Leichang

The Leichang (Zhenian: 뇌창, literally 'Lightning Spear') is a to  developed by Zhenia's Li-Jien Dynamics, produced and deployed primarily for the Republic of Zhenia Army, but eventually the Air Force and Navy. While it could in theory carry thermonuclear weapons, it normally carries one among the selection of non-nuclear warhead, with the primary intention of delivering precision strikes against high-value or strategic rear-area targets. Compared to its predecessor, it has shown significant improvements in accuracy and interceptor invasion, with an estimated of around 6 meters for the Leichang-2 variants. Developed to complement and replace the existing Cheonchang ballistic missiles that had seen service since the end of the November Revolution, the Leichang has been nicknamed the "nemesis of ballistic missile defense" due to its high accuracy, terminal evasive maneuvers, countermeasures and multiple guidance options.

Design characteristics
Although it has never been tested with a nuclear warhead, the Leichang is capable of being equipped with a 600 kg warhead that is equivalent to around 50 kilotons of, resulting in the missile being an ideal platform for the delivery of tactical nuclear weapons against rear targets. In most cases, the Leichang is equipped with other non-nuclear warheads, including high-explosive fragmentation, earth penetrator warheads nicknamed "bunker busters" by the Republic of Zhenia Army, cluster munitions aimed for large area destruction and thermobaric warheads. The warheads themselves can be adjusted according to the mission, at least among non-nuclear warheads, in a process that takes a matter of hours: missiles equipped with nuclear warheads, however, are inseparable from the missile until detonation or when the missile itself is dissected.

The missile itself, unlike its predecessors, follows a quasi-ballistic path that, which, involving a series of evasive maneuvers in the terminal phase, releasing decoys along the way and reaching its highest point far later in its flight path, in turn makes the interception of the missile much harder than its predecessors. With a more flat trajectory compared to other ballistic missiles, the missile does not leave the atmosphere altogether to minimize altitude for interception. Thrust vector control from the engines, as well as gas-dynamic and aerodynamic control surfaces allow for seamless control of the missile throughout its flight trajectory, including during its terminal phase, in which it dives towards the target in speeds up to Mach 10; prior to its terminal dive, it travels at a hypersonic speed of around Mach 6-7, with a maximum altitude of around 55 kilometers. The Leichang-1 missiles were built with a CEP of around 15-20 meters, while newer Leichang-2 missiles are estimated to have a CEP of around 5-6 meters depending on the type.

Throughout its course, the missile can be guided via multiple methods, but normally include an (INS) that is augmented with military-grade  provided by the Cheolian satellite network. With both INS and satellite guidance, the missile normally has a (CEP) of around 6-7 meters, while the CEP increases to around 40 meters when the missile is guided solely by INS. In practice, it could acquire its target via more conventional means, including data from aerial photos scanned into the computer, artillery observers and the like; for this purpose, the warhead also sports an electro-optical guidance module near its tip, which allows for self-homing capabilities and infrared-spectrum to compare its own data with provided targeting data. Its targeting information is also readily adjustable with feedback data from UAVs or nearby AEW&C aircraft.

Although there are also naval and air-launched variants of the missile, most Leichang missiles are launched from a eight-wheeled (TEL), which uses the eight-wheeled Jinmu Motors Tactical Vehicle-Heavy (JMTV-H) as its chassis. Each vehicle, carrying two of the missiles, is operated by a crew of three. Extensive automation has resulted in the vehicle being able to prepare to launch the missile in 4 minutes from high-readiness and around 14 minutes from being on the road. The cabin and launcher is armored to withstand direct hits from 7.62 mm rounds at 15 meters and 40 mm grenade shrapnel from roughly the same distance, while the cabin is also equipped with a CBRN filtration system in order to protect the crew in various battlefield circumstances.
