Identify anime with submarine under aerial attack [closed]

Question

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

Answer 1

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).

Answer 2

Could it be Marine Boy http://en.wikipedia.org/wiki/Marine_Boy It's from the 60's but is still shown on TV even now. If you look at the episode list there are several involving submarines. I haven't personally seen it myself.

Answer 3

I think it is Super Atragon but its a 90s anime
