Which device is used to sweep waters too shallow for the MK-105?

• A. MK-105 Magnetic Sweep
• B. MK-106 Magnetic/Acoustic Sweep
• C. MK-2(G)
• D. AN/SPU-1W

Answer: (D)

In shallow-water environments, the equipment used for mine sweep must be compact and able to operate without risking snagging on the seabed or shore features. The MK-105 magnetic sweep is a deeper-water system that generates a magnetic field to trigger magnetic mines, but its tow geometry and clearance requirements make it unsuitable when the water is too shallow. The AN/SPU-1W is designed for shallow-water operations, providing a sweep capability that can be deployed in nearshore conditions where the MK-105 can’t operate. It matches the need to cover shallow zones without the depth and clearance constraints of the deeper-towed magnetic gear. The other options either serve different roles (such as combined magnetic and acoustic signatures) or are not intended for the shallow-water mission, so they don’t fit as the best answer for waters too shallow for the MK-105.
