ALBUQUERQUE, N.M. (AP) — A top U.S. nuclear security official and the leaders of three key national laboratories doubled down Friday on the push to modernize the country’s nuclear arsenal and the science and technology that back it up.

During a virtual forum, the officials acknowledged global pressures that include more investment by Russia and China in nuclear weapons and advanced laser capabilities. They said the United States is at a “tipping point” when it comes to maintaining its own arsenal and that boosting production capabilities cannot be put off.
