A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. [1] The term typically refers to magnetometers used by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field ).
The Lockheed P-3 Orion is a four-engined, turboprop anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s. Lockheed based it on the L-188 Electra commercial airliner; it is easily distinguished from the Electra by its distinctive tail stinger or "MAD" boom, used for the magnetic anomaly detection (MAD) of submarines.
A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. The term refers specifically to magnetometers used either by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field )Magnetic anomaly detectors were first ...
The Bangui magnetic anomaly in central Africa and the Kursk magnetic anomaly in eastern Europe (both in red) In geophysics, a magnetic anomaly is a local variation in the Earth's magnetic field resulting from variations in the chemistry or magnetism of the rocks. Mapping of variation over an area is valuable in detecting structures obscured by ...
[12] [13] For example, the Hoxa channel into Scapa Flow was provided with two guard loops followed by eight mine loops in echelon. [14] An indicator loop gave the first warning of the 1942 attack on Sydney Harbour, when it detected the midget submarine M-14, but that signal was ignored, owing to civilian traffic in the area. The submarine was ...
The blimps were equipped with the ASG radar, that had a detection range of 90 mi (140 km), sonobuoys, and magnetic anomaly detection (MAD) equipment. The K -ships carried four 350 lb (160 kg) depth bombs , two in a bomb bay and two externally, and were equipped with a machine gun in the forward part of the control car.

Major fuselage changes were made, including an internal weapons bay, an extended nose for radar, a new tail with electronic warfare (ESM) sensors mounted in a bulky fairing, and a MAD (magnetic anomaly detector) boom. After the first flight in May 1967, the RAF ordered 46 Nimrod MR1s. [10] The first example entered service in October 1969. [11]
