Head-to-Head Analysis
Range & Coverage
Iskander-M has a significantly shorter range compared to Shahab-3, which can reach up to 1300 km. However, Iskander-M's quasi-ballistic trajectory makes it more difficult to intercept. Shahab-3's longer range allows it to cover more territory, but its predictability makes it easier to defend against.
Shahab-3 has a significant advantage in terms of range and coverage, but Iskander-M's maneuverability makes it a more formidable opponent in close-range engagements.
Accuracy
Iskander-M has a more advanced guidance system, which allows it to achieve higher accuracy compared to Shahab-3. However, Shahab-3's later variants have shown improved accuracy with maneuvering warheads. In a head-to-head engagement, Iskander-M's accuracy would give it an edge, but Shahab-3's improved variants would make it a closer contest.
Iskander-M has a slight advantage in terms of accuracy, but Shahab-3's improved variants would make it a competitive opponent.
Cost
Shahab-3 is estimated to be significantly cheaper than Iskander-M, with a unit cost of around $1-2M compared to Iskander-M's $3M. However, Iskander-M's advanced technology and maneuverability make it a more valuable asset in the long run.
Shahab-3 has a significant cost advantage, but Iskander-M's advanced technology and maneuverability make it a more valuable asset in the long run.

Iskander-M has a slight advantage in terms of speed, but Shahab-3's improved variants would make it a competitive opponent.
Guidance
Iskander-M has a more advanced guidance system compared to Shahab-3, which allows it to achieve higher accuracy and maneuverability. However, Shahab-3's later variants have shown improved guidance with GPS/INS and maneuvering reentry vehicles.
Iskander-M has a significant advantage in terms of guidance, but Shahab-3's improved variants would make it a competitive opponent.
Scenario Analysis
Defending against Iranian ballistic missile salvo
In a scenario where Iran launches a salvo of Shahab-3 missiles, Iskander-M's advanced guidance system and maneuverability would make it a more formidable opponent. However, Shahab-3's longer range and larger warhead capacity would allow it to cover more territory and cause more damage.
Iskander-M
Attacking a heavily defended target
In a scenario where Iskander-M is used to attack a heavily defended target, its advanced guidance system and maneuverability would allow it to penetrate the defenses and achieve a high degree of accuracy. However, Shahab-3's larger warhead capacity and longer range would allow it to cause more damage and penetrate deeper into the target area.
Iskander-M
Launching a surprise attack
In a scenario where Shahab-3 is used to launch a surprise attack, its longer range and larger warhead capacity would allow it to catch the enemy off guard and cause significant damage. However, Iskander-M's advanced guidance system and maneuverability would allow it to adapt to changing circumstances and achieve a high degree of accuracy.
Shahab-3
Complementary Use
Iskander-M and Shahab-3 can be used in complementary ways to achieve a higher degree of effectiveness. For example, Iskander-M can be used to attack high-priority targets, while Shahab-3 can be used to attack secondary targets and cause widespread damage. By combining these two systems, a military can achieve a higher degree of flexibility and adaptability.
Overall Verdict
Iskander-M and Shahab-3 are both formidable ballistic missiles with unique strengths and weaknesses. Iskander-M's advanced guidance system and maneuverability make it a more formidable opponent in close-range engagements, while Shahab-3's longer range and larger warhead capacity make it a more effective opponent in long-range engagements. Ultimately, the choice between these two systems depends on the specific needs and circumstances of the military.
