The Kit Fox is a light Clan OmniMech with long-range combat as a primary focus, earning it the Inner Sphere codename of Uller, after the Norse god of archery.[2][5][6]

The Kit Fox was designed by Clan Cloud Cobra, and was first produced in 2890 with the aid of new resources coming from the Tanite Worlds. Rather than emphasize speed, the Kit Fox emphasizes armor and firepower, complementary to the role of the Fire Moth. Clan Jade Falcon Khan Bret Malthus took note of the new design after a string of Cloud Cobra victories, and issued a batchall to the Cobras, a challenge the Jade Falcons only very narrowly won. Clan Snow Raven also produces the Kit Fox, which they acquired by trade. All other Clans field the Kit Fox as isorla, except Clan Blood Spirit, who was gifted the Kit Fox by the generous (or Machiavellian) Ravens.[2][5][6]

Often fielded by Clan Jade Falcon, the Kit Fox has a surprising amount of firepower, with the 10 built-in double heat sinks sometimes barely able to fully cool the 'Mech down. However, the Kit Fox is somewhat slow for its weight class, only capable of a top speed of 97.2 km/h, provided by a lightweight 180-rated extralight fusion engine. Available tonnage is further increased by the use of a lightweight endo steel chassis, while four tons of ferro-fibrous armor provide the Kit Fox with ample protection.[2][5][6]

Because of Clan Jade Falcon's propensity to utilize this design, the Kit Fox has become part of a Clan Coyote adage:[7]

If you see a Falcon not in a Summoner, Hellbringer or Kit Fox, double your caution.

Weapons and Equipment[edit]

In its Primary configuration, the Kit Fox mounts an ER large laser and small pulse laser on the left arm as its primary source of firepower. These are supplemented by an LB-X AC/5 for tactical flexibility and a Streak SRM-4 rack for close range combat.[2][5][6]

Alternate Configurations[edit]

  • Alternate Configuration A 
    The A configuration of the Kit Fox uses a Gauss rifle as its primary long-range weapon, supported by two ER medium lasers provide medium and short-range firepower.[1] BV (1.0) = 1,218[3], BV (2.0) = 1,310[2][8] or 1,313[1]
  • Alternate Configuration B 
    The B configuration of the Kit Fox boasts a rapid-fire UAC/10 as its primary weapon, startling considering the 'Mech's tonnage. An ER medium laser, ER small laser, and an SRM-6 rack allow the Kit Fox B to finish off anything that manages to close ranges[1]. BV (1.0) = 1,016[3], BV (2.0) = 1,088,[2] 1,087[9] or 1,090[1]
  • Alternate Configuration C 
    An attempt to employ the Kit Fox in a scouting role, the C configuration has but one ER large laser for long-range combat. Instead, the Kit Fox C mounts numerous light weapons, equipped with a small pulse laser and dual machine guns; two A-Pods provide excellent protection against infantry. While the Kit Fox C still had a somewhat slow speed, it was far more durable than other scout 'Mechs, and carried an array of three anti-missile systems and an ECM suite to further increase its survivability. An active probe allows for detection of hidden units while scouting and a TAG designator is carried to call down artillery.[1] BV (1.0) = 1,195[3], BV (2.0) = 1,150,[2] 1,147[10] or 1,151[1]
  • Alternate Configuration D 
    The Kit Fox D is configured for indirect fire support, mounting dual LRM-15 racks as well as an LRM-5. A Narc missile beacon is also carried, which may be exploited by the Kit Fox D itself as the targeting systems of Clan LRMs lack a minimum range; this literally allows the Kit Fox D to run up to an enemy and mark them for increased accuracy and then fall back, firing the entire time.[1] BV (1.0) = 1,070[3], BV (2.0) = 1,142[2][11] or 1,145[1]
  • Alternate Configuration E 
    The Kit Fox E sports the new Advanced Tactical Missile system, mounting an ATM-3 rack which can fire ammunition specifically designed for maximum effectiveness at a certain range. Six added jump jets, allowing for a jump capacity of 180 meters, provide the Kit Fox E with additional mobility and allow it to better exploit the ATM systems, and an ER PPC provides the high firepower common to the 'Mech; an ER small laser provides point defense.[1] BV (1.0) = 1,520[3][12], BV (2.0) = 1,418[2] or 1,415[1][13]
  • Alternate Configuration F 
    The F configuration of the Kit Fox is armed with a powerful Hyper-Assault Gauss Rifle 20, which is capable of delivering large amounts of damage, especially for such a small 'Mech. This is backed up by two medium pulse lasers for close combat.[1] BV (2.0) = 1,219[1][2][14]
  • Alternate Configuration G 
    The G configuration is armed with a pair of LRM-10 missile launchers. An ER large laser and ER medium laser mounted in the right arm provide additional firepower, while the left arm carries an ECM suite to disrupt enemy electronics. BV (2.0) = 1,368[15]
  • Alternate Configuration J 
    The J configuration has two ER medium lasers in the left arm, while the right arm carries a UAC/5 and a Streak SRM-2. The autocannon has two tons of ammunition and the Streak has a single ton of ammunition. Two jump jets are in each leg and a single jump jet is installed in each side torso to provide a jump radius of 180 meters. BV (2.0) = 1,178[18]
  • Alternate Configuration K 
    A heavy striker configuration, the K carries an LB 10-X in the right arm and an improved heavy large laser in the left arm. Two tons of LB-X ammunition is carried as well. BV (2.0) = 1,109[18]
  • Alternate Configuration R 
    This configuration is equipped with a RAC/5 in the left arm, with two tons of ammo in the left torso, and Streak SRM-6 in the right arm. A single ton of Streak ammo resides in the right torso. BV (2.0) = 1,232[19]
  • Alternate Configuration U 
    Used in Jihad-era underwater conflicts, this configuration carries a quartet of LRT-5 launchers in each arm and a single ER medium laser in the torso. Six experimental UMUs allow the Kit Fox U to match its cruising ground speed underwater. BV (2.0) = 1,434[21]
  • Alternate Configuration V 
    This configuration provides fast artillery support to Clan forces via an Arrow IV system, fed with three tons of ammunition. For close in defense the left arm has two ER small lasers. BV (2.0) = 974[18]
  • Alternate Configuration W 
    Intended for medium to close range combat, the W configuration carries a simple yet effective arsenal. Its primary weapons are a pair of large pulse lasers which are backed up by two medium pulse lasers for close range combat.[1] BV (2.0) = 1,431[1][2][22]

These variants were introduced in various apocryphal sources, and thus far have not appeared in any canonical media.

From MechWarrior Online:

  • KFX-P
    This PGI-created variant mounts a UAC/5 as its primary weapon in the left arm, backed up by an SRM-4 in each arm and three ER medium lasers. For anti-infantry work and increased close-range firepower, the 'Mech mounts a machine gun in each torso. A laser AMS in the right arm supplements the defensive capabilities of this configuration. All ammo-dependent weapons have one ton of ammunition allocated.[2]
