United States Subcritical nuclear test conducted in November last year Third time under the Trump administration

It turned out that the United States was conducting a subcritical nuclear test without a nuclear explosion last November.

The United States has conducted a subcritical nuclear test since February, the third time in the Trump administration.

The National Nuclear Security Administration (NNSA) under the US Department of Energy told NHK on the 15th that it conducted a subcritical nuclear test at a nuclear test site in western Nevada last November.

This experiment was named "Night Shade A".

The NNSA has not disclosed the details of the test, but the United States has conducted a subcritical nuclear test since February, the third time in the Trump administration.

In February 2018, the Trump administration announced a new nuclear strategy, and in order to counter Russia and China, it announced the enhancement of nuclear weapons with suppressed power called "low power nuclear weapons" and modernized nuclear facilities. We have aimed to strengthen our nuclear force by expanding the budget for this.

As it became clear that the Trump administration was conducting a new subcritical nuclear test, strong opposition is expected from anti-nuclear groups and others.
