Category: International Relations and Defence Technology

Sejjil, also spelt Sajjil, is an Iranian ballistic missile system. It is notable for its use of solid-fuel propulsion.

Key facts

  • Country: Iran.

  • Type: Medium-range ballistic missile.

  • Propulsion: Solid-fuel, two-stage design.

  • Solid-fuel missiles can generally be prepared for launch more quickly than comparable liquid-fuel systems that require extensive fuelling procedures.

  • The system is part of Iran's broader ballistic missile programme.

UPSC key pointers

  • Sejjil is associated with Iran, not Israel.

  • Solid-fuel propulsion can improve readiness and reduce pre-launch preparation time.

  • Ballistic missiles follow a largely ballistic trajectory during much of their flight.

  • Missile proliferation and regional deterrence are important international security concerns.
