How EW Has Changed Requirements for Reconnaissance UAVs in 2026

A successfully completed mission in 2026 is not only about capturing imagery — it is about penetrating dense EW environments without losing control. Modern requirements for reconnaissance UAVs include EW resilience, reliable communication links, and continuous improvement of performance characteristics to ensure stable control under critical conditions.

The ANT team constantly keeps a finger on the pulse, communicating daily with military personnel to improve reconnaissance UAVs.
In 2026, several key trends are already evident due to the widespread use of EW by both adversary and friendly forces.

How EW Is Changing Reconnaissance UAV Operations

Between 2025 and 2026, EW resilience has become a baseline requirement for Ukrainian-made UAVs. Previously, EW systems operated within relatively narrow, standardized frequency bands. Today, the adversary continuously expands the frequency spectrum to jam UAVs, including those operating on non-standard control channels. They dynamically adjust transmission power and employ increasingly sophisticated techniques to complicate detection of EW assets.

As a result, a reconnaissance UAV must not only be capable of flight — it must maintain stable operation under active electronic suppression.  Survivability has become a critical design parameter for successful mission execution. While EW systems were once used to detect and disrupt radio networks, they are now primarily targeting UAVs of various types.

Core Requirement: EW-Resilient Communications

In 2026, UAVs for the Armed Forces must be equipped with at least two independent communication links operating on different frequencies. While technically complex and costly to implement, losing a reconnaissance UAV to EW interference is far more expensive.

Communications remain the most vulnerable component of a UAV system. When the link is disrupted, the aircraft may deviate from its course, crash, or revert to return-to-home mode, resulting in the loss of both platform and mission data. During such events, the operator has no control and is forced to wait, losing valuable time.

ANT engineers improve UAVs as an integrated system

Resistance to electronic warfare is a system-level engineering challenge: communications, algorithms, antennas, and software solutions. It is not an optional feature, but a fundamental part of the design — one that is indispensable in modern warfare.

The MERCURY UAS was initially developed with a single communication channel. However, after field testing and operator feedback from multiple operational directions, it became clear that this was insufficient. A second, redundant, EW-resilient communication link became mandatory.

In 2026, the third iteration of the Ukrainian UAV architecture enables uninterrupted video transmission even under EW conditions. The primary link operates as a one-way downlink, and the secondary link employs wideband FHSS (frequency-hopping spread spectrum), making it extremely difficult or practically impossible to jam.

The only effective algorithm:

→ Deploy to the frontline and test UAS under real combat conditions
→ Collect feedback from military personnel and UAV operators regarding adversary EW systems
→ Immediately implement changes and enhance radio communication stability
→ Continuously improve technical characteristics: altitude, range, EW resistance

Feedback from Military Operators on MERCURY

❝ The mission was completed without failures. Under enemy EW suppression, control and communication remained stable, including when using map-based retasking

❝ The manufacturer’s specifications were confirmed during testing. The MERCURY UAS demonstrated high autonomy, stable communication links, and sufficient quality of reconnaissance data for operational use in combat conditions.

It is critical to validate declared performance characteristics in practice, as only testing under combat conditions can prevent operational failures and ensure the survivability of UAV systems deployed by the Armed Forces of Ukraine. In ANT’s development process, feedback is the most important source of improvement. We continuously explore new capabilities, attend professional exhibitions in Ukraine and abroad, and implement new approaches.

Enhancing Reconnaissance UAV Capability: MERCURY Case Study

◾️ Operational range of up to 20 km, enabling missions outside high-risk zones and reducing exposure to adversary EW.
◾️ High level of resistance to electronic warfare systems.
◾️ Pre-deployment validation against EW targeting control signals, video, and GNSS
◾️ It can continue flying in adverse weather conditions and in radio silence mode, which provides flexibility when performing tasks. Even in areas of active electronic warfare, it autonomously completes its mission and returns to base.

How UAV technical characteristics impact reconnaissance missions

The MERCURY UAS is equipped with two relatively EW-resistant communication links, enabling operation in environments where other UAVs cannot function even theoretically. In EW conditions, MERCURY maintains video transmission, enabling a broader mission set: fire correction and real-time reconnaissance.

Key Challenge of 2026: Friendly EW Interference

EW systems have evolved since the beginning of the Russian invasion.  Today, friendly EW significantly affects mission execution due to its widespread use in response to enemy systems. This significantly impacts communications, especially when EW systems are activated unexpectedly or without coordination. Navigation may be disrupted, and UAV control during takeoff and landing becomes more difficult.

While Ukrainian forces have learned to operate in enemy territory, coordination between friendly EW assets is not always consistent. UAV development no longer relies on satellite navigation — alternative navigation methods are used.  Only robust communication links allow UAVs to maintain operation through friendly EW environments.

Ukrainian UAVs Are Setting Global Standards

Since the start of the full-scale war, Ukrainian engineers have effectively set new standards in UAV design. Many European and American UAV platforms initially proved ineffective in EW-contested environments. Today, global technologies are evolving to meet these standards, while Ukrainian systems are designed from the outset for modern electronic warfare conditions.

UAV Design Evolution Under EW Pressure

Before the full-scale invasion:

▣ Widespread use of European and American UAVs with a single communication channel.
▣ Adversary EW threats are present and continuously evolving
▣ It is necessary to enhance communications and system resilience against EW to prevent the effects of adversary EW.
▣ Focus on the quantity of UAVs, as intelligence relies on UAVs with limited functionality.

In 2025-2026

▣ Two communication links are the minimum requirement.
▣ Friendly EW impacts missions more than adversary EW. EW resilience is critical for safe takeoff and landing.
▣ Emergence of interceptor drones requires changes in UAV design, range, speed, and altitude. It is not enough to simply develop an EW-resistant UAV.
▣ Quality outweighs quantity: a single high-capability UAV can perform complex missions and safely return.

Vulnerable UAVs cannot withstand competition and modern conditions

Not all UAVs have adapted to the realities of electronic warfare. Technological threats evolve rapidly, and legacy solutions are no longer reliable benchmarks. The ANT team continuously improves unmanned aerial systems and delivers updated UAVs for the Armed Forces of Ukraine. EW resilience is not optional — it is a critical factor in mission success.
