The Valkyrie was originally planned for use by the SLDF but production of the 'Mech did not start until after the fall of the Star League. Because of this odd twist of fate the only nation that possesses a large number of Valkyries is the Federated Suns. During the Succession Wars the Valkyrie became the standard light 'Mech of the AFFS in the lace of 'Mechs like the Wasp and Stinger. While not as fast as either design the Valkyrie has an almost comparable ground speed, heavier armor and a jumping distance just 30 meters shorter of either the Wasp or Stinger.
The Valkyrie has an armament that consists of a Devastator Series-07 LRM 10 launcher and a Sutel IX Medium Laser. This mix of long and short-range weapons allows the Valkyrie to soften up other 'Mechs from long range then move in for a kill. Also when working as part of a scout lance the Valkyrie can operate in a fire support role.

- VLK-QD1 - The QD1 is another major overhaul of the Valkyrie. It is powered by an extralight engine and built using Endo Steel construction. The Valkyrie carries an Extended Range Medium Laser and a LRM 15. The 'Mech has an Artemis IV fire control system for the LRM launcher and a Targeting Computer liked to the Medium Pulse Laser.
