Abstract: The ALMA Partnership is currently pursing the highest near-term priority recommended by the ALMA Development Roadmap: to at least double (with an ultimate goal of quadrupling) the system bandwidth with improved receiver sensitivity. This initiative is called the ''ALMA 2030 Wideband Sensitivity Upgrade'' (WSU). By the end of this decade, ALMA will upgrade the entire digital signal chain to support these wider bandwidths with improved efficiency (and hence sensitivity) from the digitizers to the correlator, as well as beginning the gradual upgrade of the receiver bands for wider instantaneous bandwidth and improved performance. In this presentation, I will highlight the tremendous science gains that will be afforded by the WSU, and briefly describe the key technical aspects of the WSU with a focus on the major North American contributions which include the 2nd Generation ALMA Correlator and Band 6v2. This significant upgrade will ensure that ALMA remains at the forefront of scientific discovery well into the next decades.
