Mark McKinnon (NRAO) ngVLA Programmatic and Technical Update With the guidance of Science and Technical Advisory Councils and Science Working Groups, the NRAO has sponsored a series of science and technical community meetings to consider the science mission and design of a next-generation Very Large Array (ngVLA). The basic ngVLA design emerging from these discussions is an interferometric array with approximately ten times the sensitivity and ten times higher spatial resolution than the VLA and ALMA radio telescopes, optimized for operation in the wavelength range 0.3cm to 3cm. The ngVLA will open a new window on the Universe through ultra-sensitive imaging of thermal line and continuum emission down to sub-milliarcsecond resolution, as well as unprecedented broadband continuum polarimetric imaging of non-thermal processes. The specifications and concepts for major ngVLA system elements have converged into a Reference Design, which forms the technical and cost basis of a project proposal for the Astro2020 Decadal Survey. An overview of the ngVLA Reference Design will be presented. The concepts for major system elements such as the antenna, receiving electronics, and central signal processing will be described. The major development activities that are presently underway to advance the design will also be described. The current status and future direction of the project will be summarized.
