What are the primary responsibilities of the STRIKE department in naval operations?

The primary responsibilities of the STRIKE department in naval operations focus on planning and executing air operations that support naval missions. One of the key elements of this department is the management and operation of aircraft, which includes checking and ensuring that aircraft systems are functioning properly, particularly in specific modes that are crucial for various operational scenarios. This encompasses both offensive and defensive readiness, ensuring the aircraft meet the tactical needs of the mission.

Additionally, a strong emphasis is placed on the operational procedures and systems checks that differentiate modes of operation. Modes II and IV may refer to specific operational states that aircraft are required to be in for optimal performance during missions, which is critical for maintaining air superiority and effectively supporting surface forces. Thus, the work done by the STRIKE department in this area is foundational to the success of naval operations.

The other responsibilities outlined in the options provided, while important to naval operations, pertain to different departments or functions and do not specifically align with the core focus of the STRIKE department.
