These ships were sent into enemy territory before an attack fleet to spy on the enemy and were often equipped with cloaking shadows to guide in the invasion force. A yorik-strohna was made from yorik coral and covered with layers of rock, which extended to a depth of fifty meters everywhere except their main cooling vane, which was disguised as a crevasse in the surface.
Individual yorik-stronha varied, as, in spite of their outward appearance, they had been grown organically, like all Yuuzhan Vong vessels. They were designed to be around 228 meters long, with a crew of twelve and provision for a dozen passengers, plus a cargo capacity of 142 tons, and enough supplies for two months.
Armament included ten yaret-kors and a dovin basal tractor beam, but, while reasonably maneuverable, they were only moderately fast at sublight speeds and their darkspace drive was the equivalent of just a Class 3 hyperdrive, as this involved a far slower reversion to realspace, which was far harder for enemy sensors to detect.
