A topic of significant current interest is the star formation rate (SFR) in the z=3 Lyman Break Galaxy (LBG) population and their relation to high redshift luminous infrared/submm galaxies and the Cosmic Infrared Background (CIB). Until the launch of SIRTF, star formation in LBGs was inferred from their rest-frame UV and optical data alone. Unfortunately, unknown extinction and star formation histories greatly hinder any SFR determination. With 5σ sensitivities at 70μ m, 160μ m, and 20cm, of 2.75 mJy, 17.5 mJy, and 15μ Jy respectively, the SIRTF Wide-area InfraRed Extragalactic Survey (SWIRE) may detect the brightest end of the LBG luminosity function. The detection of the radio emission and reprocessed UV in the mid-far IR will allow a more direct determination of LBG SFRs, extinction laws, and their contribution to the CIB. The candidates for SWIRE detection and extinction analysis techniques will be reviewed. This work is supported by NASA-SIRTF Legacy Program funding to UCSD.
