The current Prime Power Production Specialist training program evolved from the Nuclear Power training program that was established in 1958 to train and qualify members of the Army, Navy, and Air Force as nuclear reactor operators and technicians. As military power requirements changed, so did the training program. In 1977, the Nuclear Power program was phased out and replaced by the Non-tactical Generator program. In 1985, the name was changed to the Prime Power Production Specialist Course.

The Prime Power Production Specialist Course, with Additional Skill Identifier (ASI), is a year-long program of instruction designed to train selected applicants to deploy, install, operate, and maintain the Army's Prime Power Program (P3) power generation and distribution assets in support of theater commanders under the provisions of AR 700-128. Students must successfully complete a demanding two-phase training course in order to qualify in the MOS 12P, Prime Power Production Specialist. Upon satisfactory completion of the MOS 12P course, each student is assigned to one of the three Additional Skill Identifier courses of instruction that qualifies the graduate as a Prime Power Production Instrumentation Specialist (ASI-E5); Prime Power Production Mechanical Specialist (ASI-S2); or as a Prime Power Production Electrical Specialist (ASI-S3).

Prime Power graduates work in many challenging and rewarding assignments worldwide. In wartime, Army personnel are responsible for supporting Prime Power program missions. In peacetime, skills are maintained through training exercises, emergency deployments for disaster relief efforts, and special purpose deployments for electrical power requirements in operations other than war. We also provide technical assistance missions in support of the Directors of Public Works (DPW) throughout the United States and overseas.

The Prime Power soldiers have established a long tradition of excellence, and have earned a well-deserved reputation of upholding the highest standards of the Corps of Engineers. "Essayons" truly describes, both past and present, the spirit and actions of Prime Power Soldiers.
