Which statement correctly describes the MK-105 Magnetic Sweep's power source?

Which statement correctly describes the MK-105 Magnetic Sweep's power source?

• A. It is powered by a solar panel array.
• B. It is powered by a gas turbine generator to run its magnetic sweep gear and waveform output.
• C. It is powered by a hand-crank generator.
• D. It is powered by an on-board diesel engine for propulsion only.

Answer: (B)

The key idea is that the magnetic sweep needs a robust, independent power source capable of delivering sustained electrical power to both the sweep mechanism and its waveform generator. A gas turbine generator provides that level of power in a compact, shipboard package, allowing the MK-105 to operate the magnetic sweep and generate the required waveform output reliably while deployed. Solar panels wouldn’t meet the high and steady power demand in a sea environment, a hand-crank generator isn’t practical for heavy, continuous operation, and having propulsion power only would leave the sweep gear without a dedicated, reliable electrical supply.
