Air traffic to Reagan National Airport in northern Virginia, the closest airport to downtown Washington, D.C., was suspended,the Federal Aviation Administration said. There was no immediate confirmation the halt in incoming flights was due to the shooting situation.
A White House statement said President Barack Obama has been briefed on the situation.
The headquarters — the workplace for about 3,000 people — is the largest of the Navy’s five system commands. It has a fiscal year budget of nearly $30 billion.
“With a force of 60,000 civilian, military and contract support personnel, NAVSEA engineers, builds, buys and maintains the Navy’s ships and submarines and their combat systems,” the Navy said.
Despite the shooting in Washington, D.C., the Navy base north of Chicago is “open for business,” said Ken Cronk, a spokesman for the Navy’s Midwest Region.
Cronk declined to say whether extra security measures are in place.
