The International Exhibition Center, I-X Center, was built in 1942 by the federal government. It was one of many plants the government built to gear up manufacturing for the war effort. General Motors’ Fisher division was awarded the contract to manufacture parts of the new B-29 long range bomber. The plant manufactured wing assemblies and engine nacelles which were shipped to other plants for final assembly. The plant also did development work on the X-P75 long range Fighter plane. Work on the plane was suspended because of problems it had in flight tests.The plant employed about 15,000 workers at its peak. Many of these workers lived in nearby Cleveland neighborhoods. A significant number of the workers were women. These women were recruited because there was a shortage of working age men who were drafted into the armed forces. The plant production ran from late 1942 until the war ended in 1945 when it was closed. The government tried to get rid of the plant at the end of the war but had no takers. The plant remained closed until 1950. It was empty for most of this period except for the times it was used as a storage facility.
In 1950, at the start of the Korea war, the the Defense Department awarded a contract to built the M41 Walker Bulldog light tank to the Cadillac division of General Motors. Cadillac picked the former bomber plant as the production site. The plant employed 6,000 people. The M41 was designed to replace the M24 Chaffee a WWll vintage light tank. The Chaffee needed to be replaced because it was no match for the Soviet tanks being used by the North Koreans. The M41 was equipped with a larger gun and an improved range finder. The M41 was produced from 1951 until 1959. It entered service in Korea in 1953. A problem with the the original design of the gun and range finder was the reason it took so long before the tank entered active service. General Motors’ engineers had to redesign the original gun and range finder. The tank was named for General Walter Walker who was killed in a Jeep accident in Korea. General Walker had served under George Patton in WWll and was nicknamed ” Patton’s Bulldog”. The M41 was continually refine over the life of its production. The final versions of the M41 were used during the war in Vietnam.
The plant reopened in 1960 when the Defense Department awarded General Motors a contract to produce several models of Armored Personnel Carriers such as the T-114 pictured below. The plant remained open until 1972. The production switched between General Motors and Chrysler during the life of the contract.
The Defense Department decided to sell the plant after it closed in 1972. General motors was offered the plant but they decided not to go forward with the purchase because they couldn’t agree to terms with the General Services Agency. Brookpark and Cleveland both bid on the plant. The plant was physically located in Brookpark. Brookpark won the auction but was later unable to obtain the financing. The city of Cleveland threatened to take the plant from Brookpark by eminent domain for future airport expansion if the purchase went forward. Ironically, the city had been offered a lease on the plant when it closed in 1942 at $1/yr but turned it down. Eventually the plant was sold to the Park Corporation in 1977. The Park Corporation planned to operate the plant as an exhibition center. The first major exhibitions at the I-X Center were in 1985. The City of Cleveland eventually traded The NASA Research Center with the city of Brookpark for the I-X Center after lengthy bitter negotiations. The city bought the I-X Center from the Park Corporation and leases it to them toda
