How did the S-2 Tracker compare with the Fairey Gannet, and the P-2 Neptune with the Nimrod?
Short answerNeptune and Nimrod had broadly similar capabilities, though Nimrod was much faster; Tracker and Gannet each held different strengths rather than one being universally superior.
NotesThe P-2 Neptune and Nimrod were broadly similar in capability, with the Nimrod holding a major speed advantage. The S-2 Tracker and Fairey Gannet do not form a simple better-or-worse pair because each was stronger in different parts of the anti-submarine mission. Comparing ASW aircraft requires separate attention to patrol reach, speed, sensors, weapons, and carrier-operating requirements. A single overall ranking would conceal those mission differences.
