Exoatmospheric Interception
100+ km altitudeIntercept above the atmosphere before warhead reentry. Eliminates the risk of debris and toxic payloads over populated areas. Requires detection at extreme range and closing velocities exceeding Mach 10.
Arrow-3 100+ km altitude Exo-atmospheric hit-to-kill — intercept in space before reentry Israel (IAF)
THAAD 40–150 km altitude Terminal high-altitude hit-to-kill kinetic intercept US (Army)
Aegis BMD Exo + Endo Sea-based mid-course and terminal BMD (SM-3 / SM-6) US (Navy)
Arrow-3
Exo-Atmospheric BMD (Space) — Top Layer
- Interceptor Arrow-3 (hit-to-kill, kinetic)
- Range 100+ km
- Altitude 100+ km (intercept in space)
- Targets Long-range and intermediate ballistic missiles
- Radar Green Pine
- First combat Round 2 (Oct 2024)
Intercepts above the atmosphere before warhead reentry, eliminating the risk of debris over populated areas. First combat use in Round 2 against Iranian MRBMs.
THAAD
Terminal High-Altitude BMD
- Interceptor THAAD (hit-to-kill, kinetic)
- Range 200+ km
- Altitude 40–150 km
- Targets Short- and medium-range ballistic missiles
- Radar AN/TPY-2 (X-band)
- Deployed US Army battery in Israel since 2024
US-operated battery deployed to Israel. Bridges the gap between Arrow-3 exo-atmospheric and Arrow-2 upper-endo intercepts. Full THAAD deep-dive →
Aegis BMD
Sea-Based Ballistic Missile Defence
- Interceptor SM-3 (exo) / SM-6 (endo + terminal)
- Altitude Exo-atmospheric (SM-3) + endo (SM-6)
- Platform Arleigh Burke-class destroyers, Ticonderoga cruisers
- Operator US Navy
Provides forward-deployed BMD from the Eastern Mediterranean and Red Sea. SM-3 intercepts in space; SM-6 handles terminal-phase and cruise missile threats.
Endoatmospheric Interception
0–60 km altitudeIntercept within the atmosphere — from the upper stratosphere down to ground level. These systems handle the highest volume of engagements and form the backbone of area defence over Israeli population centres.
Arrow-2 40–60 km altitude Upper endo-atmospheric blast-fragmentation intercept Israel (IAF)
David's Sling Up to ~15 km alt Medium-range Stunner dual-seeker interceptor Israel (IAF)
Patriot PAC-3 Up to ~24 km alt Medium-range hit-to-kill air and missile defence US, SA, UAE
Iron Dome Up to ~10 km alt Short-range Tamir interceptor — highest volume Israel (IAF)
Arrow-2
Upper Endo-Atmospheric BMD
- Interceptor Arrow-2 (blast-fragmentation warhead)
- Range ~90–150 km
- Altitude 40–60 km
- Targets Medium-range ballistic missiles
- Radar Green Pine (L-band)
- Operational Since 2000
First Israeli dedicated BMD system. Intercepts incoming ballistic missiles in the upper atmosphere before reentry. Uses blast-fragmentation rather than direct hit-to-kill.
David's Sling
Medium-Range BMD
- Interceptor Stunner (two-stage, dual seeker: radar + electro-optical)
- Range 40–300 km
- Altitude Up to ~15 km
- Targets TBMs, cruise missiles, large rockets
- Operational Since 2017
- Partner Co-developed with Raytheon
Bridges the gap between Iron Dome and Arrow. Designed to defeat salvos of ballistic missiles and cruise missiles that fly beyond Iron Dome's ceiling.
Patriot PAC-3
Medium-Range Air & Missile Defence
- Interceptor PAC-3 MSE (hit-to-kill)
- Range ~70 km
- Altitude Up to ~24 km
- Targets TBMs, cruise missiles, aircraft
- Operators US, Saudi Arabia, UAE
Widely deployed across the region by US and Gulf states. Provides overlapping coverage with David's Sling. PAC-3 MSE variant has enhanced manoeuvrability for ballistic missile engagement.
Iron Dome
Short-Range Air Defence (SHORAD)
- Interceptor Tamir
- Range 4–70 km
- Altitude Up to ~10 km
- Targets Rockets, artillery, mortars, cruise missiles, drones
- Batteries ~10 deployed
- Success rate ~90% historically
Workhorse of Israeli defence. Handles the highest volume of intercepts. Each battery has 3–4 launchers with 20 Tamir interceptors each.
Performance Across Rounds
| Round | Interception Rate | Key Defence Events |
|---|---|---|
| Round 1 (Apr 2024) | ~99% | Coalition-wide defence; first major combined intercept operation against mixed ballistic missile and drone salvo |
| Round 2 (Oct 2024) | ~85–90% | Ballistic missile-only attack; some impacts at Nevatim Airbase; Arrow-3 first combat use |
| Round 3 (Jun 2025) | ~86% | Sustained 12-day campaign; interceptor attrition became a strategic concern; multi-layer engagement sequences |
| Round 4 (Feb 2026–) | TBD (ongoing) | Multi-theatre campaign; THAAD and Aegis BMD playing larger role alongside Israeli layers |
Cost-Exchange Ratio
The Economics of Defence at Scale
One of the central strategic challenges of sustained Iranian strike campaigns is the cost asymmetry between Iran's cheap munitions and Israel's interceptors. Firing a $100K Tamir missile to destroy a $25K Shahed drone is economically unfavourable at scale. Iron Beam's near-zero cost per shot addresses this problem, particularly against drone swarms.
Iron Dome vs Shahed-136
Tamir: $50–100K vs Shahed-136: $20–50K
Arrow-3 vs MRBM
Arrow-3: $2–3M vs BM: $500K–2M
Iron Beam vs Drone
Laser: ~$0 (electricity) vs Drone: $20–50K
