The Hornet debuted in 2760 as an urban recon 'Mech, but lack of interest forced the design to be shelved two years later. In the meantime though, the SLDF had procured the HNT–151 variant in some numbers.[5] In 2990, Kallon Industries rediscovered the blueprints and resumed production. The upgraded HNT-171 started production in 3051. The production line was destroyed by the Capellans in 3069. The 'Mech is designed around the concept of being able to swiftly move through an urban environment with relatively heavy armor. Overall, because of its eclectic mix of weapons and relatively slow speed, the Hornet is only somewhat effective when inside of a city. When caught outside an urban environment the 'Mech is hard pressed to defend itself.[1][6]

Weapons and Equipment[edit]

Kallon had a hard time selling the Hornet to the Armed Forces of the Federated Suns, so most of these 'Mechs initially went to the mercenary market. A major user of the initial runs was Wolf's Dragoons, who demonstrated its effectiveness on Misery. This caused the Federated Suns to take renewed interest in this 'Mech.[6]

Since then, the Hornet has been deployed by March Militias as a replacement for Wasps and Stingers, as well as by the Ceti Hussars and Deneb Light Cavalry. It is also still popular among mercenaries.[1][6]


The Hornet carries as its primary long-range weapon a Holly LRM-5 launcher. This allows the Hornet to strike at an enemy at a distance of over six hundred meters. In an urban environment the LRM launcher becomes more of a liability than an asset. As a secondary weapon the Hornet carries a Martell Medium Laser, and finally the 'Mech is armed with a MainFire Point Defense Anti-Missile System to defend against missile attacks.[1]


  • HNT-151 
    The version of the Hornet that debuted in 2990, the 151, has standard armor and a standard internal structure. It also lacks the advanced Anti-Missile System, CASE, and a ton of LRM ammunition, though the jumping capacity is one hundred fifty meters and the weapons also include a small laser.[6] BV (1.0) = 429, BV (2.0) = 488[7]
  • HNT-152 
    A fairly common field modification of the 151, the 152 replaces the LRM with a Holly SRM-4. BV (2.0) = 475[8]
  • HNT-182 
    A field refit of the 181 Hornet, this model replaces the small lasers with standard Medium Lasers. BV (2.0) = 505[10]

Design Quirks[edit]

The Hornet has the following Design Quirks:[11]

The HNT-181 Hornet variant is subject to the following Design Quirks:[2]


  • In The Spider and the Wolf, when a MechWarrior reports "Hornet, ready" the associated BattleMech is drawn like the Legios fighter/Alpha Veritech from the anime Genesis Climber Mospeada, also used as part of the Robotech series. This would have made this 'Mech one of the Unseen had the image not later been identified as an error and declared noncanonical. All subsequent depictions of the Hornet have had its present shape. Fan speculation suggests from the context in the comic that the 'Mech depicted may have been a modified Stinger instead; and the MechWarrior in question may have nominally been assigned a Hornet that was out of commission at the time, or may have stated his radio call sign instead of his exact 'Mech. Later publications indeed list this particular MechWarrior as piloting a Stinger, not a Hornet.
  • In German products the unit's proper name was altered to Hummel, which means Bumblebee. The model code was accordingly changed to HML-151.
