SIDRAT
Type:	Space-time vessel
Place of origin:	War Lords (using Time Lord technology)
Appearances:	DW: The War Games

A SIDRAT (pronouced "sigh-drat", not "sid-rat") was a type of space-time vehicle used by the War Lords and built with the assistance of the War Chief, a renegade Time Lord.

While similar to TARDISes, SIDRATs were somewhat less developed time/spaces travelling machines. It has also been stated that they are the most basic kind of TARDIS, possibly early TARDIS prototypes. The Second Doctor found that it wasn't "difficult" to figure out the operation of the machines. Also like TARDISes, they were larger on the inside than on the outside. According to Jamie they were green in color.

Another source says they are powered by energy crystals, probably Zeiton-7. The Time Lords discounted them as viable space-time transports due to their short range and power costs. From the outside they resembled featureless rectangle boxes, similar in appearance to a form sometimes used by TARDISes while on Gallifrey (possibly a "default" exterior for TARDISes). The War Lords employed them both to abduct Human soldiers for the war games, and also to travel back and forth from the game area to their base. (DW: The War Games)

According to one source, the name may have been an acronym for "Space and Inter-Dimensional Robot All-purpose Transporter". (DWN: Doctor Who and the War Games)
