SHIP is a new general purpose fixed target facility, whose Technical Proposal has been submitted to the CERN SPS Committee in 2015. The 400 GeV proton beam extracted from the SPS will be dumped on a heavy target with the aim of integrating 2 times 10 20 proton-target collisions in 5 years. A dedicated detector, based on a long vacuum tank followed by a spectrometer and particle identification detectors, will allow probing a variety of models with light long-lived exotic particles with masses below O(10) GeV/c^2. The main focus will be the physics of the so-called Hidden Portals, i.e. search for Dark Photons, Light scalars and pseudo-scalars, and Heavy Neutrinos. The sensitivity to Heavy Neutrinos will allow for the first time to probe, in the mass range between the kaon and the charm meson mass, a coupling range for which baryogenesis and active neutrino masses could be explained at once. Direct detection of other light and long-lived exotic particles could also be performed in an unexplored parameter range. Another dedicated detector, based on technologies developed for the OPERA experiment at LNGS , will allow the study of SM neutrino cross-sections and angular distributions. \nu_\tau deep inelastic scattering cross sections will be measured with 1000 times better statistics than currently available, allowing to extract the F_4 and F_5 structure functions, never measured so far. Moreover, \nu_\tau’s will be distinguished from \bar{\nu}_\tau’s, thus providing the first observation of the \bar{\nu}_\tau.
