The far-infrared and submillimeter regimes harbor significant numbers of strong lines useful as diagnostics of processes in the interstellar medium, regions of intense star formation, and AGN activity. Covering a decade or more in wavelength, many of them are emitted or redshifted to wavelengths where they are obscured by atmospheric absorption, and so airborne and space-based instruments must be used. Capable, sensitive detector arrays are needed for this; we have been developing such arrays based on multiplexed superconducting bolometers. At the present level of maturity, we have fielded a submillimeter spectrometer containing around ten detectors of the requisite sensitivity. In the coming months, new instruments will demonstrate up to of order 100 bolometers (e.g., 8× 16). We are working to implement over a thousand pixels in a single detector package. One application for such large arrays is the 100 μ m-655 μ m spectrometer SAFIRE on SOFIA. Future directions will be for space-based observatories such as SAFIR.
