The F1M, designated as Type 0 Observation Plane (零式水上観測機), replaced the E8N2 and served as a scout for battleships. It also performed various other tasks, such as escorting convoys, bombing targets, maritime patrol, rescue, transport, and anti-shipping strike.

The F1M2 has been in the game since the start of the Open Beta Test prior to Update 1.27. Although it is classified as a bomber, it only carries 2 x 60 kg bombs and has a high-altitude bomber spawn, which limits its effectiveness in that role. The best approach is to spawn at the airfield and compete with fellow biplanes as a fighter, a role the F1M2 performs better at, surprising unsuspecting enemies with its versatility.
