WASHINGTON - The US Navy’s top admiral on Tuesday condemned two new racist incidents involving hate symbols on warships, which sources said included a noose that was left on a Black sailor’s bed.

The incidents, which occurred in recent weeks, underscore deep concerns about racism in the ranks. The cases come as Pentagon leaders face growing pressure to show progress in combating extremism after current and former military servicemembers were found to have participated in the siege of the US Capitol on Jan 6.

While details of the incidents were not given, Chief of Naval Operations Admiral Mike Gilday cautioned in a message to the fleet on Tuesday that racial divisions in the ranks cut at the military’s ability to protect the country

In one case being investigated by the Naval Criminal Investigative Service (NCIS), hate speech graffiti was discovered in a bathroom aboard the USS Carl Vinson aircraft carrier. NCIS is also investigating the noose incident aboard the guided-missile cruiser USS Lake Champlain. Two officials who spoke on condition of anonymity confirmed the details.

While he did not give details of the incidents, Chief of Naval Operations Admiral Mike Gilday cautioned in a message to the fleet on Tuesday that racial divisions in the ranks cut at the military’s ability to protect the country.

“If we must first question the intentions of our shipmate standing the watch with us, now, and especially, when taking fire, we will fail when the Nation needs us must in combat,” Gilday said.

Gilday’s message came days after Lloyd Austin, the first Black defense secretary, ordered military-wide standdowns, pausing regular activity, to address white nationalism and other extremism.

Gilday acknowledged that addressing extremism is a leadership issue, adding “we will own this.””Some sailors may think their voices do not matter right now, or feel frustrated seeking to be seen and be heard. But let me be clear, each of your voices matter,” Gilday said.’

“This standdown is another in our efforts to listen, to learn, and to improve.”
