sanshikidan were basically fragmentation rounds, which works great on soft targets. They used sanshiki rounds on airfield bombardment because most of them are soft targets, (runway, aircraft and ground structure are generally unarmored on these frontline airfield compare to heavy ships) where shrapnel worked best.

AP rounds are better at making holes on ships (hopefully below waterline) to encourage sinking.
