Submarine question

I recently read TheTerrible Hours by Peter Maas. I was wondering if submarines are still equipped with momsen lungs as a means of emergency escape?

According to the US Navy, no.

I read The Terrible Hours and your link Duckster, too. Did I miss something? No provocation here. I just didn’t see what you’re referring to.

From Duckster’s link (right at the end of the article):

Thanks, Mr B.

That’s the last I trust Evelyn Wood…
