The Genesis of the IRIAF: From Imperial Might to Revolutionary Air Power

The history of the Islamic Republic of Iran Air Force (IRIAF) is intrinsically linked to the tumultuous events of the late 1970s. Prior to the 1979 Islamic Revolution, Iran boasted one of the most advanced air forces in the region, known as the Imperial Iranian Air Force (IIAF). This force was heavily equipped with state-of-the-art Western aircraft, primarily from the United States. Iconic models like the F-14 Tomcat, F-4 Phantom II, and F-5 Freedom Fighter formed the backbone of its aerial power, representing a significant investment and a close military alliance with the West. The IIAF was a symbol of the Shah's modernization efforts and his ambition to establish Iran as a dominant regional power.

A Legacy of Western Equipment

When the Islamic Revolution swept through Iran in February 1979, the Imperial Iranian Air Force was renamed, giving birth to the Islamic Republic of Iran Air Force. This transformation was not merely a change of name; it marked a fundamental shift in doctrine, alliances, and operational capabilities. Overnight, the IRIAF found itself cut off from its primary suppliers of aircraft, spare parts, and technical support. The vast inventory of American-made jets, while still potent on paper, became a logistical nightmare. Maintaining these complex machines without manufacturer support required immense ingenuity, reverse-engineering efforts, and, at times, clandestine procurement channels. The legacy of these Western allies' jets continues to define a significant portion of Iran's air force to this day, a testament to the durability of the aircraft and the persistence of Iranian engineers. This reliance on a great number of jets made by former Western allies is a defining characteristic of the IRIAF's operational profile.

Iran's Global Military Standing: A Top 20 Power?

When assessing the "Iran Air Force size" and its overall military might, it's important to place it within a broader global context. According to the Global Firepower (GFP) index, which evaluates the military strength of nations based on over 60 factors, Iran is indeed considered a top 20 global military power. For 2025, Iran is ranked 16 out of 145 countries considered for the annual GFP review. This ranking might surprise some, given the common perception of Iran's military as being technologically backward due to sanctions. However, the GFP index takes into account a wide array of factors beyond just cutting-edge technology, including manpower, geographical advantage, natural resources, financial stability, and logistical capabilities.

The GFP Index and PWRINDX Score

The nation holds a PWRINX* score of 0.3048, where a score of 0.0000 is considered "perfect." This score reflects a comprehensive evaluation of its military assets and potential. While the score indicates a significant military presence, it also highlights areas where Iran falls short of a perfect, idealized military machine. On paper, Iran holds a numerical edge with a population of 88 million and vast territory, dwarfing Israel's 9 million people and compact size. This demographic and geographic advantage contributes significantly to its GFP ranking, providing a large pool of potential manpower and strategic depth. However, these figures alone do not tell the whole story, especially when it comes to the qualitative aspects of its air force.

Unpacking the Numbers: Iran Air Force Size in Detail

Understanding the true "Iran Air Force size" requires dissecting the raw numbers and placing them in context. The service currently counts 400 total units in its active aircraft inventory. This figure represents the operational fleet that is regularly flown and maintained. However, other analyses suggest a higher overall number. Some analysts believe the figure is far higher, with Iran possessing a total of 551 aircraft across its various branches. This discrepancy often arises from different definitions of "active" versus "total" inventory, including aircraft in storage, undergoing deep maintenance, or assigned to non-combat roles.

Active Inventory vs. Total Aircraft

Crucially, out of the total 551 aircraft, only 186 are classified as fighters. This distinction is vital because while a large number of transport, reconnaissance, or training aircraft contribute to overall air power, it is the fighter fleet that determines a nation's ability to project air superiority, conduct offensive operations, and defend its airspace. The 186 fighter aircraft represent the core of Iran's aerial combat capability. Furthermore, the Iranian air force has 37,000 personnel dedicated to its operations. This significant manpower suggests a robust infrastructure for training, maintenance, and support, even if the number of deployable combat aircraft is relatively low. The sheer size of its personnel indicates a commitment to maintaining a formidable air arm, despite the challenges it faces.

The Ageing Fleet: A Challenge for Modern Warfare

One of the most significant challenges facing the "Iran Air Force size" and its operational effectiveness is the advanced age of its aircraft fleet. Most of Iran's fighters are old and outdated. These include models acquired before the Iranian Revolution of 1979, such as the aforementioned F-4 Phantoms, F-5 Freedom Fighters, and even the sophisticated F-14 Tomcats. While these aircraft were cutting-edge in their prime, decades of service, coupled with the inability to procure modern replacements or original spare parts, have taken a toll. The ones that aren’t old are just new copies of old designs. This refers to Iran's domestic production efforts, which often involve reverse-engineering or building new airframes based on existing, older blueprints, rather than developing truly next-generation platforms.

Reliance on Older Designs

The reliance on older aircraft makes the IRIAF less effective in direct confrontations with technologically superior adversaries. While Iranian engineers have shown remarkable ingenuity in keeping these legacy aircraft flying through reverse-engineering and domestic parts production, their fundamental design limitations remain. They lack the stealth capabilities, advanced avionics, sophisticated radar systems, and precision-guided munitions that characterize modern fourth and fifth-generation fighters. For instance, between 1951 and 1986, some 2,900 of the F-5 type were produced for various global customers. While Iran has kept many of these flying, they are fundamentally less capable than contemporary designs. This technological gap significantly impacts the IRIAF's ability to operate in contested airspace or engage in high-intensity aerial combat scenarios, making the qualitative aspect of its "Iran Air Force size" a critical point of concern.

Manpower and Operational Readiness

Beyond the sheer number of aircraft, the human element is a critical factor in assessing the "Iran Air Force size" and its combat readiness. The Iranian air force has 37,000 personnel. This substantial workforce is responsible for everything from pilot training and aircraft maintenance to logistics and ground support. However, despite this large personnel count, the effectiveness of the air force is hampered by a critical shortage of working strike aircraft. The data suggests that Iran has only a few dozen working strike aircraft, including Russian jets and aging U.S. models acquired before the Iranian revolution of 1979. This disparity between manpower and operational assets raises questions about the overall readiness and deployability of the IRIAF. A large number of personnel might be engaged in maintaining a relatively small number of operational aircraft, or in training for platforms that are scarce. It also implies that a significant portion of the force might be dedicated to air defense roles, which are less reliant on a large fleet of offensive strike aircraft, but rather on missile systems and radar networks. The focus on air defense capability has indeed been stepped up, as efforts to increase Iran’s air defense capability also have been stepped up. This strategic shift reflects an understanding of the limitations of its offensive air power and a prioritization of defensive measures against potential aerial threats.

Dual Structure and Doctrine: Shaping Iran's Air Power

The Islamic Republic of Iran's air power is defined by a unique dual structure and a doctrine shaped by decades of international sanctions and regional rivalries. Unlike many nations with a single, unified air force, Iran operates with two distinct aerial arms: the Islamic Republic of Iran Air Force (IRIAF) and the Islamic Revolutionary Guard Corps Aerospace Force (IRGC-AF). While the IRIAF, as discussed, is the traditional air force stemming from the Imperial era, the IRGC-AF operates independently, focusing more on strategic missile capabilities, drone operations, and potentially some close air support or transport roles. This dual structure can lead to both redundancy and specialization, but it also reflects the complex internal power dynamics within Iran's military establishment. Decades of international sanctions have profoundly influenced Iran's military doctrine, particularly concerning its air power. Unable to procure modern combat aircraft from major international suppliers, Iran has been forced to adopt a strategy of self-reliance and asymmetric warfare. This means focusing on areas where it can leverage its strengths and exploit the weaknesses of potential adversaries, rather than engaging in a conventional arms race it cannot win. For its air force, this translates into maximizing the operational lifespan of its existing fleet, investing in domestic maintenance and upgrades, and developing indigenous capabilities in areas like drones and ballistic missiles, which can compensate for deficiencies in conventional air power. Its navy, while relatively large, consists primarily of smaller vessels designed for coastal defense and asymmetrical warfare, such as missile boats and submarines, mirroring the air force's strategic adaptation.

Comparing Aerial Might: Iran vs. Regional Powers

To truly grasp the significance of the "Iran Air Force size," it's imperative to compare it with its regional adversaries, particularly Israel, which is often considered the benchmark for military technological prowess in the Middle East. The contrast between the two air forces highlights the qualitative gap that exists. Israel deploys 240 fighter jets, a numerically superior force compared to Iran's 188 fighter aircraft. However, the qualitative difference is even more stark. Israel’s aircraft are equipped with superior avionics, radar systems, and weapons, giving it air superiority in any likely engagement. The Israeli Air Force (IAF) operates modern, fourth and fifth-generation fighters like the F-15 Eagle, F-16 Fighting Falcon, and the cutting-edge F-35 Lightning II. These aircraft possess advanced capabilities for beyond-visual-range combat, electronic warfare, and precision strike, making them vastly more effective in a modern aerial battlefield. In contrast, Iran’s air force continues to rely heavily on older aircraft, making it less effective in direct confrontations. While Iran's F-14 Tomcats, for example, were once formidable, they lack the sophisticated network-centric warfare capabilities and stealth technology of Israel's newer jets. This technological disparity means that even if Iran could put all its 188 fighters into the air, they would face a significant disadvantage against a smaller, but qualitatively superior, Israeli force. With an estimated 350 antiquated planes in its air force, it lags far behind Israel in both quantity and quality of its combat aircraft. The naval comparison also sheds light on the strategic priorities. Israel’s navy fields 62 ships—7 corvettes, 5 submarines, 46 patrol vessels, with no frigates or mine warfare craft. This composition reflects a focus on coastal defense, special operations, and maintaining sea lines of communication in a relatively compact maritime environment. While the "Data Kalimat" doesn't provide specific numbers for Iran's navy, it notes that its navy, while relatively large, consists primarily of smaller vessels designed for coastal defense and asymmetrical warfare, such as missile boats and submarines. This further underscores Iran's overall military doctrine of asymmetric defense, where quantity and unconventional tactics are emphasized over conventional, high-tech power projection, especially in its air and naval forces.

The Future of Iran's Air Force: Modernization Amidst Sanctions

The future of the "Iran Air Force size" and its capabilities is a subject of intense speculation and strategic importance. Decades of sanctions have severely hampered Iran's ability to modernize its air fleet through conventional means. This has forced the IRIAF to pursue a two-pronged strategy: maximizing the operational life of its existing legacy aircraft and investing heavily in indigenous defense industries. Efforts to increase Iran’s air defense capability also have been stepped up. Recognizing the vulnerability of its aging fighter fleet to modern aerial threats, Iran has focused on acquiring and developing advanced surface-to-air missile (SAM) systems. These include Russian-supplied S-300 systems and domestically produced equivalents, forming a layered air defense network designed to deter and intercept incoming aircraft and missiles. This emphasis on ground-based air defense is a pragmatic response to the limitations of its fighter arm. While Iran has made some recent Russian additions to its air force, these acquisitions have been limited and have not fundamentally altered the overall picture of an aging fleet. The prospect of Iran acquiring more advanced Russian or Chinese fighter jets remains a significant concern for regional powers and the West. However, such large-scale acquisitions are often constrained by financial limitations and the lingering threat of secondary sanctions. The IRIAF's future will likely continue to be defined by its ingenuity in maintaining its current fleet, its slow but steady progress in domestic aircraft development (often based on older designs), and its reliance on asymmetric capabilities like drones and missiles to compensate for its conventional air power shortcomings. The strategic importance of its geographical location and large population will continue to make it a significant military actor, even if its "Iran Air Force size" in terms of cutting-edge combat aircraft remains relatively modest compared to its rivals.

Conclusion

The "Iran Air Force size" is a multifaceted issue, reflecting a military force shaped by revolution, resilience, and restraint. While global military indices rank Iran as a top 20 power, a closer look at its air force reveals a story of numerical strength tempered by technological limitations. With an active inventory of 400 units, including 186 fighter aircraft, and a dedicated personnel force of 37,000, the IRIAF possesses a significant presence. However, its heavy reliance on aging, pre-1979 Western models and domestically produced copies of old designs presents a substantial challenge in the face of modern aerial warfare. Compared to technologically advanced regional adversaries like Israel, Iran's air force faces a qualitative disadvantage, particularly in avionics, radar, and weapons systems. This has driven Iran to adopt a dual-structure approach, focusing on asymmetric capabilities, and bolstering its air defense networks. The future of the IRIAF will undoubtedly involve continued efforts to sustain its existing fleet and develop indigenous solutions, all while navigating the complexities of international sanctions and regional rivalries. Understanding these nuances is crucial for any comprehensive assessment of Iran's true aerial power. What are your thoughts on the future trajectory of Iran's air force?
