Head-to-Head Analysis
Range & Coverage
Both Arrow-2 and THAAD have impressive range capabilities, with THAAD having a slightly longer range of 200 km compared to Arrow-2's 150 km. However, Arrow-2's higher speed and maneuverability make it a more effective system for intercepting shorter-range ballistic missiles. THAAD's AN/TPY-2 radar provides a 1000km detection range, giving it an advantage in terms of early warning and tracking.
THAAD has a slight advantage in terms of range and coverage, but Arrow-2's speed and maneuverability make it a better choice for shorter-range intercepts.
Accuracy
Both systems have high accuracy rates, with THAAD's hit-to-kill technology and Arrow-2's fragmentation warhead making them effective against a wide range of targets. However, Arrow-2's more advanced guidance system and higher speed give it a slight edge in terms of accuracy.
Arrow-2 has a slight advantage in terms of accuracy, but both systems are highly effective against a wide range of targets.
Cost
Arrow-2 is significantly cheaper than THAAD, with a unit cost of ~$2-3M per interceptor compared to THAAD's ~$11M per interceptor. However, THAAD's higher cost is offset by its longer range and more advanced capabilities.
Arrow-2 has a significant cost advantage, but THAAD's longer range and more advanced capabilities make it a better choice for certain scenarios.
Guidance
Arrow-2's active radar seeker with fragmentation warhead gives it a significant advantage in terms of guidance, allowing it to intercept a wide range of targets with high accuracy. THAAD's infrared seeker with hit-to-kill technology is also highly effective, but it has a slightly lower accuracy rate compared to Arrow-2.
Arrow-2 has a significant advantage in terms of guidance, making it a better choice for scenarios where high accuracy is critical.
Warhead
Arrow-2's directional fragmentation warhead gives it a significant advantage in terms of warhead effectiveness, allowing it to intercept a wide range of targets with high accuracy. THAAD's kinetic kill vehicle (no explosive) is also highly effective, but it has a slightly lower accuracy rate compared to Arrow-2.
Arrow-2 has a significant advantage in terms of warhead effectiveness, making it a better choice for scenarios where high accuracy is critical.
