In this paper, we introduce the virtual role playing (VRP) concept using intelligent agents. The objective of VRP is to provide training to incomplete teams is by emulating missing human operators. Keystones of this system are the mandatory collaboration between the agents and the homogeneity of the interactions between the intelligent agents and the human operators in order to achieve a common target. This VRP system, as used in the NOVA 1 project, aims at providing a training environment for a maritime patrol aircraft (MPA) in an antisubmarine warfare (ASW) mission.
