The Slayer is a Draconis Combine heavy aerospace fighter designed before the fall of the Star League, and is noted for its endurance and armor. A multirole fighter, the Slayer has the firepower to take on both other fighters and 'Mechs, with many pilots mistaking the compact design for a lighter craft, a mistake they rarely live to repeat. The Slayer also boasts a double capacity fuel tank, allowing it to loiter over the battlefield for extended periods of time.

Weapons and Equipment[edit]

While not the heaviest of armament, Slayers tend to carry enough weaponry to give any other fighter or 'Mech a bad day. With a Zeus 56 Mark IV AC/10 and a Diverse Optics Type 20 medium laser in the nose, backed up by four more medium lasers in the wings, the Slayer can lay down enough fire in one pass to destroy smaller craft. A single medium laser faces to the rear to discourage pursuit.


  • SL-15A 
    First in a series of unpopular uninspired modification kits developed by Wakazashi during the Third Succession War, the 15A trades the AC/10 for an LRM-15 and SRM-6 in the nose, supplied with two tons of reloads each.[5] BV (1.0) = 1,243;[6][7] BV (2.0) = 1,423
  • SL-15B 
    A different take on the 15A, this modification leaves the LRM-15 launcher in the nose but mounts the SRM-6 launcher aft.[5] BV (1.0) = 1,243[8][9]
  • SL-15C 
    The 15C merely reverses the 15B's weapon positioning, with the SRM-6 mounted in the nose and LRM-15 in the rear.[5] BV (1.0) = 1,243;[10][11] BV (2.0) = 1,379
  • SL-15R 
    Unwilling to mess with the popular design after the A/B/C variant debacle, this variant, introduced in 3044, simply replaces the older AC/10 for a more advanced Imperator Code Red LB 10-X AC and an extra ton of ammunition, a minor change that allowed it to be quickly applied to the production line and as a simple field refit for existing fighters.[12][5] BV (1.0) = 1,353;[13][14] BV (2.0) = 1,384

Custom / Experimental Variants[edit]

  • Slayer Eric 
    This Slayer variant replaces the autocannon with a pair of ER PPCs, carries 15 tons of heavy ferro-aluminum armor and 20 double heat sinks. For close combat, the Slayer Eric carries five medium lasers, two in each wing and one covering the aft arc. BV (1.0) = 1,830[17]


  • In German products, the unit's proper name was altered to Killer. The model code was accordingly changed to KL-15.
