It makes sense to an extent since the Kaiboukan were designed to engage in the types of operations that expeditions 4, 5, and 9 anre named after. Maybe there are more missions that can get overrided by either fleet composition and/or equipment considering the objectives of the missions and accounting for historical counterpart expeditions.

Expedition 4: Anti-submarine patrol mission ( 対潜警戒任務 "Taisen keikai ninmu").

Expedition 5: Maritime Escort mission (海上護衛任務 "Kaijou goei ninmu").

Expedition 9: Tanker Escort mission ( タンカー護衛任務  "Tankaa goei ninmu").
