Tamandaré-class (MEKO A-100)

The development program for this class of stealth frigates was established in 2017 as a core component of a broader national maritime strategy. The primary objective was the systematic replacement of aging surface combatants, including units in service since the mid-1970s and vessels acquired second-hand in the 1990s. Following an international competition involving seventeen countries and a multi-year selection process, a contract for an initial batch of four units was finalized in 2020. Construction of the lead vessel commenced in 2022, with its launch occurring in 2024. Current naval planning includes provisions for a second batch of four additional units to further modernize the surface fleet.

These general-purpose frigates utilize a modular design philosophy intended to facilitate the integration of armament and electronic systems. The hull architecture incorporates a two-island configuration and stealth characteristics to minimize radar cross-section. As multi-mission platforms, they are engineered for anti-aircraft, anti-surface, and anti-submarine warfare. The sensor suite includes an active electronically scanned array radar for multi-target tracking, hull-mounted sonar, and various electro-optical fire control systems. Offensive capabilities are centered on vertical launch systems for surface-to-air missiles, anti-ship missile launchers, and torpedo tubes. Defensive measures consist of a close-in weapon system utilizing air burst ammunition, alongside integrated electronic warfare suites for signals intelligence and countermeasures. The design is also prepared for the future integration of land-attack cruise missiles and features facilities for medium-lift helicopters or remotely piloted aerial systems.

The class is destined for the Brazilian Navy, with the lead vessel scheduled for commissioning in 2026. These warships are intended to function as the primary surface combatants within the national maritime framework, conducting naval operations across the spectrum of maritime conflict. Operational deployment will involve the utilization of organic aviation assets, including anti-submarine and utility helicopters, as well as unmanned aerial vehicles for persistent surveillance. Furthermore, the vessels carry rigid-hulled inflatable boats to support boarding operations and secondary maritime tasks. The deployment of these frigates represents a transition toward a more technologically integrated force capable of sustained multi-domain engagements.
