The invention provides a broadside array assembly for an unmanned underwater vehicle, and the broadside array assembly comprises a broadside array body, the broadside array body comprises a working end face and a connecting end face, and the working end face is provided with a sound sensing unit; the sound insulation layer covers other end surfaces, except the working end surface, of the broadside array body; one end of the vibration isolation device is fixedly connected to the unmanned underwater vehicle body, and the other end of the vibration isolation device penetrates through the sound insulation layer to be fixedly connected with the connecting end face. The vibration isolation and noise reduction device is arranged on the outer side of the broadside array body, transmission of vibration and noise energy to the broadside array sensor can be reduced, the noise of the unmanned underwater vehicle body is reduced, the receiving signal-to-noise ratio of the broadside array is increased, and therefore the det
