Would foreknowledge change treaty allowances and the timing of radar or ASDIC development?
Short answerThe priority would be operational ASDIC, convoys, and mass escort production years earlier, with sensitive equipment installed after foreign-built hulls arrived.
NotesModern foreknowledge would make early ASDIC deployment a priority in 1915. Convoys and detection pickets would accompany an enlarged sloop programme, with the existing Flower-class order at least doubled. American and Canadian yards could add capacity, and Japanese construction is also accepted despite a concern about sharing anti-submarine ideas. Hulls could be ordered with space for equipment that would be fitted after delivery. The foreign builder would receive the required hull specification without needing the complete detector installation. The proposed advantage depends on combining detection, escort numbers, and convoy organisation.
