Target entity: AN/SPY-1D(V) phased array radar
Context triple: [Hobart-class destroyer, hasRadar, AN/SPY-1D(V) phased array radar]

A. AN/SPY-1F radar
The AN/SPY-1F radar is a compact, multi-function, phased-array naval radar system used on smaller warships for advanced air and missile defense.
B. AN/TPY-2 radar
The AN/TPY-2 radar is a high-resolution, X-band, phased-array missile defense radar used for detecting, tracking, and discriminating ballistic missile threats.
C. AN/APY-2 radar
The AN/APY-2 radar is an advanced airborne early warning and control (AEW&C) radar system designed to provide long-range surveillance, tracking, and battle management capabilities.
D. AN/MPQ-65 radar
