Head-to-Head Analysis
Range & Coverage
Sejjil has a significantly longer range than Shahab-3, allowing it to reach all of Israel and US bases in the Gulf. This makes Sejjil a more suitable choice for targeting distant areas. However, Shahab-3's larger warhead capacity and proven track record make it a better option for high-priority targets.
Sejjil is better for range and coverage due to its longer range, but Shahab-3 is better for high-priority targets due to its larger warhead capacity.
Accuracy
Shahab-3 has a more accurate guidance system, particularly with its later variants featuring GPS/INS and maneuvering reentry vehicles. This makes Shahab-3 a more reliable choice for precision strikes. Sejjil's accuracy is reportedly lower, but its solid-fuel design allows for faster launch times.
Shahab-3 is better for accuracy due to its more advanced guidance system, but Sejjil's faster launch times make it a better option for rapid response scenarios.
Cost
Shahab-3 is estimated to be significantly cheaper than Sejjil, with a unit cost of around $1-2 million compared to Sejjil's $3-5 million. This makes Shahab-3 a more cost-effective option for large-scale deployments.
Shahab-3 is better for cost due to its lower unit cost, making it a more suitable choice for large-scale deployments.
Speed
Sejjil has a significantly higher speed than Shahab-3, reaching Mach 10+ at burnout compared to Shahab-3's Mach 7. This makes Sejjil a more suitable choice for rapid response scenarios and high-priority targets.
Sejjil is better for speed due to its higher speed, making it a more suitable choice for rapid response scenarios and high-priority targets.
Survivability
Sejjil's solid-fuel design allows it to be launched quickly and hide fueled, making it a more survivable option. Shahab-3's liquid-fuel design requires hours of fueling, making it more vulnerable to preemptive strikes.
Sejjil is better for survivability due to its solid-fuel design and faster launch times, making it a more suitable choice for high-priority targets and rapid response scenarios.
Scenario Analysis
Defending against Iranian ballistic missile salvo
In a scenario where Iran launches a ballistic missile salvo, Sejjil's longer range and higher speed make it a more suitable choice for targeting distant areas. However, Shahab-3's larger warhead capacity and proven track record make it a better option for high-priority targets.
