| Date | Result | Notes |
| 2005-11-22 | Success | Launched a missile in its first Flight EMD Test, known as FLT-01. The test was deemed a success by Lockheed and the Pentagon. |
| 2006-05-11 | Success | FLT-02, the first developmental flight test to test the entire system, including interceptor, launcher, radar, and fire control system. |
| 2006-07-12 | Success | FLT-03. Intercepted a live target missile. |
| 2006-09-13 | Aborted | Hera target missile launched, but had to be terminated in mid-flight before the launch of the FLT-04 missile. This has officially been characterized as a "no test".[citation needed] |
| Fall 2006 | Cancelled | FLT-05, a missile-only test, was postponed until mid-spring 2007.[citation needed] |
| 2007-01-27 | Success | FLT-06. Intercepted a "high endo-atmospheric" (just inside Earth's atmosphere) unitary (non-separating) target representing a "SCUD"-type ballistic missile launched from a mobile platform off Kauai in the Pacific Ocean. |
| 2007-04-06 | Success | FLT-07 test. Intercepted a "mid endo-atmospheric" unitary target missile off Kauai in the Pacific Ocean. It successfully tested THAAD's interoperability with other elements of the MDS system. |
| 2007-10-27 | Success | Conducted a successful exo-atmospheric test at the Pacific Missile Range Facility (PMRF) off Kauai, Hawaii. The flight test demonstrated the system's ability to detect, track and intercept an incoming unitary target above the Earth's atmosphere. The missile was hot-condition tested to prove its ability to operate in extreme environments. |
| 2008-06-27 | Success | Downed a missile launched from a C-17 Globemaster III. |
| 2008-09-17 | Aborted | Target missile failed shortly after launch, so neither interceptor was launched. Officially a "no test". |
| 2009-03-17 | Success | A repeat of the September flight test. This time it was a success. |
| 2009-12-11 | Aborted | FLT-11: The Hera target missile failed to ignite after air deployment, and the interceptor was not launched. Officially a "no test". |
| 2010-06-29 | Success | FLT-14: Conducted a successful endo-atmospheric intercept of unitary target at lowest altitude to date. Afterward, exercised Simulation-Over-Live-Driver (SOLD) system to inject multiple simulated targets into the THAAD radar to test system's ability to engage a mass raid of enemy ballistic missiles. |
| 2011-10-05 | Success | FLT-12: Conducted a successful endo-atmospheric intercept of two targets with two interceptors. |
| 2012-10-24 | Success | FTI-01 (Flight Test Integrated 01): test of the integration of THAAD with PAC-3 and Aegis against a raid of 5 missiles of different types. During this engagement THAAD successfully intercepted an Extended Long Range Air Launch Target (E-LRALT) missile dropped from a C-17 north of Wake Island. This marked the first time THAAD had intercepted a Medium Range Ballistic Missile (MRBM). Two AN/TPY-2 were used in the $180M test, with the forward-based radar feeding data into Aegis and Patriot systems as well as THAAD. |
| 2017-07-11 | Success | FTT-18 (Flight Test THAAD 18): The FTT-18 test plan was announced to the public on 8 July 2017. The first test of THAAD against an IRBM, FTT-18 successfully occurred on 11 July 2017; an Alaska-based THAAD interceptor, launched from the Pacific Spaceport Complex – Alaska on Kodiak island, intercepted its target over Alaska airspace. The FTT-18 target simulated an intermediate-range ballistic missile. It was "launched" near Hawaii from the cargo hold of a C-17, being initially dropped by parachute. From there the mock IRBM proceeded in a north-easterly direction until reaching Alaskan airspace, where it was intercepted. |
| 2017-07-30 | Success | FET-01 (Flight Experiment THAAD 01): In FET-01, the Missile Defense Agency (MDA) gathered threat data from a THAAD interceptor in flight. THAAD detected, tracked, and intercepted a medium-range ballistic missile (MRBM), which was launched from a C-17 by parachute. Soldiers from the 11th ADA Brigade conducted launcher, fire control, and radar operations without foreknowledge of the launch time. The MDA director, Lieutenant General Sam Greaves stated: "In addition to successfully intercepting the target, the data collected will allow MDA to enhance the THAAD weapon system, our modeling and simulation capabilities, and our ability to stay ahead of the evolving threat." |
