The VLA-COSMOS large project is described and its scientific objective isdiscussed. We present a catalog of ~ 3,600 radio sources found in the 2deg^2COSMOS field at 1.4 GHz. The observations in the VLA A and C configurationresulted in a resolution of 1.5''x1.4'' and a mean rms noise of ~ 10.5(15)uJy/beam in the central 1(2)deg^2. 80 radio sources are clearly extendedconsisting of multiple components, and most of them appear to be double-lobedradio galaxies. The astrometry of the catalog has been thoroughly tested andthe uncertainty in the relative and absolute astrometry are 130mas and <55mas,respectively.
