The UNN Wu Tsao is a frigate of the United Nations Navy. It was one of the better armed frigates in the UNN.
After the Ganymede incident, which Admiral Augusto Nguyễn believed Mars was behind, he built a fleet of ships, including the Wu Tsao, to respond. Chrisjen Avasarala was successful in subverting the ship by having the ship's captain promoted to the head of the construction oversight committee. This required the ship to return from port so that the entire command crew would be present when they pinned a ribbon on him.
"Wu Tsao" or "Wu Zao" was a nineteenth-century Chinese poet
