HYDRA was an early capability-based, object-oriented, microkernel designed to support a wide range of possible operating systems to run on top of it.[1] HYDRA was created as part of the C.mmp project at Carnegie-Mellon University in 1971.[2]

HYDRA was designed to be modular and secure, and intended to be flexible enough for easy experimentation.[3] The system was implemented in the programming language BLISS.[4]
