The NRAO operates a complementary, state-of-the-art suite of radio telescope facilities for use by the scientific community, regardless of institutional or national affiliation: the Very Large Array (VLA), the Robert C. Byrd Green Bank Telescope (GBT), and the Very Long Baseline Array (VLBA).

The NRAO is building two new major research facilities in partnership with the international community that will soon open new scientific frontiers: the Atacama Large Millimeter/submillimeter Array (ALMA), and the Expanded Very Large Array (EVLA). Access to ALMA observing time by the North American astronomical community will be through the North American ALMA Science Center (NAASC).

The NRAO collaborates with the university astronomy community to develop new instrumentation and technology, and helps train the next generation of scientists through its student, co-op, postdoctoral, and Fellowship programs. A new data management system will soon improve every astronomer's access to NRAO data products for research and education.
