2000-25: Iran Air Power.
Overview
Between 2000 and 2025, Iran’s air power displayed a persistent imbalance: a legacy manned force maintained through improvised sustainment, alongside a rapidly expanded missile, drone, and air-defence enterprise intended to deter and punish rather than to win air superiority. Operational outcomes underscore limited effectiveness in high-end air defence and limited capacity for external air support to aligned non-state partners. The June 2025 US strike on key nuclear facilities—executed without publicly evident defensive attrition—highlights the gap between Iran’s air-defence aspirations and performance.
Glossary of terms
• IRIAF: Islamic Republic of Iran Air Force, the conventional service operating most manned combat and transport aircraft.
• IRGC Aerospace Force: Revolutionary Guard organisation central to ballistic missiles, cruise missiles, and UAV strike capacity.
• IADS: Integrated air defence system linking sensors, command nodes, and surface-to-air missiles.
• Air superiority: The degree of control of the air that permits operations without prohibitive interference.
• SEAD/DEAD: Suppression/destruction of enemy air defences, a prerequisite for modern strike operations against capable opponents.
• Sortie generation: The ability to sustain high-tempo aircraft operations through maintenance, weapons, fuel, and crew cycles.
• Stand-off strike: Attacking from outside dense air-defence zones using missiles or UAVs.
• Proxy warfare: Pursuit of strategic goals through aligned non-state actors and indirect methods rather than direct state-on-state combat.
Key points
• Strategic choice and constraint: Iran’s air power development reflected both necessity and preference. Sanctions, limited finances, and restricted access to advanced aerospace supply chains made rapid modernisation of manned fleets difficult. Tehran therefore leaned into an approach that emphasised denial, survivability, and retaliation—seeking to complicate an attacker’s campaign design rather than to contest directly for air superiority in the classic sense.
• Manned aviation’s structural weakness: Iranian manned combat capability remained anchored in ageing aircraft, including US-origin types acquired before 1979 and subsequently sustained through overhaul, cannibalisation, and selective upgrades. This preserved limited air-policing and strike potential, but it constrained readiness, sensor quality, weapons integration, and survivability against modern opponents. The result was a force that could signal resolve but struggled to deliver decisive combat effects at scale.
• Readiness and training limitations: Modern air operations require sustained flying hours, complex composite training, robust maintenance depth, and dependable precision-munitions pipelines. Iran’s constraints reduced the likelihood of high-tempo, multi-axis sortie generation under threat. In practice, the gap between nominal inventory and usable combat mass shaped Iranian doctrine towards episodic employment and defensive alert routines rather than sustained offensive operations.
• Air defence as the centre of gravity: Iran prioritised ground-based air defence, dispersal, deception, and hardened infrastructure to reduce vulnerability to a first strike. This approach can create uncertainty and impose operational friction, but it depends on coherent sensor coverage, reliable command-and-control, and disciplined engagement under electronic and kinetic pressure. Performance against sophisticated strike packages remains the critical measure of whether denial investments translate into real protection.
• June 2025 as an empirical test: The US strike on Fordow, Natanz, and Esfahan in June 2025 provides the clearest contemporary indicator of Iranian air-defence limits. The attack achieved penetration and weapons delivery against strategic sites without publicly evident aircraft losses or clearly demonstrated defensive attrition. As an operational outcome, this represents failure to prevent attack and failure to impose visible cost—both central objectives of denial-focused air defence.
• Substitution with missiles and drones: Iran increasingly treated missiles and UAVs as its most credible instruments for deterrence by punishment. These systems offered scalable strike options, reduced dependence on vulnerable aircraft, and provided a means of saturation designed to stress defensive magazines and decision cycles. This substitution improved Iran’s retaliatory reach, but it also underlined limited confidence in manned aviation for contested, repeated precision operations.
• Limited external air support to partners: Iran did not employ its own manned air power to provide direct air support, air cover, or sustained aerial resupply for partners such as Hezbollah or Hamas. Geography, access, and escalation risk constrained such employment, but capability limitations also mattered: without modern tanking, battle management, and survivable strike platforms, Iran lacked a practical pathway to run classical air-support missions into heavily monitored and defended theatres.
• Proxy influence without air campaigns: Iranian support to aligned actors manifested primarily through training, material supply networks, rockets, missiles, UAV technology transfer, and advisory relationships rather than through Iranian squadrons executing air operations. This created real strategic effects, but it did not constitute “air power” in the sense of continuous ISR-led targeting, dynamic close support, or sustained air interdiction controlled by Iranian command structures.
• Operational effectiveness versus strategic rationality: A negative operational record does not automatically imply irrational strategy. Iran’s posture can be read as an attempt to “offset” conventional weakness by raising the prospective costs of intervention and by preserving retaliatory options under attack. Nonetheless, the test case of June 2025 suggests that the denial component did not perform at a level sufficient to protect the most politically sensitive fixed targets.
• Net assessment for 2000–25: The period is best characterised by persistent underperformance in manned air power and uneven performance in air defence, coupled with significant growth in missile and drone capacity. Iran’s “air power” influence therefore derived less from control of the air and more from stand-off punishment, saturation, and escalation management. Against a top-tier air force, outcomes indicate limited ability to prevent penetration or to impose attrition.
