Unbeknownst to the Prometheus Crew the super villain Hypnotia snuck aboard and planted a Bio-Conversion Device. The captain noticed strange readings and found the hidden woman. She incapacitated them and covered the entire crew in a strange substance. She then used a laser to cut a hole in the hull and sank the sub.
The United States found out that the readings they noticed were in fact a submarine and initiated Operation Prometheus. Admiral Harold Younger tasked Tony Stark and James Rhodes with finding the sub. They believed that the sub contained something that was possibly disastrous to mankind.
Iron Man found the submarine but Mandarin and MODOK were watching and he was attacked by Blacklash, Dreadknight, Whirlwind, and Grey Gargoyle. Luckily Rhodes and Force Works were watching and Century transported them to the sub to help Iron Man. However, Mandarin sent Fin Fang Foom and the heroes were defeated.
The final fate of the Prometheus is unknown.
The submarine was named after the ancient Greek myth of Prometheus, who stole fire from the gods and gave it to man. Prometheus was credited, and blamed for, playing a pivotal role in the early history of humankind, similar to the sub's pivotal role in Iron Man's and Mandarin's history.
