arXiv:2207.12084v2 Announce Type: replace Abstract: The Aerospace Simulation Environment (Ambiente de Simula\c{c}\~ao Aeroespacial -- ASA in Portuguese) is a custom-made object-oriented simulation framework developed mainly in C++ that enables the modeling and simulation of military operational scenarios to support the development of tactics and procedures in the aerospace context for the Brazilian Air Force. This work describes the ASA framework and its main features: a distributed architecture for coordinating multiple simulation machines, a modular structure that allows models to be loaded at runtime, a batch execution mode for simulating multiple scenarios with varied initial conditions, and an integrated data analysis platform for post-processing simulation results. In addition, we present a list of recent studies that have used ASA in applications related to decision support and autonomy in air combat scenarios.
