Overall, when the carrier is sailing at cruise speed, the noise it emits is not significantly different from a large cargo ship of similar displacement.
Only when the carrier sails at high speed or within close proximity can it be distinguished.
Since Bai Huawei has not made a final decision, the 41st Special Mixed Fleet has been cruising at a standard speed, adopting an anti-submarine formation.
To avoid multiple battleships being attacked by a single submarine, the ships are spaced relatively far apart.
Considering these factors, it is completely believable that the Newland submarine only discovered the 41st Special Mixed Fleet but did not confirm the fleet's identity.
The key is that the identities of the three carriers have not been confirmed!
This inference, instead, puts Bai Huawei in a difficult position.
