The Navy's lighter-than-air program was conducted at Lakehurst through the 1930s. It was the site of the 1937 LZ 129 Hindenburg airship disaster. During World War II, anti-submarine patrol blimps were operated from Lakehurst. Since the 1950s, Aviation Boatswain's Mates have been trained at Lakehurst to operate catapults and arresting systems on aircraft carriers. Lakehurst conducts the unique mission of supporting and developing the Aircraft Launch and Recovery Equipment and Support Equipment for naval aviation. The Electromagnetic Aircraft Launch System and the Advanced Arresting Gear system that will replace the existing steam catapults and the Mk-7 arresting gear are being developed and tested at Lakehurst at full-scale shipboard representative test facilities here.
