Boeing is gearing up to modify its ubiquitous twin-jet, single-aisle airliner into a Navy patrol bomber called the Multi-Mission Maritime Aircraft, or MMA. The plane will have a variety of sensors to pinpoint a submarine’s location: anti-submarine radar, an electro-optical-infrared camera and Magnetic Anomaly Detection, or MAD. Rotary magazines will drop sonar sonobuoys.
