Precision pulsar timing at the level of tens to hundreds of nanosecondsallows detection of nanohertz gravitational waves (GWs) from supermassivebinary black holes (SMBBHs) at the cores of merging galaxies and, potentially,from exotic sources such as cosmic strings. The same timing data used for GWastronomy also yield precision masses of neutron stars orbiting other compactobjects, constraints on the equation of state of nuclear matter, and precisiontests of General Relativity, the Strong Equivalence Principle, and alternativetheories of gravity. Timing can also lead to stringent constraints on thephoton mass and on changes in fundamental constants and could reveal low massobjects (rogue planets, dark matter clumps) that traverse pulsar lines ofsight. Data sets also allow modeling of the density, magnetic field, andturbulence in the interstellar plasma. Roughly 100 millisecond pulsars (MSPs)are currently being timed at $\sim$GHz frequencies using the largest radiotelescopes in the world. These data sets currently represent ~1000 pulsar-yearsand will increase dramatically over the next decade. These topics are presentedas a program of key science with flowdown technical requirements for achievingthe science.
