Overview
Bofors is a Swedish arms and defense brand whose industrial roots reach back to an ironworks established at the Bofors site in 1646 and whose modern corporate identity was created with the formation of Aktiebolaget Bofors-Gullspång in 1873. Initially a steel producer, the company entered weapons manufacturing as Swedish gunmakers increasingly adopted modern cast and forged steel. It opened its first cannon workshop in 1884 and gradually developed from a supplier of gun steel into a major designer and manufacturer of artillery, naval weapons, anti-aircraft systems, ammunition-related products, missiles, and other military technologies. The company’s historical development was closely connected with Karlskoga, where the works became a major employer and helped drive the town’s industrial and demographic growth. Alfred Nobel owned Bofors from 1894 until his death in 1896 and helped steer it toward a more diversified industrial structure involving cannon production, explosives, and chemical manufacturing. A wholly owned explosives and chemicals subsidiary, AB Bofors Nobelkrut, was created in 1898. Bofors expanded its position in Swedish artillery during the early twentieth century, including through the acquisition and closure of the Finspång gun works in 1911. The corporate name was shortened to AB Bofors in 1919. After the First World War, Bofors entered into cooperation with the German Krupp group. The arrangement transferred technical knowledge and enabled the development or manufacture of certain artillery designs at a time when the Treaty of Versailles restricted Germany’s weapons industry. The relationship, which included limits on exports to several victorious Allied powers, contributed to Bofors’s growth but also connected the company to the politically sensitive system by which German arms expertise was maintained outside Germany. Swedish legislation later restricted foreign ownership of military industries, and Krupp-related ownership in Bofors was unwound in the 1930s. Bofors became internationally best known for its 40 mm automatic anti-aircraft gun. The L/60 version was used widely during the Second World War by forces on both sides of the conflict, while later 40 mm L/70 variants continued the product family’s service life. The company also produced the 37 mm anti-tank gun, 57 mm and 120 mm naval guns, coastal artillery, field howitzers, anti-tank missiles, surface-to-air missile systems, and anti-submarine rocket launchers. Many systems were exported, manufactured under license, or integrated into foreign armored vehicles, ships, and air-defense networks. Ownership changed substantially at the end of the twentieth century. Saab acquired the Celsius Group, then Bofors’s parent, in 1999. In 2000, United Defense Industries acquired Bofors Weapons Systems, the heavy-weapons division, while Saab retained missile-related activities. BAE Systems acquired United Defense in 2005. The heavy-weapons business became BAE Systems Bofors within the Swedish BAE Systems organization, while the missile side continued under Saab-linked branding, including Saab Bofors Dynamics. Accordingly, Bofors is best understood today as a continuing defense name and industrial heritage rather than a single independent corporation encompassing all historical Bofors activities. Its legacy remains particularly visible in artillery, naval weaponry, and air defense.
History
The Bofors industrial site originated with a hammer mill and forge established in 1646 after permission was granted to build an ironworking facility at the location. The works passed through several owners during the eighteenth century, including Johan Eberhard Geijer and his brother Emanuel af Geijerstam. The modern company was formed in 1873 as Aktiebolaget Bofors-Gullspång, at a time when Swedish steelmaking was becoming increasingly important to the manufacture of artillery. Bofors first supplied cast and forged steel to established gunmakers, but soon moved into complete weapons production. Its first cannon workshop opened in 1884. Alfred Nobel acquired the company in 1894 and owned it until his death in 1896. During this period Bofors developed beyond iron and steel production, combining cannon manufacturing with explosives and chemical activities. AB Bofors Nobelkrut was established in 1898 as a wholly owned subsidiary. Bofors’s position in Swedish artillery strengthened when it acquired and closed the competing Finspång gun works in 1911, and the company adopted the shorter name AB Bofors in 1919. The post-First World War period brought a significant relationship with Krupp. Because the Treaty of Versailles restricted Germany’s development and export of artillery, Krupp cooperated with Bofors through technical information, licensing, employee access, and related industrial arrangements. Bofors also assumed certain contracts associated with Krupp. A 1921 agreement restricted the export of some Krupp-derived equipment to countries including the United Kingdom, United States, France, Italy, and Japan. Krupp-related interests were later affected by Swedish restrictions on foreign ownership of military companies. In 1935, legislation led to the liquidation of the relevant foreign-owned holding structure and the transfer of its Bofors shares to Swedish ownership. During the twentieth century, the Bofors works became central to Karlskoga’s economy. Employment at the site approached 10,000 by 1970, and the company’s operations contributed to the city’s population growth. The company’s weapons portfolio expanded across automatic cannons, anti-tank weapons, field artillery, coastal defense, naval guns, missiles, and anti-submarine systems. Its 40 mm automatic gun became the most recognizable Bofors product. The L/60 model was widely deployed during the Second World War, and the later L/70 family extended the design’s relevance. The 37 mm anti-tank gun was also adopted by multiple countries and produced under license. Bofors’s late twentieth-century corporate history was shaped by consolidation in the Swedish defense sector. Saab purchased the Celsius Group in 1999. In 2000, United Defense Industries bought Bofors Weapons Systems, the heavy-weapons division, while Saab maintained the missile business. BAE Systems acquired United Defense in 2005, resulting in the Bofors heavy-weapons activities becoming part of BAE Systems Bofors, a unit of BAE Systems AB in Sweden. Saab’s missile operations continued under Saab-linked names, including Saab Bofors Dynamics. The Bofors name also became associated with a major political and legal controversy in India. A 1986 contract for 410 155 mm howitzers was followed by allegations in 1987 that illegal commissions had been paid to influential politicians and defense officials. The controversy damaged the standing of the Indian government and became an important issue in the 1989 election. It remains one of the most prominent scandals connected with the company’s history. Today, Bofors represents a combination of historic Swedish industrial identity and successor defense businesses operating under BAE Systems and Saab ownership.

Products and positioning
A Swedish-origin defense brand associated with durable, export-oriented artillery, naval weaponry, and integrated weapon systems.
Air-defense and naval gun
Bofors 40 mm automatic gun
The 40 mm family, especially the L/60 model, became Bofors’s most internationally recognizable weapon. It was used extensively as an anti-aircraft gun by land forces and naval services during the Second World War, including by opposing sides. Later L/70 versions continued the family with updated performance and remained relevant in postwar air-defense and naval applications.
Anti-tank artillery
Bofors 37 mm anti-tank gun
The 37 mm L/45 anti-tank gun was a widely exported prewar and Second World War weapon. It was adopted or manufactured under license in several countries and was installed on or associated with a range of armored vehicles, including the Vickers 6-ton, M39 Pantserwagen, and Polish 7TP.
Naval weapon
Bofors 57 mm naval automatic gun
Bofors developed several 57 mm automatic naval guns for shipboard use. The family formed part of the company’s long-standing naval armament business, supplying compact rapid-fire weapons for surface combatants and other vessels.
Field artillery
Bofors 155 mm field howitzers
Bofors produced 155 mm field artillery systems including the FH77 series. These weapons represented the company’s role in heavy land artillery and were exported internationally. The FH77 lineage later informed the development of the FH77BW Archer self-propelled artillery system under successor Bofors operations.
Self-propelled artillery
Archer
Archer is a 155 mm self-propelled artillery system derived from the Bofors FH77 artillery family. It combines a wheeled platform, automated loading, and rapid shoot-and-scoot operation. The system is associated with the BAE Systems Bofors successor business rather than with an independent historical Bofors corporation.
Anti-tank missile
BILL
BILL, an acronym derived from Bofors Infantry Light and Lethal, is a Swedish anti-tank missile family associated with the missile activities that continued under Saab-linked successor branding. It was designed for infantry use against armored targets.
Surface-to-air missile
RBS 70
RBS 70 is a Swedish short-range air-defense missile system associated with Bofors missile development and later Saab operations. The system was designed to engage low-altitude airborne targets and became an important export product in Sweden’s ground-based air-defense portfolio.
Anti-tank missile
BANTAM
BANTAM, short for Bofors Anti Tank Missile, was an early Bofors anti-tank missile project and product family. It illustrates the company’s expansion from conventional guns into guided weapons and infantry anti-armor systems.
Anti-submarine weapon
Bofors 375 mm multi-barrel anti-submarine rocket launcher
This multi-barrel launcher was developed for naval anti-submarine warfare. It formed part of Bofors’s broader naval weapons portfolio, which extended beyond guns into shipborne systems for engaging submerged targets.
Controversies
1987
Bofors affair in India
Following a 1986 contract for 410 155 mm howitzers, Swedish Radio alleged that Bofors had paid illegal commissions worth approximately 600 million Indian rupees to influential Indian politicians and senior defense officials. The allegations became a major political controversy, damaged the reputation of the Rajiv Gandhi government, and contributed to its defeat in the 1989 election.
