What Happened
- The US-Israeli strike on Iran on February 28, 2026 and Iran's subsequent retaliatory missile and drone launches have brought missile defence systems to global attention.
- Israel's multi-layered air defence architecture — Iron Dome, David's Sling, Arrow-2, Arrow-3, and the newly operational Iron Beam laser system — was tested at a scale and intensity unprecedented in its history.
- US THAAD (Terminal High Altitude Area Defence) systems played a pivotal role in intercepting Iranian ballistic missiles; the US reportedly fired 100–150 THAAD interceptors during the conflict.
- US assessments suggest the overall interception efficiency was approximately 86%, though this declined as the conflict progressed due to more sophisticated Iranian missile variants.
- The sheer volume of interceptors consumed has raised significant concerns about US and Israeli stockpile sustainability and long replenishment timelines.
What Happened (continued)
- In addition to saving lives and property, missile defence systems serve a strategic deterrence function: they can dissuade adversaries from initiating conflict and buy decision-makers more time to respond diplomatically.
- The conflict has demonstrated both the strengths and the limits of missile defence — no system achieves 100% interception against mass saturation attacks.

Israel's Multi-Layered Missile Defence Architecture
Israel has built the world's most sophisticated multi-layered missile defence system, designed to intercept threats at every altitude and range category simultaneously. Each layer addresses a different threat profile.
Iron Dome (short range): Developed by Rafael Advanced Defence Systems with US funding, Iron Dome became operational in 2011. It is designed to intercept short-range rockets, artillery shells, and small drones at altitudes of 50 metres to 10 kilometres and ranges of 4–70 km. Each battery uses radar to track incoming threats, calculates interception probability, and only fires if the projectile would land in a populated area — a cost-savings mechanism given each interceptor costs approximately $40,000–$50,000.
David's Sling (medium range): Jointly developed by Raytheon (US) and Rafael (Israel), David's Sling bridges the gap between Iron Dome and Arrow. It intercepts medium- and long-range rockets, cruise missiles, and ballistic missiles with ranges up to 300 km at altitudes of 15–50 km. It became operational in 2017.
Arrow-2 and Arrow-3 (long range/exo-atmospheric): Developed by Boeing and Israel Aerospace Industries, Arrow-2 (operational 2000) intercepts ballistic missiles in the upper atmosphere. Arrow-3 (operational 2017) intercepts ballistic missiles outside the atmosphere (exo-atmospheric), at altitudes above 100 km — providing space-layer defense. Arrow-3 is specifically designed to counter Iranian Shahab and Khorramshahr-class ballistic missiles.
Iron Beam (directed energy): Israel declared Iron Beam, a ground-based high-energy laser system, fully operational in late 2025. It neutralizes small aerial threats (UAVs, mortars) by superheating them mid-air. Its key advantage is near-zero cost per interception (only electricity), compared to thousands of dollars per conventional interceptor.
- In the February 2026 conflict, THAAD interceptors accounted for almost half of all Iranian missile interceptions, indicating Arrow stockpiles were insufficient to handle the volume.
- Interception efficiency: 92% in the first week, dropping to 84% in the second week, and 75% on the final day — as Iran deployed more advanced missile variants and targeted urban areas.
- The US used approximately 25% of its total THAAD interceptor stockpile in the conflict; experts estimate 3–8 years to replenish at current production rates.
- A single THAAD interceptor costs approximately $10–15 million, compared to Iranian ballistic missiles costing $1–3 million each.
Connection to this news: The missile defence systems were the primary shield protecting Israeli and Gulf populations from Iranian retaliation. Their partial failure (approximately 14–25% of Iranian missiles penetrating defences at conflict's end) demonstrates that missile defence cannot be a complete substitute for diplomatic resolution.
THAAD: US Extended Deterrence and the India Connection
THAAD (Terminal High Altitude Area Defence) is a US Army land-based missile defence system designed to intercept and destroy ballistic missiles during their terminal (descent) phase at altitudes of 40–150 km. Developed by Lockheed Martin, THAAD uses "hit-to-kill" technology — no explosive warhead; the interceptor destroys the target through kinetic impact.
THAAD has been deployed by the US in South Korea (since 2017, amid North Korean missile threats), Guam, and Hawaii, and was deployed in Israel for the current conflict. The US has two operational THAAD batteries permanently assigned to Israel.
India's relevance: India has been in discussions with the US about acquiring advanced air defence systems. India currently operates the Russian S-400 Triumf system (5 squadrons contracted in 2018 for $5.43 billion), acquired despite US CAATSA (Countering America's Adversaries Through Sanctions Act) threats. India is also developing the indigenous Akash surface-to-air missile system (short-to-medium range) and DRDO's Advanced Air Defence (AAD) programme for ballistic missile defence.
- THAAD radar (AN/TPY-2) has a detection range of over 1,000 km — making it valuable for early warning as well as interception.
- Each THAAD battery has 8 launchers, 48 interceptors, and one fire control system.
- India's S-400 is Russia's equivalent of a combined David's Sling and Arrow-2 system in capability terms.
- India's deployment of S-400 has strained US-India relations but was ultimately not sanctioned under CAATSA — a compromise reflecting India's strategic importance to Washington.
Connection to this news: The massive consumption of US THAAD interceptors in the Israel-Iran conflict has direct implications for US extended deterrence commitments globally — including in the Indo-Pacific, where the US has commitments to South Korea, Japan, and Taiwan. Replenishing stocks will take years.
Missile Technology Control Regime (MTCR) and Proliferation Concerns
The Missile Technology Control Regime (MTCR) is a multilateral export control arrangement established in 1987 by G-7 nations (including India from 2016 onwards) to limit the proliferation of missiles and missile technology capable of delivering weapons of mass destruction. The MTCR covers rockets and unmanned air vehicles capable of delivering a payload of 500 kg to 300 km or beyond.
The conflict has renewed concerns about missile technology proliferation: Iran's missile programme, which is outside the MTCR, has been sharing technology with Houthi forces in Yemen, Hezbollah in Lebanon, and has sold Shahed-series drones to Russia for use in Ukraine. The sophistication of Iranian missiles used in the February 2026 strikes suggests continued development despite sanctions.
- India joined the MTCR as a full member in 2016, enabling access to advanced dual-use technologies.
- India and Israel have deep defence cooperation; Israel is India's second-largest defence supplier (after Russia).
- Israel's Arrow-3 system has been offered for export; Germany became the first export customer in 2023.
- The US and India are developing the Advanced Air Defence (AAD) system collaboratively under the DTTI (Defence Technology and Trade Initiative).
Connection to this news: The demonstrated effectiveness (and limitations) of missile defence systems will accelerate global demand for THAAD-equivalent systems, deepening US arms export relationships and complicating MTCR governance around dual-use missile technologies.
