The acquisition of a new satellite communications system for the multi-purpose landing platform dock (LPD) NDM Bahia (G40) by the Brazilian Navy (Marinha do Brasil) represents a significant leap forward in bolstering the capabilities of this multi-purpose landing platform dock. The enhancements span from commercial communications to advanced weaponry, navigation systems, satellite TV, medical support, and, notably, a state-of-the-art satcom terminal. The defense publication Janes reported that the procurement process, launched through the Brazilian Naval Commission in Washington, DC, underscores the meticulous planning and strategic vision behind fortifying the NDM Bahia’s satcom infrastructure.

The evaluation of proposals from undisclosed companies exhibits a thorough consideration of the best-fit technology for seamless integration and efficient operation within the ship’s framework. The utilization of the X-band dual antenna satcom terminal aligns with Brazil’s reliance on the SISCOMIS system for military satellite communications. Leveraging the SGDC-1 satellite for X-band transmission reinforces the ship’s connectivity and interoperability within the broader military communication network. Moreover, the integration of the Sistema Integrado de Comando y Control de la Marina de Brasil (Sic2MB) system, along with radar and electronic support measures (ESM) systems, underscores the holistic approach toward modernizing the ship’s command, control, and defensive capabilities.

The NDM Bahia, formerly the French Navy’s Foudre-class landing platform dock Siroco (L9012), represents a significant addition to Brazil’s naval assets. The vessel’s impressive specifications, including its displacement, dimensions, and propulsion systems, emphasize its robustness and adaptability for diverse operational scenarios. The vessels are both propelled by two controllable pitch propellers powered by two SEMT-Pielstick 16 PC 2.5 V400 diesel engines creating 15,480 kW (20,760 bhp). The ships have permanent accommodation for 470 troops but can support up to 2,000 for three days. They have capacity for 1,080 t (1,060 long tons; 1,190 short tons) of vehicles and cargo stowed in a 1,360 m2 (14,600 sq ft) area. The Foudre class carry large stowage areas which can be used to ferry battle tanks and vehicles.

Brazil’s acquisition of the Siroco in 2015, following its retirement from the French Navy, signified a strategic move toward enhancing the nation’s amphibious and aerial capabilities. The vessel’s role in supporting UN stabilization missions in Haiti and its humanitarian aid contributions, notably through its hospital center, showcase its versatile utility beyond traditional naval operations. The incorporation of Eurocopter EC725 and Sikorsky SH-60 Seahawk helicopters within the ship’s airborne group further amplifies its operational reach and effectiveness in various mission profiles. The comprehensive upgrades and adaptations made to the NDM Bahia since its acquisition underscore Brazil’s commitment to bolstering its naval prowess, ensuring operational readiness, and contributing significantly to both national and international maritime missions.
