KC‑390 Modular MPA Kit
- Embraer proposed a modular kit to equip KC‑390 transports with surface and sub‑surface sensors, creating an MPA variant. - The concept would add P‑8‑like detection and coordination capabilities to the KC‑390 Millennium airframe. - Modular conversions could offer flexible maritime patrol capacity without procuring wholly new aircraft fleets (x.com).
Embraer is studying a plug-in mission kit that would turn its KC-390 transport into a maritime patrol aircraft without permanently remaking the jet. (navalnews.com) A maritime patrol aircraft is a long-range scout for the sea: it uses radar, sensors and operator consoles to find ships, track submarines and direct other forces. Embraer and the Brazilian Air Force signed an agreement in Brasília in December 2024 to study that role for the C-390 Millennium, with a focus on intelligence, surveillance, reconnaissance and maritime patrol. (navalnews.com) The key idea is modularity. At LAAD Defence & Security on April 1, 2025, Embraer, Brazil and Portugal presented a conceptual roll-on/roll-off mission system that would let a KC-390 take on surveillance work while keeping its existing multi-mission role. (aeroflap.com.br) That matters for air forces that already fly the KC-390 and do not want to buy a separate fleet just for ocean surveillance. Embraer said the studies identified options to add mission systems, sensors, operator workstations and weapons to the aircraft. (aeroflap.com.br) The baseline aircraft was built as a transport and tanker, not a sub hunter. Embraer says the KC-390 carries up to 26 tons, cruises as a jet at up to 470 knots, and already has tactical radar, modern communications and self-protection systems that can support more specialized missions. (navalnews.com) (embraer.com) Embraer has been building the case that the airframe can swap jobs quickly. In December 2024, the Brazilian Air Force ordered a second Modular Airborne Fire Fighting System unit, a package Embraer said can be quickly installed on any KC-390 in the fleet. (aviationnews.eu) Portugal joined the surveillance studies on April 1, 2025, bringing in a second operator of the aircraft alongside Brazil. By May 30, 2025, Aviation Week reported that Embraer was collecting requirements from the Brazilian and Portuguese air forces and aiming to finish the studies by the end of 2026. (aeroflap.com.br) (aviationweek.com) The sales angle is straightforward: the KC-390 is already in service with Brazil, Portugal and Hungary, and Embraer says it has also been selected by the Netherlands, Austria, the Czech Republic, South Korea and Sweden. A modular patrol package would give that installed base a way to add maritime surveillance with an aircraft they already know how to maintain and fly. (navalnews.com) (aviationnews.eu) The project is still a study, not a fielded variant. But if Embraer can make the kit work as advertised, the KC-390 would move closer to being not just a cargo jet with a rear ramp, but a platform air forces can reconfigure for the sea.
