The Pantera modernization program, initiated to enhance the capabilities of the 34 helicopters acquired by the Brazilian Army in 1988, is an extensive effort to extend the operational life of these aircraft by an additional 25 years. Notably, this approach is aimed at maintaining and upgrading existing assets, presenting a cost-effective alternative to acquiring a new fleet.

The financial aspects of the modernization program are highlighted by a cost that is 35% lower than that of acquiring a new helicopter, aligning with contemporary defense strategies focused on maximizing the utility of existing assets while minimizing expenditure.

The modernized Pantera helicopters, now equipped with advanced features, demonstrate a significant improvement in performance over their predecessors. Among the notable enhancements is a 400 kg increase in payload capacity, advantageous when operating in restricted areas. The operational speed of the modernized Pantera has seen a substantial boost, reaching 260 km/h compared to the previous 220 km/h. Additionally, the range of the aircraft has been extended to 660 km, up from the previous 550 km.

The modernization process, conducted at Helibras, involved a thorough overhaul of key components. New wiring has been integrated into the helicopters, ensuring improved functionality and reliability. The engine hood has been redesigned for enhanced aerodynamics, and a new Arriel 2C2CG engine has been installed, providing a 40% increase in power. These modifications collectively contribute to improved overall performance and efficiency.

The cockpit of the Pantera has undergone a significant transformation. The introduction of a new Glass Cockpit panel, compatible with Night Vision Goggles (NVG), reflects advancements in avionics technology. The incorporation of a four-axis autopilot system enhances flight control precision, contributing to safer and more efficient operations. The increased autonomy and speed, coupled with reduced pilot workload, underscore the modernized Pantera's capabilities.

The Eurocopter AS565 Panther, from which the HM-1A Pantera is derived, is a medium-weight multi-purpose twin-engine helicopter with a proven track record in various military roles. Its adaptability in combat assault, fire support, anti-submarine warfare, anti-surface warfare, search and rescue, and medical evacuation makes the Pantera a versatile asset for the Brazilian Air Force.
