and employs 3,200 people. The plant is situated on a site, with a manufacturing facility. It formerly manufactured all Jaguar saloon and sports cars, prior to production of complete cars at the site concluding in May 2024. After the production of complete cars ended at the site, the factory was modified into making pressed steel panels (that is, body components, not complete cars) for Jaguar cars.
The site was first developed as Castle Bromwich Aircraft Factory (CBAF), a
shadow factory for the production of aircraft by the car industry as part of the rearmament of the UK in the pre-Second World War era. After initial problems it was brought under the control of aircraft manufacturers and became one of the largest producers of aircraft during the war.
History
Castle Bromwich Aircraft Factory
Nuffield: 1936–1940
In 1936, the British government had formalised a plan under the
Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force and civil aviation that existed from 1918 to 1964. It was under the political authority of the ...
called the Shadow factory plan to increase capacity within Britain's aircraft industry. Headed up by automotive pioneer
Herbert Austin, the plan was to create nine new factories and add additional capacity and facilities to Britain's existing car manufacturing plants to enable them to quickly turn to aircraft production should the political situation in Europe change towards war.
In 1936, the Air Ministry purchased a parcel of land opposite
Castle Bromwich Aerodrome which encompassed an old
sewage works. Developed and managed by the
Nuffield Organization, owners of

[Price 1982, p. 67.] Although Morris Motors under
Lord Nuffield (an expert in mass motor-vehicle construction) managed and equipped the factory, it was funded by government money. When the project was first mooted, it was estimated that the factory would be built for £2,000,000, however, by the beginning of 1939, this cost had doubled to over £4,000,000.
[McKinstry 2007, p. 145.] The Spitfire's stressed-skin construction required precision engineering skills and techniques outside the experience of the local labour force which took some time to train. Aircraft and sub-assemblies were taken across the Chester Road to Castle Bromwich Aerodrome; though early plans included an aerial bridge from E block to the airfield. Very large hangar-like buildings were erected on the east side of the airfield, which were originally referred to as 'Erecting Sheds', where aircraft were prepared for flight testing. They were for the most part referred to by personnel as the 'Flight Sheds'.

or
Rotol propellers. The first Mk II flew on 24 September 1939.
However, even as the first Spitfires were being built in June 1940, the factory was still incomplete and there were numerous problems with the factory management which ignored tooling and drawings provided by Supermarine in favour of tools and drawings of its own designs. Meanwhile, the workforce, while not completely stopping production, continually threatened
strikes or "slow downs" until their demands for higher than average pay rates were met. By May 1940, Castle Bromwich had not yet built its first Spitfire in spite of promises that the factory would be producing 60 per week starting in April.
Key players, such as Alex Henshaw, viewed the problems as primarily those of poor management during the initial phase. Workers worked twelve-hour on and twelve-hours off until bombings forced a switch to a three-shift, eight-hour system. Henshaw attended the diamond jubilee in 1996 of the founding of the CBAF, hosted by Jaguar Cars Limited in the old factory and remained fulsome in his praise for the workforce until his death.

Lord Beaverbrook as the

was bombed, and production there temporarily stopped. CBAF went on to become the largest and most successful plant of its type during the 1939–45 conflict. As the largest Spitfire factory in the UK, by producing a maximum of 320 aircraft per month, it built over half of the approximately 20,000 aircraft of this type. By the time production ended at Castle Bromwich in June 1945, a total of 12,129 Spitfires (921 Mk IIs,
[''Air International'' 1985, p. 187.] 4,489 Mk Vs, 5,665 Mk IXs, and 1,054 Mk XVIs
) had been built.
Subsequently receiving an order for 200 production aircraft, the first CBAF Lancaster was flown on 22 October 1943 by Alex Henshaw. Given the airframe number HK535 and fitted with Merlin 22 engines, it was issued to

The film ''Jane Brown Changes Her Job'' (1941) was made in the factory, and scenes for the 1943 film ''
Millions Like Us'' were shot there, with employees serving as extras.
Some original wartime features can still be seen such today, such as the faded remains of green camouflage paint. This can still be seen on the top of some older production buildings, such as F Block, that is now used as trim and final assembly for the Jaguar XJ. Close inspection will also reveal that all the cast-iron hoppers of the factory's rainware have a winged-roundel motif cast into them. At the Jubilee celebrations in 1997, a plaque was unveiled by Alex Henshaw just inside the old wartime main gates to the factory site. At the moment of unveiling, ex-Red Arrows founder Ray Hanna made a single pass over the ceremony in a Spitfire MkIX, MH434. This aircraft was not only built at the CBAF, but was test-flown by Henshaw himself. The aircraft had been specially named for the occasion by Henshaw at Elmdon Airfield (now called Birmingham International Airport). After the unveiling, both Henshaw and Hanna attended a celebratory luncheon with many local dignitaries and many former CBAF employees. The whole event was supported and funded by Jaguar Cars Ltd.

" since manufacturing of the XJ was to end in July.
Weeks later, on 5 July 2019, JLR announced its intention to build a new
electric XJ saloon, replacing the manufacturing of the conventional
Jaguar XJ (X351) at Castle Bromwich, "safeguarding the jobs of 2,500 people"
(or 2,700 people, according to BBC News). Manufacturing of the new model was expected to start in autumn 2019, after an investment of £1bn in upgrades to the facility.
A BBC report indicated that the plant "also produces the Jaguar XF, XE and F-Type" as of mid-2019, but the XJ was essential for the continuation of the manufacturing facility. Without the new electric model, the Castle Bromwich plant would "effectively be dead", according to
David Bailey, a professor of business economics at Birmingham Business School.
