 As a result of the loss of the role of anti-shipping aerial torpedo in modern naval doctrine, true torpedo bomber units no longer exist in modern armed forces.The most common platform for aerial torpedoes today is the ship-borne anti-submarine helicopter, followed by fixed-wing anti-submarine aircraft such as the American P-3 Orion.The caveat to the above are torpedoes delivered by missiles/rocket systems, designed for anti-submarine warfare.
