The fully relativistic multiconfiguration Dirac--Hartree--Fock method is usedto compute excitation energies and lifetimes for the 143 lowest states of the$3s^23p^3$, $3s3p^4$, $3s^23p^23d$, $3s3p^33d$, $3p^5$, $3s^23p3d^2$configurations in P-like ions from Cr X to Zn XVI. Multipole (E1, M1, E2, M2)transition rates, line strengths, oscillator strengths, and branching fractionsamong these states are also given. Valence-valence and core-valence electroncorrelation effects are systematically accounted for using large basis functionexpansions. Computed excitation energies are compared with the NIST ASD andCHIANTI compiled values and previous calculations. The mean average absolutedifference, removing obvious outliers, between computed and observed energiesfor the 41 lowest identified levels in Fe XII is only 0.057 \%, implying thatthe computed energies are accurate enough to aid identification of new emissionlines from the sun and other astrophysical sources. The amount of energy andtransition data of high accuracy is significantly increased for several P-likeions of astrophysics interest, where experimental data are still very scarce.
