Clark Equipment Company in World War Two
Buchanan, MI (Currently Lexington, KY)
1903-Present

This page updated 3-9-2022.

The Clark Equipment Company's true contribution to the winning of World War Two has been overshadowed and masked by one of its smaller production products, the Clark CA-1 Airborne Tractor.  At most, 2,555 of these CA-1 tractors were built during the war, and Clark only built a small portion at its own plant.  This quantity is dwarfed by the 23,000 forklift trucks and Clarktor towing tractors built by Clark in 1945 alone.  Clark also kept the important production lines going at military truck manufacturers by supplying axles and transmissions for many of their vehicles.   During World War Two these products were the primary volume for the US military, even though Clark is better known for the CA-1 Airborne Tractor it designed and built.  Today the CA-1 can be found in military museums.  Its Clarktor four-wheeled aviation tractor is also found at museums.  It is still a working tractor at airports and flying museums.  Forklifts are not found at any of these venues.  Yet after World War Two, the name Clark was synonymous with forklift trucks.  Clark forklifts were predominant in the factories in which the author worked during the manufacturing portion of my career.
 


The Clark Equipment Plant in Buchanan, MI won the Army-Navy "E" Award two times during World War Two.
The Clark Equipment Tructractor Division Plant in Battle Creek, MI won the Army-Navy "E" Award five times during World War Two.


The raising of the E Flag at the Clark Battle Creek plant after it received its second star.  The plant would go on to win two more stars before the war was over.

Clark Equipment Company World War Two Products:  Clarktor 6 tractors, forklift trucks, axle housings for military trucks, transmissions for military trucks, cargo carriers, castings, and CA-1 Airborne Tractors.

The Battle Creek, MI plant had $112,315,000 in major contracts during the war.  The Buchanan, MI plant had $25,476,000 in conatract and the Jackson, MI plant had $61,000 in contracts for forgings.  The total between the three plants was $137,852,000 in major contracts during World War Two.

The Clark Tructractor Company was formed in Battle Creek, MI in 1919 as a division of the Clark Equipment Company, whose main products were tow tractors and forklift trucks.

Clark Equipment Forklift Trucks:  Clark forklifts were important to the American World War Two world-wide logistical effort.  The vast quantity of war material needed to execute the war was shipped from ports in the United States and delivered to military bases, depots, and ports by ships.  Once there, the material needed to be off-loaded and moved.  Designed to work outside, large Clark forklift trucks facilitated this movement.  They were at work at military installations around the world, assisting in getting war material to the front lines.

Medium and Medium/Heavy-Duty Truck Transmissions:  Clark is best known for its forklifts and tow tractors.  Its CA-1 Airborne Tractor has acquired somewhat of a cult status, due to its small size, uniqueness, and the limited quantity produced.  Just as important was Clark's manufacture of 608,333 transmissions for Medium Duty, and Medium-Heavy Duty trucks during World War Two.  Clark produced 571,124 transmissions in its Buchanan, MI plant for two of the most important American trucks, the GMC 2 1/2-ton 6x6 series trucks, and the GMC 2 1/2-ton 6x6 amphibious truck, more commonly known as the DUKW.

General Dwight D. Eisenhower considered both vehicles of paramount importance.

A quote from "The Great Crusade" by General Dwight D. Eisenhower:  "Incidentally, four other  pieces of equipment that most senior officers came to regard as among the most vital to our success in Africa and Europe were the bulldozer, the jeep, the 2 1/2-ton truck and the C-47 airplane."

Another quote from "The Great Crusade" by General Dwight D. Eisenhower, in reference to the Sicily invasion:  "This change resulted from the unforeseen availability of a considerable number of LST's and the quantity production of the "duck", an amphibious vehicle that proved to be one of the most valuable pieces of equipment produced by the United States during the war."

The CA-1 Airborne Tractor:  The number of CA-1s, and which company actually built them during World War Two, is muddled and confusing.  Clark built thirteen C-1 prototypes.  It then went into production as the CA-1 in late 1942.  Delivery of the first of the originally contracted 162 units began in March 1943.  In September 1943, the American Machine and Metals Company (AM&M) in Moline, IL was subcontracted for final assembly of the CA-1 using Clark provided parts.  By the time production of the CA-1 ended, AM&M was making all of the components, except for the transmissions and final drive assemblies.  Clark subcontracted the work because the CA-1 was a small production run, and it needed the production capacity for the thousands of forklifts and tractors needed by the military. 

Two numbers are given as the total number of CA-1s built during World War Two by Clark and its subcontractor, American Machine and Metals Company.  This depends on which historian one uses as a reference.  However, as shown below in the highlighted cells in the table and the photos below the table, Version B is correct.  My research has found two CA-1s with contract dates of 5-25-1944, as predicted by Version B.

Clark and American Machine and Metals Company CA-1 World War Two Production
Contract Contract Date Number Built Version A Number Built Version B Serial Numbers Comments
Prototype C-1     10   The reason that that Version B adds ten C-1 prototypes is because ten were shipped to the 871st Airborne Engineer Battalion at Westover Field, MA.  These units then went with the 871st when it deployed to North Africa.
W-145A-ENG-511 11-10-1942 162 162 CA-1431 to CA143162 This contract was fulfilled by Clark.
W-145A-ENG-614 3-10-1943 30 30 CA143163 to CA143192 This contract may have been fulfilled by Clark.
W-1088-ENG-3460 ? 36 0 CA143193 to CA143228 This contract may have been fulfilled by Clark.
W-1088-ENG-2155 2-8-1943 787 787  CA143229 to CA144016 This contract was probably fulfilled in part, if not completely, by AM&M.
W-145-ENG-2165 2-16-1943 106 106 CA1431016 to CA1431121 This contract was fulfilled by AM&M.
Three more unidentified contracts dated as shown. 5-12-1943, 8-2-1943, 5-25-1944 0 1,460 There is no known published list of serial numbers.

From the data plate of the CA-1 below, on display at Fort Leonard Wood, MO, we know that one of the serial numbers in this group is CA-1441144.  The CA-1 in restoration at the Michigan Military Technical Historical Society in Eastpointe, MI has serial number 1441232.  Both of these Airborne Tractors have contract dates of 5-25-1944.		 Version B is correct, as my research has  found two CA-1 Airborne Tractors with contract dates of 5-25-1944, and serial numbers greater that CA1431121.

 These contracts were fulfilled by AM&M.
Total Production   1,121 2,555    


Two of the thirteen prototype C-1 Airborne Tractors are undergoing testing by Clark technicians.

Author's note:  There are several significant photos below related to the Clark CA-1 Airborne Tractor.  The first two photos are of Serial Number 1433.  This is the third CA-1 to have been built and it is one of the 163 built by Clark.  It is the only one I am aware of that is a Clark-built version.

The photos of the two CA-1 Airborne Tractors shown after Serial Number 1433 prove that Version B, and a total of 2,555, not 1,121 units, were produced during World War Two.

How important were bulldozers to the winning of World War Two?  Below are the thoughts of General Dwight D. Eisenhower and Admiral "Bull" Halsey.

Asked about the weapons used to win the war, Admiral Halsey offered:  "If I had to give credit to the instruments and machines that won us the war in the Pacific, I would rate them in this order:  Submarines first, radar second, planes third, bulldozers fourth."

A quote from "The Great Crusade" by General Dwight D. Eisenhower:  "Incidentally, four other  pieces of equipment that most senior officers came to regard as among the most vital to our success in Africa and Europe were the bulldozer, the jeep, the 2 1/2-ton truck and the C-47 airplane."

Below is a prime example of why both General Eisenhower and Admiral Halsey included the bulldozer in their list of important machines that helped win World War Two.


On March 5, 1944, an airborne assault of thirty American GG-4A gliders landed behind enemy lines in Northern Burma, in a jungle clearing designated "Broadway."  Included in the landing were Clark designed CA-1 tractor/bulldozers.  Using the small bulldozers, army airborne engineers were able to prepare a 5,000 foot long runway within 24 hours, allowing more troops and supplies to come by C-47.  Note the CG-4A glider in the background.


The airstrip has been cleared out to allow the arrival of C-47 cargo aircraft.  General Eisenhower also cited particular aircraft in his list of important pieces of equipment during World War Two.

Clark Equipment Tractors: 


Clarktor tractors await shipment to airfields around the world.


Another contribution of the Clark Equipment Company during World War Two was the Clarktor-6 towing tractor or tug.  Production of the Clarktor-6 began in 1942 and ended in 1966.  Author's photo from the New England Air Museum added 8-9-2018.


This 1943 Clarktor-6 was on display at the 2019 MVPA National Convention in York, PA.  Author's photo added 3-9-2022.


This particular unit was one of six that were assigned to the Lordstown, OH Ordnance Depot.  It was shipped from the Clark plant on September 30, 1943 and served at the Depot until 1953.  It was then purchased by the York, PA airport where it served until 2016.  It is now owned by Mr. Jeremy Dettinger of York, PA.  Author's photo added 3-9-2022.
