Iran's Overall Military Standing in 2025

To truly understand "how strong is Iran's Air Force," it's essential to first contextualize it within the broader framework of Iran's overall military capabilities. Iran’s military strength has evolved significantly over the past decades, adapting to a unique set of geopolitical pressures and strategic objectives. Unlike many nations that prioritize cutting-edge technology and global power projection, Iran's defense strategy has largely focused on deterrence, asymmetric warfare, and regional influence.

According to the 2025 Global Firepower Report, a widely respected assessment of global military strengths, Iran ranks 16th out of 145 countries. This places Iran firmly within the top 20 global military powers. The report assigns Iran a Power Index score of 0.3048, where a score of 0.0000 is considered 'perfect.' This global standing illustrates not only the scale of Iran’s defense capabilities but also its strategic importance in the Middle East. The data, last reviewed on January 9, 2025, confirms Iran's consistent presence among the world's more formidable military forces, despite facing decades of international sanctions and isolation. While this ranking encompasses all branches of its armed forces – land, sea, and air – it provides a crucial backdrop against which to assess the specific strengths and weaknesses of its air power.

The Islamic Republic of Iran Air Force (IRIAF): A Historical Perspective

Iran’s air force, officially known as the Islamic Republic of Iran Air Force (IRIAF), is a critical component of the Iranian armed forces. Its history is deeply intertwined with the political transformations of the nation, marking distinct periods of growth, decline, and adaptation. Established in the 1920s, the IRIAF has evolved significantly, particularly after the pivotal 1979 Islamic Revolution, adapting to profound geopolitical shifts and regional security dynamics.

From Imperial Might to Revolutionary Challenges

Prior to the 1979 Islamic Revolution, when it was known as the Imperial Iranian Air Force (IIAF), Iran's air force was arguably the most powerful force of its kind in the Middle East. In the 1970s, it rivaled the Israeli Air Force in terms of sophistication and capability. The Shah's government, flush with oil revenues and strong ties with the West, expensively equipped the IIAF with all the most modern aircraft models of the time, including advanced U.S. jets like the F-14 Tomcat, F-4 Phantom, and F-5 Tiger. This era represented the zenith of Iranian air power, demonstrating a significant capacity for conventional aerial warfare.

However, this era of unparalleled strength was abruptly curtailed by the 1979 revolution. The present air force was created when the Imperial Iranian Air Force was renamed in 1979 following the Iranian Revolution. The severing of ties with the West, particularly the United States, meant an immediate halt to spare parts, maintenance support, and new aircraft acquisitions. This sudden isolation, compounded by the devastating Iran-Iraq War (1980-1988), severely impacted the IRIAF's operational readiness and long-term viability. Many of its advanced aircraft became "hangar queens" due to a lack of spare parts, and the war effort further degraded its remaining assets. This historical context is vital in understanding the current state of "how strong is Iran's Air Force" today.

Structure and Personnel: Understanding Iran's Air Power

When assessing "how strong is Iran's Air Force," it's important to recognize that Iran's military structure is somewhat unique, featuring two parallel military organizations: the conventional armed forces (Artesh) and the Islamic Revolutionary Guard Corps (IRGC). Both entities maintain their own air assets, which can lead to complexities in a holistic assessment of Iranian air power.

The Artesh, which includes the Islamic Republic of Iran Air Force (IRIAF), focuses on conventional military operations, encompassing land, naval, and air forces. The IRIAF is responsible for defending Iran's airspace, conducting air superiority missions, and providing close air support to ground forces. It is reported that the Iranian air force has 37,000 personnel, a substantial number that speaks to its organizational depth, even if its operational fleet is limited.

The Dual Air Forces: IRIAF and IRGC-AF

Conversely, the IRGC was set up 40 years ago to defend the Islamic system in Iran and has become a major military, political, and economic force. The IRGC has its own navy and air force, and oversees Iran's strategic weapons, including its ballistic missile program. While the IRGC Air Force (IRGC-AF) primarily focuses on missile defense, drone operations, and unconventional air support, the IRIAF remains the primary conventional air combat arm. Both forces operate dozens of fighter jets, though the IRIAF typically fields the more traditional combat aircraft, while the IRGC-AF might utilize a mix of repurposed fighters, transport aircraft, and a growing drone fleet. This dual structure means that the total air power available to Iran is a combination of these two entities, each with distinct roles and capabilities.

The Aging Fleet: A Closer Look at IRIAF's Aircraft

Perhaps the most significant factor influencing "how strong is Iran's Air Force" today is the age and composition of its operational fleet. Despite its large personnel count, the IRIAF has only a few dozen working strike aircraft. This critical limitation stems from decades of international sanctions that have severely restricted Iran's ability to acquire modern combat aircraft and the necessary spare parts for its existing fleet.

Legacy Assets and New Additions

Much of Iran's air force dates from the Shah era, comprising aging U.S. models acquired before the Iranian Revolution of 1979. These include iconic aircraft like the F-14 Tomcat, F-4 Phantom II, and F-5 Tiger II. While these were cutting-edge aircraft in their prime, maintaining them for over four decades without manufacturer support is a monumental challenge. Iran has resorted to reverse-engineering parts, developing indigenous maintenance capabilities, and sometimes acquiring components through clandestine means.

Adding to this eclectic mix are aircraft left over from dictator Saddam Hussein’s Iraqi Air Force, which moved many of its planes to Iran during the 1991 Persian Gulf War to avoid destruction by coalition forces. These include various models of French-made Mirage F1s and Soviet-era MiG-29s and Su-24s. More recently, Iran has made efforts to modernize its fleet, primarily through Russian additions. These newer acquisitions, such as the Sukhoi Su-35, represent a significant upgrade in capability, but their numbers are still limited. While official figures often state "a few dozen working strike aircraft," some analysts believe the figure is far higher, suggesting that Iran's ingenuity in maintenance and indigenous production might keep more aircraft operational than publicly acknowledged. However, even if the number is higher, the overall technological gap with modern air forces remains substantial.

Challenges and Degradation: The Impact of Geopolitics

The question of "how strong is Iran's Air Force" cannot be answered without acknowledging the immense challenges it faces. Beyond the aging fleet and the difficulty of acquiring modern platforms, Iran's air force, along with its proxies and conventional forces, is believed to have been heavily degraded by Israeli and U.S. military operations over the past year. These operations, often targeting Iranian assets or those of its proxies in the region, exert constant pressure and force Iran to expend resources on defense and recovery.

Sanctions, both international and unilateral, have been a persistent hurdle. They not only prevent Iran from purchasing new, advanced aircraft from major manufacturers but also make it incredibly difficult to obtain spare parts, avionics, and other critical components needed to maintain its existing fleet. This forces Iran to rely on reverse engineering, domestic production, and illicit procurement networks, which are often inefficient and produce lower-quality results. The lack of access to modern training, simulation, and doctrine from leading air powers also limits the IRIAF's ability to evolve its operational tactics and strategies. This continuous degradation and the struggle for modernization significantly impact the overall assessment of "how strong is Iran's Air Force" in a conventional conflict scenario.

Strategic Imperatives: Why Air Power Matters to Iran

Despite the challenges, Iran's air force remains a vital component of its defense strategy, reflecting its strategic importance in a volatile region. In 2025, tensions in the Middle East remain high, making air power a critical element for both deterrence and potential conflict. For Iran, its air force serves several key strategic imperatives:

Air Defense: Protecting Iran's vast airspace from potential incursions is a primary role. While older aircraft may struggle in offensive roles, they can still contribute to a layered air defense system, especially when integrated with ground-based missile systems.
Deterrence: The mere existence of a combat-capable air force, even if limited, acts as a deterrent against potential adversaries. It complicates any offensive planning by raising the stakes and potential costs.
Conventional Military Operations: The Artesh's air force, equipped with fighter jets and helicopters, is designed to support conventional ground forces with air superiority, close air support, and reconnaissance missions.
Symbolic Power: Maintaining an air force, even with older models, is a symbol of national sovereignty and military capability on the global stage.
Support for Strategic Weapons: While the IRGC oversees strategic weapons, the IRIAF could potentially play a role in protecting launch sites or providing reconnaissance for missile operations.

Given these imperatives, Iran continues to invest in maintaining and incrementally upgrading its air force, understanding that even a limited air capability is better than none in a region where air superiority often dictates the outcome of conflicts. The ongoing struggle to keep these aircraft flying underscores the strategic value Iran places on its air power, regardless of the significant hurdles.

Comparing Iran's Air Force to Global Powers

To fully grasp "how strong is Iran's Air Force," it's helpful to compare it to leading global air powers. While Iran ranks 16th overall in military strength, its air force specifically faces significant qualitative and quantitative disparities when stacked against the world's top air forces. This comparison highlights the scale of the challenge Iran faces in modernizing its aerial capabilities.

A Look at the USAF Benchmark

Consider the United States Air Force (USAF), which holds the highest attainable TVR (True Value Rating) score of 242.9. The USAF features a broad mix of aircraft types, from stealth fighters like the F-22 and F-35, to advanced bombers like the B-2 and B-52, and a vast array of surveillance, reconnaissance, transport, and support aircraft. Its strength is not only in the technological superiority of individual platforms but also in the sheer numbers (quantity) and the balance strengthened by overall numbers across all categories. The USAF's capabilities extend to global reach, precision strike, advanced electronic warfare, and robust logistical support, none of which Iran can currently match.

This stark contrast underscores that while Iran possesses a respectable overall military ranking, its air force operates on a fundamentally different level compared to a top-tier air power. Iran's air force is designed for regional defense and deterrence, relying on ingenuity and limited acquisitions, whereas leading air forces are built for global power projection and dominance across all domains of air warfare. Therefore, when asking "how strong is Iran's Air Force," the answer largely depends on the context: strong enough for regional defense and asymmetric operations, but significantly outmatched by major global powers.

The Future Outlook for Iran's Air Force

The future of "how strong is Iran's Air Force" remains a subject of considerable speculation and is heavily dependent on geopolitical developments, particularly the future of sanctions and Iran's relationships with key military suppliers like Russia and China. As of 2025, Iran continues to face an uphill battle in modernizing its air fleet.

One of the most anticipated developments is the potential acquisition of more advanced Russian aircraft, such as the Su-35 Flanker-E. Such acquisitions would represent a significant qualitative leap for the IRIAF, providing it with more modern capabilities in terms of radar, weaponry, and electronic warfare compared to its aging Western and Soviet-era jets. However, the scale of these acquisitions is likely to be limited by financial constraints and ongoing international pressure.

Beyond foreign acquisitions, Iran will likely continue to invest in its indigenous aerospace industry. This includes efforts to reverse-engineer foreign designs, develop its own drone technology (where it has shown considerable progress), and potentially produce domestic fighter jets, though these are often based on older designs and face significant technological hurdles. The focus will likely remain on maintaining operational readiness of existing aircraft through innovative maintenance and parts manufacturing, alongside integrating new technologies where possible, especially in areas like electronic warfare and missile systems.

Ultimately, while Iran's overall military strength positions it as a significant regional player, its air force will likely remain constrained by its legacy fleet and the persistent challenges of sanctions. Its strength will continue to be measured more by its resilience and adaptive strategies in the face of adversity, rather than by cutting-edge technology or overwhelming numbers.

Conclusion

In conclusion, assessing "how strong is Iran's Air Force" reveals a multifaceted reality. On one hand, Iran's military, as a whole, is undeniably robust, ranking 16th globally in 2025 according to the Global Firepower Report. This reflects a significant capacity for defense and regional influence. However, when focusing specifically on its air force, a different picture emerges.

The Islamic Republic of Iran Air Force (IRIAF) is a force steeped in history, transitioning from a formidable regional power in the 1970s to a resilient but largely aging entity today. With 37,000 personnel, it maintains a substantial human capital, yet its operational fleet consists of only a few dozen working strike aircraft, largely comprising pre-1979 U.S. models and remnants from the Iran-Iraq War, supplemented by limited recent Russian additions. Decades of sanctions and recent military operations have heavily degraded its conventional air capabilities, forcing Iran to rely on ingenuity, indigenous production, and a dual-force structure with the IRGC.

While the IRIAF is far from matching the technological prowess and numerical superiority of global air powers like the United States, it remains a critical component of Iran's deterrence strategy and conventional defense. Its strength lies in its ability to adapt, maintain, and operate an eclectic mix of aircraft under severe constraints, rather than in its offensive power projection. As tensions persist in the Middle East, understanding this nuanced reality of Iran's air power is crucial for assessing regional stability.
