Please recommend a science fiction novel from your childhood.

It was a science fiction novel I read in the 1990s. It began with an officer who found a drifting bottle in the sea while on vacation at the beach. It turned out that it was a distress message from the country's most advanced nuclear submarine that had gone missing. Later, when the sunken nuclear submarine was found, aliens were found inside. I can't remember the rest of the plot.
