Microwave Kinetic Inductance Detector (MKID) arrays, recently demonstrated at the Palomar 200 inch telescope, are a new superconducting detector technology that has great potential for astrophysics. We propose a new type of instrument, a Superconducting Multi-Object Spectrograph (SuperMOS), that uses MKIDs in conjunction with a focal plane mask. We present the design and science goals of a SuperMOS designed for LSST follow-up named Giga-z. Housing a 100,000 pixel MKID array with energy resolution R=50{100 and a 0.35-1.35 μm bandwidth, it will be capable of measuring 2 billion spectra and determining redshifts over 20,000 square degrees in 3 years down to mi ≈ 24.5 on a dedicated 4-meter telescope. Compared to LSST alone, Giga-z should improve the redshift precision by a factor of three with a much lower catastrophic failure rate.
