AM General · The Humvee Works on McKinley Highway

AM General is Mishawaka's defining industrial fact. The company that builds the Humvee — and now the Joint Light Tactical Vehicle that succeeds it — has run its assembly plants on the city's east side, along McKinley Highway, for more than half a century: first in a borrowed building that had made components for Studebaker, where it built truck beds and then transit buses in the 1970s, and from 1984 in the plant remade for the Humvee, the vehicle that made the works famous on every battlefield and television screen of the 1990s. For one decade the Mishawaka plants also built the most conspicuous civilian vehicles in America: the Hummer H1 in the military plant and, from 2002, the H2 in a second plant built for it under General Motors' ownership of the Hummer brand. The brand died in 2010; the military line never stopped. What followed at the commercial plant — a wheelchair-accessible van, a Mercedes-Benz built under contract, and two electric-vehicle ventures that between them produced one start-up run of vans — is told here at exactly the strength the record carries it, announced kept separate from accomplished. The company itself descends from the government-products business of Kaiser-Jeep, taken into American Motors in 1970 and incorporated as AM General in 1971; its headquarters sits in South Bend, and that side of the company prints as boundary here. What follows is the whole arc at the size the Mishawaka record carries: the descent, the building, the buses, the Humvee, the GM chapter whole, the after-GM course, the contracts, the workforce, and the works today.

The descent: from Willys and Kaiser to the government-products business

1953 – 1970

The Kaiser purchase: AM General's line begins with the Jeep. Kaiser Industries bought the assets of Willys Motors — the Toledo maker of the wartime Jeep — on 23 March 1953, and the firm that resulted, carried first as…

AM General is formed

1969 – 1971

The sale announced: On 2 December 1969, at the Detroit Hilton, AMC chairman Roy D. Chapin Jr. announced the agreement to buy the Kaiser Jeep Corporation from Kaiser Industries. American Motors stockholders approved overwhelmingly…

The Mishawaka building before the Humvee

to 1974

A Rockwell building: The Mishawaka plant is older than the company that made it famous, and older than the vehicle it is known for. On the specialist record — Military Trader's company-sourced photographic history of AM General …

The bus years: the Metropolitan

1974 – 1979

A licensed design: AM General's diversification into transit buses rested on someone else's coach. Flyer Industries of Winnipeg, Manitoba — Western Flyer — had designed its D700 transit bus for the Canadian market; AM General…

The Humvee is designed

1979 – 1983

The requirement: In 1979 the Army set out to replace two aging light vehicles — the M151 jeep and the M561 Gama Goat — with a single high-mobility multipurpose wheeled vehicle: a 1.25-ton truck family in several configurations…

The 1983 contract — and the government's own warning

1983 – 1984

The award: On 22 March 1983 the Army awarded AM General the production contract: $1.2 billion, multiyear, for 55,000 vehicles in five basic models and fifteen configurations over five years, 39,000 of them for the Army itself…

The plant remade for the Humvee

1984 – 1985

The two tellings: What happened on McKinley Highway in 1984 is told two ways, and both are printed. The standard reference works say AM General built a factory for the Humvee: the encyclopedia history records that in 1984 the…

The Humvee at war: Panama, the Gulf, Somalia

1989 – 1995

First combat: The HMMWV first saw combat in Operation Just Cause, the invasion of Panama, in 1989. It had been designed as a behind-the-lines vehicle — personnel and light cargo transport, in the reference history's plain…

The civilian Hummer

1992 – 1999

The campaign for a civilian version: The civilian Hummer exists because the Gulf War put the vehicle on television and because one viewer would not take no for an answer. Arnold Schwarzenegger saw an Army convoy while filming…

Ownership: the LTV and Renco years

1983 – 1992

Sold by AMC: American Motors, weakening through the early 1980s, sold the subsidiary that had so often carried its results. In September 1983 — the dating is the Government Accountability Office's, from its report on the Humvee…

Iraq and the armor crisis

1996 – 2007

A vehicle used past its design: The Humvee went to Iraq in 2003 as it had been designed — a light, unarmored truck for work behind the front line — and the war it met was an insurgency, in which there was no behind-the-lines. The…

The GM chapter I: General Motors buys the brand

1999

The announcement: In June 1999 General Motors and AM General announced their intention: GM would take the Hummer name into its brand empire, and AM General would build the vehicles. The agreements were entered on 21 December…

The GM chapter II: the H2 and its own plant

2002 – 2009

A second plant on McKinley: The 1999 agreements obliged AM General to build a new facility for the H2, and it rose beside the military plant: the AM General Commercial Assembly Plant, at 12900 McKinley Highway. Its size is…

The GM chapter III: the H1 under General Motors

2000 – 2006

The original, continued: GM's ownership of the brand changed the H1's name and its marketing, not its manufacture: the vehicle went on being built in the military plant at Mishawaka, beside the Humvees, on AM General's line. The…

The GM chapter IV: the H1 ends

2006

The decision: The decision to end the H1 was made on 9 May 2006 and announced on 12 May 2006; production ended in June 2006. The two stated reasons are printed as the record gives them, because together they describe exactly what…

The H3 boundary: the Hummer Mishawaka never built

2005 – 2010

The boundary printed plainly: The third Hummer was not a Mishawaka vehicle in any part. The H3 was General Motors' own design on GM's own midsize platform, and it was built by General Motors at its Shreveport, Louisiana plant…

The GM chapter V: the brand dies

2008 – 2010

The review: On 3 June 2008, with fuel prices high and large-SUV sales collapsing, General Motors announced it was considering the sale or closure of the Hummer brand. The Mishawaka consequence came first and locally: in January…

The MV-1: a vehicle built for wheelchair passengers

2008 – 2016

The contract: The Commercial Assembly Plant's first post-Hummer product came from a startup. The Vehicle Production Group — founded in 2006 in Miami, Florida; AM General's 2008 contract announcement located it in Troy, Michigan…

The C-Series kit: the Humvee as a kit car

2012 – 2013

Announced, at announced strength: One civilian thread outlived the brand. With GM holding the Hummer trademark, AM General returned to the civilian market under its own name: the HUMVEE C-Series kit, announced on 2 August 2012…

Building Mercedes-Benz: the R-Class years

2015 – 2017

The SF Motors episode: announced, and what was accomplished

2017 – 2019

The sale: On 22 June 2017 AM General announced the sale of the Commercial Assembly Plant to SF Motors — SF Global, a subsidiary of the Shanghai-listed Chongqing Sokon Industry Group, with its headquarters in Silicon Valley. The…

Electric Last Mile: the plant builds again, briefly

2020 – 2022

The successor: Electric Last Mile Solutions was formed in 2020 by James Taylor — the former SF Motors chief executive — and Jason Luo, and carved its business out of the SF Motors/Sokon operation by agreements of September 2020.…

Mullen, and the plant passes to GEM

2022 – 2025

The purchase: On 30 November 2022 Mullen Automotive acquired the ELMS assets out of the liquidation — the Mishawaka factory, the intellectual property, and the inventory — for $105 million in cash, and announced the plant as a…

Ownership: the Perelman venture and KPS

2002 – 2020

MacAndrews & Forbes: Renco's long hold ended in a venture. On 20 August 2004 Ronald Perelman's MacAndrews & Forbes formed a joint venture with the Renco Group that gave Perelman 70 percent of AM General. The venture held the…

The military line never stopped: the contract course

2010 – 2022

Foreign military sales: Through the years when the commercial plant cycled through its ventures, Plant 1's work ran on the unglamorous engine of foreign military sales and support contracts. The documented course: in August 2010…

The JLTV recompete: the successor's contract

2023

The award: On 9 February 2023 the Army awarded AM General the follow-on production contract for the Joint Light Tactical Vehicle — the armored truck developed to succeed the Humvee in the roles the Iraq armor crisis had exposed.…

The JLTV's hard second act, and the Humvee's new money

2025 – 2026

The Army changes its mind: In 2025, under the Army Transformation Initiative, the Army moved to stop buying what it called obsolete capabilities — the JLTV and the Humvee among them; an April 2025 memorandum from the Secretary of…

The workforce and Local 5

1933 – 2026

The oldest local in the UAW: The union on the Mishawaka floor is older than the company, and it arrived by the same road. UAW Local 5 began in 1933 as AFL Local Union 18310, representing Studebaker workers in South Bend; in 1935…
