AN/SPU-1W is described as which buoyant item?

• A. A sonar transducer housing
• B. A magnetic orange pipe (MOP) filled with Styrofoam for buoyancy.
• C. A radar reflector buoy
• D. A tidal sensor

Answer: (B)

In AMCM gear, certain flotation devices are designed to be simple, highly visible surface buoys that carry or mark underwater sensors. The AN/SPU-1W is described as a buoyant item known as a magnetic orange pipe, or MOP, filled with Styrofoam to provide buoyancy. The bright orange pipe shape makes it easy to spot at sea, and the Styrofoam ensures it floats reliably, even if other components are attached or if minor damage occurs. This combination specifically points to a floating buoy used for marking or supporting magnetometer-related work, rather than a submerged sensor housing, a radar reflector, or a tidal sensor.
