These are the voyages of the Hunter I, it's ongoing mission...
...to fill four pages per issue of Gold Key's Voyage to the Bottom of the Sea.
The Hunter I crew had adventures set in the near-future of
the late 1990s-early 2000s, much like then-current films like Green Slime, Wild Wild Planet, and Battle in Outer Space.
With only four pages per issue, there was little character development (or even names) for the crew, but lots of action!
The entire never-reprinted series was written by Dick Wood, and this tale from VttBotS #15 (1969) was illustrated by Jose Delbo, who entered the business in 1965, worked for practically everybody at one point or another, and retired in 1996 with over 800 stories and covers to his credit.
...such as this Silver Age story that reflects the pacifist attitudes of the 18-30 year-olds of the era.
That's how the tale ended in the idealistic '60s.
If they re-did it today, in the far more cynical '10s, one (or both) commanders would have had a strike force ready to attack the second the other side disarmed.
This tale from the Charlton one-shot Outer Space (1968) was illustrated by Pat Boyette.
As to who wrote it, it could have been Boyette (who had already proven himself as a writer with several stories for Charlton's anthologies as well as a couple of issues of Peter Cannon: Thunderbolt), or Joe Gill, who co-created several pacifist heroes including Peacemaker with Boyette, and GunMaster with Dick Giordano!
