The procurement axis was uneven this week. Brazil produced two contradictory signals — domestic phased-array radar technology validating against the country’s own most modern fighter at Anapolis, while the Marine Corps quietly auctioned the SK-105 light-tank fleet as scrap with no replacement in service.

Argentina received its first cohort of new UNIMOG tactical trucks and quietly added a UH-60 Black Hawk Letter of Request to the post-2025 capability pipeline.

Brazil’s Army formally unified its ASTROS-FOGOS strategic-fires programme into a single architecture pointing toward a domestic tactical ballistic missile. The week’s news was less about contracts signed than about the institutional repositioning that contracts require.

SABER M200 Vigilante radar confronts F-39 Gripen — first 4.5-gen test of a Brazilian phased-array radar

The Brazilian Army deployed the SABER M200 Vigilante air-defense radar to Anapolis between May 11 and May 15, integrating it with organic anti-aircraft artillery units against a Saab F-39 Gripen operated by the FAB.

It was the homegrown radar’s first major confrontation with a 4.5-generation fighter and the most important field-validation event for the Brazilian defense-industrial base in 2026.

The Army Evaluation Center (CAEx) moved engineers from its Marambaia test range, west of Rio de Janeiro and operational since 1948, to Anapolis to run the trial. The radar was integrated with anti-aircraft artillery means of the Army for the first time.

The institutional context is the announced Brazilian programme — up to R$3.4 billion — for a new anti-aircraft system capable of intercepting drones and cruise missiles, contracting starting this year. Army defense investment is projected to roughly double to R$3 billion annually between 2026 and 2031, following a complementary law that excluded up to R$30 billion from the federal fiscal cap.

Successful integration with the F-39 clears the SABER for integration with the Centauro II armored cavalry vehicles already on order, and meaningfully widens the address space for export campaigns. Brazil is among a small group of Latin American countries with the engineering depth to develop phased-array radar in-house — alongside India, Korea, Türkiye, and a handful of European states.

Brazilian Navy retires SK-105 light tanks — Marine Corps now has no armored core

The Cuerpo de Fusileros Navais formally retired its SK-105 A2S Kürassier light-tank fleet on May 29 and sold the airframes as scrap. The decision closes a procurement file opened in 2023, when the Marine Corps stated the intention to replace the Kürassiers by 2032 with a new main battle tank under the VBC Fuz programme.

Otokar (Tulpar in 120mm light-tank configuration) and FNSS (Kaplan MT in 105mm medium-tank configuration) submitted tender entries in May 2025. NORINCO’s VT4 MBT and VN20 heavy IFV remain in the broader VBC CC / VBC Fuz competition.

The operational gap is real. The Brazilian Marine Corps will have no organic main-battle-tank capability until the VBC Fuz contract reaches initial delivery — likely 2030 at the earliest. The retirement signal also matters institutionally.

Selling the Kürassiers as scrap rather than mothballing or transferring them — Uruguay’s Bernardini-modernized M41B/Cs would have been a natural recipient — confirms the Navy’s procurement leadership has accepted a multi-year gap in exchange for technical sovereignty in the replacement decision.

First UNIMOG batch arrives at Rio Cuarto — Ejército ground-mobility pipeline opens

The Ejército Argentino formally received the first batch of Mercedes-Benz UNIMOG tactical trucks at Rio Cuarto in late May, initiating the institutional acceptance, training, and inspection processes for a programme that will replace the Ejército’s largely 1970s-vintage tactical wheeled fleet.

The arrival is consistent with the post-Plan ARMA capability pipeline outlined in Issues #10 and #11, and follows the King Air 360ER MPA Letter of Intent signed for the Armada Argentina on May 21.

The Jefe de Estado Mayor General del Ejército, Teniente General Oscar Santiago Zarich, separately confirmed during the institution’s 216th anniversary ceremony on May 29 that the UH-60 Black Hawk is “one of the helicopters the Ejército will incorporate” — the first time a sitting Army chief has publicly named the platform as a planned acquisition.

Brazilian Army unifies ASTROS-FOGOS into single tactical-ballistic architecture

Under EME/C Ex Ordinance No. 1,703/2026, the Brazilian Army formally restructured its ASTROS-FOGOS strategic-fires programme to unify rocket artillery, cruise projectiles, and ballistic systems into a single architecture.

The resulting platform — identified across the specialist press as S+100 — will operate atop existing ASTROS infrastructure and is configured for what the institution describes as a long-trajectory, broad-coverage role.

The combination of strategic logistics consolidation and the institutional commitment to a domestic tactical-ballistic-missile capability puts Brazil in the second tier of the global TBM map alongside Türkiye, Iran, North Korea, and South Korea.

The first-generation derivative will most plausibly leverage the AVTM (Aero Vector Tactical Missile) line developed by Avibras across the past decade. Production timelines and unit costs were not disclosed.

Paraná Civil Police receives first Senator APC

The Civil Police of Paraná state took delivery of its first Senator APC, the Canadian-built armored personnel carrier. Vehicles will also be delivered to the Military and Penitentiary Police, with configurations adapted to each force’s operational needs.

Subnational adoption of armored mobility platforms by Brazilian state police continues a trend visible since 2020 and reflects the persistent erosion of the line between civil and military security responsibilities in the country’s most violent jurisdictions.

The operational axis tracked the closure of three exercises and a renewed pulse of irregular-armed-group drone violence in Colombia. The FAB closed Shield-Tinia 2026 at Anapolis on May 29 with the F-39E Gripen confirmed in full quick-reaction-alert role — the first time a domestically-assembled supersonic fighter has owned the central Brazilian airspace.

Salitre 2026 multinational planning advanced. Chile-Brazil patrol competition opened in Arica. In Colombia, an ELN drone strike in the Catatumbo killed one soldier and wounded seven, sustaining the unbroken 1.5-day-per-attack tempo against the country’s security forces.

Shield-Tinia 2026 closes at Anapolis with F-39E Gripen in confirmed QRA role

The Brazilian Air Force closed its largest joint exercise of the year at the Anapolis air base in Goiás on May 29. The ESCUDO-TÍNIA 2026 cycle, which ran from May 11, brought together aircraft from the Army, Navy, and Air Force — F-39 Gripen, A-1M, A-29 Super Tucano, F-5M, E-99, KC-390 Millennium, and C-105 Amazonas — operating alongside ground and naval components.

The F-39 Gripen made its debut in the operational training programme. The selection of Anapolis as venue confirms the base’s full operational status for the new fighter, retooled to host the F-39 fleet and now Brazil’s primary alert station for central-west and Federal District airspace.

The Gripen Anapolis cycle was the first major exercise Brazil staged outside its southern fighter bases, and it landed precisely as neighbouring Colombia prepares its first payments on the $4.3 billion order for 17 Gripen E/F aircraft signed in November 2025 with deliveries scheduled 2026–2032.

The signaling is deliberate. Brazilian-assembled Gripens flying QRA missions from a base configured for the role, in a national exercise framework integrated with army anti-aircraft means, is the strongest endorsement Saab and Embraer can deliver to a paying foreign customer.

Catatumbo drone strike kills soldier — 500-attack milestone reached

A drone-delivered explosive attack attributed to the ELN killed one soldier and wounded seven during military operations in the Catatumbo region of Norte de Santander on Sunday, May 24. The strike is the second fatal drone incident against the Colombian armed forces in 2026 covered by the Defense Monitor — the Cauca attack reported in Issue #11 killed one officer and wounded six on May 19–20.

According to specialist tracking cited by Infodefense, the country has now sustained 500 drone attacks since 2024, with at least 915 grenades adapted to unmanned platforms deployed. The toll: 436 members of the security forces wounded, 24 soldiers killed, one Marine Corps infante killed, and 28 police officers killed.

The frequency, according to Colombian Army figures, is now one drone attack every 1.5 days. The Escudo Nacional Antidrones contract — opened by Presidential order in December 2025 — was meant to award before the May 31 first-round election.

As of the period close, no award has been confirmed. The technological trend is also worsening: the February ELN strike against the San Jorge garrison in Saravena used fiber-optic-guided drones for the first time, defeating Colombian electronic-warfare countermeasures. Specialist Camilo Mendoza, cited by InfoDefense, forecasts that within four months irregular groups will operate larger payloads in saturating swarms.

Daga Atlántica SOF exercise continues; Army commemorates 216th anniversary

The Argentine Armed Forces continued the Combined Special Operations Forces exercise Daga Atlántica (Atlantic Dagger) through the week, the bilateral framework with U.S. Special Operations Command South that has cycled annually since 2024.

The exercise provides the Command de Operations Especiales de la Marina Argentina, the Compañía de Commands 601 and 602, and the FAA’s Grupo Aéreo de Operations Especiales with sustained interoperability training and South Atlantic-relevant tactical scenarios.

Separately, the Ejército Argentino commemorated its 216th anniversary on Friday, May 29, with a ceremony at the Colegio Militar de la Nación in El Palomar, presided over by chief Teniente General Oscar Santiago Zarich.

Patrullas de Infantería 2026 opens in Arica with Brazilian delegation

The annual Competencia de Patrullas de Infantería 2026, organized by the Chilean Army’s Command de Operations Terrestres and executed by the 1ª Brigada Acorazada Coraceros, opened in Arica with a Brazilian Army delegation participating alongside Chilean teams.

The event commemorates the Asalto y Toma del Morro de Arica and Day of the Glories of the Infantry Arm of the Chilean Army. Brazilian participation continues the deepening of Brazil-Chile ground-forces interoperability that has accelerated under the Kast administration’s Defense Ministry.

Fuerza Air Force Uruguaya advanced flight squadron deploys to Paysandú

The Escuadrón de Vuelo Avanzado of the Fuerza Air Force Uruguaya conducted an operational and training deployment at Paysandú International Airport between May 26 and May 29, conducting tactical instruction and proficiency activities.

The deployment is consistent with the broader FAU operational rhythm that has accompanied the institution’s incremental modernization, including the Super Tucano fleet acquired under the Lacalle Pou government and the FAU’s growing relationship with U.S. SOUTHCOM training pipelines.

Salitre 2026 final planning conference completes

Representatives of the Fuerza Air Force de Chile and the air forces of Argentina, Brazil, Colombia, the United States and Paraguay closed Salitre 2026 planning during the period, with execution scheduled at Antofagasta from June 28 to July 12.

The 2022 edition featured A-4AR and IA-63 Pampa III from Argentina; F-5EM and KC-390 from Brazil; and A-36 Toqui, A-29 Super Tucano, F-16 Block 50, F-16 MLU, F-5 Tigre III, MH-60M, Bell 412EP, KC-130R, KC-135E, and E-3D Sentry from Chile.

The 2026 platform mix has not been disclosed, but Brazilian F-39E participation is the central operational question — confirmation would put the new fighter into its first multinational coalition exercise.

The policy axis dominated the issue. Bolivia’s Congress dismantled the 2020 legal architecture that constrained presidential use of the armed forces in domestic protests — a structural pivot in civil-military relations whose closest precedent is the 2019 transitional moment under Áñez.

Venezuela hosted a sitting SOUTHCOM commander inside the U.S. Embassy compound, with two Marine MV-22B Ospreys overflying Caracas residential districts; days later, María Corina Machado issued the “Manifiesto de Panamá” formally proposing direct negotiation with the Rodríguez interim government and a U.S.-monitored electoral process. Two posture pivots that together redraw the Andean political-military map.

SOUTHCOM commander lands in Caracas — second official visit to Venezuela in 2026

General Francis L. Donovan, USMC, the commander of U.S. Southern Command and the officer responsible for the January 3 operation that captured Nicolas Maduro, arrived in Caracas on Saturday, May 23, aboard two MV-22B Ospreys of the 22nd Marine Expeditionary Unit.

The aircraft overflew the southeastern suburbs of the capital — Valle Arriba and adjacent residential zones — before landing at the U.S. Embassy compound. According to the Venezuelan Foreign Ministry, Caracas had authorized the operation in advance as “a simulacrum of evacuation for medical or catastrophic contingencies, as part of regular protocols of diplomatic security.”

SOUTHCOM described the visit as “his second official visit to the country,” including bilateral discussions with senior interim-government leaders, meetings with U.S. Embassy leadership, and observation of “a joint force military response exercise.”

The military analytic reading is unambiguous. Colonel (ret.) Isidro Echtan Pérez Villalobos, cited by Infobae, characterized the operation as situated “within the doctrinal frame of Operation Southern Spear,” and warned that it “could be interpreted as an attempt to normalize the operational presence of the United States military in Venezuelan territory, and eventually, as the preamble to future U.S. military bases on Venezuelan soil.”

Donovan’s first Caracas visit, earlier in 2026, was a closed protocol event. This one was photographed by Venezuelan civilians from residential balconies and amplified across both Venezuelan and U.S. outlets within hours.

The signalling is to multiple audiences simultaneously: the Rodríguez government (a reminder of the operational reach that captured her predecessor), the Venezuelan opposition (a confirmation of the Trump administration’s investment in transition architecture), Havana (a demonstration of the SOUTHCOM toolkit in the basin), and the U.S. domestic audience (a defense-policy statement framed in operational rather than diplomatic register).

Machado issues “Manifiesto de Panamá” — proposes direct negotiation with Rodríguez government

From Panama on Thursday, May 28, opposition leader María Corina Machado issued the “Manifiesto de Panamá,” a formal political document calling for “serious, firm, and responsible political negotiation with the interim regime to restore democracy in Venezuela.”

The manifesto was co-signed by Edmundo González Urrutia and supported by the broader Command con Venezuela structure. Machado defined the negotiation’s central purpose as “the realization of a free, transparent, and sovereign presidential election.”

She formally requested the accompaniment of the United States to anchor the process, and confirmed her own candidacy in “free and fair elections,” declaring “the departure of Rodríguez is not in doubt.”

The political-military significance is that the Machado-Rodríguez configuration Issue #10 described as antagonistic has, after five months, produced an opposition framework explicitly oriented toward direct negotiation with the interim presidency.

The implicit reading — that Machado was excluded from the original U.S.-Qatari transition track (Issue #10) but has now constructed a parallel architecture with U.S. blessing — is consistent with the Donovan Caracas visit five days earlier. Secretary of State Rubio’s “we don’t want to go too fast” framing (Issue #10) is now flanked by a Machado-mediated proposal that compresses the timeline toward elections under Machado’s own preferred terms. The chavista bureaucracy and security apparatus around Rodríguez have not formally responded.

Ley 1732 abrogates Ley 1341 — Paz unlocks legal architecture for military intervention

The Bolivian Senate approved on May 24 the abrogation of Ley 1341 of October 2020 — the “Ley Eva Copa,” which had limited military participation in domestic protests to Police-overwhelmed scenarios within 60-day caps.

The Cámara de Diputados approved on May 26 in a virtual session of more than five hours with 117 deputies present, by more than two-thirds. President Rodrigo Paz promulgated Ley 1732 hours later, on May 27. The new law does not automatically declare a state of exception, but removes the statutory ceiling on presidential discretion to deploy the Fuerzas Armadas inside Bolivian territory against social mobilization.

The trigger context is the protest cycle covered in Issue #11. The blockade map expanded across the week: governor Jesús Egüez Rivero declared Beni in humanitarian emergency on May 25 over food, medicine and fuel shortages; Pando governor Claudia Paiva declared her department in emergency on May 30 over electricity and fuel supply risks.

Miners attempted to take the Parotani bridge in Quillacollo on May 25, producing the first significant police-military dispersal of the cycle. Cocaleros surrounded the Ninth Army Division in Chapare on May 25 amid rumors of imminent Morales arrest. Bolivia’s country-risk indicator now ranks second in Latin America, behind Venezuela.

The political-military reading is that the Paz government has chosen institutional escalation over negotiation, with the structural risk that the abrogated Ley Eva Copa — drafted under the post-Áñez Congress to constrain executive abuse of the FFAA — was the very legal architecture designed to prevent the next cycle of military overreach.

Trump on Cuba: island is “about to fall” — administration calls strategy “accelerationism”

President Trump told reporters during the week that Cuba is “about to fall” because the island no longer receives Venezuelan oil or remittances since the January 3 capture of Maduro.

Politico reported May 29 that the Caribbean concentration of U.S. military forces is now the largest outside the Middle East, including the USS Nimitz CSG (covered in Issue #11), additional guided-missile destroyers, and fighter assets repositioned around Florida.

A White House adviser quoted by Axios described the strategy as “accelerationism” — combining the existing trade blockade with newly-imposed oil-supply restrictions producing rolling blackouts and humanitarian compression.

CSIS analyst Mark Cancian, also cited by Politico, said the Nimitz is “primarily there for intimidation, though it could be used in a military operation if needed.” No invasion is currently planned or imminent, according to multiple administration sources, but the Pentagon has developed contingency options.

The pressure architecture’s regional implications are immediate. The Dominican Republic’s October-31 SOUTHCOM access extension (Issue #10) and Donovan’s Caracas visit form a single Caribbean operational geometry.

Russia and China — Cuba’s principal external supports — registered no LATAM defense activity during the period (see §04), constraining Havana’s response options.

The Cuban Foreign Ministry has condemned the Castro indictment as a “despicable accusation” and accused Washington of using it as a pretext for possible military action, but has not announced any operational counter-measure beyond rhetorical condemnation.

The Great Power Tracker reflects the most asymmetric week of 2026 to date. The United States executed a high-density combination of carrier-strike-group repositioning, SOUTHCOM commander presence in Caracas, expanded basing posture in the Caribbean, and “accelerationism” rhetoric toward Cuba.

South Korea returned to the visible tier with confirmed FA-50 and K2 marketing into the Peruvian and Colombian replacement competitions. China and Russia produced no reportable LATAM activity for the third consecutive issue, an unusual quiet period that is itself the data point.
