## 1 Introduction  
Based on the Brazilian Federal Constitution [1], the Brazilian Navy (BN) aims to prepare and employ naval power contributing to the defense of the country, guaranteeing constitutional powers and ensuring law and order, fulfilling the duties provided by the law, with emphasis on those related to the Maritime Authority, aiming to contribute to safeguarding national interests [2]. Even in a time of peace, it is essential that the BN has modern equipment to guarantee its sovereignty and strategic interests that support Brazil foreign policy and positions in international forums [3]. In 2019, a document entitled Naval Policy (NP) was promulgated by the BN. The NP guides, following the National Defense Strategy (NDS), the BN strategic planning, whose compliance imposes the availability of marine forces able to act in line with the political-strategic and economic magnitude of Brazil in the international scenario [4]. According to the objectives and guidelines established in the National Defense Policy (NDP) and NDS, high-level documents that condition the preparation and use of the Armed Forces, BN is responsible for the use of the Naval Power, providing sufficient capacity and credibility to deter any adverse forces from conducting hostile actions in Brazilian Jurisdictional Waters (BJW) [4]. The presence of marine units in the South Atlantic, where the \"Blue Amazon\" is included, and in the rivers of the Amazon and Paraguay-Parana basins will be an essential factor for strengthening this dissuasion. Thus, the Force must be prepared both to act in an interstate crisis and to monitor and suppress the actions of adverse groups practicing illegal activities in BJW [5]. Highlighting that the addressed problem provides influence in local and external perspectives presented in the context [6]. Since the first version of the NDS set the mission to raise the level of the Brazilian Armed Forces, each Force has presented its conception of military change, the Brazilian Navy prioritized modernization [7]. The Naval Power comprises the ability to use the sea and inland waters, at the disposal of a force with expeditionary property, in a permanent condition of prompt employment, ensuring the projection of power over the land. This force is composed of an amphibian conjugate: Naval Force, an Operative Group of Marines, and the Air Force, in a position to fulfill missions related to the basic tasks of the Naval Power [8]. In this context, among the military aircrafts necessary for carrying out aero-naval missions, we highlight the use of attack helicopters, suitable for reconnaissance and air fire support activities, due to their large number of armaments and ability to engage air and ground targets. This function is currently performed by helicopters of smaller size and with low firepower, although, could be replaced by more modern means specific for this purpose, thus, ensuring better performance in the execution of such activities [9]. Thus, it would be of great value to the Marine Corps that the BN acquires new helicopters with the capabilities to provide the necessary fire support to Amphibious Operations, capable of carrying out advanced aerial reconnaissance and offensive air support, mainly in the fight against armored vehicles and enemy troops on the ground. The NDS provides, under the leadership of the Ministry of Defense, the acquisition of transport helicopters, reconnaissance, and attack, acquired with commercial, industrial, and technological compensation [10]. Considering this need, due to the quantity, diversity, and complexity of existing models today, the task of selecting a helicopter that is more appropriate to BN's needs, aiming to provide support to the operations performed by the CFN, is not a simple task.
