Subsea hard rock is the stratum that ocean drilling will inevitably encounter to achieve the goal of “Moho Drilling”. During the many ocean drilling expeditions， hard rock were encountered subsea many times. Not only have core samples been collected， but also many problems have been discovered in the drilling operation. This article collects data on subsea hard rock drilling expeditions in ocean drilling carried out in recent years， including 309， 312， 335， 360 and 384. A brief review of the expeditions is made with focuses on the challenges encountered in the current subsea hard rock drilling in terms of drill bits， wellbore stabilization and coring tools， as well as the solutions； and a prediction is also made of the development of subsea hard rock drilling in the future.
