GA is led by Gerry P. Amante (Director) and Arnold Rafael Y. Depakakibo (assistant director).^[3]

GA was established through Republic Act No. 1884, which was signed into law on June 22, 1957,^[4][5] the Arsenal is a line bureau under the Department of National Defense.^[2] It was only on March 7, 1967, that a presidential proclamation on its present site at Limay, Bataan was declared.^[6] Accordingly, on October 12, 1967, the groundbreaking materialized at the spot where the statue of General Antonio Luna now stands. The 514th and 564th Engineering Construction Battalions of the 51st Engineering Brigade of the Armed Forces of the Philippines (AFP) were tasked with the construction of GA facilities.^[2]

On August 15, 1971, the first SAA cartridge rolled out of the GA's production assembly line. Three years later, the integrated SAA manufacturing began, with all components - case, primer, propellant powder, and bullet assembled into a complete cartridge.

On February 23, 1995, Republic Act 7898, otherwise known as the AFP Modernization Act, was enacted.^[7] Republic Act 7898 likewise provides for the modernization of the Government Arsenal for the development of production capabilities to enhance self-sufficiency in defense requirements. Specifically, Section 12 of this Act mandates that "the government arsenal shall be utilized in the production of basic weapons, ammunition and other munitions for the use of the Armed Forces of the Philippines and the Philippine National Police (PNP), as well as for the sale and export of products in excess of AFP/PNP requirements."^[4]

As part of the modernization effort, the arsenal, through the Department of National Defense, issued an invitation to bid for a Multi-Station Bullet Assembly Machine for 5.56mm M193/M855 in August 2009.^[8] This marked a significant expansion of existing production lines. Bids failed on December 4, 2009, and on March 10, 2010.^[8]

On November 15, 2012, the Arsenal established its Small Arms Repair and Upgrade Unit (SARUU) to handle the repair, refurbishment, upgrading, and enhancement of the firearms of the military and law enforcement services.^[9]

On November 14, 2018, Arsenal signed a co-production agreement with Samyang Comtech Co. Ltd. of South Korea to manufacturing and testing facilities within the Government Arsenal complex for the produce of armor vests and ballistic helmets.^[10]

On April 5, 2019, the arsenal broke ground for two major production facilities under co-production agreements with South Korean firms: a force protection equipment manufacturing plant in partnership with Samyang Comtech and a 5.56mm magazine manufacturing plant in partnership with Buhueng Precision.^[11][12] The event was attended by Secretary Lorenzana alongside South Korean ambassador Han Dongman, Samyang Comtech Co., Ltd. Inc. Representative Kim Jong-il, BuHueng Precision Co., Ltd. President Min Hung-ki, and Director General Kim Kitaek of the Defense Acquisition Program Administration.^[13]

On May 29, 2021, Secretary Lorenzana inspected GA's Building 27 or the mixing composition room after an explosion took place where two GA employees were killed, which he deemed to be a workplace accident.^[14]

On June 28, 2022, GA and Bataan City officials signed a memorandum of agreement to expand GA's estate in the freeport area.^[15]

On January 23, 2023, DND Secretary Carlito Galvez Jr. proposed that ammo made by GA be turned into training ammo due to concerns about ammunition wastage.^[16]

GA is located in Barangay Lamao, Limay, Bataan on a 370-hectare defense industrial estate.^[17] The area has a total of 370.37 hectares.^[18]

The Government Arsenal Strategic Plan will serve as a guide or roadmap for the acquisition of necessary technologies to enhance the GA's manufacturing capability in collaboration with the various defense industry players and the academe.

The GA Strategic Plan focuses on the following:

Phase 1: Self-Reliance and enhancement of Small Arms Production Capacity

1.1) Acquisition of dedicated production line for 5.56mm and 9mm ammunition.

2.2) Development of the road from the Dam area to the Proposed GA-DIE

2.3) Construction of 30-m and 40-m access bridge

2.4) Construction of Perimeter Fence

2.5) Re-piping of Water line

2.6) Construction of Waste Water Treatment Facility

3. Acquisition of capability and establish Cold Rolling Mill for the local production of metallic raw materials;

4. Establishment of manufacturing facility and equipment for the in-house production of explosives material:

4.1) Acquisition of capability and establish a facility for in-country production of Propellant powder;

4.2) Acquisition of capability and establish a facility for the in-country production of Nitroglycerin and Nitrocellulose

4.3) Acquisition of equipment for in-house production of Trinitroresorcinol (TNR)

Phase 2: New Capability Development

9. Acquisition of necessary equipment and technology for the in-country production/assembly of Cal. 50 ammunition;

10. Acquisition of capability and establish a facility for the manufacture of assault rifle

11. Establishment of Ballistics Testing Center

Phase 3: Other New Capability Development in collaboration with AFP Major Services

12. Collaboration with the Philippine Air Force to establish capability for the in-country production of peculiar air munitions;

13. Coordinate and collaborate with the Philippine Navy for the development of capability in the manufacture of peculiar Naval Ammunition such as; 76mm, 25mm, 20mm and 40mm;

14. Collaboration with various stakeholders to develop the capability for the in-country production of at least the basic mobility equipment for the defense and security establishments;

15. Collaboration with various stakeholders to develop the capability for the production of Combat Clothing and Individual Equipment (CCEI)

16. Collaboration with the various stakeholders to develop capability in the production of communications equipment; and

17. Collaboration with the AF, academe and the other concerned government agencies to develop capability in the production of missile systems.

Small arms ammunition manufactured by the Government Arsenal can be identified by the headstamp code: "RPA".^[19] This acronym stands for "Republic of the Philippines Arsenal".

In 2011, a new standard coding system was adopted by the arsenal following its formulation and final approval in October of the previous year. This replaced the previous coding system which was derived from the product codes of foreign manufacturers using a combination of English and Metric/Système International (SI) units.

The revised system uses simplified alphanumeric designations that make reference to the ammunition's caliber and type for ease of identification while avoiding unnecessary complications caused by the use of mixed English & SI units and designations based on different foreign code systems.^[20]

To improve the accounting and traceability of government-produced munitions, the Government Arsenal has endeavored to implement laser engraving technology into its ammunition production process as part of the modernization of its production lines, making it the first domestic ammunition manufacturer to do so.^[20] This involved the acquisition of a laser marking and packaging machine for use with 5.56mm and 7.62mm ammunition. Information on each ammunition batch produced will be stored in a database allowing for easier accounting of the origin, transfer, receipt, utilization and/or disposal of ammunition.^[21]
