Question: 601 Lobos is a squadron of the Portuguese Air Force that operates an aircraft that is easily distinguished by its distinctive tail stinger or "MAD Boom", used for what?

full_context: Document 1: Lockheed P-3 Orion: The Lockheed P-3 Orion is a four-engine 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. The aircraft is easily distinguished from the Electra by its distinctive tail stinger or "MAD Boom", used for the magnetic detection of submarines.
Document 2: VAQ-131: Electronic Attack Squadron 131 (VAQ-131), also known as the "Lancers," is a United States Navy tactical jet aircraft squadron specializing in kinetic and non-kinetic Suppression of Enemy Air Defenses (SEAD). They are based at Naval Air Station Whidbey Island, flying the EA-18G Growler and are part of Carrier Air Wing 8, deploying aboard the USS "George H.W. Bush" . Their radio callsign is "Skybolt."
Document 3: Black Bat Squadron: Black Bats () 34th Squadron was the name of a corps of CIA reconnaissance plane pilots and crew based in Taiwan during the Cold War. Citizens of the Republic of China, they flew missions over mainland China controlled by the People's Republic of China (PRC), to drop agents and gathered military signal intelligences around military sites. The 34th Squadron was formed in 1953 and flew its last operational mission in 1967. The squadron's emblem was a bat and seven stars and its formal name was the 34th Squadron of the ROC Air Force. Unit's aircraft included the Boeing B-17G, Douglas A-26C/B-26C Invader, 7 Lockheed RB-69A, Douglas C-54, 11 Fairchild C-123B/K Provider, Lockheed C-130E Hercules, and 3 "black" Lockheed P-3A Orion (149669, 149673, 149678). The P-3As and RB-69As were armed with AIM-9 Sidewinder missiles for self-defense. 34th Squadron specialized in very low level air space penetration (100–200 meters altitude) to hug the ground in order to evade enemy radars and fighter interceptions. Later when operating P-3A, its main mission was flying in international water, 40 miles outside of Mainland China, to collect signal intelligences.
Document 4: 601 Squadron (Portugal): 601 Squadron ""Lobos"" ("Esquadra 601") is a maritime patrol and anti-submarine warfare squadron of the Portuguese Air Force (PoAF), currently based at Beja Air Base. It operates the Lockheed P-3C CUP+ Orion.
Document 5: 751 Squadron (Portugal): The 751 Squadron "Pumas" ("Esquadra 751") is a helicopter squadron of the Portuguese Air Force. It is part of "Grupo Operacional" 61 and it is located in Air Force Base No. 6 (Portuguese: "Base Aérea Nº 6" , BA6), Montijo, south of Lisbon. It operates the AgustaWestland AW101 Merlin. The 751 Squadron motto is ""Para que outros vivam"" (That others may live). More than 3455 lives have been saved by their crews since 1978.
Document 6: Lockheed R6V Constitution: The Lockheed R6V Constitution was a large, propeller-driven, double-decker transport aircraft developed in the 1940s by Lockheed as a long-range, high-capacity transport and airliner for the U.S. Navy and Pan American Airways. Only two of the aircraft were ever built, both prototypes. Although these two planes went into service with the Navy, the Constitution design ultimately proved underpowered and too large for practical airline use at the time. Although the Martin JRM Mars flying boat had a slightly longer wingspan, the Constitution remains the largest fixed-wing aircraft type ever operated by the U.S. Navy.
Document 7: Northrop P-61 Black Widow: The Northrop P-61 Black Widow, named for the American spider, was the first operational U.S. warplane designed as a night fighter, and the first aircraft designed to use radar. The P-61 had a crew of three: pilot, gunner, and radar operator. It was armed with four 20 mm (.79 in) Hispano M2 forward-firing cannons mounted in the lower fuselage, and four .50 in (12.7 mm) M2 Browning machine guns mounted in a remote-controlled dorsal gun turret.
Document 8: Lockheed SR-71 Blackbird: The Lockheed SR-71 "Blackbird" is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed with a reduced radar cross-section.
Document 9: No. 92 Wing RAAF: No. 92 Wing is the maritime patrol wing of the Royal Australian Air Force. It is headquartered at RAAF Base Edinburgh. It is part of the Surveillance and Response Group, and consists of No. 10 Squadron, No. 11 Squadron and No. 292 Squadron. The wing also has a permanent detachment at RMAF Base Butterworth in Malaysia. It operates AP-3C Orion maritime patrol aircraft in roles including anti-submarine- and anti-surface surveillance and warfare for which the aircraft are equipped with torpedoes and Harpoon anti shipping missiles. It is also responsible for long range intelligence, surveillance, reconnaissance and maritime attack missions and search and survivor supply missions.
Document 10: 601st Squadron (JASDF): The 第601飛行隊 (601st Squadron , dai603hikoutai ) is a squadron of the Airborne Early Warning Surveillance Group of the Japan Air Self-Defense Force (JASDF) based at Misawa Air Base in Aomori Prefecture, Japan. It is equipped with Northrop Grumman E-2C Hawkeye aircraft.
Document 11: Northrop Grumman E-2 Hawkeye: The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft. This twin-turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which was rapidly becoming obsolete. The aircraft's performance has been upgraded with the E-2B, and E-2C versions, where most of the changes were made to the radar and radio communications due to advances in electronic integrated circuits and other electronics. The fourth major version of the Hawkeye is the E-2D, which first flew in 2007. The E-2 was the first aircraft designed specifically for its role, as opposed to a modification of an existing airframe, such as the Boeing E-3 Sentry. Variants of the Hawkeye have been in continuous production since 1960, giving it the longest production run of any carrier-based aircraft.
Document 12: Lockheed EC-121 Warning Star: The Lockheed EC-121 Warning Star was a United States Navy and United States Air Force Airborne early warning and control radar surveillance aircraft. A military version of the Lockheed L-1049 Super Constellation, it was designed to serve as an airborne early warning system to supplement the Distant Early Warning Line, using two large radomes, a vertical dome above and a horizontal one below the fuselage. EC-121s were also used for intelligence gathering (SIGINT).
Document 13: 711 Squadron (Portugal): The 711 Squadron ""Albatrozes"" ("Esquadra 711") was a flying squadron of the Portuguese Air Force. Its primary mission was Search and Rescue and it has had secondary missions tactical air transport and general air transport in the Azores archipelago. During the time it was active it was the only operational squadron in the Portuguese military to operate both rotary- and fixed-wing aircraft.
Document 14: Sikorsky SH-3 Sea King: The Sikorsky SH-3 Sea King (company designation S-61) is an American twin-engined anti-submarine warfare (ASW) helicopter designed and built by Sikorsky Aircraft. A landmark design, it was the world's first amphibious helicopter and one of the first ASW rotorcraft to use turboshaft engines.
Document 15: Consolidated PBY Catalina: The Consolidated PBY Catalina, also known as the Canso in Canadian service, was an American flying boat, and later an amphibious aircraft of the 1930s and 1940s produced by Consolidated Aircraft. It was one of the most widely used seaplanes of World War II. Catalinas served with every branch of the United States Armed Forces and in the air forces and navies of many other nations.
