BlackBerry [BBRY] said in late March its BlackBerry 10 operating system is the first mobile solution to receive “full operational capability” (FOC) on Department of Defense networks. 

The FOC designation from the Defense Information Systems Agency effectively completes the security approval process for BlackBerry 10, which runs on its Q5, Q10, Z10 and Z30 smartphones.

“As the first mobile solutions provider to achieve FOC, BlackBerry continues to prove why we are the most trusted enterprise mobility platform,” John Sims, president of global enterprise services, said in a statement on the company’s website.

The FOC comes as welcome news to the mobile manufacturer. Once the stalwart of corporate and government networks, BlackBerry has ceded much of its market share to 

Google’s [GOOG] Android and Apple’s [APL] iOS operating systems. The trend may soon take hold in DoD, which has stated its goal to become “device agnostic” and securely support any operating system.
