The SUPERSOLDIER program was part of the U.S. military's attempt to replicate a serum developed during WWII and used on an individual known as "Captain America" (real name, Steve Rogers), to create an army of super-powered soldiers. The serum’s effects conferred an enhancement to the human body’s natural strength, agility, and endurance.
Nathaniel Essex, upon his departure from the school, was approached by the United States Army Medical Research Institute of Infectious Diseases (USAMRIID) to work on the program. He made a deal that he would do so, but from a civilian base, Muir Island Research Facility. Following his abrupt departure from Muir, nothing is known about his continuing connection with the program. It was Essex's involvement with the government and departure from the school that prompted Chester Whelan to reactivate Gambit.
The Phase 2 history of the Super Soldier program is less cloaked in mystery. Created by Dr. Abraham Erskine, it was tested on only one subject - Steve Rogers, who later became known as Captain America - before Dr. Erskine's death at the hands of HYDRA agents who infiltrated the laboratory. With Erskine's death and Captain America's later disappearance, the secret to the serum was lost, but that did not prevent various agencies from trying to develop their own versions - the Red Room, Project Winter Soldier - even to current day.
Captain America himself was revived in 2014 and is now part of SHIELD's superhuman response team, The Avengers.
