The Kingfisher is a versatile SSTO vehicle designed for going from literally sea level on Kerbin all the way to LKO. A novel hydrofoil design allows the aircraft to pick up substantial speed in the water, while conventional landing gear also allows for runway landings.

Instructions for Use

From Land

Pitch off the runway at 60m/s.
Fly as normal.

From water

Deploy the forward and rear hydrofoils using action groups 1 and 2 and begin accelerating.
At 30m/s, nose up slightly to raise the nose up out of the water on the forward hydrofoils. Continue accelerating.
At 55m/s, pitch up dramatically to leave the water.
Transition RAPIER mode at 27km.
Shut off RAPIERs when apoapsis reaches 75km, continue on nuclear power


Fly a shallow reentry with a periapsis set at 24km. From a 75km orbit, a peripasis over the peninsula west of the Kerbal Space Center will provide reasonably reliable landings over the KSC.
Keep pitch angle within 10 degrees of prograde throughout reentry. Deploy the airbrakes as needed.
At 25km, deploy the airbrakes and set SAS to prograde. Follow this course until subsonic.
Once subsonic, retract airbrakes and land as normal.

Built in the SPH in KSP version 1.12.4.
