Seaplanes are Air Units. They are the only air unit that cannot be produced at an Airport; instead, they are made on Carriers. They are able to attack all units, though they are not able to fire upon submerged submarines. However, they have low ammunition and fuel, and therefore must remain close to rigs, carriers, or airports. To date, they have only appeared in Advance Wars: Days of Ruin.

While seaplanes have very low ammo counts and limited fuel, they are one of the most versatile and tactically flexible units in Days of Ruin, and are ridiculously cost-effective at only 15000 - only 3000 more than a Duster. For only 75% of the cost of a Fighter and 70% or so of a Bomber, you have a much more utilitarian unit that can engage air units or ground units, and can do so very effectively to boot. The fact that they can do satisfactory damage to basically everything, paired with their comparatively low costs, makes them extremely efficient, especially as part of a combined force. Back them up with other units, be they land or sea, and they quickly show their worth.
The fact that you can deploy them on maps that otherwise lack airports means that COs that focus on air combat, such as Tasha and Waylon can still see good use of these units. While less powerful than Fighters or Bombers at their chosen roles, they can do quite a bit of damage, especially with veterancy or when used as CO unit. Putting Tasha in a seaplane, for example, can make for a threatening foe, while one carrying Greyfield or Waylon can be a gigantic pain to shut down.
Seaplanes can become a CO unit by moving the seaplane to the player's HQ.
The first rule of using seaplanes is to always strike first. Seaplanes rarely will have the punch needed to finish off a unit outright, but their opening volley can seriously hurt an opponent and cripple its ability to retaliate. In the case of fighting units that can't fight back at all, such as Tanks, Bombers, and Helicopters, the seaplane fundamentally has free reign to engage and cripple whatever it sees so long as it has the ammo and fuel to keep the pressure on.
That brings us to the second rule of seaplanes: resource management. You need good supply chains to get the most mileage out of them. Use Rigs to fill up their ammo and fuel supplies, and frequently build Temporary Airports to allow resupplies in enemy territory (especially with Greyfield). Back them off to patch them up, since they don't cost much, and while many foes that they can shoot at cannot shoot back, the ones that can will, necessitating such repairs.
The Rubinelle seaplanes resemble A-10 Thunderbolts, while their Lazurian counterparts resemble Sukhoi Su-25 Frogfoots. Both are ground attack aircraft in real life and the former is always deployed from airfields, instead of aircraft carriers, while Su-25K is a very rare sight.
