The 'TSS Adventurous was the first starship of the Adventurous class. It was commissioned in 2140, and was the class' flagship, as well as its namesake. The Adventurous commanding officer was Captain Oria Natsuno.
The TSS Equality was the third vessel of the Adventurous class. Commissioned in 2143, the Equality was attacked and boarded by pirates intent on stealing the new technologies on board the vessel. Her commanding officer, Captain Toral Maisha, was forced to initiate the Equalitys self-destruct sequence, destroying the vessel. However, the entire crew escaped unharmed. The pirates, however, weren't so lucky.
