We have implemented and tested a suite of grisms that will enable a moderate-resolution mid-infrared spectroscopic mode in FORCAST, the facility mid-infrared camera on SOFIA. We have tested the hardware for the spectral modes extensively in the laboratory with grisms installed in the FORCAST filter wheels. The grisms perform as designed, consistently producing spectra at resolving powers in the 200-1200 range at wavelengths from 5 to 38 microns. In anticipation of offering this capability as a SOFIA general observer mode, we are developing software for reduction and analysis of FORCAST spectra, a spectrophotometric calibration plan, and detailed plans for in-flight tests prior to commissioning the modes. We present a brief summary of the FORCAST grism spectroscopic system and a status report.
