Atlantic Media announced today that it’s planning to release a new digital-first brand targeting the U.S. defense and national security markets. Called Defense One, the mobile-optimized brand will launch this summer, followed by a live event and specific iOS and Android apps in the fall.

According to the company, Defense One will be ad supported and will provide news and analysis for national security leadership, including defense leaders, Congressional offices and committees, contractors and think tanks.

Atlantic Media already has a presence in the government b-to-b space with its Government Executive Media Group, which is where Defense One will be housed and includes the Government Executive and Nextgov brands. Both of those already serve more than 60,000 Department of Defense subscribers, says the company.

The new brand will be modeled after the six-month-old Quartz, which is optimized for desktop, mobile and tablet users and now attracts about 2.3 million monthly uniques, per Omniture numbers.

An events platform will support the brand, with the first planned for this fall. Shortly after that, the company says it will also release a series of e-books.
