(DEFENCE SECURITY ASIA) — Southeast Asia’s missile balance is changing as Vietnam, Indonesia and Myanmar emerge as the region’s only confirmed operators of dedicated ballistic missiles, challenging ASEAN’s preference for defensive, maritime-focused force structures.

Their inventories remain modest beside China, India or North Korea, yet limited arsenals create counter-strike options, complicate adversary planning and compress decision timelines across an increasingly contested Indo-Pacific environment.

Vietnam combines upgraded Soviet-origin Scuds with an evolving coastal-strike architecture, Indonesia fields Türkiye’s precision-guided KHAN system, while Myanmar maintains an opaque mixture of North Korean, Chinese and potentially indigenous missile capabilities.

This divergence matters because ballistic missiles deliver warheads rapidly against fixed command posts, airfields, radars, logistics hubs and infrastructure, potentially disrupting force generation before conventional naval or air assets enter combat.

Most ASEAN militaries still emphasise cruise missiles, coastal defence batteries and guided multiple-launch rocket systems, reflecting political sensitivity surrounding offensive weapons and their demanding command, surveillance and sustainment requirements.

However, South China Sea tensions, sharpening great-power competition and the collapse of the Intermediate-Range Nuclear Forces Treaty have normalised land-based long-range strike as an increasingly legitimate instrument for strategically exposed middle powers.

The regional shift extends beyond three inventories, representing migration from platform-centred deterrence toward distributed anti-access and area-denial networks linking mobile launchers, sensors, communications, precision weapons and hardened battlefield logistics.

Vietnam possesses the most mature maritime-continental strike architecture, Indonesia has introduced Southeast Asia’s first modern precision tactical ballistic missile, while Myanmar’s readiness, accuracy, inventory and doctrine remain largely unverified.

These asymmetries produce different strategic effects: Hanoi can threaten broad landward and maritime approaches, Jakarta can protect critical infrastructure through accurate tactical fires, and Naypyidaw can exploit uncertainty as deterrent signalling.

No confirmed ballistic-missile inventories exist elsewhere in ASEAN, although the Philippines and Vietnam are acquiring BrahMos, Singapore is integrating Blue Spear, and several regional forces operate capable guided rocket artillery.

Consequently, Southeast Asia is not experiencing a uniform ballistic-missile race, but a broader competition for survivable long-range precision strike that could strengthen deterrence while increasing escalation risks, misinterpretation and intra-ASEAN suspicion.

The decisive strategic question is whether doctrine, intelligence, targeting, command resilience and logistics can transform small inventories into credible operational forces without destabilising neighbouring security calculations during an escalating regional crisis.

Vietnam’s Upgraded Scuds Create a Maritime-Continental Deterrence Dilemma

Vietnam retains Southeast Asia’s longest-standing ballistic-missile capability, having acquired Soviet R-17E Scud-B systems around 1981 and sustained them through four decades of maintenance, modification, organisational reform and technical assistance.

The original single-stage, liquid-fuel missile carries an approximately 900-to-1,000-kilogram high-explosive warhead, reaches Mach 5 and was designed to attack fixed, unhardened targets across a published range of 50 to 300 kilometres.

Its MAZ-543 transporter-erector-launcher provides road mobility, but a roughly one-hour deployment-to-launch cycle and liquid-propellant support burden create detectable logistics signatures, greater preparation vulnerability and slower reaction than modern solid-fuel alternatives.

Vietnamese upgrades reportedly extended Scud-B range from 300 to 500 kilometres, while firings associated with 550-to-700-kilometre performance remain publicly unresolved, making the force’s maximum operational reach, payload trade-offs and reliability uncertain.

Domestic oxidiser production reduces foreign dependence and strengthens wartime endurance, while replacement components and guidance improvements could increase availability, although unofficial accuracy claims approaching 50-to-100-metre circular error remain unverified.

The established 490th Missile Brigade in Hai Phong anchors northeastern coverage, whereas relocation of the reactivated 380th Missile Brigade toward Dak Lak places mobile strike assets near the geographic centre of the Indochinese peninsula.

That repositioning creates a maritime-continental dilemma because launchers in mountainous central terrain could retain eastern access toward South China Sea approaches while extending westward coverage across Cambodia, Laos and parts of Thailand.

Vietnam’s August 2025 Artillery-Missile Command restructuring further signals institutional commitment to coordinated long-range fires, with theatre formations envisioned around surface-to-surface missiles, long-range anti-ship batteries and mixed artillery rather than isolated legacy units.

Scuds now complement Bastion-P coastal missiles, the displayed Truong Son shore-based system and a roughly US$629 million BrahMos acquisition, producing layered options across different trajectories, speeds, guidance methods, warheads and target categories.

Although ageing Scuds remain less precise and heavier than newer missiles, their upgraded reach, mobile basing and organisational continuity retain utility by forcing adversaries to disperse nodes, reinforce defences and complicate planning.

Indonesia’s KHAN Introduces Precision Ballistic Strike to Maritime Southeast Asia

Indonesia entered the modern regional ballistic-missile club with Roketsan’s KHAN, locally designated ITBM-600, after becoming the Turkish Bora export variant’s first foreign customer through an acquisition signed during Indo Defence 2022.

Fielded from 2025, the solid-fuel short-range ballistic missile combines an 80-to-280-kilometre envelope, Mach 5-plus velocity and a 470-kilogram high-explosive or fragmentation warhead for rapid attacks against fixed high-value targets.

GPS and GLONASS-aided inertial navigation reportedly enables accuracy within ten metres circular error probable, while an inertial-only mode, anti-jamming provisions and terminal manoeuvring improve resilience when satellite navigation becomes contested or denied.

Mounted on highly mobile Tatra 8×8 vehicles, KHAN supports shoot-and-scoot tactics that shorten exposure after launch, reduce counter-battery vulnerability and distribute Indonesia’s precision-strike capacity across difficult terrain and a fragmented archipelagic geography.

The first batch reached East Kalimantan during 2025 and appeared with the 18th Field Artillery Battalion near Tenggarong, while the second batch’s delivery, integration and handover remained incompletely documented by August 2026.

Reported plans envision four firing batteries and a headquarters battery under one artillery battalion, but missile quantities, reload depth, launcher availability, sensor integration and wartime sortie generation have not been disclosed.

Basing near Nusantara aligns KHAN with Indonesia’s large-island defence concept, allowing accurate fires around critical infrastructure, maritime approaches and border areas while giving the army an organic capability previously absent beyond roughly 200 kilometres.

Current East Kalimantan positioning cannot reach the Natuna Islands or distant Spratly features, and KHAN’s land-attack profile cannot substitute for manoeuvring anti-ship weapons required to impose credible maritime denial against hostile surface combatants.

Its present footprint nevertheless intersects strategic sensitivities around Ambalat and nearby Malaysian territory if launchers reposition, demonstrating how tactical range, road mobility and uncertain deployment patterns can generate political effects exceeding actual operational intentions.

Alongside Astros II rockets, CAESAR artillery and prospective missile cooperation, KHAN provides a bridge toward integrated fires, supplier diversification and domestic production, but effectiveness depends upon targeting networks and logistics.

Myanmar’s Opaque Arsenal Turns Uncertainty into Strategic Leverage

Myanmar’s ballistic-missile programme remains Southeast Asia’s least transparent, with no recent official displays, confirmed inventory figures or demonstrated combat employment, forcing assessments to rely upon imagery, defector testimony, procurement evidence and industrial activity.

Reported holdings include the roughly 300-kilometre Hwasong-5, the 500-to-700-kilometre Hwasong-6 and China’s modular SY-400 or BP-12A family, whose ballistic variant may reach between 150 and 400 kilometres depending upon payload.

North Korean technology transfer reportedly began around 2008, specialists remained involved into the following decade, and missile-related materials were intercepted in 2014, indicating a sustained but deliberately concealed effort rather than transparent force development.

Myanmar reportedly received the SY-400 around 2020, providing a modular launcher capable of firing guided 300-millimetre rockets or BP-12A tactical ballistic missiles, although operational readiness, crew proficiency, stockpile depth and accuracy remain unknown.

A possible Chinese M-11 acquisition from the 1990s remains unconfirmed, while reports describing additional Hwasong variants or local modifications lack official corroboration and must be separated from demonstrable equipment deliveries or verified testing activity.

Missile development centres upon Directorate of Defence Industries facilities, particularly Ka Pa Sa 23 in Magway Region, where reported projects include a 130-kilometre guided weapon and CK-21 ballistic missile targeting 700-kilometre performance.

Local production of raw materials could reduce vulnerability to sanctions and interdiction, yet dependence upon imported specialised components would constrain production rates, quality control, guidance reliability and wartime replenishment under pressure.

No widely documented ballistic-missile flight tests or combat launches occurred during 2025–2026, while Myanmar’s internal war relied chiefly upon aircraft, conventional artillery, multiple-launch rockets, drones, bombs and improvised aerial platforms.

That operational pattern suggests ballistic missiles, if serviceable, are reserved for deterrence, prestige or attacks against exceptional fixed targets rather than routine counterinsurgency, where their cost, scarcity and strategic visibility would offer limited advantage.

Opacity provides leverage by complicating neighbouring defence planning and intervention calculations, but absent verified readiness, precision or command arrangements, uncertainty cannot be equated with a mature, survivable or credible missile force.

Missile Logistics and Force Posture Will Decide Combat Credibility

Ballistic-missile ownership does not guarantee meaningful deterrence because combat credibility depends upon trained crews, protected command networks, accurate target data, mobile launch discipline, reload availability, maintenance capacity and resilient fuel or propellant supply chains.

Vietnam’s liquid-fuel Scuds impose the heaviest logistical burden, requiring longer preparation and specialised handling, whereas Indonesia’s solid-fuel KHAN offers faster response, simpler field storage and reduced exposure during deployment, firing and displacement cycles.

However, KHAN’s superior precision cannot compensate for insufficient intelligence, surveillance and reconnaissance because coordinates for relocatable radars, mobile command posts or dispersed logistics must remain current throughout detection, approval, launch and missile flight.

Vietnam’s reach creates broader target coverage, but Scud-era inertial accuracy limits efficient attacks against hardened point targets unless modernised guidance performs as claimed, potentially requiring multiple missiles and rapidly consuming a small wartime inventory.

Myanmar’s principal constraint is uncertainty across every operational layer, from launcher numbers and missile condition to communications security and crew proficiency, making its theoretical ranges poor indicators of repeatable combat output or campaign-level effect.

Road-mobile launchers increase survivability only when supported by concealment areas, route reconnaissance, decoys, emissions control and dispersed reload teams, because persistent aerial surveillance can identify predictable bases, movement corridors and preparation signatures.

Pre-emptive pressure would therefore focus upon storage depots, communications nodes, transporter maintenance facilities, meteorological support and fuel infrastructure, demonstrating why the missile ecosystem is more strategically important than publicly photographed launch vehicles alone.

Air and missile defence responses differ: Scud-type ballistic arcs demand early warning and interception coverage, KHAN’s speed and terminal manoeuvres shorten engagement windows, while uncertain Myanmar profiles complicate sensor allocation and interceptor planning.

Small arsenals may still influence adversary behaviour by forcing dispersal, hardening and redundancy expenditures, allowing relatively inexpensive mobile batteries to impose disproportionate defensive costs even without achieving decisive destructive effects during conflict.

Conversely, limited reloads and vulnerable support networks could turn initial salvos into temporary signalling rather than sustained strike campaigns, making transparent exercises, validated command procedures and industrial replenishment decisive measures of genuine operational maturity.

ASEAN’s Long-Range Strike Shift Raises Deterrence and Escalation Risks

Southeast Asia’s missile competition extends beyond ballistic systems, encompassing BrahMos, Blue Spear, Bastion-P, Truong Son, guided multiple-launch rockets and prospective Turkish or Chinese weapons that collectively redistribute regional combat power toward land-based precision fires.

This transition favours states unable to match larger navies platform for platform, because dispersed coastal and land-attack batteries can threaten concentrated forces, ports, airfields and command infrastructure while remaining difficult to locate and neutralise.

For Vietnam, layered Scud, BrahMos and coastal-defence capabilities complicate Chinese operational planning without replicating China’s fleet size, supporting national autonomy through asymmetric denial while preserving strategic ambiguity over continental and maritime targeting priorities.

Indonesia’s KHAN is less directly relevant to China from its current position, instead signalling protection of Nusantara, large-island defence and limited border-area strike options while separate anti-ship capabilities address the archipelago’s maritime denial requirement.

Myanmar’s missiles affect Bangladesh, Thailand and India, with their potential reach offering insurance against external intervention and prestige for the military government, although civil-war demands and unverified readiness limit confident assessments of deterrent value.

Regional supplier diversification reinforces ASEAN’s alignment-without-alliance tradition, with Türkiye, India, China, Russia and other partners offering different missile technologies, financing structures and industrial pathways without requiring formal security alignment with one great power.

The post-2019 strategic environment has reduced political inhibition surrounding ground-launched missiles, while battlefield lessons from Ukraine highlight how mobile precision fires, distributed logistics and sustained munitions production can shape campaigns against technologically superior opponents.

Yet increased reach compresses warning time and magnifies ambiguity because launches intended as limited conventional signalling could be misread as attacks upon leadership, air bases or strategic infrastructure, accelerating retaliation before intent becomes clear.

ASEAN faces a stability challenge rather than an immediate region-wide arms race: inventories remain comparatively small, but opaque deployments, uncertain doctrines and overlapping coverage can generate suspicion disproportionate to actual missile numbers or accuracy.

Vietnam, Indonesia and Myanmar have introduced distinct ballistic-missile models—legacy strategic reach, modern tactical precision and opaque deterrence—whose combined effect is to redraw Southeast Asia’s battlespace around mobility, logistics, survivability and long-range strike.
