  Recent advances in theoretical atomic physics have enabled large-scale
calculation of atomic parameters for a variety of atomic processes with high
degree of precision. The development and application of these methods is the
aim of the Iron Project. At present the primary focus is on collisional
processes for all ions of iron, Fe I- FeXXVI, and other iron-peak elements; new
work on radiative processes has also been initiated. Varied applications of the
Iron Project work to X-ray astronomy are discussed, and more general
applications to other spectral ranges are pointed out. The IP work forms the
basis for more specialized projects such as the RMaX Project, and the work on
photoionization/recombination, and aims to provide a comprehensive and
self-consistent set of accurate collsional and radiative cross sections, and
transition probabilities, within the framework of relativistic close coupling
formulation using the Breit-Pauli R-Matrix method. An illustrative example is
presented of how the IP data may be utilised in the formation of X-ray spectra
of the K$\alpha$ complex at 6.7 keV from He-like Fe XXV.
