2.T18.002-21 is an integrated air-to-air combat training system used in the Polish Air Force. This system allows various aircraft to train together in an interactive environment to improve their individual combat skills. The system is composed of ground based equipment, such as a network of radar systems, and airborne equipment, such as attachable pods that monitor the action in the sky. The radar systems track aircraft movements and communicate the data to the participants and can be used for real-time analysis of their performance. The pods attached to the aircraft provide a visual and acoustic representation to the pilot of the enemy aircraft's movements, allowing for more realistic engagement scenarios. All of this data is collected in a central command position, where it can be analysed and used to determine how pilots performed against each other and where they can be improved. The system provides an exceptional level of immersion, allowing pilots to get immediate feedback on their performance and practice skills that can't be replicated in solo training scenarios.
