Introduced in the late Jihad in 3078, the Sphinx was designed by Clan Nova Cat as a heavier companion to the Black Hawk OmniMech. The design was originally intended to be an OmniMech, but was changed due to the need to field 'Mechs more quickly to combat the Blakists.[1]

The Sphinx is built around an array of multiple lasers, allowing it to put out a massive amount of firepower at moderate ranges. It also maintains a similar movement profile to the Black Hawk although it lacks the jump jets of the lighter design. Its heavier frame also supports 13.5 tons of standard Clan armor, making it more durable than the smaller Black Hawk. Helping to cope with the heavy heat burden that its weapons mix can generate, it is fitted with 23 Double Heat Sinks.[1]

The 'Mech's appearance was noted as being a bit unpolished due to it being rushed into production. Its rough appearance gives it a look reminiscent of the old Highlander Assault 'Mech.[1]

Weapons and Equipment[edit]

The Mech's principal armament is a pair of arm-mounted Series 6b Extended Range Large Lasers. These weapons give the 'Mech its ranged combat ability. For intermediate ranges, the 'Mech can turn to its ten Series 2f Extended Range Medium Lasers, all of which are mounted in its side torsos.[1]


  • Sphinx
    The second variant appeared in 3080[4], just prior to the end of the Jihad. This variant was produced by Clan Nova Cat in preparation for the last thrust against the Blakists. The design drops all its ER Mediums Lasers and a single Double Heat Sink for the following modifications: In place of the ER Medium Lasers, a series of 10 ER Small Lasers are split up between the side torsos. Also, both ER Large Lasers are moved to the Center Torso, and MASC has been added. To help with more precise strikes, a Targeting Computer is added[1]. BV (2.0) = 2,753[5][4]
  • Sphinx
    This Dark Age era variant developed in 3091[6] carries is the reverse of the Sphinx 2. It removes the ER Large Lasers of the original, but retains the ER Medium Lasers. It adds a Targeting Computer and MASC to quickly enter close range combat. An ECM Suite disrupts enemy communications and targeting systems. BV (2.0) = 3,396[7][6]
  • Sphinx
    Another Dark Age era variant introduced also in 3091[8], this model carries eight Heavy Small Lasers and two Large Pulse Lasers. Twenty-four double heat sinks keep the heat under control. BV (2.0) = 1,952[9][8] NOTE: This model is identical to the Dark Age NC101-54B variant listed below.

Dark Age Dossier Variants[edit]

  • SF156-06A 
    A Sea Fox modification, this variant removes the Targeting Computer and MASC systems. It also uses ferro-fibrous armor to free up additional payload space for the inclusion of two additional ER Large Lasers. This version is known for its common overheating.

  • Originally, the dossiers for the Sphinx indicated the 'Mech was fitted out with 10 Clan ER medium lasers, MASC (108 km/h) and a targeting computer. Technical Readout: 3085 showcased the first canon stats for the 'Mech for the Jihad era. This would supersede previous published variants.
