  We present the Hubble Deep UV Legacy Survey (HDUV), a 132 orbit imaging
program with the WFC3/UVIS camera onboard the Hubble Space Telescope (HST). The
HDUV extends and builds on the few previous UV imaging surveys in the two
GOODS/CANDELS-Deep fields to provide deep images over a total area of ~100
arcmin2 in the two filters F275W and F336W. Our release also includes all the
F275W imaging data taken by the CANDELS survey, which were aligned using a
novel approach and combined with the HDUV survey data. By reaching depths of
27.5-28.0 mag (5sigma, in 0.4" apertures), these are the deepest
high-resolution UV data over such a large area taken to date. Such unique UV
imaging enables a wide range of science by the community. Among the main goals
of the HDUV survey are: (1) provide a complete sample of faint star-forming
galaxies at z~1-3, (2) constrain the ionizing photon escape fraction from
galaxies at z~2-3, and (3) track the build-up of bulges and the disappearance
of clumpy disk galaxies through reliable internal stellar population properties
at sub-kpc resolution out to z~3. The addition of the HDUV data further
enhances the legacy value of the two GOODS/CANDELS-Deep fields, which now
include deep 11-band HST imaging as well as very deep ancillary data from X-ray
to radio, enabling unique multi-wavelength studies. Here, we provide an
overview of the survey design, describe the data reduction, and highlight a few
basic analyses on the images which are released to the community as high level
science products via the Mikulski Archive for Space Telescopes (MAST).
