What type of aircraft is commonly associated with using a gaseous oxygen supply system?

Fighter aircraft are commonly associated with using a gaseous oxygen supply system primarily due to their operational requirements at high altitudes and during high-performance maneuvers. These aircraft are designed to operate in environments where the atmosphere has significantly lower oxygen levels, making it crucial for the pilot to have a reliable oxygen supply to maintain cognitive function and physical performance.

The gaseous oxygen system in fighter jets is essential for ensuring that pilots can breathe normally at high elevations where the air is too thin. It provides the necessary oxygen under extreme conditions quickly, allowing pilots to focus on their missions without being hindered by hypoxia, which can occur when oxygen levels drop too low.

In contrast, other types of aircraft, such as cargo planes, bombers, and tankers, may utilize different types of oxygen supply systems or may not require such systems at all, depending on their operational altitudes and the nature of their missions. Cargo aircraft typically operate at lower altitudes, while bombers and tankers may have varied requirements depending on their design and mission profiles, but they do not universally need a gaseous oxygen supply system like fighters do.
