The Piranha was developed by Clan Diamond Shark shortly before the Battle of Tukayyid to combat Inner Sphere conventional infantry and light vehicles. The sheer speed that the BattleMech is capable of has also made it something of a scout, though it lacks sophisticated electronic equipment. The Piranha is protected mostly by its speed, though it does mount four tons of armor. In the late 3060s, Clan Ice Hellion bid for and won the right to produce the 'Mech themselves. The Hellions have created new variants on the Piranha, though they maintain the original design philosophy.[1][5][6]

Weapons and Equipment[edit]

The Piranha's main threat is its twelve Series XII Rotary Machine Guns. These are a serious threat to any foe on such a speedy 'Mech, especially if a Star of Piranhas operate in a pack, and such a large array allows a Piranha to chew through an opponent's rear armor almost instantly. They are most deadly, however, to unarmored infantry, capable of wiping out an entire company in seconds. For work against hardened targets, the Piranha mounts a pair of Mk. 3 ER Medium Lasers and a single Series 1 ER Small Laser. Since the design only uses ten single heat sinks, the MechWarrior must still manage heat levels. The ammunition dependency of the Machine Guns ensure that Piranhas must stay close to supply lines, so most have been relegated to solahma or garrison roles.[1][6]


  • Piranha 4 
    This version uses two Machine Gun Arrays to make it more effective in combat. One array mounts Light Machine Guns, while the other mounts standard Machine Guns. The ER Medium Lasers are tied into a Targeting Computer as well.[11] BV (2.0) = 1063[12]
