Context:
Iran deployed the Sejjil ballistic missile for the first time in active combat during recent military operations, highlighting advancements in its missile technology and deterrence strategy.
Key Highlights:
Missile Characteristics & Development:
• Indigenous two-stage Medium Range Ballistic Missile (MRBM) developed by Iran
• Shift from liquid-fuel to solid-fuel technology for faster and reliable deployment
Technical Features:
• Range: ~2,000 km, covering Middle East and parts of Southeastern Europe
• Payload: ~700 kg warhead capacity
• Solid-fuel propulsion: Enables quick launch and long-term storage
• Two-stage design: Achieves high speed and altitude
Advanced Capabilities:
• Evasive maneuverability (“dancing missile”) makes interception difficult
• Guidance system: Combination of GPS + inertial navigation (Sejjil-2 variant)
• Designed to bypass missile defense systems like Iron Dome and Arrow
Strategic Significance:
• Represents shift toward high-survivability and rapid-response deterrence
• Hard to detect pre-launch and difficult to intercept mid-flight
• Indicates Iran’s transition from theoretical missile capability to operational deployment
Relevant Prelims Points:
• MRBM: Range between 1,000–3,000 km
• Solid vs Liquid Fuel:
- Solid fuel → faster launch, safer storage
- Liquid fuel → longer preparation time
• Two-stage missile: Uses sequential propulsion stages for extended range
• Inertial Navigation System (INS): Uses internal sensors for trajectory guidance
• Iron Dome/Arrow Systems: Israel’s missile defense systems
Relevant Mains Points:
• Regional Security Dynamics:
- Enhances Iran’s deterrence capability in West Asia
- Escalates arms race and missile proliferation concerns
- Technological Advancement:
- Indigenous development shows strategic autonomy in defense technology
- Increasing role of precision-guided and maneuverable missiles
- Implications for Global Security:
- Challenges existing missile defense systems
- Raises concerns about non-proliferation regimes (MTCR, NPT context)
- Way Forward:
- Strengthen global arms control mechanisms
- Promote regional diplomatic engagement and de-escalation
- Enhance missile defense and early warning systems globally
