That is also the possible reason Iran has only used their Sejil missiles once. They are waiting to soften defenses first. AI Overview The Iranian "dancing missile" is the Sejjil (or Sejil/Sajjil-2), an advanced, solid-fuel, medium-range ballistic missile. It earned this nickname due to its high-altitude maneuverability, which allows it to change trajectory and "dance" to evade defense systems like the Iron Dome, making it difficult to intercept. Key details about the Sejjil include: Performance: It has a reported range of up to 2000 –2500 km and a high, fast flight path, notes the Wikipedia article. Technology: Being a solid-fuel missile, it can be launched much faster than older, liquid-fuel systems, such as the Shahab. Use: It is designed to strike distant targets while defying interception through erratic, "zigzag" flight, says this post on Facebook. Range: The missile is designed to hit targets up to 2000 km away, according to this MSN article. The Sejjil is part of Iran's strategy to enhance long-range capabilities with solid-fuel technology.
