of operational aircraft, even if older, provides a deterrent capability and the capacity for sustained operations, albeit at a lower technological level. Secondly, Iran has invested heavily in integrating its air defense systems with its air force, aiming to create a layered defense that can compensate for the individual limitations of its aircraft. The IRIAF's strategy often involves using its older fighters in roles where their limitations are less pronounced, such as ground attack, close air support, or as interceptors against less advanced threats. They are also crucial for maintaining air superiority over Iranian airspace during lower-intensity conflicts or for training purposes. The integration of these aircraft highlights the evolution and strategic priorities of the Iranian armed forces, emphasizing a multi-layered approach to national defense that leverages all available assets. This adaptive strategy, born out of necessity, allows the IRIAF to remain a relevant, albeit constrained, player in regional air power dynamics.Conclusion: Navigating a Complex Aerial Future
