A light, rugged, and dependable design, the Wolfhound made its first appearance in 3028. Following the success of the Hatchetmandesigned in partnership with the Federated Suns, Archon Katrina Steiner ordered TharHes Industries to produce a BattleMech to address a persistent problem of the Lyran Commonwealth Armed Forces: hunting down and destroying the Panther and Jenner, swift light-weight 'Mechs of the Draconis Combine which had embarrassed the LCAF one too many times. The final design was a light 'Mech with an all-energy weapons payload effective at a variety of combat ranges, the maximum amount of armor for a 'Mech of its weight class, and the use of mostly standard components to keep costs down.
Due to their fierce loyalty to House Steiner, the Kell Hounds were the first unit chosen to field test the Wolfhound in combat, followed shortly thereafter by Wolf's Dragoons. The design received its baptism of fire during the Fourth Succession War where it exceeded all expectations and performed brilliantly. This was especially true when the Wolfhound faced its intended targets, hitting the Jenner beyond its ability to return fire while closing the distance on the Panther to get within the minimum range of its primary weapon. With the successful end of the war the Federated Commonwealth ordered larger numbers of Wolfhounds to outfit its military and the design was used again during the War of 3039.Wolfhounds suffered far fewer casualties than other 'Mechs during that conflict and a mere handful fell into the hands of the Combine. While impressed with the 'Mech the Kuritans were too prideful to copy it themselves, instead using captured examples to help develop the Wolf Trap to specifically counter the 'Mech.
Eventually Arc-Royal MechWorks was brought in to produce Wolfhounds under license from TharHes, and the recovery of Lostech thanks to the Helm Memory Core allowed for a more advanced variant to be produced to combat the Clan Invasion. Unfortunately the necessary retooling of TharHes' factories to produce the WLF-2 model, introduced in 3052, took too long before ComStar brought an end to the invasion with the Battle of Tukayyid. These newer Wolfhounds continued to be produced for both FedCom member states, although following the formal creation of the Lyran Alliance the TharHes factories began producing the newer WLF-3S model. This new variant was shipped only to units loyal to the Lyran state, and thus fought on the side of Katherine Steiner-Davion during the FedCom Civil War. During the Jihad the Word of Blake launched a devastating assault on Tharkad, effectively shutting down TharHes' Wolfhound factory line; in response Arc-Royal increased production and introduced the WLF-4 model to replace the losses suffered by allied forces fighting the Blakists.
