Identify anime with submarine under aerial attack This is an anime movie (OAV?) I saw on a local TV station in the late 80's. It was dubbed in English and here's all that I remember about it:


Set in a futuristic dystopian world.
Hero was a young male with at least one additional male companion.
They find a lost girl and decide to help her.
After sometime they find her father who is the captain of a submarine.
Among the crew is a fat chef who treats the hero and his band to a large feast.
Sometime later, the submarine surfaces, probably to do some kind of maintenance. I remember scuba divers working around the sub.
An enemy jet fighter finds them and starts strafing the submarine, killing several of the divers.
The fat chef attempts to rescue some survivors but gets shot himself.
The movie ends with the sub sinking but the hero and his friends surviving.


EDIT:

It is not any of the following submarine animes:


Submarine Super 99   
Konpeki no Kantai  
Nadia of the Blue Seas
Blue Noah
Blue Submarine No. 6
Thanks to a very diligent redditor I was able to find it.



海底大戦争 愛の20,000マイル
The Great Navy Battle: 20,000 Miles of Love

Released by Tatsonoku in 1981. Apparently it was dubbed by Harmony Gold as Undersea Encounter but was never released for home video, which probably explains why there's almost no trace of it in the web except for a few cover images and brief synopses (mostly in Japanese).
