Raytheon purchased Blackbird Technologies, a cybersecurity contractor that works with the Defense Department, Special Operations Command and other government clients, for $420 million, the company announced last week.

Located in Herndon, Blackbird will become part of Raytheon’s Intelligence, Information and Services (IIS) division. The company will keep its office and leadership team as a wholly owned-subsidiary of Raytheon, a spokesman said. Blackbird has more than 570 employees nationwide.

“Blackbird expands Raytheon’s already-established footprint in the intelligence community market, while helping to grow our cyber operations and special missions support to the [Defense Department],” Lynn Dugle, president of Raytheon’s IIS division, said.

Founded in 1997, the company makes secure communications products such as Mustang, an app to send encrypted calls and texts on Android and Blackberry devices, and also provides services in the fields of cybersecurity and surveillance to intelligence agencies.

Booz Allen taps former DoD official for fellows program

Booz Allen Hamilton has appointed Robert Hale, the Pentagon’s former comptroller and chief financial officer, as its latest “Booz Allen fellow.” The company’s fellows program, created in 2011, recognizes people who are considered subject-matter experts.

Hale spent more than five years at the Pentagon as undersecretary of defense. He oversaw the Pentagon’s response to sequestration in 2013 and the government shutdown.

“A lot of what I was doing at the Pentagon was change management,” Hale said in a phone interview.

The lessons he learned from those times are something he hopes to carry over to the private sector, he said. One of his key areas of focus will be supporting federal workers, Hale said.

“There are things we need to do to improve the federal service, no doubt,” he said. “But we need to find ways to reassure [workers] that they are doing a good job.”

As a fellow, Hale will speak and write about public policy issues in an external capacity. Within Booz Allen, he will act as an adviser on the company’s projects.

Meanwhile, the Carlyle Group last week sold 10 million shares of Booz Allen worth about $263 million, the latest in a series of stock sales that have pared the private equity’s interest in the McLean-based government consultant and technology services firm.

The sale of Booz Allen shares was the fourth time Carlyle had sold shares in the company, and it no longer is majority owner.

New executive at Leidos

Leidos appointed Michael Leiter its new executive vice president for business development and strategy last week. Leiter, who formerly led the National Counterterrorism Center under the Bush and Obama administrations, most recently worked as a counselor to the chief executive of Palantir Technologies.

Leiter brings “an impressive background and strong track record of strategic, operational and industry expertise to Leidos,” Roger Krone, the company’s chief executive, said in a statement.

He starts his new job on Nov. 17.

Think tank director nominated for Pentagon post

President Obama announced a slew of nominations to key administrative posts last week. Among them was David Berteau, the current senior vice president and director of the national security program on industry and resources at the Center for Strategic and International Studies, a District-based think tank. He has been at the Center since 2008.

Berteau is nominated for the post of assistant secretary of defense for logistics and materiel readiness at the Pentagon. He has held several different positions in the Defense Department.
