Rates and line strengths are calculated for the 2s{sup 2}2p{sup 5}3l3l{sup '}-2s{sup 2}2p{sup 6}3l{sup ''} and 2s2p{sup 6}3l3l{sup '}-2s{sup 2}2p{sup 6}3l{sup ''} electric-dipole (E1) transitions in Na-like ions with nuclear charges ranging from Z=14 to 100. Relativistic many-body perturbation theory (RMBPT), including the Breit interaction, is used to evaluate retarded E1 matrix elements in length and velocity forms. The calculations start from a 1s{sup 2}2s{sup 2}2p{sup 6} Dirac-Fock potential. First-order RMBPT is used to obtain intermediate coupling coefficients and second-order RMBPT is used to calculate transition matrix elements. A detailed discussion of the various contributions to dipole matrix elements is given for sodiumlike copper (Z=29). Transition energies used in the calculation of transition rates are from second-order RMBPT. Trends of transition rates as functions of Z are shown graphically for selected transitions.
