We present infrared observations of the ultracompact H II region W3(OH) made by the FORCAST instrument aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA) and by the Spitzer/Infrared Array Camera. We contribute new wavelength data to the spectral energy distribution (SED), which constrains the optical depth, grain size distribution, and temperature gradient of the dusty shell surrounding the H II region. We model the dust component as a spherical shell containing an inner cavity with radius ~600 AU, irradiated by a central star of type 09 and temperature ~31,000 K. The total luminosity of this system is 7.1 x 10 super(4) L sub(middot in circle). An observed excess of 2.2-4.5 mum emission in the SED can be explained by our viewing a cavity opening or dumpiness in the shell structure whereby radiation from the warm interior of the shell can escape. We claim to detect the nearby water maser source W3 (H sub(2)O) at 31.4 and 37.1 mum using beam deconvolution of the FORCAST images.
