Oldsmobile in World War Two
 Lansing, MI
Rest in Peace

Updated 4-11-2017.

I drew up in Lansing, MI where in my childhood and early adulthood was dominated by the presence of Oldsmobile in the city.  Oldsmobile was the economic engine that drove the economy, and provided the jobs for many of the fathers of my school friends.  Oldsmobile was important to my family, even though my father worked for the nearby Fisher Body Division of General Motors Oldsmobile was still important to our family, as my father's plants produced the automobile bodies for the Olds.  Indirectly Oldsmobile dominated my life and my family's as I grew up.  I have memories of new Olds mobiles being driven past my grade school to the nearby trucking companies that would put them on trailers and deliver them to dealers around the country.  The Oldsmobile plant was just a half a mile down the road from my school.

Oldsmobile in 1905 looking south east from Division Street and Olds Ave.  In 1905 Olds Avenue was Issac Street.

The Olds Administration Building that served the division during WWII. It was replaced by a more modern structure in the 1960/70s.

Oldsmobile in 1950 looking west.  The old administration building pictured above can be seen in the lower right hand corner of the complex.  I grew up in the neighborhood to the south of the Grand River that bordered Oldsmobile.  I fished and played in Moores Park on the south bank of the river while growing up in Lansing.  Photo added 11-16-2015.

This post 1975 photo looking NW in Lansing show the Olds Complex at its peak before being dismantled after 2004.  In the back ground one can see the Fisher Body / Olds Forge / Olds Jet Plants.  A new administration building can be seen in the location of the former one show above.  The new administration building still exists today.  In the foreground is the empty field is where REO used to be.

The Oldsmobile complex shown in the previous two photos was replaced by the GM Grand River Assembly Plant.  Several of the older buildings from the Oldsmobile era still appear to stand.  The heat exchangers along the Grand River in the foreground were there when I fished on the opposite side of the river when growing up in Lansing.  The plant assembles the Cadillac CTV and ATV, and the Chevrolet Camaro.

Oldsmobile Plant Number Two in 1945 looking east with Lansing Fisher Body behind it and up in the right hand corner is the newly completed JW Sexton High School that I would attend 20 years later.  Visible on the south end is the gymnasium.  The Fisher Body plant's power housed supplied steam to both plants.  In the distance through the smoke haze is downtown Lansing.  The capital dome is not visible in this photo.

Today Oldsmobile is gone, and most of the plants shown in the photos above have been razed.  Lansing and the surrounding area still has two GM Assembly plants building the Cadillac CTS and ATS, Chevrolet Camaro and Traverse, and Buick Enclave.  But it is not the same for those of who grew up in Lansing under the protective shadow of Oldsmobile.  Oldsmobile then had its headquarters and engineering staff along with its own forge and engine plants in Lansing.  Engineering advances were developed in Lansing, not at the GM Warren, MI Technical Center, as they are today.  The aura of an GM auto town with its own auto division is no longer present.

This 1903 Olds Curved Dash was first introduced in 1901, and is considered to be the first mass produced automobile.  It was was actually built by Olds in Detroit before a fire destroyed the factory, and Olds moved back to Lansing.  Author's Photo from the Gilmore Car Museum in Hickory Corners, MI.

This 1910 Oldsmobile was the first motorized fire truck in the state of Indiana.  Author's Photo from the Terre Haute Fire and Police Museum, Terre Haute, IN

On display at the RE Olds Museum in Lansing, MI are many of the engine technologies developed and built in Lansing.  In the center of the display is the first Olds High Compression "Rocket" V-8 engine, the first of its type in the industry.  Olds developed many other automotive innovations in Lansing.  Author's photo added 4-12-2017..

Little did I know of Oldsmobile's huge contribution to the winning of World War Two until I started my research on the subject.  Lansing Oldsmobile built "Firepower" in the form of 125,527 cannon ranging in size from 20mm to 76mm,and 20,418,600 artillery shells ranging in size from 75mm up to 155mm.  Oldsmobile's two borrowed GM plants in Janesville, WI, and Kansas City produced produced another 24,919,390 shells ranging in size from 75mm to 105mm.  Total shells produced by all Olds operated plants was 45,338,190.

This was display of Olds military products in the plant from the Second World War.

The original and extremely rare Army-Navy "E" award flag that Lansing Oldsmobile won on August 10, 1942.  Lansing Olds then won three stars as can be seen on the flag on February 6, 1943, September 25, 1943, June 3, 1944.  The "E" Award was the most coveted award given to companies by the Army and Navy for outstanding work in producing war material.  This flag is very rare. and is one of only four original Army-Navy "E" award flags still in existence in museums today.  Author's photo taken at the RE Olds Museum.

This plaque detailing the Lansing Oldsmobile "E" Awards is also on display at the RE Olds Museum.  Author's photo added 4-1-2017.

Oldsmobile Janesville won its first Army-Navy "E" Award in December of 1943.  It won two more for a total of three.
Oldsmobile Kansas City won the Army-Navy "E" award four times.

This M4A3 Sherman tank built in the Fisher Body Tank Arsenal in Grand Blanc, MI in March 1944 has an Olds built 75mm M3 cannon and is on display in downtown Bastogne, Belgium.  Olds was one of four companies building the cannon during WWII and would have supplied M4 tank production at not only the sister GM plant in Grand Blanc, but the Chrysler Tank Arsenal in Warren, MI. Author's photo added 10-31-2015.

This Fisher Body Grand Blanc, MI built M4A2 Sherman tank and its Oldsmobile built M3 75mm main gun landed with Canadian tanks forces at Normandy, and survived the entire European campaign.  Holy Roller is on display at a park in London, ONT.  Author's photo.

The Cadillac designed and built M24 Chaffee light tank came with the one of the 5,129 M6 75mm cannons Oldsmobile produced during World War Two.  The M6 version was a developed for the Chaffee tank and came with a thinner barrel wall and different recoil mechanism than the M3 cannon used on the M4 Sherman.  The 75mm gave the tank crews in the M24 increased firepower over the previous 37mm cannon they had in the M5 series light tanks.  Not only did Cadillac build the M24, but Massey-Harris also contributed to the 4,731 built.  Author's photo taken at the tank park at the First Division Museum in Wheaton, IL added 10-31-2015. 

This Oldsmobile ad is touting the attributes of the Hydra-Matic transmission supplied before the war to Olds by Detroit Transmission Division of GM.  The Hydra-Matic transmission was exclusive Cadillac and Oldsmobile and is  one of its marketing features Olds wanted to advertise for sales after the war.  Customers would not be purchasing the 76mm cannon so it was more of a side note in this ad.

The Oldsmobile built M7 3 inch cannon was used on Fisher Body built M10 and Ford built M10A tank destroyers like this Fisher M10 at the Patton Museum at Fort Knox, KY.  Olds also manufactured 1,026,120 shells in Lansing for the weapon and Olds Janesville, WI produced 4,917,115 shells and shot for the 3 inch gun.  The Kansas City Olds Plant produced another 1,122,287 shells for it.

Elco PT-579 on patrol in the Philippines during the last two months of WWII.  Note the Olds 37mm aircraft cannon that now resides on bow of the boat.  Old's cannons like this were scavenged from derelict P-39s, and mounted on the front deck to give PT boats more fire power.  This was common to many PT boast during the war and the weapon found a use it was never intended for.  Photo added 11-10-2015.



Oldsmobile built 37mm feed mechanisms like this one in a Bell P-63.  Author's photo.


Seen here is B-25H "Barbie III" at the Urbana, OH airport in 2010.  The H model B-25 carried the Olds 75mm M3 cannon.  Author's photo added 10-31-2015.

One can see the barrel of the Olds built M3 cannon in the lower left of the nose of the B-25.  Of the 25 B-25s that are still flying, 'Barbie III" is the only one in the cannon configuration.  Author's photo added 10-31-2015.

Originally the Olds 75mm cannon was hand loaded which allowed for three or four shots per minute.  Later a automatic feed system was developed that utilized the T9E1 75mm cannon with an automatic feed system, which was not produced by Oldsmobile.


A Lockheed P-38 as shown in the ad above.

The 20mm cannon is the one on the left.  The others are .50 machine guns that could have also been manufactured by a GM Division.

The engines were supplied by the Allison Division in Indianapolis, IN.
