The Grumman S-2 Tracker was the first purpose-built, single airframe anti-submarine warfare aircraft to enter service with the US Navy. The Tracker was of conventional design with twin engines, a high wing and tricycle undercarriage. The Navy used them until the mid-1970s, with several others remaining in service with other countries into the 21st century.

This plane, an S2F-1, was built in 1957 and was seen at Ellington Field, in Houston, TX. Even if you didn’t see the markings on the side, you know instantly it was a naval plane, as the wings fold up for storage on an aircraft carrier. Every time I see a plane with wings that fold, I instantly think of the Transformers. Some kids never grow up.
