What is the AN/SPU-1W used for?

• A. To sweep waters too shallow for the MK-105
• B. To sweep waters too deep for the MK-105
• C. To deploy acoustic beacons
• D. To measure water temperature

Answer: (A)

In AMCM, the gear chosen for mine clearing depends on water depth. The AN/SPU-1W is the shallow-water sweep unit designed for environments where the MK-105 cannot operate because the water is too shallow. It provides a lighter, lower-profile sweep that can be towed safely in very shallow water near shore or over shoals, allowing the aircraft to clear a lane without the risk of bottom interference. The other options don’t fit because deploying acoustic beacons, measuring water temperature, or sweeping deeper waters aren’t the functions of this unit.
