Turkey Reportedly Nears Deal to Supply Hisar-O+ and Siper Air Defence System to Bangladesh

(DEFENCE SECURITY ASIA) — In a significant shift in South Asia’s strategic defence calculus, Turkey is reportedly preparing to supply Bangladesh with its indigenously developed Hisar-O+ medium-range and Siper long-range surface-to-air missile (SAM) systems.

The move, emerging from high-level talks in Ankara and Dhaka, signals a decisive step in Bangladesh’s ambition to modernize its national air defence architecture while positioning Turkey as a new and increasingly influential arms supplier in the region.

The proposed transfer of these advanced air defence systems underscores both nations’ deepening military ties and Ankara’s determination to expand its defence export footprint beyond traditional markets in the Middle East and North Africa.

For Bangladesh, a country long reliant on a patchwork of Chinese, Russian, and European air defence assets, the acquisition of the Turkish Hisar-O+ and Siper systems would represent a generational leap in capability — enabling the creation of a multi-layered defensive shield capable of detecting, tracking, and intercepting a wide spectrum of airborne threats.

The deal, still in its advanced negotiation phase, is believed to include not only missile systems but also radar, command, and control infrastructure, as well as training and maintenance packages essential for long-term operational sustainability.

While final delivery schedules remain undisclosed, sources close to the discussions suggest that the first Hisar-O+ batteries could arrive as early as late 2026, followed by Siper systems for Bangladesh’s Air Force by 2027 or 2028.

This development marks an inflection point for both Dhaka and Ankara.

For Bangladesh, it represents a long-awaited move toward a robust, indigenous-capable air defence network — an essential deterrent in an increasingly volatile Indo-Pacific security environment marked by rapid technological militarization and regional arms races.

For Turkey, it reinforces its role as a rising global defence exporter capable of delivering affordable, ITAR-free systems that compete with Russian and Western equivalents without political restrictions.

Deepening Turkey-Bangladesh Defence Relations

Over the past decade, Turkey and Bangladesh have quietly cultivated a multi-dimensional defence relationship rooted in shared strategic interests, Islamic cultural affinity, and mutual goals of self-reliant defence modernization.

Ankara’s emergence as a reliable supplier for Dhaka follows years of consistent engagement, including training exchanges, industrial cooperation, and joint exploration of unmanned and missile technologies.

Bangladesh, under its Forces Goal 2030 modernization plan, has sought to diversify its defence partnerships to mitigate overreliance on Chinese and Russian systems while ensuring interoperability with Western equipment.

Turkey’s offering of the Hisar-O+ and Siper systems aligns perfectly with this ambition.

In October 2025, Bangladesh Air Force Chief Air Chief Marshal Hasan Mahmood Khan made a high-profile visit to Turkey, where he toured Turkish Aerospace Industries (TAI), Aselsan, and Roketsan — the key industrial players behind Turkey’s growing missile defence ecosystem.

During the visit, Khan discussed multiple acquisition programs, including Baykar’s Bayraktar TB2 and Akinci drones, alongside the Hisar and Siper systems.

These discussions signal Bangladesh’s broader intent to integrate a layered air defence system that combines ground-based interceptors, UAV reconnaissance, and command integration under a unified national network.

According to defence sources in Dhaka, Bangladesh is particularly interested in Turkey’s “turnkey” approach — offering complete operational ecosystems that include radars, communication links, and command posts, rather than isolated platforms.

This model mirrors Turkey’s own “Steel Dome” initiative, which integrates multi-tier missile defences from short-range to long-range systems under a common command structure.

The Hisar-O+: Medium-Range Shield for Bangladesh Army

At the tactical level, the Hisar-O+ system represents the medium-range backbone of Turkey’s indigenous air defence family, capable of neutralizing fast-moving aerial threats in complex battlefield conditions.

Developed by Aselsan and Roketsan, with research input from TÜBİTAK SAGE, the Hisar-O+ employs both active radar homing and imaging infrared guidance to ensure high accuracy under all-weather conditions.

Its vertical launch design allows 360-degree coverage, with engagement ranges exceeding 25 kilometers and intercept altitudes up to 15 kilometers.

Mobility is a core design principle — each launcher is mounted on an 8×8 tactical truck chassis, enabling rapid deployment across diverse terrains such as Bangladesh’s floodplains, border regions, and coastal zones.

The system is equipped with a 3D phased array search and track radar, fire control unit, and command vehicle, forming a complete autonomous battery capable of operating independently or networked into a broader national grid.

Turkey’s Defence Industries Agency (SSB) finalized a $1.5 billion contract for Hisar-O+ mass production in 2023, cementing its maturity and export readiness.

Operational tests demonstrated successful intercepts against multiple target types, including cruise missiles, UAVs, and fast jets, validating its multi-threat engagement capability.

For Bangladesh, Hisar-O+ will likely be deployed by the Bangladesh Army’s Air Defence Artillery, providing point and area defence for strategic installations, critical infrastructure, and forward bases.

Analysts believe these systems could be stationed along the western and southern sectors, protecting Dhaka, Chittagong, and the Cox’s Bazar region — areas of increasing economic and military significance.

The Siper: Bangladesh’s Future Strategic Air Defence Umbrella

At the strategic level, the Siper long-range system is Turkey’s answer to the Patriot and S-400 — a domestically developed system intended to provide high-altitude, extended-range interception against aircraft, drones, and tactical ballistic missiles.

Developed collaboratively by Aselsan, Roketsan, and TÜBİTAK SAGE, the Siper system began entering Turkish service in 2024 after a decade of development and successful live-fire testing.

Its engagement envelope exceeds 100 kilometers in range and 20 kilometers in altitude, positioning it as one of the most capable non-Western long-range SAMs available on the export market.

The missile employs an advanced dual-pulse solid rocket motor, ensuring sustained acceleration during mid-course flight and improved terminal maneuverability.

Siper’s seeker suite includes active radar homing and imaging infrared modules, providing redundancy and improved resistance against electronic countermeasures.

Each Siper battery integrates multi-function phased array radars, a command and control center, and multiple vertical launchers capable of firing various missile variants — including future extended-range and ballistic defence versions under development.

Bangladesh Air Force planners view Siper as the cornerstone of a national “strategic shield,” intended to complement shorter-range assets like the FM-90 and Hisar-O+.

Together, these systems would form Bangladesh’s first-ever integrated, multi-layered air defence network capable of detecting and intercepting modern threats at multiple altitudes and ranges.

Turkish engineers have also offered modular integration options, allowing Siper batteries to operate either autonomously or through Bangladesh’s national radar grid, potentially linked to Chinese, Swiss, or locally developed sensors.

Regional and Strategic Implications

The implications of this planned acquisition extend far beyond the technical domain.

Regionally, the Hisar-O+ and Siper deal could reshape South Asia’s balance of air defence capabilities, traditionally dominated by India’s Russian-supplied S-400 Triumf systems.

While Bangladesh’s purchase would not match the S-400’s reach, it would still represent a credible deterrent and complicate regional air planning, particularly near sensitive border zones.

For India, which maintains strategic watch over the Bay of Bengal and eastern frontier, Bangladesh’s acquisition of Turkish air defence technology may raise concerns about reduced air superiority in its eastern theatre.

New Delhi’s defence analysts have already voiced caution on social media and think tank circles, suggesting that Dhaka’s move could “alter the tactical calculus” in potential cross-border or airspace disputes.

In contrast, for Myanmar, which has recently upgraded its air defences with Chinese KS-1M and Russian Pantsir systems, the Turkish systems in Bangladesh may compel a new round of modernization to maintain parity.

This acquisition also carries implications for China, currently Bangladesh’s largest arms supplier.

Ankara’s entry into the Bangladeshi defence market represents a diversification strategy that may gradually dilute Beijing’s near-monopoly over Dhaka’s military procurement pipeline.

The partnership underscores Bangladesh’s pragmatic approach to defence diplomacy — balancing relations between China, Russia, the West, and now Turkey to maximize capability while avoiding dependency.

For Turkey, this deal strengthens its ambition to become a top ten global defence exporter by 2030, following successful exports of drones, armoured vehicles, and missile systems to countries such as Azerbaijan, Pakistan, and Saudi Arabia.

Technology Transfer and Industrial Collaboration

One of the most consequential aspects of the deal could be its industrial dimension.

Turkey has indicated willingness to provide limited technology transfer and co-production opportunities to partner nations, particularly those with emerging defence industries.

Bangladesh’s nascent defence manufacturing ecosystem — centered around the Bangladesh Machine Tools Factory and the Bangladesh Ordnance Factories — could greatly benefit from such cooperation.

Joint assembly or component production agreements for the Hisar or Siper systems could seed the foundation for a new generation of local engineers and technicians.

Defence industry observers suggest that Dhaka may seek partial local assembly of launchers or radar subsystems, coupled with training programs hosted by Aselsan and Roketsan.

Such initiatives would complement Bangladesh’s broader national goal of reducing import dependency and developing a self-sustaining defence base under Forces Goal 2030.

However, the technical sophistication of the Siper system — particularly its radar and guidance units — may limit the extent of immediate technology transfer.

Instead, the collaboration could begin with maintenance, servicing, and logistical support, gradually expanding into component manufacturing as local expertise matures.

Operational Integration and Challenges

Integrating advanced missile defence systems into Bangladesh’s existing command structure presents both opportunities and challenges.

The country currently operates a heterogeneous mix of Chinese, Russian, and European air defence assets, each with distinct communication protocols and radar data formats.

Turkey’s systems, being NATO-standard, would require sophisticated data-link integration and network synchronization to ensure seamless interoperability.

Ankara is expected to assist with this process by providing command-and-control software interfaces and technical advisors during initial deployment.

Bangladesh’s terrain — characterized by low-lying plains, dense population zones, and high humidity — also poses environmental challenges that could impact radar performance and missile maintenance.

Turkey’s prior experience deploying similar systems in coastal and desert climates may help tailor operational configurations suitable for Bangladeshi conditions.

Furthermore, training remains a critical component.

The agreement reportedly includes extensive training modules for Bangladeshi officers and technicians, to be conducted at Turkish military academies and defence industrial facilities.

These programs would likely focus on system operation, radar interpretation, electronic warfare countermeasures, and battlefield integration.

Broader Geopolitical Context

This emerging defence partnership between Ankara and Dhaka also fits within Turkey’s larger foreign policy vision of expanding influence across the Muslim world through technology-driven defence cooperation.

Ankara has systematically leveraged its indigenous defence industry — encompassing drones, missile systems, and naval assets — as a diplomatic instrument for strategic outreach.

For Bangladesh, the alignment offers an opportunity to strengthen military ties with a Muslim-majority NATO member without being drawn into great-power rivalries.

Turkey’s ITAR-free systems provide Dhaka flexibility from Western export restrictions and sanctions risks, which often complicate arms purchases from the United States or Europe.

At the same time, Ankara’s growing reputation as a reliable defence partner may allow Bangladesh to access cutting-edge systems at competitive prices, a decisive factor for developing nations seeking value without sacrificing capability.

This cooperation also reinforces Ankara’s strategic ambition to establish a “defence corridor” connecting the Middle East, South Asia, and Southeast Asia, positioning Turkish systems as a preferred alternative to both Western and Chinese platforms in the developing world.

For Dhaka, the partnership with Turkey could also serve as a diplomatic bridge toward broader defence-industrial integration with NATO-standard technologies, paving the way for future collaborations in radar, command networks, and unmanned aerial warfare capabilities that align with its long-term Forces Goal 2030 objectives. — DEFENCE SECURITY ASIA
