THAAD
A U.S. Army theater ballistic-missile defense system designed to intercept short-, medium- and intermediate-range ballistic missiles inside and just outside the atmosphere in their terminal phase. It uses a hit-to-kill interceptor with no explosive warhead, destroying targets through kinetic impact alone.

Lifecycle cost (est.)
$2.5B – $3.5B
Acquisition is only ~30% of lifecycle cost, operating & support dominate over ~25 yrs. Rough 2.5–3.5× the unit price. Published studies put O&S anywhere from ~55% to ~70% of lifecycle cost depending on platform and method, which is why this is a band and not a single number. How we estimate this →

Overview
THAAD is the United States' dedicated upper-tier terminal defense: a hit-to-kill interceptor designed to destroy short- to intermediate-range ballistic missiles inside or just above the atmosphere, using nothing but kinetic impact. Its AN/TPY-2 X-band radar is one of the most powerful mobile radars ever fielded, able to track warheads at ranges commonly cited around 1,000 km and to cue other defenses across an entire theater. A battery's six launchers hold 48 ready interceptors, and THAAD's flight-test record, a long unbroken string of successful intercepts, is unmatched among ballistic-missile defenses.
The system's combat debut came in 2022, and the 2026 Iran war made it indispensable: US THAAD batteries in Israel and the Gulf engaged medium-range ballistic missiles alongside Arrow and Patriot in history's most intense missile-defense campaign. Post-ceasefire analyses focused less on hit rates than on magazine depth, interceptor expenditure ran far ahead of production, pushing THAAD stockpiles to the center of Washington's munitions-industrial debate.

| Max speed (Mach) Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters. | 8.24 Mach |
|---|---|
| Engagement range Maximum distance at which an air-defense system can intercept targets. Higher covers more airspace. | 200 km |
| Engagement altitude Maximum target altitude the system can reach. | 150,000 m |
| Simultaneous targets Number of targets the system can engage at once. Higher resists saturation attacks. | 24 |
Firepower
Armament, payload and guidance.
| Main armament Primary weapon: main gun, cannon or missile type. | THAAD hit-to-kill interceptor |
|---|---|
| Warhead type Blast-fragmentation, shaped charge (HEAT), penetrator, thermobaric or nuclear-capable. | Hit-to-kill kinetic (no explosive warhead) |
| Guidance How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire. | Inertial + infrared seeker homing |
Sensors & avionics
Radar, sensor suite and datalinks.
| Radar Primary radar. AESA (active electronically scanned array) is the current state of the art. | AN/TPY-2 X-band radar |
|---|---|
| Radar range Published detection range against a typical fighter-sized target. Higher sees first. | 1,000 km |
| Datalink Network connectivity: Link 16, MADL, national datalinks. Enables cooperative engagement. | Link 16, C2BMC |
Program
Cost, production scale and operators.
| Unit cost Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper. | $1,000,000,000 |
|---|---|
| Operator countries Number of countries operating the system. More operators means broader support ecosystem. | 5 |
