Where military seaplanes still offer value

Is there still a military role for seaplanes?

Yes, especially for island resupply, dispersed operations, and selected anti-submarine missions.

Seaplanes can resupply islands that lack a conventional runway. They can also support selected anti-submarine missions and dispersed operations across an ocean area. Water offers many potential operating locations compared with a small number of fixed airfields. That dispersion makes it difficult for an opponent to identify and close every place from which the aircraft might work.
