THAAD is part of what two systems?

• A. Integrated Air Defense System (IADS) and Theater Missile Defense System (TMDS)
• B. Ballistic Missile Defense System (BMDS) and Theater Missile Defense System (TMDS)
• C. Integrated Air Defense System (IADS) and Ballistic Missile Defense System (BMDS)
• D. Integrated Defense Network (IDN) and Ballistic Missile Defense System (BMDS)

Answer: (C)

THAAD is understood as part of both the Ballistic Missile Defense System and the Integrated Air Defense System. The Ballistic Missile Defense System is the overarching architecture that coordinates all ballistic-missile defense assets at the theater level, and THAAD contributes its terminal intercept capability within that broader BMDS framework. At the same time, THAAD is integrated into the theater’s air defense network—the Integrated Air Defense System—which connects radars, sensors, and weapons to provide coordinated battlespace awareness and command-and-control. This combination reflects how THAAD operates not in isolation but as a component of a unified defense posture that handles both ballistic threats and air-defense integration.
