What is the main purpose of making an aircraft low observable?

The primary purpose of making an aircraft low observable is to increase the aircraft's survivability. Low observable technology, often associated with stealth capabilities, minimizes the radar cross-section and infrared signatures of an aircraft. This advancement allows the aircraft to evade detection and tracking by enemy radar systems, enhancing its ability to operate in contested environments. The stealth features contribute to mission success by allowing the aircraft to engage targets and complete objectives while minimizing the risk of being targeted by enemy defenses.

While enhancing fuel efficiency, improving maintenance accessibility, and reducing operational costs are important factors in aircraft design, they do not directly relate to the core function of low observability. The focus on survivability is paramount in military operations, where remaining undetected can significantly impact mission outcomes and overall safety.
