The complete MPA/ASW tool set

As a marine patrol aircraft, the RAS 72 offers three significant advantages: high performance, completed reliability and low operating costs. It was developed based on German technology and on our experience with ATR family maintenance. Its state-of-the-art mission equipment makes it adaptable for the most varied of tasks.

Case Study

MPA Sea Eagle

The sea eagle is a cost-efficient marine patrol aircraft (MPA) with anti-submarine warfare capability and advanced technology for situational awareness. The aircraft is based on the ATR 72, the market leader in turboprop regional aircraft.

Basic configuration

In its basic configuration, the aircraft is equipped with a multimode long-haul radar and an EO/IR sensor for air, maritime and ground surveillance. It also incorporates a sonar recognition system with sonobuoy launchers and two mounting suspensions for weapons systems in defense against naval and submarine attacks.

Systems

The installed mission systems and sensors are controlled by the Aerodata AeroMission system. The AeroMission can display feeds from the sensors installed on all control stations and has a sensor fusion algorithm which provides the team on board with extensive situational awareness. We delivered two sea eagles, ready for use, converted on the basis of the twin-engine ATR 72 turboprops, to the Pakistani Navy in 2018 and 2019.
