Does sonar hurt marine life?
Unfortunately for many whales, dolphins and other marine life, the use of underwater sonar (short for sound navigation and ranging) can lead to injury and even death. These sound waves can travel for hundreds of miles under water, and can retain an intensity of 140 decibels as far as 300 miles from their source.
How much does the US Navy’s Type 054A sonar cost?
The Type 054A’s sonar suite likely costs around $20 million, based on the unit cost of the Royal Navy’s Sonar 2087 and the procurement requirements the U.S. Navy used in 2005 when specifying the characteristics of a new towed sonar array.

What is the purpose of a sonar dome on a ship?
Their purpose is to house electronic equipment used for detection, navigation, and ranging. Sonar domes on Navy surface ships are made of rubber. On submarines, they are made of steel or glass-reinforced plastic (GRP) with a 1/2-inch rubber boot covering the exterior.
The standard US Navy scanning sonar at the end of World War II operated at 18 kHz, using an array of ADP crystals. Desired longer range, however, required use of lower frequencies.
