Joe Biden says submarine he has commissioned will enhance global security

President Joe Biden has commissioned the USS Delaware, a nuclear attack submarine, saying it would enhance national security – though he made no reference to the global turmoil from Russia's invasion of Ukraine.

"As the commander in chief, I believe it is our sacred obligation as a nation to prepare and equip those troops that we send into harm’s way and to care for them and their families when they return home," he told a crowd of invited guests and dignitaries assembled on a sunny but chilly spring day on a restricted part of the dock in Wilmington.

The latest Navy ship to carry the Delaware name, the president said in brief remarks, 'is part of a long tradition of serving our nation proudly and strengthening our nation’s security… not just us, but our allies and partners around the world as well.

In April 2020, with the coronavirus pandemic spreading across the United States, the Delaware was commissioned while underwater, a first for a Navy vessel. Since then it has been in training. After the ceremony, the president took a private tour of the Delaware. He did not respond to questions from reporters about Ukraine.

First lady Jill Biden is the submarine’s sponsor, a role meant to bring a vessel luck. During her remarks, she said: "Officers and crew of the USS Delaware, man our ship and bring her to life.”
