Leonardo launches Guardian Vantage, a new passive land EW and SIGINT capability to detect, identify and locate battlefield emitters

20 May 2026

Leonardo has unveiled Guardian Vantage, a new land-based Electronic Warfare (EW) and Signals Intelligence (SIGINT) capability which detects, recognises, identifies and locates enemy emissions on the battlefield. The system is designed for use on land vehicles, ships, or for mounting onto shelters.

Modern operations are increasingly shaped by how effectively forces can sense and understand the electromagnetic environment. Guardian Vantage provides real time battlefield intelligence on emitting enemy systems such as radars, uncrewed aerial systems (UAS) and communications. This information can then be exploited by friendly forces for surveillance and target acquisition, to ultimately understand who the enemy is, where they are, and what they are doing.

Enemy emissions are fused into an integrated command and control (C2) system. Guardian Vantage generates an electronic order of battle (ORBAT), mapping detected systems and prioritising the most potent threats to give commanders a better understanding of likely enemy movements and potential danger to friendly forces.

Crucially, Guardian Vantage is a passive system and operates without generating emissions itself. This reduces the risk of detection for friendly forces and provides maximum freedom of action. The system works by analysing the electromagnetic spectrum (EMS), looking for anomalies and unusual patterns before comparing these signals against a threat library. Guardian Vantage is also capable of transcribing radio traffic in real time and can use large language models to translate foreign languages into the operator’s native tongue.

The unveiling of Guardian Vantage took place at the Association of Old Crows Europe (AOC Europe) event in Finland, where Leonardo Campaign Manager, Mike Brown, said: “Guardian Vantage turns the electromagnetic spectrum into a decisive operational advantage – enabling commanders to see what the adversary is doing and where they are operating, ultimately providing an indication of their intent. This provides critical decision advantage and enables forces to outmanoeuvre their adversaries.

“Built on an open architecture and designed with freedom of modification in mind, Guardian Vantage offers customers a future-proof path to sovereign electronic warfare and signals intelligence capability – with rapid upgrade potential as threats naturally evolve.”

Platform agnostic, Guardian Vantage can be integrated onto a wide variety of vehicles and maritime platforms, dependent on customer needs. The system is rapidly exportable, with no ITAR restrictions, and uses high-performance components and software from specialist small to medium enterprises (SMEs) CommsAudit, Esroe and Mercury – all manufactured in the UK.
