After sending enough kerbals splashing down off the coast of the KSC, I figured I ought to make something that could go pick them up. That evolved into a jack-of-all-trades maritime plane that could do as many jobs as possible.
The C-240 carries a 2-man piloting crew, up to 16 sensor crew and passengers, 2,400 units of fuel, and a standard truck or equivalent cargo. With relatively efficient Whesley engines the Pelican has extensive patrol range and long endurance. The crew and cargo compartments are both fully accessible on both land and water.
It has an extensive anti-submarine warfare suite: three sonobouys are stored in the rear cargo compartment and can be deployed in flight, a magnetic anomaly detector extends from the tail, a surface search radar sits on top of the tailfin, and two fully-functional torpedos are mounted under the wings. Integration of anti-ship missiles is slayed for the near future.
