One-hundred-ten degree heat radiated from the flight deck of the amphibious assault ship USS Boxer (LHD 4) as an MH-60S Sea Hawk helicopter swooped in and dropped a message resurrecting an 80-year-old aircraft-to-ship alternative communication method.

Historically, war tends to accelerate change and drives rapid developments in technology. Even with superior modern capabilities, the US Navy still keeps a foot in the old sailboat days and for good reason.

During the sea battles of WWII, US Navy pilots beat enemy eavesdropping by flying low and slow above the flight deck and dropping a weighted cloth container with a note inside. This alternative form of communication was termed a "bean-bag drop."

During the Doolittle Raid on Tokyo, Japan, a Douglas SBD Dauntless pilot spotted a Japanese patrol vessel approximately 50 miles ahead of USS Enterprise (CV 6). The pilot believed he had been seen by the Japanese and decided not to use his radio but flew his SBD over the Enterprise flight deck and dropped a bean-bag notifying the ship of the Japanese patrol boat ahead.

A video posted by Archive.org shows actual video of a SBD rear gunner dropping a bean-bag down to the Enterprise flight deck that day and shows a sailor picking up the bean-bag, then running to the island to deliver it up to the bridge.

The bean-bag design progressed when USS Essex (CV 9) ran out of them and Navy pilot Lt. James "Barney" Barnitz was directed to provide replacements. Barnitz went to see the Essex Parachute Riggers and out of their innovation, the bean-bag was cut and sown into a more durable form.

Fast-forward 80 years to August 2019, when Boxer's Paraloft shop was tasked to make a new bean-bag specifically for a helo-to-deck drop.

"I started with the original measurements of the bean-bag used on the USS Enterprise in 1942 and built this one to withstand the impact of a drop but also weighed down for an accurate drop," said Aircrew Survival Equipmentman 1st Class Carlos R. Freireizurieta, who works in Boxer's Paraloft shop.
