IN Brief:
- The US Army has established a Basic Ordering Agreement covering Elsight’s Halo communications technology.
- Halo bonds cellular, satellite, and RF links to support resilient beyond-visual-line-of-sight connectivity for uncrewed systems.
- The agreement follows Halo’s Blue UAS listing but does not guarantee Army orders, quantities, or delivery volumes.
Elsight has secured a Basic Ordering Agreement with the US Army covering its Halo communications technology, creating a contractual framework through which Army organisations can place future orders for connectivity equipment used on uncrewed systems.
The agreement does not contain a disclosed purchase quantity, minimum value, or guaranteed volume. A Basic Ordering Agreement establishes agreed terms and procedures that can support later orders, so the commercial outcome will depend on whether individual Army customers issue funded requirements against it.
Halo is designed to maintain beyond-visual-line-of-sight communications by combining several available network paths rather than relying on one link. Elsight says the system can bond cellular, satellite, and radio-frequency connections and move traffic between them as conditions change, giving an uncrewed platform alternatives when one service becomes degraded or unavailable.
The company positions the technology for uncrewed air, land, and maritime systems. That gives the same communications approach potential use across platforms with very different payload, antenna, power, and operating constraints, provided the underlying integration can be adapted to each vehicle.
Connectivity is one of the practical limits on uncrewed-system performance. An aircraft may have sufficient endurance to travel far beyond the local operator, but sensor and mission capability is reduced if command, telemetry, or payload data cannot be moved reliably once it leaves normal radio coverage. Ground and maritime vehicles face similar problems around terrain, buildings, infrastructure, and changing propagation conditions.
Using several networks can improve resilience, but it also creates an engineering problem above the individual modem. Cellular, satellite, and tactical RF services have different latency, bandwidth, cost, coverage, and security characteristics. A bonding system has to decide how traffic is distributed, when to move sessions between links, and how to maintain the applications running above them while network quality changes.
The task becomes harder in contested environments because a lost connection may result from deliberate interference rather than ordinary coverage. Multi-link communications cannot make every path immune to jamming, but they can reduce dependence on one frequency, operator, or infrastructure type and allow a platform to retain another route when one service is denied.
Physical integration remains important. Terminals, processors, antennas, and cabling consume payload and electrical power, while antenna positioning can affect communications performance and interfere with navigation, sensors, or other radio-frequency equipment. Those constraints become more severe on smaller uncrewed aircraft where every additional component competes for mass and energy.
Halo is intended to sit between the vehicle and several underlying networks, allowing the platform to use different communications services without redesigning the entire mission system each time a link changes. That can reduce integration work across fleets that operate in several regions or need to combine commercial and dedicated communications infrastructure.
The Army agreement follows Halo’s addition to the US Government Blue UAS List earlier in 2026. Elsight said that listing confirmed compliance with relevant supply-chain, cybersecurity, and data-integrity requirements and created a more direct procurement route for government programmes using vetted uncrewed-system technology.
Blue UAS status and a BOA perform different functions. The listing addresses whether a component has passed a government vetting process for approved use, while the BOA establishes contractual terms that can be used if an Army organisation decides to buy it. Neither is equivalent to a fleet-wide procurement decision.
That distinction matters because supplier announcements around government contract vehicles can imply more committed demand than exists. The 2 September agreement gives Army customers a mechanism to purchase Halo; it does not state how many systems the Army intends to buy, which platforms would receive them, or when deliveries might begin.
Elsight has also been progressing through US defence evaluation activity associated with the Defense Innovation Unit. The company has said Halo moved through advanced fielding and testing before reaching the Blue UAS route, giving the system an established evaluation history ahead of the new Army contracting framework.
The commercial opportunity therefore depends on conversion. A BOA can reduce the administrative delay around individual purchases, particularly when several units or programme offices need access to the same technology, but funded orders still have to follow.
For Army users, the attraction is a communications layer able to exploit several networks without tying an uncrewed platform to one carrier or transmission method. For Elsight, the next useful milestone is more concrete: an order identifying quantities, platform applications, and delivery dates.
Until that occurs, the 2 September agreement is procurement infrastructure rather than booked volume. It places Halo on an Army purchasing pathway after the product cleared an important government vetting route, but the scale of operational adoption remains to be demonstrated.
