British destroyer torpedo specialists trained to aim at ships already burning during night actions. A fire was not a fixed point: it flickered, changed shape, and moved with the target, so estimating the firing solution demanded specific practice. The Royal Navy is identified as the only navy known to have rehearsed this method during the interwar period. The practice continued during the Second World War and illustrates how British night-fighting doctrine extended beyond gunfire into torpedo control.
