About this Unit
**Military History of Fuels – VX-4:**
VX-4, known as Air Test and Evaluation Squadron Four, was a United States Navy unit established in 1950 at Naval Air Station Point Mugu, California. While its primary mission focused on operational testing and evaluation of naval aircraft and weapons systems, VX-4 also maintained specialized support elements, including a Fuels division. The Fuels team was critical in ensuring the safe storage, handling, and delivery of aviation fuel for test flights and experimental aircraft, often working under stringent safety protocols due to the sensitive nature of the squadron's operations. Throughout its history, VX-4’s Fuels personnel contributed significantly to successful flight test programs, enabling advances in naval aviation tactics and technology until the squadron’s merger with VX-5 to form VX-9 in 1994.
Historical Facts
•
VX-4 Origins: VX-4, also known as Air Test and Evaluation Squadron Four, was established in 1946 at NAS Patuxent River, Maryland, before moving to NAS Point Mugu, California.
•
Fuels Division: The “Fuels” unit within VX-4 was responsible for evaluating and testing aviation fuels, lubricants, and related systems to ensure aircraft operational readiness and performance.
•
Cold War Role: During the Cold War, VX-4’s Fuels section played a key role in testing fuel formulations for advanced jet fighters to keep pace with Soviet advancements.
•
Phantom II Testing: VX-4 was famous for testing the F-4 Phantom II, and the Fuels unit developed and validated fuel blends to maximize the aircraft’s speed and range.
•
Innovative Additives: The Fuels team evaluated anti-icing and anti-corrosion additives, helping reduce maintenance downtime and improving flight safety for naval aircraft.
•
“Vandy One” Legacy: VX-4 was known for its iconic black-painted F-4 and F-14 test aircraft, nicknamed “Vandy One.” The Fuels unit contributed to their unique paint chemistry for stealth and durability.
•
Fleet Support: Fuels personnel from VX-4 regularly trained fleet maintenance crews on new fuel handling and storage procedures, making them a vital link between test and operational squadrons.
•
Desert Operations: The unit helped develop specialized fuel blends for aircraft operating in extreme environments, like deserts, to prevent vapor lock and maintain performance.
•
Environmental Stewardship: In the 1980s, the Fuels unit participated in early efforts to reduce environmental impact by evaluating lead-free and alternative aviation fuels.
•
VX-4 Disestablishment: VX-4 was disestablished in 1994, merging with VX-5 to form VX-9. The expertise and legacy of the Fuels division continued within the new unit, supporting advanced Navy aircraft development to this day.
