The SS Shiku Maru was a 24th century Federation starship. This vessel was commanded by Captain A. Silvestri. On stardate 25058.4, this starship encountered a Tamarian deep space cruiser. Though the encounter was peaceful, the crew of the Shiku Maru were unable to establish communication with the Tamarians due to language difficulties. The ship's captain described the language of the Tamarians as incomprehensible. (TNG: "Darmok")

The Shiku Maru's registry was seen on screen in "Darmok" on a display graphic. It appeared to be either NDT-30064 or NDT-38864, though the second and third number were somewhat illegible.
