This paper is a general update on the target fab specs for ignition targets for the National Ignition Facility. A general overview of the status of all the requirements is presented, with a historical summary plus recent results. Historical work will be related to recent systematization of the characterization as coordinated by Rich Stephens. New results to be presented include analysis of a polystrene-ablator target, analysis of Rayleigh-Taylor growth on beryllium targets driven at 250eV at various scales, simulations of the effect of fill tubes on the implosion, considerations of hohlraum and capsule size variations, and variations in DT gas density (i.e. capsule temperature).
