This document describes the technical layout and the expected performance of the Straw Tube Tracker (STT), the main tracking detector of the $\overline{P}$ ANDA target spectrometer. The STT encloses a Micro-Vertex-Detector (MVD) for the inner tracking and is followed in beam direction by a set of GEM stations. The tasks of the STT are the measurement of the particle momentum from the reconstructed trajectory and the measurement of the specific energy loss for a particle identification. Dedicated simulations with full analysis studies of certain proton-antiproton reactions, identified as being benchmark tests for the whole $\overline{P}$ ANDA scientific program, have been performed to test the STT layout and performance. The results are presented, and the time lines to construct the STT are described.
