Arrow-3 has a significant advantage in terms of guidance, making it a better choice for engaging high-priority targets.

Warhead

Arrow-3 uses a hit-to-kill kinetic energy warhead, while Patriot PAC-2 GEM+ uses a 91 kg blast-fragmentation warhead with proximity fuse. Arrow-3's warhead is more effective against ballistic missiles, while Patriot PAC-2 GEM+ is more effective against aircraft and cruise missiles.
Arrow-3 has a significant advantage in terms of warhead effectiveness, making it a better choice for defending against ballistic missiles.

Scenario Analysis

Defending against Iranian ballistic missile salvo

In this scenario, Arrow-3 would be a better choice due to its ability to engage ballistic missiles at long range and with high precision. Patriot PAC-2 GEM+ would be less effective in this scenario due to its shorter range and less advanced guidance system.
Arrow-3

Defending against Houthi cruise missile attack

In this scenario, Patriot PAC-2 GEM+ would be a better choice due to its ability to engage cruise missiles with its blast-fragmentation warhead. Arrow-3 would be less effective in this scenario due to its inability to engage cruise missiles.
Patriot PAC-2 GEM+

Defending against Russian hypersonic missile attack

In this scenario, Arrow-3 would be a better choice due to its ability to engage hypersonic missiles at long range and with high precision. Patriot PAC-2 GEM+ would be less effective in this scenario due to its shorter range and less advanced guidance system.
Arrow-3

Complementary Use

Both Arrow-3 and Patriot PAC-2 GEM+ can be used in a layered defense architecture, with Arrow-3 providing long-range defense against ballistic missiles and Patriot PAC-2 GEM+ providing mid-range defense against aircraft and cruise missiles. This complementary use of both systems can provide a robust and effective defense against a wide range of threats.

Overall Verdict

Arrow-3 is a more advanced and effective missile defense system than Patriot PAC-2 GEM+, with a longer range, more advanced guidance system, and more effective warhead. However, Patriot PAC-2 GEM+ has a longer engagement time and is more effective against aircraft and cruise missiles. Ultimately, the choice between these two systems will depend on the specific needs and requirements of the defense architecture.
