Today Iran test-fired its longest-range solid-propellant missile, Sejil-2. The new missile has a 2000-2500 km range. Tehran had test-fired shorter-range Sejil-1 missile last November.
Solid-propellant rockets can be fueled in advance and moved into silos, making them more potent than liquid-propellant rockets which need to be fueled and fired quickly.
