The Genesis of the IRIAF: A Historical Overview

To truly grasp the current state of Iran Air Force capabilities, one must first look back at its origins. The foundation of modern Iranian air power was laid during the Pahlavi dynasty, with significant investments in Western-made aircraft and training. The Imperial Iranian Air Force (IIAF) was, at one point, one of the most advanced air forces in the region, equipped with cutting-edge American aircraft like the F-14 Tomcat and F-4 Phantom II. This era of close military ties with the West provided Iran with a substantial and technologically advanced aerial fighting capability.

However, the Iranian Revolution of 1979 marked a pivotal turning point. The Imperial Iranian Air Force was renamed the Islamic Republic of Iran Air Force (IRIAF), and its operational landscape dramatically shifted. Sanctions imposed by Western nations, particularly the United States, severed the supply chain for spare parts, maintenance, and new aircraft. This forced the newly formed IRIAF to become incredibly resourceful, relying heavily on its existing inventory and developing innovative solutions for maintenance and repair. The Iran-Iraq War (1980-1988) further tested the IRIAF's resilience, pushing its aging fleet and limited resources to their absolute limits, yet demonstrating its capacity for sustained operations under duress.

Unpacking the Structure of Iran's Aerial Power

The Iranian armed forces are a complex entity, comprising the Islamic Republic of Iran Army (Artesh), the Police Command (Faraja), and the Islamic Revolutionary Guard Corps (Sepah), often abbreviated as IRGC. Within this structure, the IRIAF serves as the primary conventional air force, falling under the Artesh. However, it's crucial to understand that the IRGC also maintains its own air arm, known as the IRGC Aerospace Force, which operates a range of aircraft, drones, and ballistic missiles, often focusing on asymmetric warfare and strategic deterrence.

The IRIAF and IRGC Air Force

While the IRIAF handles traditional air superiority, ground attack, and transport roles, the IRGC Aerospace Force has grown significantly in recent decades, particularly in the development and deployment of unmanned aerial vehicles (UAVs) and advanced missile systems. This dual structure allows Iran to pursue different strategic objectives: the IRIAF maintains a more conventional posture for national defense, while the IRGC Aerospace Force focuses on projecting power and deterring adversaries through unconventional means. Understanding the distinct, yet often complementary, roles of these two aerial branches is key to assessing the full scope of Iran Air Force capabilities.

Iran's Air Force Capabilities: A Diverse Fleet

The service currently counts approximately 400 total units in its active aircraft inventory, according to an overview of modern aerial fighting capabilities of the Islamic Republic of Iran Air Force (2025 data). This number, while seemingly robust, masks the significant challenges posed by an aging fleet and the difficulty of acquiring modern replacements. Iran's combat aircraft fleet plays a significant role in reinforcing national security and military strategy, representing a merger of both indigenous development and foreign acquisitions, providing Iran with capabilities for air defense, ground attack, and strategic bombings.
