The U.S. Navy will see a significant jump in the portion of its enlisted female crews aboard both its ballistic-missile submarine force and its attack submarines.

The new plan will start with the Navy’s ballistic-missile submarines prior before 2020, according to the Navy Times:

By 2020, the Navy plans to have women make up 20 percent of the enlisted crew on seven of the 18 Ohio-class submarines, according to the Navy’s latest integration plan. The plan also calls for enlisted women to begin serving on attack submarines after 2020, when the Block IV Virginia-class submarines begin entering the service.

“There are many very capable women with the talent and desire to succeed in the submarine force. Drawing from this talent enables us to maintain our undersea dominance,” said Lt. J.G. Eric Durie, spokesman for Navy Secretary Ray Mabus in a statement to the Navy Times. “For these reasons, we have been working diligently to integrate enlisted women into the submarine force.
