About US

Arsenal USA represents Arsenal's long-term commitment to the United States and to deeper participation in the U.S. defense industrial base.

Backed by the manufacturing capabilities and experience of Arsenal in Bulgaria, our U.S. operation is focused on developing lasting relationships with government customers, defense contractors, technology companies, and industrial partners across the United States.

For generations, Arsenal, Bulgaria has been an industrial manufacturer first.

Our capabilities span small-caliber ammunition, weapons, energetic materials, components, and a broad range of defense products, supported by vertically integrated manufacturing, engineering, testing, and production infrastructure.

This industrial foundation allows us to approach the U.S. market not simply as an exporter, but as a potential manufacturing and technology partner.

Arsenal USA was established to expand the Group's engagement with the U.S. defense market and create a permanent platform for cooperation with American industry.

Our priorities include:

— Supporting U.S. Government and defense-sector requirements
— Building partnerships with U.S. prime contractors and manufacturers
— Expanding U.S.-based manufacturing and supply-chain capabilities
— Exploring joint ventures, technology partnerships, and industrial cooperation
— Investing in emerging defense technologies and innovative companies
— Connecting Arsenal's European manufacturing base with U.S. industrial capacity and expertise

The future of defense manufacturing increasingly depends on cooperation between established industrial producers and emerging technology companies.

Arsenal USA is actively interested in partnerships where our production capabilities, manufacturing know-how, infrastructure, and international market experience can complement U.S. technology, engineering, and innovation.

We believe these relationships can accelerate the transition from promising technology to scalable production."

Company profile

Over 148 years history

1878

Foundation of the Company

The history of Arsenal JSCо dates back to 1878, when, by decree of Prince Alexander Dondukov-Korsakov, a special military manufacturing facility was established in Ruse to support the needs of the newly formed Bulgarian Army – known as the Ruse Artillery Arsenal.

1884

First Bulgarian Director

Until 1884, the Ruse Arsenal was managed by Russian officers. On February 28, 1884, Professor General Simeon Nikolov Vankov was appointed as the first Bulgarian Director of the factory.

1891

Relocation to Sofia

At the beginning of 1891, by Decree No. 10 of Prince Ferdinand, the factory was relocated to Sofia and thus the Sofia Artillery Arsenal, headed by General Stefan Belov was established.

1924

Establishment in Kazanlak

In 1924 by the Decree of Tzar Boris III and by law adopted by the XXI Regular National Assembly, due to strategic reasons the factory was moved to Kazanlak under the name of State Military Factory.

1927 – 1942

Expansion and Technological Development

The law established the basic function of the State Military Factory -"to produce and repair all military equipment necessary for the army, the police, the border troops and all state security organs, as well as the testing of new models". Besides the rifles, pistols, cartridges manufactured at the Sofia Artillery Arsenal, for the first time in Kazanlak were produced primers, gas masks (1927-29), double-base and single-base artillery powders (1936-42), brake recoil fluids for the canons and the production of artillery projectiles was modernized. In the course of the years the factory was enlarging, renovating and developing to become a considerable part of the national economy. After the World War II started the production of new products of primary importance for the country - three-furrow ploughs, disk harrows, batteries, diesel engines, electric motors, as well as the repair of optical systems and the production of the first lathes and vertical milling machines.

1947 – 1948

Industrial Reorganization

On April 1, 1947, by Decree of the Council of Ministers the State Military Factory became a self-supported economic unit. By Decree of the Council of Ministers of 30.12.1948, the Bulgarian Military plants were consolidated under the special State holding "Metalchim", and the State Military Factory-Kazanlak passed from the Ministry of Defence to Ministry of Industry and Crafts under the name of "Factory-10".

1956 – 1958

Military and Civil Production

During the years 1956-58 "Factory-10" started the production of a recoilless canon B-10, as well as of assault rifles. The first rifle was manufactured in 1958 and the jubilee-one million-in 1982. The factory diversified into civil purpose machine-tool production: Drilling Machines BK-20 and BK-32 and Milling Machines FU-250 and FU-320.

1960 – 1964

Plant for Hard-Alloy Inserts

Later on, were created the conditions for designing and serial manufacturing of other machine-tools with high technical and economic parameters - a large range of milling machines, special purpose machines, units etc. On 01.12.1960 started the production of hard-alloy inserts. By Decree of the Council of Ministers from 10.08.1964 the factory was renamed to United Industrial Plant "Friedrich Engels" and became a powerful centre of the national machine building and the military industry. In this connection the factory adopted a new structure divided into seven independent factories.

1966

First Bulgarian Car

In 1966, at the premises of UIP "Friedrich Engels", the assembly of the "Bulgar Renault 8" cars was performed, and the production of anti-tank recoilless systems began.

1967

Scientific Development and New Products

In 1967 a Development Centre was established, which in 1984 grew into an Institute for Machine-tools. Over the following years, the company expanded its manufacturing capabilities through the establishment of: - Factory for springs; - Factory for special purpose machinery; - Factory for optional equipment (non-standard); - Production of powders, primers and pyrotechnic products; - Workshop for CNC machines; - Computing center etc.

1977 – 1989

New Licensed Weapons

From 1977 till 1989 the factory was known in Bulgaria and abroad as "F.Engels" Machine Building Plant. The machinery fleet is continually improved and modernized thus enlarging the possibilities for a wider scale of production. Simultaneously grew the number and the qualification of the specialists.

1989 – 1999

Transition to a Market Economy

On 12.06.1989 the company was registered as Arsenal State-Owned Company, and on 20.12.1991 it was transformed into a Sole Owner Joint Stock Company. During this period started the production of new machining centers under the license of the Japanese company "Yamazaki". A new Factory for the production of hard-alloy mixtures and inserts and a monolith module system "VARILOCK" was established and equipped under the license of the Swedish company "Sandvik Coromant" A plant for synthetic diamond was opened in collaboration with specialists from the Institute for Superhard Materials-Kiev. The company successfully adapted to the new market conditions and aligned its products and technologies with NATO standards. As of December 3, 1999, the factory is transformed into a joint-stock company Arsenal JSCo, with the following principal activities:

1999

Modernization and Expansion of Manufacturing Capabilities

The period from 1999 to 2026 marks a significant phase of modernization, technological advancement, and expansion of the company’s manufacturing capabilities. In 2009, state-of-the-art production facilities were introduced, significantly enhancing operational efficiency, product quality, and competitiveness. In 2024, a new high-tech manufacturing facility was commissioned, built in accordance with the highest industrial standards. The plant features advanced production lines, automated systems, and specialized equipment for machining, quality control, and high-pressure testing. Robotic solutions and modern manufacturing technologies were integrated to ensure precision, reliability, and operational excellence. At the same time, the company launched a strategic expansion program for its propellant production facilities. The first phase includes the modernization of existing facilities and the reactivation of idle equipment, increasing annual production capacity from 1,500 to 3,000 tones. Completion of this phase is scheduled for the second half of 2026. Through these investments, the company continues to strengthen its position as a modern industrial enterprise, combining decades of expertise with innovative technologies and the highest standards of quality.
