Cadillac Motor Car Division of General Motors in World War Two
Detroit, MI
1902-Current
This page updated on 1-20-2022.


The Cadillac Motor Car Company originally began as Henry Ford's second attempt to start a car company.  However, when investors hired Henry Leland to come in as a consultant, Ford left the company.  Under Leland's leadership, it became Cadillac.   This 1903 Cadillac is on display at the Gilmore Car Museum.  Author's Photo.

Cadillac Motor Car in World War One:  Cadillac built 2,500 Model 57s for the U.S. Army during World War One.  Of the 2,500, 2,100 were sent to Europe for use by officers.  The one shown below was giving to the Louisiana National Guard after the war and was used until the early 1930s.  It is now on display at the Jackson Barracks Museum in New Orleans, LA.

Cadillac Motor Car Division World War Two Production Statistics:  (1,470) M5 Stuart tanks, (3,530) M5A1 Stuart tanks, (1,778) M8 75mm howitzer motor carriages, (3,592) M24 Chaffee tanks, (300) M19 Twin 40mm anti-aircraft carriages, (175) different parts for the Allison V-1710 aircraft engine including crankshafts, camshafts, connecting rods and piston pins, supercharger rotator vanes and gear reduction assemblies, at least (12,880) V-8 engines to other manufacturers of armored vehicles. 

Author's Note:  Some sources credit the M5 and M5A1 Stuart tanks built by the Southern California Division of General Motors at South Gate, CA to the Cadillac Division of GM.  The Southern California Division of GM was its own entity within the GM corporate family.  For more information see my Southern California's War Division webpage.  The Southern California Division built 354 M5 and 1,196 M5A1 light Stuart tanks.  These have Cadillac data plates on them as Army Ordnance considered Cadillac as the prime contractor.  Combined the two GM divisions built (1,824) M5s and 4,726 M5A1 Stuart tanks.

There were another 2,074 M5A1 Stuart tanks built by Massey-Harris and American Car and Foundry.  Cadillac supplied the 4,148 V-8 engines for these.  Cadillac also supplied 500 engines for the 250 Massey-Harris built M5s.  It also furnished 2,278 V-8 engines to Massey-Harris for the 1,139 M24 Chaffees it built.  For the Borg-Warner and Gramm-Paige-built LVT(3), it supplied 5,924 V-8 engines.  It also supplied 60 engines to GMC for its construction of the T18E2 Boarhound Armored Car.

Cadillac was located at an original 47 acres complex at Clark and Scotten Streets in Detroit and was known as the Clark Street Plant.  Construction began in 1919 on the four story 2.7 million square foot assembly and administration buildings.  Construction at the complex was completed in 1927 with a foundry added in 1923.  When complete, it was considered to be the world's most modern car plant.  Bodies were supplied by the Fleetwood Plant of Fisher Body, which was three miles away.  The complex was closed in March of 1994.  Today all of the buildings are gone.


Cadillac won the Army-Navy "E" award on January 13, 1943.  It later added three stars for a total of four awards.

This 1938 Series 75 Cadillac Limousine has the distinction of being the car that General George S. Patton was in when he had his fatal accident.  Built in Detroit and then sent to France before the start of hostilities, it was used by the Gestapo during the occupation of France.  Liberated in 1945 by American troops of the 5th Army , it was presented to General Patton to use as his staff car.  Today it can be seen at the Patton Museum at Fort Knox, KY.  Author's photo.


After the accident, the vehicle was rebuilt using a Cadillac V-8 engine from a M24 tank to replace the original damaged power plant.  After continued use as a staff car in Europe, it came to the Patton Museum in 1951.  Author's photo.


This 1930 Cadillac V-16 engine was a predecessor to the V-8 engine that would power the M5 Stuart Series and M26 Chaffee tanks in World War Two.  It displaced 452 cubic inches and produced 165 hp.  Author's photo from the Gilmore Car Museum.

Here is a General Motors Allison V-1710 V-12 Aircraft engine that contained up to 175 parts manufactured by Cadillac in Detroit.  Cadillac began supplying parts for the Allison engine in 1939.  Author's photo at the Museum of the United States Air Force.


This T18E2 GMC built Boarhound was powered by two Cadillac V-8 engines and was photographed at the GM Proving Grounds on January 19, 1943.


Chevrolet began development on the M38 armored car in 1944 as a replacement for the M8 Greyhound.  Production did not get started until March 1945 on the new armored car, and only five pilot models were built due to the end of the war in Europe.  The M38 was powered by a Cadillac V-8 engine mated to a Detroit Transmission Hydra-Matic transmission.  Photo added 1-8-2020.


This photo at the Museum of the United States Air Force has an Allison engine in front of a Lockheed P-38.  Author's photo.


This shows the entire P-39 drive train with General Motors Divisions' components.  On the left is the Allison V-1710 engine, then the Oldsmobile built 37mm cannon, the Cadillac gear reduction unit, and then the Aeroproducts propeller.  The engine was behind the pilot and the driveshaft went between the pilot's legs, allowing the cannon to fire out center hub of the prop.  Author's photo from the National Museum of the United States Air Force.


This gives a closer look at the cannon, Cadillac gear reduction unit and prop.  Author's Photo.


Note that the cannon fires through the center hub of the Aeroproducts propeller but does not go through the center of the gear reduction unit.  Also, the brass input propeller shaft is off centered.  Author's Photo.

On the left hand side of the ad is an M5/M5A1 tank.  On the right side is an M8 3-inch howitzer motor carriage.


This ad implies that Cadillac built its own Hydra-Matic transmissions, which is incorrect.  They were built by the Detroit Transmission Division.  See my Detroit Transmission page for more information.


This very colorful World War Two ad shows a GM Allison powered Lockheed P-38 wreaking havoc on Japan.  Cadillac made 175 different parts for the Allison aircraft engine.

Cadillac Military Products after World War Two

The following items were produced at the former Fisher Body Aircraft plant #2 at the Cleveland, OH airport.  This was a US government built and owned building and returned to the control of the government after World War Two.  When the Korean War broke out, the plant was opened back up and became the Cleveland Tank Arsenal under Cadillac management.  Cadillac was back in the business of making light tanks!

All of the following photos except for the M108 were taken at the 2017 MVPA Convention in Cleveland, OH. 


Starting in mid-1951 until mid-1954, Cadillac produced 3,729 Walker Bulldogs.  Author's Photo added 4-3-2020.

M56 "Scorpion" anti-tank guns were also produced by Cadillac at the Cleveland tank arsenal from 1953 to 1959.  Armed with a 90mm gun, the M56s were used in Vietnam as point defense and as artillery.  There were 150 of the Scorpions built.  Author's Photo added 4-3-2020.


Cadillac started building M42 and M42A1s Dusters in 1953.  The twin 40mm tracked anti-aircraft gun carriage was based on the chassis of the M41.  Cadillac built approximately 3,700 of the Dusters.  Author's Photo added 4-3-2020.
