Armenia spends approximately $1 billion on defence — roughly 5% of GDP — in an emergency modernization drive following its catastrophic losses in the 2020 Nagorno-Karabakh war and the September 2023 Azerbaijani offensive that triggered the entire Karabakh Armenian population's exodus. Having lost confidence in its CSTO ally Russia, Yerevan has pivoted sharply toward France, India, and other Western partners for arms procurement while pursuing EU membership prospects.
Armenia's defence budget has nearly doubled since 2020 as emergency supplementals funded post-war rearmament. The 2025 appropriation is approximately AMD 550 billion ($1 billion USD), representing an extraordinary ~5% of GDP for a small economy. Emergency procurement in 2023-24 was driven by the September 2023 lightning Azerbaijani offensive that retook Nagorno-Karabakh in 24 hours — humiliating Armenian-backed Karabakh Defense Forces and triggering the exodus of 100,000 ethnic Armenians. France's CAESAR 155mm self-propelled howitzers, India's Pinaka multi-barrel rocket launchers, and various Indian artillery shells and small arms have been the primary new acquisitions. Russia's role as supplier has sharply contracted following CSTO's failure to respond in 2023.
The Armenian Armed Forces field approximately 44,800 active personnel organized around the Army (the dominant service), Air Force, and Air Defence Force. The Army operates T-72 and T-72B tanks, BMP-2 IFVs, and inherited Soviet artillery — supplemented now by French Caesar SPHs and Indian Pinaka MLRS. The Air Force has limited combat capability; Su-30SM fighters acquired from Russia remain the primary fast jet. Armenia lost significant materiel in 2020-2023, including Smerch MLRS, Iskander-M tactical ballistic missiles, and substantial stocks of armour. Reconstruction of force structure is a multi-year priority. Conscription provides the personnel base with 24-month service.
Armenia has a limited but historically significant defence-technical sector. Soviet-era facilities in Yerevan produced electronics and guidance components; some have been revived. Armenia has no domestic capacity for tanks, aircraft, or advanced missiles. The pivot away from Russia has exposed Armenia's dependency: most existing heavy equipment is Russian-origin, requiring Russian spare parts that are now politically difficult to obtain. India has emerged as a key strategic supplier — less politically complex than Western governments and willing to provide lethal systems without the conditionality of EU arms export controls. France's Caesar deal included technology transfer discussions for maintenance infrastructure.
Armenia's security environment is defined by its ongoing standoff with Azerbaijan. Despite a November 2020 ceasefire (brokered by Russia), Azerbaijan launched further military actions in May 2021 (Syunik incursion), March 2022, and September 2022 before the decisive September 2023 offensive that ended Karabakh's Armenian governance. Armenia and Azerbaijan are negotiating a formal peace treaty but key issues — border demarcation, Lachin corridor, constitutional references to Karabakh — remain unresolved as of 2025. Tensions on the Armenia-Azerbaijan border in Tavush Province (April 2024) produced further clashes. Iran has signalled concern about Azerbaijani ambitions toward the Zangezur corridor (which would connect Azerbaijan and Turkey through Armenian territory).
France delivered the first Caesar 155mm SPH battery to Armenia in early 2024, marking the most significant Western arms transfer to Yerevan in its post-Soviet history. India's Pinaka MLRS batteries were delivered in 2023-24. Armenia formally suspended its participation in CSTO exercises in 2024 and Prime Minister Pashinyan stated Armenia would not recognize Russia as a security guarantor. Armenia applied to join the EU's Eastern Partnership enhanced tracks and polling showed majority support for EU membership. Peace treaty talks with Azerbaijan continued under EU and US mediation through 2025, with partial agreement on border demarcation reached in segments.
Armenia spent approximately $1 billion on defence in 2025 — around 5% of GDP — one of the highest ratios in its history. Spending surged after the 2020 war and 2023 Nagorno-Karabakh loss triggered emergency rearmament.
Russia's CSTO failed to respond to Azerbaijan's military actions in 2021-2023 despite Armenia's status as a CSTO member. The September 2023 offensive that ended Karabakh Armenian rule without Russian intervention shattered confidence in Moscow as a security guarantor, prompting Armenia to seek French, Indian, and Greek arms.
Azerbaijan launched a 24-hour offensive on September 19, 2023, that overwhelmed Karabakh Armenian defense forces. A ceasefire was signed the next day. Over 100,000 ethnic Armenians fled to Armenia within days, ending 30 years of Armenian governance over the enclave. Azerbaijan now fully controls the territory.
Armenia is pursuing closer EU ties — a majority of Armenians now support EU membership in polls, and the government has applied for enhanced partnership tracks. NATO membership is not currently on the agenda, partly due to geographic isolation from NATO territory and ongoing treaty negotiations with Azerbaijan.
