Kenya has cemented its position as East Africa’s dominant military spender after allocating an estimated $1.47 billion, equivalent to Sh190.25 billion, to defence in 2025, according to new data from the Stockholm International Peace Research Institute (SIPRI), a global authority on arms and military expenditure tracking.
The latest figures place Kenya at the top of regional defence spending charts, widening its lead over neighbours and reinforcing its status as the principal military power in the East African bloc at a time of rising insecurity, shifting alliances, and rapidly evolving warfare technologies.
The 17 percent year-on-year increase from Sh162.64 billion in 2024 reflects an accelerated modernisation drive within the Kenya Defence Forces (KDF), driven by persistent threats from Al-Shabaab militants along the Somalia border, emerging drone warfare risks, and broader instability across the Horn of Africa.
SIPRI, the Stockholm International Peace Research Institute, defines military expenditure broadly to include salaries, pensions, operational costs, procurement of arms and equipment, research and development, infrastructure, and command systems. Under that definition, Kenya’s defence footprint continues to expand not only in procurement but also in administrative and operational intensity.
Despite the increase, Kenya’s growth rate in military spending slowed compared to 2024’s sharper 19.2 percent expansion, suggesting a moderation phase after years of aggressive procurement cycles. However, the country’s military burden rose slightly to 1.07 percent of GDP in 2025, underscoring the increasing fiscal weight of defence within national budgeting priorities.
Within East Africa, Kenya remains decisively ahead. Uganda spent approximately Sh167.9 billion, while Tanzania allocated about Sh133.4 billion over the same period, according to SIPRI estimates. Ethiopia, once a major regional spender due to its internal conflict, saw its defence expenditure drop sharply by 24.6 percent to about Sh68.4 billion following the easing of hostilities after the 2022 peace agreement.
The figures highlight a shifting regional security landscape in which Kenya is not only the most stable large economy but also the most militarised in terms of sustained investment in defence capacity.
Across Sub-Saharan Africa, Kenya ranks third in military spending after Nigeria and South Africa, reflecting both its strategic importance and its exposure to cross-border security threats. The region as a whole spent about $23.3 billion (Sh3 trillion) on defence in 2025, a 7.4 percent rise from the previous year, with conflict zones such as the Democratic Republic of Congo and South Sudan driving much of the growth.
Globally, military expenditure reached an estimated $2.887 trillion in 2025, with the United States, China, Russia, Germany, and India accounting for the majority share. SIPRI data shows that defence spending continues to climb worldwide amid escalating geopolitical tensions and the diffusion of advanced military technologies.
For Kenya, the drivers of increased expenditure are increasingly technological rather than purely manpower-based. Defence planners have cited rapid obsolescence of equipment, the rising cost of upgrading systems, and the need to counter drone-enabled threats as key budgetary pressures. A United Nations Institute for Disarmament Research assessment has warned that non-state armed groups in Africa are rapidly developing interest in unmanned aerial systems, increasing the urgency for air defence upgrades.
This concern is reflected in recent Treasury disclosures showing that Kenya has secured a Sh6.1 billion Israeli-backed facility to acquire advanced missile defence capabilities. The financing, expected to be disbursed in the 2026 financial cycle, signals a deeper shift towards layered air defence systems capable of intercepting aircraft, drones, and precision-guided weapons.
The move follows earlier efforts, including a Sh1 billion financing arrangement for a Spyder surface-to-air missile system designed to intercept low-altitude aerial threats. Such systems are increasingly seen as essential in modern asymmetric warfare, particularly in regions where militant groups are adopting commercially available drone technologies.
Kenya’s defence procurement history indicates diversified sourcing, with past acquisitions linked to suppliers in Türkiye and the United States, reflecting a pragmatic approach to balancing strategic partnerships and operational requirements.
While official SIPRI data does not disclose specific arms contracts, analysts note that Kenya’s procurement strategy has shifted steadily toward mobile, technology-driven systems rather than traditional heavy armour, aligning with global trends in modern warfare.
However, the expansion in defence spending is not without constraints. Budget documents from the National Treasury highlight persistent structural pressures, including pending bills, limited fiscal space, staff shortages, land acquisition costs, and increasing operational demands linked to border security and disaster response.
These constraints suggest that while Kenya is expanding its military capability, it is doing so within a tightening fiscal environment where competing priorities such as infrastructure, health, and education also demand attention.
Regionally, the contrast is stark. Ethiopia’s declining expenditure reflects post-conflict stabilisation, while South Sudan and the Democratic Republic of Congo continue to show sharp increases driven by internal violence and insurgencies. Nigeria remains Sub-Saharan Africa’s largest military spender, largely due to prolonged counterinsurgency operations.
Kenya’s trajectory, however, is distinct in that its spending growth is not solely reactive but also anticipatory, shaped by the need to modernise forces in response to evolving hybrid threats that blend insurgency, cyber risks, and unmanned systems.
As the regional security environment remains volatile, Kenya’s rising defence budget signals both strategic ambition and mounting pressure. The challenge for policymakers will be balancing military preparedness with long-term fiscal sustainability, especially as defence continues to command a growing share of government expenditure.
