Crashed US Army Black Hawk unit was responsible for doomsday readiness

By Phil Stewart and Idrees Ali

WASHINGTON (Reuters) - The Black Hawk helicopter that collided with a passenger jet in Washington on Wednesday was on a training flight along a route core to a seldom-discussed military mission to evacuate senior officials to safety in the event of an attack on the U.S., officials say.

The military mission, known as "continuity of government" and "continuity of operations," is meant to preserve the ability of the U.S. government to operate.

Most days, crews like the one killed on Wednesday transport VIPs around Washington, which is buzzing with helicopter traffic.

But U.S. Defense Secretary Pete Hegseth disclosed the Black Hawk crew's ties to the mission during a White House press conference on Thursday, saying they "were on a routine, annual re-training of night flights on a standard corridor for a continuity of government mission."

Still, little of such missions is publicly discussed.

The three soldiers killed in the collision were part of the 12th Aviation Battalion at Fort Belvoir in Virginia, whose responsibilities in a national crisis include evacuating Pentagon officials. Another 64 people were killed in the passenger plane.

The Black Hawk crew, using night vision goggles, flew the training mission along the Potomac River on a path known as Route 4. As the Army comes under scrutiny for operating at night near a busy airport, officials have pointed to the battalion's sensitive operations.

"Some of their mission is to support the Department of Defense if something really bad happens in this area, and we need to move our senior leaders," said Jonathan Koziol, the chief of staff of the Army's Aviation Directorate.

SEPT. 11 EMERGENCY FLIGHTS

The most recent time the U.S. government is known to have activated a continuity of operations mission in an emergency was on Sept. 11, 2001, when al Qaeda hijackers slammed airplanes into the World Trade Center in New York City and the Pentagon, killing almost 3,000 people.

Reuters was able to establish some of the activities of the 12th Aviation Battalion that day.

"The battalion helped transport some senior leaders out of Washington, D.C. to 'hide sites,'" Bradley Bowman, a former Army aviation officer who flew on Sept. 11 as part of the 12th Aviation Battalion.

That evening, Bowman flew a Black Hawk to pick up then-Deputy Secretary of Defense Paul Wolfowitz at one of those sites and fly him back to the Pentagon.

There was just one problem -- the Pentagon's helicopter landing pad used to pick up and drop off VIPs was destroyed.

"We just repositioned and landed in the traffic circle of 395, which had been closed by that point," Bowman said, referring to I-395 highway that loops around the U.S. military's headquarters.

Wolfowitz was quoted in a 2017 book describing going to a "bizarre location that was prepared to survive nuclear war."

The book's author, Garrett Graff, said the site was called Raven Rock Mountain Complex, or "Site R," located just miles from Camp David. It remains one of three main backup facilities for the U.S. government, and the main one for the Pentagon leadership.

"It's 100 percent operational today. There's a team of maybe 100 personnel inside Raven Rock right now, ready to pick up the pieces of the U.S. government," Graff said.
