Among the smallest and lightest WarShips of the Clan Invasion Era, the Free Worlds League's Zechetinu-class corvette was designed to operate as either an independent convoy-raider, picket ship, or as an escort vessel.[6]

The "Zec" as her crews dubbed the vessel is capable of accelerating up to 2.5 g for sustained periods and up to 4 g in short bursts, making it among the fastest and most maneuverable WarShips in its weight class. This speed came at a price, with a relatively light ninety tons of Lamellor Ferro-Carbide armor in comparison to its weapons array and exceedingly cramped crew quarters made even tighter with the inclusion of a Lithium-Fusion Battery System. With one tiny and constantly in demand Grav Deck the only dedicated recreation facility aboard, each Zechetinu rarely spent more than a month away from port to avoid negative effects on the well-compensated crew.[4][6]

The first ship of the class exceeded all expectations during mock battle exercises and quickly led the Free Worlds League Military to authorize the construction of a further ten. Analysis of these exercises also led to the bulk being constructed as the newer Zechetinu II standard with a slightly modified weapons array.

More than half of the Zechetinus of the Free Worlds fleet was taken by Blakist defectors or sleeper agents.[7][8] All existing vessels of the class were destroyed in internecine combat by loyalist FWLM forces, in battle across the Inner Sphere against the schismatics in their Jihad, or lost to the wilds of the Periphery.[9]


The Block I Zechetinu featured a significant capital-grade weapons array supported by a large volume of anti-fighter systems. The fore and aft weapon bays both carry twin ER Large Lasers, four Small Lasers, an LB 10-X AC and Artemis IV FCS enhanced LRM-20 and SRM-6 launchers in support of a NAC/20 and twin NL35s. The forward-facing angle features twin ER Large Lasers, four Small Lasers, and an LB 10-X AC for anti-fighter duties while an NL35 and NL45 provide capital-grade firepower. Save for replacing both capital lasers with a single NL55, each rear angle features the same mix as the fore angles, while apart from dropping the capital lasers entirely, each broadside mounts the same weaponry as the fore and aft bays. One thousand and seventy-three double heat sinks give the class reasonable endurance.[4][6]


Beyond its ability to carry a single DropShip and six aerospace fighters, the Zechetinu featured thirteen thousand, eight hundred and seventy-six tons of cargo capacity divided between two separate bays.[4][6]

Block I
  • Bay 1: Aerospace Fighters (6), 2 doors
  • Bay 2: Cargo (6,938 tons), 5 doors
  • Bay 3: Cargo (6,938 tons), 5 doors
Block II
  • Bay 1: Aerospace Fighters (6), 2 doors
  • Bay 2: Cargo (6,188 tons), 5 doors
  • Bay 3: Cargo (6,188 tons), 5 doors


  • Zechetinu II 
    Starting with the FWLS Scorpion, all future Zechetinus were constructioned to the Block II standard and featured capital-grade missile systems in place of the naval-laser batteries of the Block I ships, with two White Shark tubes forward and aft, with a single Barracuda missile tube on each fore and aft angle. Carrying fifty missile reloads for each launcher type reduced the Zechetinu IIs cargo capacity down to twelve thousand, three hundred and seventy-six tons. BV (1.0)= 46,730[5] (34,119)[4]
