1. A fire fighting vehicle, comprising:

  • a chassis;

    an engine coupled to the chassis;

    a fluid tank configured to store a fluid;

    a fluid delivery system including;

    a first pump coupled to the fluid tank and configured to pump the fluid therefrom at a first pressure;

    a second pump positioned downstream of and coupled to the first pump in a serial arrangement, the second pump selectively driven by the engine to increase the pressure of the fluid from the first pressure to a second pressure, the second pressure greater than the first pressure;

    a low pressure discharge coupled to the first pump;

    a first high pressure discharge coupled to the second pump; and

    a second high pressure discharge coupled to the second pump; and

    a controller configured to selectively vary at least one of a speed, a power output, and a torque output of the engine based on a mode of operation of at least one of the fire fighting vehicle and the fluid delivery system and thereby provide the fluid to at least one of the first high pressure discharge and the second high pressure discharge at a target discharge pressure.
