Next Generation Very Large Array

The Next Generation Very Large Array (ngVLA) is a 1-100 GHz radio telescope array/interferometer beginning development, to be a step up from the Atacama Large Millimeter Array (ALMA) and the Very Large Array (VLA), with ten times the collection area of either and support for a range of baselines up to VLBI distances. Plans call for a main array and a short-baseline array in New Mexico, regional sites supporting up to 300-km baselines, and a few very-distant sites for thousands of km. Designing began around 2021, with the intent to prototype in the early 2020s, begin construction in 2025, begin partial operation in 2029, and begin full operation in 2035.
