Overview
Ares Aeroespacial e Defesa is a Brazilian aerospace and defense company that has operated since 2010 as a subsidiary of Israel-based Elbit Systems Ltd. The company serves the Brazilian defense market through the planning, design, development, manufacture, integration, maintenance, and commercialization of defense equipment and mission systems. Its stated activities are organized around three principal business lines: remotely operated weapon stations, naval systems, and optical and electro-optical systems. Ares's role is closely connected to Elbit Systems' broader strategy of developing local industrial and technological capacity in important defense markets. Rather than being positioned primarily as a consumer-facing brand, Ares operates as a specialist defense contractor and systems integrator. Its work can encompass equipment production, platform integration, lifecycle support, maintenance, and the adaptation of Israeli-origin technologies to the requirements of Brazilian military customers. One of the company's most significant publicly reported programs is REMAX, a remotely controlled weapon station supplied to the Brazilian Armed Forces. In 2017, Ares signed a contract valued at approximately $100 million to provide remote-controlled weapon systems over a five-year period. The systems were intended for use on armored and logistics vehicles involved in troop transport, border patrol, peacekeeping, and combat-support missions. The contract represented a follow-on order and reinforced Elbit Systems' view of Brazil as an important market. Ares has also participated in naval modernization. In 2018, it installed an Atena electro-optical and infrared surveillance system aboard Defensora, a Niterói-class Brazilian Navy frigate. The installation was reported as a potential precursor to fitting comparable systems on the class's other ships, including Niterói, Constituição, Liberal, Independência, and União. This work illustrates the company's emphasis on integrating sensor and surveillance capabilities into existing military platforms rather than focusing only on new-build equipment. Publicly available reference material provides limited information about Ares's standalone corporate structure, leadership, revenue, ownership percentage, facilities, and activities outside Brazil. The company is best understood as a Brazilian operating subsidiary and defense-technology platform within the Elbit Systems group, with capabilities spanning remote weapon systems, naval electronics, surveillance, and electro-optical integration.
History
Ares Aeroespacial e Defesa is a Brazilian defense company established as an Elbit Systems subsidiary and operating since 2010. Its business is focused on military equipment and systems rather than civilian aerospace products. The company describes its scope as covering the complete or near-complete lifecycle of selected defense technologies: planning, design, development, manufacture, integration, maintenance, and commercialization. The company's activities are organized into three principal areas. The first is weapon stations, including remotely operated systems that allow a vehicle crew to employ weapons from a protected position inside the platform. The second is naval systems, covering equipment and integration work for naval vessels. The third is optical and electro-optical systems, including sensors used for observation, surveillance, targeting, and situational awareness. These areas place Ares at the intersection of defense manufacturing, electronics, platform modernization, and systems integration. Ares's corporate development should be viewed in the context of Elbit Systems' expansion of its international presence and its efforts to establish local capabilities in major defense markets. Through its Brazilian subsidiary, Elbit can provide equipment and support adapted to Brazilian military requirements while maintaining access to the parent group's technology base. Public sources do not provide a detailed account of the subsidiary's original incorporation, facilities, workforce, or early contracts, so the company's initial development cannot be reconstructed in detail. The best-documented stage in Ares's history came in 2017, when it signed an approximately $100 million contract to supply REMAX remote-controlled weapon systems to the Brazilian Armed Forces. The order was scheduled for delivery over five years. REMAX systems were intended for armored vehicles and logistics vehicles used in troop transportation, border patrol, peacekeeping, and combat-related missions. The order was described as a follow-on contract, indicating that the Brazilian customer had an earlier relationship with the technology or supplier. Elbit Systems President and Chief Executive Officer Bezhalel Machlis characterized Brazil as an important market for the group and described the award as a further REMAX contract for the Brazilian Army. The company subsequently demonstrated its naval and sensor-integration role. In 2018, Ares installed an Atena electro-optical infrared surveillance system aboard Defensora, a Niterói-class frigate of the Brazilian Navy. The system was intended to provide enhanced observation and surveillance capability. Reporting indicated that the work could lead to the installation of Atena systems on the class's remaining frigates: Niterói, Constituição, Liberal, Independência, and União. This potential expansion showed how Ares's business could support the modernization of legacy platforms as well as the delivery of standalone equipment. Available reference material does not establish a complete list of Ares contracts, product variants, senior executives, revenue, ownership details beyond its Elbit Systems affiliation, or international operations. The documented record nevertheless identifies Ares as an active Brazil-oriented defense technology company whose principal capabilities are remote weapon stations, naval systems, and electro-optical surveillance and integration.
