A fourth sailor faces a court-martial in connection with the recording and sharing of videos that showed female officers and trainees undressing for showers aboard the submarine USS Wyoming.

A hearing is scheduled for Tuesday afternoon for Petty Officer 3rd Class Cody Shoemaker.

Officials say seven sailors stationed at Kings Bay Naval Submarine Base on the Georgia coast have been charged in connection with the videos. Navy prosecutors say the videos were traded by sailors "like Pokemon" cards for energy drinks and other items. The case has been a blemish on the Navy's integration of women into the U.S. submarine force, which had been all-male until 2011.

Three sailors pleaded guilty last week.
