Final answer:
The Air Force currently uses the Enhanced On-Board Load Handling System (EOBLHS) and the GAU-8/A Avenger loading system for 30 mm ammunition. These systems are used in aircraft such as the AC-130 and A-10 Thunderbolt II to ensure efficiency and readiness for combat.
Step-by-step explanation:
The two 30 mm ammunition loading systems currently being used in the Air Force are the Enhanced On-Board Load Handling System (EOBLHS) and the GAU-8/A Avenger loading system. The EOBLHS is an advanced system designed to load ammunition into aircraft such as the AC-130 gunship more efficiently, with automation features that reduce manpower requirements and improve loading times. On the other hand, the GAU-8/A Avenger loading system is specifically designed for the A-10 Thunderbolt II aircraft and includes a specialized drum that allows the 30 mm ammunition to be loaded into the aircraft's rotary cannon. These systems are essential for maintaining the effectiveness of the Air Force's aircraft in combat situations, ensuring that they are armed and ready for any mission.
