The geopolitical landscape of the Middle East has been fundamentally reconfigured during the ongoing high-intensity conflict. This report provides an exhaustive technical analysis of the Islamic Republic of Iran’s military arsenal, documenting the transition from a pre-war posture of asymmetric deterrence to a post-conflict state of significant material degradation. The analysis encompasses the dual-structured military system, comprising the regular Islamic Republic of Iran Army (Artesh) and the Islamic Revolutionary Guard Corps (IRGC), evaluating their combined capabilities across ballistic missiles, unmanned aerial systems (UAS), naval assets, air defense networks, and ground forces. As of March 2026, the Iranian military operates under the supreme command of Mojtaba Khamenei, following the death of the previous leader, with the Ministry of Defence and Armed Forces Logistics (MODAFL) and the General Staff overseeing a force of approximately 610,000 active personnel and 350,000 reserves.
The Economic and Strategic Foundation of Iranian Defense
The resilience of the Iranian defense industry is rooted in a decades-long pursuit of self-sufficiency, catalyzed by international sanctions that were most recently intensified through the “snapback” mechanism in late September 2025. This industrial base, centered around the Aerospace Industries Organization (AIO) and the Marine Industries Organization (MIO), has prioritized mass-producible, low-cost technologies that exploit the cost-asymmetry of modern warfare. For the 2025-2026 fiscal year, the Iranian defense budget reached an estimated $7.9 billion, representing approximately 12% to 20% of total government expenditure, a significant allocation despite persistent economic volatility and currency devaluation.
This financial commitment allowed for the rapid replenishment of the ballistic missile and drone programs following the “Twelve-Day War” of June 2025. By the onset of “Operation Roaring Lion” and “Operation Epic Fury” in February 2026, Iran had entered the conflict with a rebuilt arsenal of approximately 2,500 ballistic missiles and thousands of unmanned systems. The strategic doctrine underpinning this build-up was “deterrence through cost-imposition,” a theory tested by the sheer scale of ammunition expenditure observed in early 2026.
Ballistic and Cruise Missile Capabilities: The Strategic Deterrent
Iran’s missile program is the cornerstone of its military power, providing long-range strike capabilities that compensate for its lack of a modern air force. The arsenal is categorized by range, propellant type, and guidance sophistication, with a distinct shift toward solid-fueled precision-guided munitions (PGMs) observed in the last five years.
Short-Range Ballistic Missiles (SRBM): Tactical Dominance
The SRBM inventory (ranges 300 km to 1,000 km) is the most frequently deployed component of the IRGC Aerospace Force. These systems allow for rapid theater-wide strikes against regional bases and maritime targets.
SRBM Inventory, Unit Costs, and Attrition (as of March 2026)
| Missile System | Type/Propellant | Range (km) | Estimated Unit Cost (USD) | Usage/Attrition (2026 Conflict) | Status (Remnant) |
|---|---|---|---|---|---|
| Fateh-110 | Solid | 300 | $110,000 – $2,100,000 | Over 1,200 fired; 60% of launchers lost | Approx. 400 units |
| Fateh-313 | Solid | 500 | Over $1,500,000 | Extensively used in strikes on Gulf bases | Severely Depleted |
| Zolfaghar | Solid | 700 | Approx. $150,000 | Fired in waves against UAE/Kuwait | Approx. 200 units |
| Qiam-1 | Liquid | 750 | Approx. $3,500,000 | Used in early volleys; high site attrition | Negligible |
| Shahab-1/2 | Liquid | 350-750 | Under $1,000,000 | Mostly expended as “saturation” fire | Phasing Out |
| Hormuz-1/2 | Solid (Anti-ship) | 300 | Approx. $250,000 | Used against US Navy Fifth Fleet | Approx. 50 units |
The Fateh-110 family remains the most technologically significant SRBM, with the $2.1 million upper-tier cost reflecting the integration of anti-radiation or electro-optical terminal seekers. During the first ten days of “Operation Roaring Lion” in February 2026, Iran expended 2,410 ballistic missiles, a rate nearly four times higher than the entirety of the June 2025 war. This rapid depletion was a deliberate attempt to overwhelm the “Regional Air Defense” framework, particularly in the UAE and Kuwait, which absorbed 48% and 18.4% of total projectiles respectively.
Medium-Range Ballistic Missiles (MRBM) and Hypersonic Ambitions
Iran’s MRBMs (ranges 1,000 km to 3,000 km) provide the capability to strike Israel, Southern Europe, and the entirety of the Arabian Peninsula from hardened underground “missile cities”.
MRBM Technical Specifications and Strategic Deployment
| Missile System | Range (km) | Payload (kg) | Propellant | Strategic Note |
|---|---|---|---|---|
| Shahab-3 | 1,300 | 1,200 | Liquid | Legacy system; carries nuclear-capable payload |
| Ghadr-110 | 1,950 | 800 | Liquid | Extended range variant of Shahab-3 |
| Sejjil-2 | 2,000 | 1,000 | Solid | Hardest to intercept due to rapid launch cycle |
| Khorramshahr | 2,000 | 1,800 | Liquid | High-mass payload; MIRV-capable claims |
| Emad | 1,700 | 750 | Liquid | Precision-guided maneuverable reentry vehicle |
| Fattah-1/2 | 1,400-1,500 | 450 | Solid | Reported Hypersonic Glide Vehicle (HGV) |
| Haj Qasem | 1,400 | 800 | Solid | Named for Qassem Soleimani; precision strike |
The development of the Fattah-1 and Fattah-2 hypersonic missiles represents Iran’s attempt to bypass advanced Terminal High Altitude Area Defense (THAAD) and Patriot (PAC-3) batteries. Reports indicate these missiles can reach speeds of Mach 13 to 15, although their operational effectiveness in the February 2026 strikes was limited by the systematic destruction of their specialized mobile launchers.
Operational Status of the Missile Force (March 2026)
The 2026 conflict witnessed the most concentrated aerial campaign against Iranian missile infrastructure in history. By Day 10 of “Operation Roaring Lion,” the following status was confirmed by IDF and CENTCOM intelligence:
Launch Rate Degradation: Ballistic missile attacks declined by 90% from the opening day (480 missiles) to the tenth day (fewer than 10 missiles).
Launcher Attrition: Over 60% of Iran’s mobile transporter erector launchers (TELs) were destroyed. Estimates of remaining active launchers range from 100 to 120, down from a pre-war peak of over 300.
Industrial Base Damage: Precision strikes on the Parchin Military Complex and the Khojir Missile Production Complex destroyed two to three solid propellant production facilities. This has rendered the replenishment of solid-fueled missiles like the Sejjil and Kheybar Shekan “negligible” for the foreseeable future.
Supply Chain Interdiction: Iran remains dependent on external sources for chemical precursors. In February 2025, a 1,000-ton shipment of sodium perchlorate (sufficient for 260 Kheybar Shekan missiles) was identified at Bandar Abbas, highlighting the critical role of Chinese front companies in sustaining Iranian production.
Unmanned Aerial Systems (UAS): The Global Proliferator
The Iranian drone program has emerged as a primary instrument of Iranian power projection, with thousands of units exported to Russia for use in the Ukraine theater and disseminated to regional proxies like the Houthis and Hezbollah.
The Shahed Family: Loitering Munition Excellence
The Shahed-136, and its smaller variant the Shahed-131, are the defining weapons of contemporary asymmetric warfare. Their airframes, constructed from carbon fiber cloth and honeycomb materials, are designed for simplicity and mass production.
UAV Technical Profile and Economic Valuation
| Drone Model | Type | Range (km) | Speed (km/h) | Unit Cost (Est. USD) |
|---|---|---|---|---|
| Shahed-131 | Loitering Munition | 900 | 185 | $2,000 – $4,000 |
| Shahed-136 | Loitering Munition | 2,000 | 185 | $7,000 – $20,000 |
| Shahed-238 | Jet-powered Strike | 1,000 | 500+ | Approx. $50,000 |
| Mohajer-6 | MALE ISR/Strike | 200 | 200 | Approx. $250,000 |
| Ababil-3 | ISR/Tactical | 120 | 300 | Approx. $50,000 |
| Kaman-22 | MALE Strategic | 3,000 | 200 | Approx. $1,500,000 |
The cost-exchange ratio for these systems is heavily skewed in Iran’s favor. While a Shahed-136 can be produced for as little as $7,000 (based on Iranian domestic manufacturing math comparing tractor production costs), the interceptors used to down them — such as the Patriot PAC-3 or THAAD — cost between $3 million and $15 million per shot. During the first ten days of the 2026 war, Iran fired 3,560 drones, forcing the US and its allies to expend an estimated $1.66 billion in air defense munitions.
Strategic Impact of UAS Operations
Saturation Tactics: Iran used drones to “mask” its ballistic missile launches, forcing air defenses to engage cheap UAVs while higher-value targets were in transit.
Maritime Range Projection: The development of drone carriers, such as the IRIS Shahid Bagheri, was intended to allow Iran to project drone strikes at intercontinental ranges. However, the Shahid Bagheri was destroyed in the opening 48 hours of “Operation Epic Fury” on February 28, 2026.
Regional Interception Rates: Despite the volume, interception rates remained high. Israel and the UAE reported interception rates of 90% and 93% respectively for Iranian drones.
Status of Stockpiles: Estimates suggest Iran has expended or lost on the ground over 80% of its strategic UAV inventory (Shahed-131/136/238) as of March 2026.
Naval Forces: The Split Doctrine
Iran maintains two distinct naval forces: the Islamic Republic of Iran Navy (IRIN), responsible for blue-water operations, and the Islamic Revolutionary Guard Corps Navy (IRGCN), specialized in asymmetric coastal warfare and “swarm” tactics.
Islamic Republic of Iran Navy (IRIN) Inventory and Attrition
The IRIN was the primary target of “Operation Epic Fury,” intended to eliminate Iran’s ability to project power into the Gulf of Oman and the Indian Ocean.
IRIN Major Combatants (Pre-Conflict vs. March 2026)
| Vessel Class | Pre-War Count | Status (Post-March 2026) | Technical Note |
|---|---|---|---|
| Moudge-class (Frigate) | 4 | 3 Sunk / 1 Damaged | Domestically built; includes Jamaran |
| Alvand-class (Frigate) | 3 | All 3 Sunk/Disabled | British-built hulls from 1960s/70s |
| Bayandor-class (Corvette) | 2 | Both Sunk | US-built legacy vessels |
| Kilo-class (Submarine) | 3 | 1 Confirmed Damaged | Russian SSK; capable of cruise missiles |
| Ghadir-class (Midget sub) | 20+ | 5 Sunk in harbor | Specialized for shallow water/Strait |
| Makran (Forward Base) | 1 | Struck/Immobilized | Converted 121,000-ton tanker |
On March 1, 2026, U.S. President Donald Trump announced that nine major IRIN vessels were sunk in a single 48-hour window. CENTCOM corroborated this by claiming the destruction of all 11 Iranian ships located in the Gulf of Oman, including those at the Konarak and Bandar Abbas naval bases. The IRIN’s surface combat capacity has effectively been reduced by 85%.
IRGCN: The Asymmetric Threat
The IRGCN operates a fleet of hundreds, potentially thousands, of fast-attack craft and speedboats. These vessels prioritize speed and numbers over individual survivability.
Missile Boats: Includes 10 Houdong, 25 Peykaap II, and 10 MK13 boats armed with anti-ship cruise missiles (ASCMs).
Shahid Soleimani-class: Two stealthy catamaran corvettes received in 2024. One was reportedly targeted and sunk near the Strait of Hormuz in late February 2026.
Fast Speedboats: New variants reaching speeds of 126.6 mph, equipped with ASCMs, remain the most significant surviving threat to maritime traffic in the Strait of Hormuz.
Seizures: Even under fire, the IRGCN attempted to intercept commercial traffic, as seen with the seizure of the Marshall Islands-flagged tanker Talara on November 14, 2025, in retaliation for shadow fleet losses.
Integrated Air Defense Systems (IADS): The Failed Shield
The collapse of the Iranian IADS during the 2026 conflict highlighted a critical failure in the integration of legacy Russian hardware and modern indigenous designs. Despite claims of a “layered” defense, coalition aircraft achieved near-total air superiority within 24 hours of the conflict’s start.
Air Defense Inventory and Status
| System | Origin | Range (km) | Status (March 3, 2026) |
|---|---|---|---|
| S-300PMU-2 | Russia | 200 | 80% Destroyed/Non-Functional |
| Bavar-373 | Iran | 300 | Severely Degraded; Radars targeted |
| Khordad-15 | Iran | 150 | 60% Destroyed |
| 3rd Khordad | Iran | 105 | Multiple units lost |
| Tor-M1/Pantsir | Russia | 12-15 | Intermittent; active in point defense |
| Mersad (HAWK) | Iran/USA | 40 | Legacy; vulnerable to EW |
The Bavar-373, Iran’s flagship domestic SAM system, was designed to track up to 200 targets simultaneously using the Meraj-4 phased array radar. However, analysts observed that Iranian operators often had to increase radar power output to overcome coalition electronic warfare (EW), which inadvertently revealed their positions to AGM-88 anti-radiation missiles.
Radar and Command Infrastructure Attrition
Strategic Blindness: Three major radar systems were confirmed destroyed by March 3, including a Matla-ol-Fajr installation.
Strategic Radar Loss: The AN/FPS-132 Early Warning Radar in Qatar and the AN/TPY-2 radar of the THAAD battery in the UAE were damaged by Iranian missile strikes, but the coalition’s overall detection network remained intact, whereas Iran’s indigenous radar network suffered systemic failure.
Command Neutralization: CENTCOM confirmed the destruction of the Iranian Regime’s Leadership Compound and central headquarters in the opening phase of the 2026 campaign.
Ground Forces: The Conventional Mosaic
The Iranian Land Forces (Artesh and IRGC Ground Force) maintain a massive inventory that blends Cold War-era Western platforms with reverse-engineered Soviet designs and modern local modernizations.
Main Battle Tanks (MBTs) and Light Tanks
The total combat tank count for Iran is estimated at 1,500 units, although operational readiness varies widely across classes.
Armored Inventory Breakdown (March 2026)
| Tank Model | Category | Units | Technical Features |
|---|---|---|---|
| Karrar | MBT (Modern) | 100 | 125mm smoothbore; ERA; laser rangefinder |
| T-72S | MBT (Modern) | 480 | Produced in Iran; 125mm gun |
| Zulfiqar-1/3 | MBT (Modern) | 250 | Indigenous; Abrams/Patton influence |
| T-72Z Safir-74 | MBT (Legacy) | 400 | T-55 chassis; 105mm gun |
| Chieftain/Mobarez | MBT (Legacy) | 200 | British origin; upgraded locally |
| M60A1/Samsam | MBT (Legacy) | 150 | US origin; upgraded locally |
| FV101 Scorpion | Light Tank | 280 | British origin; 90mm gun |
The Karrar remains the most capable Iranian tank, featuring explosive reactive armor (ERA) and an autoloader similar to the T-90MS. However, production has been slow, with only 100 units operational out of a planned 800. In the 2026 conflict, ground forces have seen limited deployment as the war has remained primarily in the aerospace and maritime domains, though attrition of towed artillery and rocket systems has been noted in the border regions.
Infantry Fighting Vehicles (IFVs) and APCs
Iran maintains a fleet of 2,682 IFVs/APCs, designed to facilitate a mobile defense-in-depth.
Makran: 480 units. This is a modernization of the Soviet BTR-50 with a remote weapon station (RWS) and enhanced armor.
BMP-2: 400 units. The workhorse of the IRGC armored corps, acquired post-Soviet collapse.
Boragh: 240 units. An Iranian modernization of the BMP-1, featuring a 30mm autocannon and ATGM launchers.
M113A1: 305 units. Pre-1979 US-supplied tracked carriers.
Artillery and Rocket Systems
Iran’s artillery branch is one of its most potent conventional assets, featuring approximately 7,000 systems in total.
Self-Propelled: 103 units, including the North Korean M1978 “Koksan” (170mm) and indigenous Raad-1 (122mm).
Towed Artillery: 126 units plus over 2,130 mortars of various calibers (37mm to 160mm).
MLRS: 155 units of the BM-21 Grad and 90 units of local designs (Azrash/Hadid/Fajr-5). The Fajr-5, with its 330mm rockets, has been used extensively by proxies to strike deep into regional territory.
The Strategic Balance: Attrition vs. Sustainability
The “Operation Roaring Lion” campaign has demonstrated that while Iran’s mass-production of asymmetric weapons can impose a high financial cost on its adversaries, the infrastructure supporting these weapons is vulnerable to sustained high-intensity strikes.
Comparison of War Intensities: June 2025 vs. February 2026
| Metric | June 2025 (12 Days) | Feb 2026 (10 Days) | Scaling Factor |
|---|---|---|---|
| Ballistic Missiles Fired | 627 | 2,410 | 3.8x |
| Drones Fired | 735 | 3,560 | 4.8x |
| Iranian Naval Vessels Lost | 5-10 | 43 | 4.3x |
| Daily Fire Rate (Peak) | 100/day | 480/day | 4.8x |
| US Daily Cost (Peak) | Approx. $200M | $1.1B – $2B | 5.5x |
The “terminal” trajectory of Iranian fire rates in March 2026 suggests that Iran has exhausted its ready-to-launch stockpiles and is now reliant on a shattered production base. The destruction of the Parchin and Shiraz electronics zones has specifically targeted the “brain” of the Iranian missile program — the guidance and radar systems — rendering even the surviving hulls of SRBMs and MRBMs difficult to deploy effectively.
Remnant Arsenal Summary (March 2026)
Missiles: Approximately 500-1,500 ballistic missiles of varying ranges remain in storage, but fewer than 120 mobile launchers are operational.
Drones: Strategic OWA inventory (Shahed-136) is estimated to be below 15% of pre-war levels. Tactical drone production continues in decentralized facilities.
Navy: Blue-water IRIN is non-existent. IRGCN fast-attack craft remain a potent threat for hit-and-run attacks in the Persian Gulf.
Air Defense: 80% of long-range systems are non-functional. The network has devolved into isolated point defenses.
Ground Forces: Largely intact as a conventional force, but severely degraded in terms of logistical support and air cover.
Technical Audit of Material Costs and Economic Burden
The 2026 conflict is the most expensive air campaign in the region’s history, with the “cost-per-kill” ratio favoring Iran’s asymmetric platforms even in their destruction.
Coalition Munition Expenditure and Unit Costs
| Munition / Platform | Unit Cost (USD) | Number Expended (H+100) | Total Cost (USD) |
|---|---|---|---|
| Tomahawk (TLAM) | $3,600,000 | 168 | $609,800,000 |
| JASSM (Air-launched) | $3,500,000 | 56 | $198,500,000 |
| PAC-3 MSE (Patriot) | $3,900,000 | 64 | $249,600,000 |
| THAAD Interceptor | $12,400,000 | 24 | $297,600,000 |
| SM-3 (Aegis) | $25,400,000 | 24 | $609,600,000 |
| JDAM Kit | $38,000 | 1,988 | $166,900,000 |
The total munitions cost for the first 100 hours was estimated at $3.1 billion. This highlights the fundamental challenge of countering Iran’s arsenal: while Iran’s $4,000 drones are being destroyed, the coalition is spending millions per interception. The economic “terminal” state is not just for Iran’s inventory, but potentially for the sustainability of Western-style air defense in a protracted conflict.
Final Inventory Assessment and Strategic Outlook
The Iranian arsenal as of March 2026 is a shadow of its 2024 posture, yet it remains dangerous due to its decentralized nature and the survivability of its “missile city” architecture. The transition from 480 launches per day to fewer than 10 confirms that the conventional, high-intensity phase of Iranian military operations has collapsed. However, the persistence of over 100 mobile launchers and the survivability of IRGCN speedboats ensure that Iran retains a “guerrilla” naval and missile capability.
The primary constraint for Iran moving forward is the replenishment of high-tech components. With the snapback of UN sanctions and the physical destruction of the Shiraz Electronics Industries and Parchin complexes, the technological gap between Iran and the coalition is expected to widen rapidly. The 2026 conflict has effectively dismantled the Iranian “Shield” (IADS) and “Spear” (IRIN/MRBMs), leaving only the “Swarm” (UAS/IRGCN) as a viable but degraded operational tool.
As regional traffic in the Strait of Hormuz remains suppressed and oil prices fluctuate around $80 per barrel, the remnants of Iran’s arsenal — particularly its mines and short-range ASCMs — continue to dictate the economic security of the Gulf, even if their strategic military utility has been broken.
