  Gravitational solutions involving shockwaves have attracted significant
recent interest in the context of black holes and quantum chaos. Certain
classes of supersymmetric two-charge black hole microstates are described by
supergravity solutions containing shockwaves, that are horizonless and smooth
away from the shockwave. These configurations have been used to describe how
black hole microstates absorb and scramble perturbations. In this paper we
construct the first family of asymptotically flat supersymmetric three-charge
microstate solutions that contain shockwaves. We identify a family of
holographically dual states of the D1-D5 CFT and show that these pass a set of
tests, including a precision holographic test. We find precise agreement
between gravity and CFT. Our results may prove useful for constructing more
general families of black hole microstate solutions.
