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
