Commissioned in late 2660, the Wyvern was developed to fill the need for a dedicated city fighter. The Wyvern may fulfill its duties too well, for many pilots dislike the 'Mech's primary tasks of crowd control, garrison duty, security work, or urban defense. These are not flashy assignments, and so the Wyvern is not a flashy 'Mech.
         A few MechWarriors, however, enjoy piloting the 'Mech. In its element, the city, there are few 'Mechs of any size that it cannot handle, or at the very least harass. These veteran Wyvern pilots are among the proudest in the Star League military.

         As a city-fighter, the Wyvern does not need much ground speed. With a top speed of 65 kilometers per hour, the Wyvern cannot escape many of its foes by running away.
         It can, however, jump with considerable ease, powered by the jump jets in its rear torso and upper legs. This combination of average speed and average jumping ability make the Wyvern a sitting duck in the open field. When on attack, the 'Mech is normally used in heavy woods or mountainous terrain, where the ground effects tend to reduce the movement advantages of faster 'Mechs.
         The arm-mounted Nightwind Large Laser is the Wyvern's main weapon. Being an older design, the Nightwind's many system components have been refined through countless hours of battlefield tests. The system is extremely reliable, but most of the components are so bulky and heavy that the Nightwind is one of the largest military lasers ever produced. The Starflash Small Lasers cradled next to their bigger cousin where added later, after it was discovered that some of the Nightwind's power could be diverted with no loss of effectiveness.
         The Jackson Dart long range missile launcher has been a constant source of problems for Wyvern pilots. Because the weapon is located in front of the engine core, the heat of the engine often causes an automatic shutdown of the system. Normal coolant jackets have proven ineffective, and if a pilot attempts to override shutdown, the heat build-up can lead to an ammo explosion as the reloads are passed from the CASE in the left torso. The only proven solution is to keep the reactor's temperature as low as possible. If heat levels rise too high, the pilot can eject the loaded missiles and disable the autoloader, sealing the remaining missiles in the CASE.
         The Totschlagen-6 short-range missiles are much more reliable. Housed in the right torso, the launcher sits on top of the CASE. The entire reloading system is extremely compact, making reloading quick and efficient. If the system should jam, the reload tubes can usually be cleared by jumping the Wyvern up and down.
