Air Development Squadron Six (VX-6 or AIRDEVRON SIX, commonly referred to by its nickname, "puckered penguins") was a United States Navy Air Development Squadron based at McMurdo Station, Antarctica. Established at Naval Air Station Patuxent River, Maryland on 17 January 1955, the squadron's mission was to conduct operations in support of Operation Deep Freeze, the operational component of the United States Antarctic Program.

Using the tail code XD, the squadron flew numerous fixed-wing aircraft and helicopters over the course of its existence—many of which were pioneering endeavors. For example, the first air link between Antarctica and New Zealand was established by men and aircraft of VX-6 in 1955. The following year, a ski-equipped R4D Dakota of VX-6 became the first aircraft to land at the South Pole. In 1961, the first emergency midwinter medical evacuation flight was conducted from Byrd Station to Christchurch. In 1963, an LC-130F Hercules of VX-6 made the longest flight in Antarctic history. In 1967, a United States Navy LC-130F of VX-6 completed the first scheduled winter flight to Antarctica, landing at Williams Field.
