USS Macon (ZRS-5)
USS Macon (ZRS-5) was a rigid airship built and operated by the United States Navy for scouting and served as a "flying aircraft carrier", launching Curtiss F9C Sparrowhawk biplane fighters. In service for less than two years, in 1935 Macon was damaged in a storm and lost off California's Big Sur coast, though most of the crew were saved. The wreckage is listed as USS Macon Airship Remains on the U.S. National Register of Historic Places.
Less than 20 ft (6.1 m) shorter than Hindenburg, both the Macon and "sister ship" USS Akron (ZRS-4) were among the largest flying objects in the world in terms of length and volume. Although the hydrogen-filled Hindenburg was longer, the two sisters still hold the world record for helium-filled airships.
