Verdict

Edge: Chile

Chile holds a clear overall edge over Argentina, sustained by a larger and better-funded force (roughly $5.0B at 1.5% of GDP against Argentina's $3.8B at 0.6%), a modern F-16 and Leopard 2A4 backbone, and a submarine-equipped navy. Argentina's greater population and territorial depth are real assets, but its combat aviation and undersea capability remain in reconstitution.

Domain by domain

Air power Edge: Chile

🇦🇷 Argentina241 aircraft but only 26 combat types, historically A-4 Skyhawks; 24 ex-Danish F-16AM/BM acquired to restore supersonic capability, with integration at Tandil still ongoing. 101 helicopters support transport and mountain operations.

🇨🇱 Chile81 combat aircraft from 277 total, centred on 46 F-16s (MLU and Block 50) with AMRAAM-capable radars, backed by F-5 upgrades, tankers and AEW assets. Mature training and sustainment pipeline.

Naval power Edge: Chile

🇦🇷 Argentina42 warships, no submarines in operational service; core is three Almirante Brown-class (MEKO 360) destroyers plus MEKO 140 corvettes and OPVs. Focus on EEZ patrol and anti-IUU fishing in the South Atlantic.

🇨🇱 Chile75 warships including four submarines (two Scorpène, two Type 209), Type 23 frigates and Dutch-built escorts, plus amphibious and logistic ships. Blue-water orientation across a 6,435 km Pacific coastline.

Ground forces Edge: Chile

🇦🇷 Argentina231 MBTs, essentially the domestically produced TAM undergoing 2CA2 modernisation with Israeli systems; around ten brigades including mountain, armoured and airborne units. Wheeled Stryker-class acquisition planned for mobility.

🇨🇱 Chile386 MBTs, including 186 Leopard 2A4 supported by Marder 1A3 IFVs and M109 self-propelled howitzers across six divisions. Procurement prioritises high-altitude and northern-border mobility.

Defense industry & budget Edge: Chile

🇦🇷 Argentina$3.8B on a $638B GDP — just 0.6%, among the lowest in the region; retains FAdeA aviation and naval yards (Tandanor, Río Santiago) but chronic underfunding limits readiness and spares.

🇨🇱 Chile$5.0B on a smaller $330B GDP (1.5%), historically underpinned by copper-linked funding rules; ASMAR and FAMAE provide shipbuilding and munitions depth. Higher spend per capita and sustained recapitalisation.

Manpower & mobilisation Edge: Chile

🇦🇷 Argentina103,000 active plus 31,250 paramilitary drawn from 45.7 million people; large territorial base and conscript-era reserve structures, but low funding constrains training tempo and mobilisation quality.

🇨🇱 Chile114,000 active, 40,000 reserves and 44,700 paramilitary from 19.8 million — a far higher share of population under arms, with Carabineros providing an additional militarised internal-security tier.

Wildcards

The Andes as a barrier A 5,000 km frontier along the Andes favours defence on both sides. High passes channel any ground movement into a handful of predictable corridors, blunting armoured superiority and rewarding mountain infantry and air interdiction.
Two-ocean geometry Argentina faces the Atlantic, Chile the Pacific, with the Magellan and Beagle passages as the only junctions. Naval superiority translates into leverage mainly at the southern approaches, not along the shared land border.
Western alignment on both sides Argentina is a US Major Non-NATO Ally seeking NATO global-partner status; Chile joins RIMPAC and holds a US state partnership. Overlapping patronage, arms sourcing and confidence-building measures make escalation between them politically costly.

Outlook
