from how far away can you hear a torpedo
The distance at which a torpedo can be heard depends on various factors, including:
1. Type of torpedo: Different torpedoes have varying levels of noise emission. Modern torpedoes are designed to be quieter than older models.
2. Speed: A torpedo’s speed affects the noise it produces. Faster torpedoes tend to be louder.
3. Water conditions: The clarity and temperature of the water can impact sound propagation. In general, sound travels farther in warmer and clearer water.
4. Background noise: The presence of other noise sources, such as ships or marine life, can mask the sound of a torpedo.
That being said, here are some rough estimates of the distance at which a torpedo can be heard:
* A World War II-era torpedo: 10-20 kilometers (6-12 miles) away
* A modern torpedo (e.g., the US Navy’s Mk 48): 5-10 kilometers (3-6 miles) away
* A high-speed torpedo (e.g., the Russian Navy’s VA-111 Shkval): 1-5 kilometers (0.6-3 miles) away
Keep in mind that these estimates are rough and based on various assumptions. In reality, the actual distance at which a torpedo can be heard will depend on the specific circumstances.
It’s also worth noting that modern submarines and surface ships often use passive sonar systems to detect torpedoes, which can detect the sound of a torpedo at much greater distances than the human ear. These systems can detect the faint sounds of a torpedo’s propeller or the noise generated by its movement through the water, allowing for earlier detection and response.
