Enemy submarines are harder to detect, but next-gen sonobuoys search them out

[Sponsored] As adversary submarines grow quieter and more elusive, the Navy turns to a new generation of more capable, connected, and open sonobuoys.

Why this matters
Why now

Adversary submarines are increasingly quiet and numerous, particularly from China and Russia, making advanced detection capabilities a critical and urgent need for naval powers.

Why it’s important

This development highlights the ongoing arms race in undersea warfare and the critical need for advanced technological solutions to maintain naval superiority and protect maritime interests.

What changes

The focus shifts towards more sophisticated, connected, and open-architecture sonobuoys, indicating a move beyond traditional ASW tactics to integrate advanced sensor networks and data processing.
