When was AFF used in the Navy?
The Aviation Fuels Fuel (AFF) is a type of aviation fuel that has been widely used by the US Navy and other military organizations for many decades. AFF is a kerosene-based fuel that is designed to provide a stable and consistent energy source for military aircraft, including jets, helicopters, and turboprop planes.
Early Years
The first recorded use of AFF by the US Navy dates back to 1939. During this time, the Navy was transitioning from gasoline-powered aircraft to diesel-powered aircraft, and AFF was seen as a more suitable fuel for the new diesel engines. Initially, AFF was used for marine aircraft, including the Douglas TBD Devastator torpedo bomber and the Grumman F4F Wildcat fighter plane.
WWII and the Birth of AFF as We Know It Today
During World War II, the US Navy saw a massive expansion of its aviation program, with AFF playing a crucial role in supporting the war effort. AFF was standardized and refined to meet the demands of the war, and its production increased significantly to keep up with the growing need.
Some of the most notable aircraft that used AFF during WWII include:
- F4U Corsair (fighter plane)
- TBM Avenger (torpedo bomber)
- PBY Catalina (patrol bomber)
Post-War and the Cold War Era
After WWII, the US Navy continued to rely heavily on AFF as its primary aviation fuel. During the Cold War, the Navy saw significant advancements in aviation technology, including the introduction of jet-powered aircraft such as the F-14 Tomcat and the A-4 Skyhawk.
The Navy also standardized its AFF blends during this period, creating two main types of fuel:
- AFF-T, a turbine fuel used in jet engines
- AFF-C, a piston fuel used in reciprocating engines
Modern Era and Current Use of AFF
Today, the US Navy still uses AFF as its primary aviation fuel, with some minor variations in composition and quality control. F-18 Hornet and Super Hornet, F/A-18E/F, F-35C Lightning II are some of the latest aircraft that use AFF.
Some of the key features and benefits of AFF include:
- High-energy density: AFF contains a higher energy density than gasoline, allowing it to provide a longer duration of flight for military aircraft.
- Stable performance: AFF is designed to provide a consistent energy output, making it an ideal choice for military applications.
- Low maintenance: AFF requires less maintenance than gasoline, as it is less prone to phase separation and other problems.
Conclusion
In conclusion, AFF has a long and storied history in the US Navy, dating back to the 1930s. From its early days as a gasoline-based fuel to its current role as a standardized, refined kerosene-based fuel, AFF has played a crucial role in supporting the Navy’s aviation program.
