PQ 17's protection was layered rather than one undifferentiated escort formation. The distant force contained major British and American units, including a battleship and carrier screen with destroyers from both navies. The cruiser covering force was also mixed, while the close escort was British and included the ships directly responsible for the convoy. That structure places a remembered American-destroyer response to aircraft more plausibly with the covering or distant force than inside the close escort. The exact incident remains unresolved, but the order of battle gives a clear picture of coalition command and graduated protection around an Arctic convoy.
