We present an overview of the ongoing progress towards flight readiness of the SIM project. We summarize the engineering milestones that have been completed in the last two years, namely: the Brass-Board Internal and External Metrology Beam Launchers, the Brass-Board Metrology Source, and the Instrument Communication Hardware/Software Architecture Demonstration. We also show other progress such as: the life test of the bass-screw and PZT actuators, building the Metrology Fiducials and the Single Strut Test Article. We status the ongoing work on the Brass-Board Fast Steering Mirror and the Brass-Board Astrometric Beam Combiner. We end with a proposed path towards finishing the Brass-Board suite.
