Carriers and maritime patrol aircraft reshape naval warfare

Which had the greater impact on naval warfare: aircraft carriers or maritime patrol aircraft?

Carriers have the broader claim, but maritime patrol aircraft are an underappreciated force that both drove submarines underwater and threatened them once submerged.

Aircraft carriers have the broader claim because they changed fleet operations across many missions. The comparison is complicated by carrier air groups that include maritime-patrol and anti-submarine functions. Land-based maritime patrol aircraft have also exerted enormous pressure on submarines. Their influence includes forcing boats below the surface and then helping to find and hunt them while submerged.
