Why the Navy Is Relying on WWII-Era Communications

The U.S. Navy, anticipating a future when a high-tech enemy could read its electronic communications, is going back to a hack-proof means of sending messages between ships: bean bags. Weighted bags with messages inside are passed among ships at sea by helicopters.

In a future conflict with a tech-savvy opponent, the U.S. military could discover even its most advanced, secure communications penetrated by the enemy. Secure digital messaging, voice communications, video conferencing, and even chats could be intercepted and decrypted for its intelligence value. This could give enemy forces an unimaginable advantage, seemingly predicting the moves and actions of the fleets at sea with uncanny accuracy.

Last week, a MH-60S Sea Hawk helicopter delivered a message from the commander of an amphibious squadron to the captain of the amphibious assault ship USS Boxer. The helicopter didn’t even land to deliver it, dropping it from a hovering position before flying away. The message was contained in a bean bag dropped on the Boxer’s flight deck.

The bean bag system, as Military.com explains it, is nearly eight decades old. The system dates back to April 1942, when a SBD Dauntless dive bomber assigned to the USS Enterprise was flying a scouting mission ahead of the USS Hornet. Hornet, about to launch sixteen B-25 Mitchell bombers on a raid against Japan, was traveling in extreme secrecy to preserve the element of surprise. The Dauntless pilot encountered a Japanese civilian ship and, fearing he had been spotted, dropped a message in a bean bag on the deck of Hornet.

[...] Bean bags aren’t the only old tech the Navy is bringing back. In 2016, NPR reported that the service was reintroducing sextants as a navigational tool for officers. The U.S. armed services are heavily reliant on the satellite-based Global Positioning System for navigation, making jamming or spoofing GPS signals a major priority for adversaries. If they’re successful, the military must be able to navigate from Point A to Point B the old fashioned way—by sextant if necessary.

    I wonder if our current CinC has had any input on the "are you really sure your systems won't be HAX0RED?" Seems like the kind of obtuse question he's good at asking, and in this case I think we're better off for whoever has asked it having done so.

    Still, I'd love to see the drill when an aircraft carrier is navigated into New York harbor with zero electronic navigation aides... that's gonna require the dress-browns on the bridge.
