June 25, 1950

Approximately 4 a.m. (Korean Standard Time) on a rainy Sunday morning, the Democratic People's Army artillery and mortars open fire on Republic of Korea Army positions south of the 38th parallel, the line serving as the border between the two countries. at 11:00 a.m. North Korea announced a a formal "Declaration of War" which is now remembered as the "Korean War". The U. S. President , Harry S. Truman was notified of the invasion and returned from his home in Independence, Missouri to Washington, D. C.

JPG did not stay on "Standby" for long. In February 1949, inquiries were initiated to determine the feasibility of reactivating the testing center. In the next 12 months, employees were hired for proof testing ammunition. in 1951 and 1952, new construction included barricades for the for the East, West, rocket assembly plants, and an assembly plant group for major caliber positions. In January 1952, JPG employed 813 employees; by Junw the figure climbed to 1170, reaching a peak of 1375 employees by the end of 1952. In 1952, the number of rounds fired reached 120,000. Employment levels made a jump in 1953, rising to a level of 1774 in August of that year, just before the end of the "Korean Conflict".

The "Korean War" precipitated a second wave of building at the installation. For the most part these consisted of additional test firing and storage facilities, but with improvements to the infrastructure as well.
