Why a helicopter hangar was not the decisive ASW gap

An encounter with a Flight III Los Angeles-class submarine tests how much an embarked helicopter matters to frigate anti-submarine warfare.

Question

Did the lack of a helicopter hangar explain why the frigate failed to detect a Flight III Los Angeles-class submarine?

Short answer

No. The more important mismatch was between older sonar and signal-analysis systems and a very quiet submarine operating as a hunter.

Notes

The answer places more weight on the frigate's aging sonar and computing systems than on its lack of a helicopter hangar. A Flight III Los Angeles-class submarine is still an exceptionally quiet target when operating in hunting mode. Astute, Seawolf, and Virginia are described as quieter, but that comparison does not make the older American submarine easy to detect. The encounter illustrates why the quality of sensors and signal analysis matters alongside the availability of embarked aviation.
