I cannot remember the author. I thought the title was We Few, We Happy Few, but I have found nothing close to that.
I believe the book was written between 1965-1975. A moth-balled American aircraft carrier is being sent to the scrapyard, and the navy, laboring under the unpopularity of the Vietnam war, decides to have a film made of a reunion of some of the surviving veterans of the war in the Pacific (hoping for a tale of old-fashioned heroism, I suppose).
The back-story is strongly based on that of the USS Franklin (one of the most damaged ships to survive the Pacific campaign. Much of the book is narrated by the man commissioned to make the film, but most of it is framed as interviews with the veterans.
