Subsonic speed.
No, traveling at subsonic speed means moving at a speed slower than the speed of sound in air. It does not involve being underwater.
The antonym for subsonic is supersonic.
Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the speed of sound.

A subsonic aircraft does not produce a sonic boom because it is flying at a speed below the speed of sound, which is around 767 mph (1,235 km/h). A sonic boom is created when an object travels at or faster than the speed of sound, causing a sudden build-up of pressure waves that are heard as a loud noise.
The main difference is the speed of the object in relation to the speed of sound. Subsonic refers to speeds slower than the speed of sound, while supersonic refers to speeds faster than the speed of sound. In the case of supersonic speeds, objects are traveling faster than the speed at which sound waves propagate in the medium.
Supersonic

Subsonic flow is commonly used in various engineering applications, such as in the design of aircraft wings, wind turbines, and ventilation systems. Understanding subsonic flow is crucial for optimizing the performance and efficiency of these systems.
subsonic is moving below the speed of sound, supersonic is faster than speed of sound
Subsonic speed refers to speeds below the speed of sound in a medium. In water, the speed of sound is higher than in air, so typical speeds of objects moving through water are considered subsonic.
