What phase follows after flight school and the Fleet Replacement Squadron?

After completing flight school and the Fleet Replacement Squadron, the next phase typically involves the Fleet Squadron Tour. This phase is crucial as it allows newly graduated aviators to gain real-world operational experience with their assigned fleet squadrons. During this tour, they will apply the skills and knowledge acquired in training, participating in various missions that include tactical operations, flight training, and enhancing their proficiency in their specific aircraft. This operational environment is vital for developing competence and confidence as a military aviator before potentially moving on to advanced tactical training or other career opportunities.

The other options represent distinct paths or additional training that might come later in the career progression, but they do not immediately follow the critical experience gained in the Fleet Squadron Tour.
