yes, exactly, salt water is VERY VERY bad Your main engines are gimballed for guidance, that mass cost is already paid

- baybal2 7y agoI hardly can imagine why. Their rockets are carbon fibre, aluminum-lithium, and steel alloys with such overkill corrosion rating that they should stand strong acids, not simple seawater. And mass cost of hydraulics for propulsive landing != hydraulics for regular gimbal steering. Those should be very different in their power and mass. Not only they have to steer the gimbal much faster and harder, but also aerodynamic elements on the rocket, fuel throttle, and those legs they land on.
