Eternal Spring was a fifth generation Smart artificial intelligence. The AI was likely operational from 2530 to 2537.

Eternal Spring was assigned to Onyx and the planetary survey team in the area of Zone 67. After Camp Currahee was established there, Eternal Spring agreed to devote nine percent of its runtime to the Spartan-III project.[1] It got along well with Spartan-051, who was happy for its help, despite It's occasional theatrics.

It assisted in the training of the Spartan-III Alpha Company until It reached the end of its operational lifespan, when It was quickly replaced with another smart A.I., Deep Winter.[2]
