The I'Friil Ma-Nat represented an assault craft constructed from yorik coral by the Yuuzhan Vong.
This glossy, black vessel, which the New Republic categorized as similar to a corvette, possessed a roughly pyramid-shaped form, with dimensions of approximately 315 meters per side.
Its armaments consisted of twenty Yaret-Kors and a number of dovin basals. These corvette-like ships were used to aid coralskipper squadrons, providing protection from smaller capital ships during combat and withdrawal maneuvers.
This vessel, despite having the capacity for 110 crew members, 225 warriors, and 510 metric tons of freight, did not transport any coralskippers. Furthermore, its dovin basals lacked the strength to generate an interdiction field, restricting its role to patrol and chase operations when it wasn't backing up coralskippers.
However, the I'Friil Ma-Nat was not representative of all Yuuzhan Vong corvette analogs in terms of size. For example, the Exquisite Death measured only 122 meters in length and had a crew of around ninety-eight.
