What type of missile threats does the PAC-3 MSE primarily target?

The PAC-3 MSE (Patriot Advanced Capability-3 Missile Segment Enhancement) is designed as a highly capable missile defense system that targets a wide array of aerial threats, which includes both tactical and strategic missiles. This versatility is crucial in modern military operations where adversaries may deploy different types of missile systems, including short-range and long-range ballistic missiles, cruise missiles, and even advanced aerial threats.

The PAC-3 MSE features improved guidance and interception capabilities, which enhance its effectiveness against a diverse set of threats, ensuring that it can engage with various missile types effectively. This capability is fundamental for defense systems in hostile environments where multiple types of missiles may be used in attacks.

In contrast, the other options focus on more specific categories of threats. Some options suggest limitations to either ground-based threats like surface-to-air missiles or aerial threats like drones, which does not capture the full spectrum of the PAC-3 MSE's operational capabilities. The broad targeting ability of the PAC-3 MSE is what distinguishes it and makes the correct answer comprehensive in representing its mission profile.
