Signals Intelligence Market Size, Share & Trends Analysis Report By Solutions (Airborne, Ground, Naval, Space, Cyber), By Type (ELINT, COMINT), By Mobility (Fixed, Portable), By Region, And Segment Forecasts, 2026 - 2033

Signals Intelligence Market Summary

The global signals intelligence market size was estimated at USD 18.51 billion in 2025 and is projected to reach USD 28.51 billion by 2033, growing at a CAGR of 5.5% from 2026 to 2033. The market growth is driven by rising geopolitical tensions, increasing defense surveillance spending, the rapid adoption of advanced electronic warfare and cyber intelligence capabilities, the growing use of AI and big data analytics for real-time signal processing, and the expanding demand for border security, counterterrorism, and maritime domain awareness solutions.

The global signals intelligence (SIGINT) industry is being driven by the rapid integration of artificial intelligence and machine learning, which enable real-time signal processing, automated classification, and faster threat detection.

The growing demand for software-defined and modular SIGINT systems enables militaries to rapidly upgrade and configure platforms for multi-mission applications, thereby enhancing operational flexibility. Multi-domain intelligence fusion across land, air, sea, space, and cyber domains is increasingly critical, providing comprehensive situational awareness for complex threat environments. Portable and network-centric SIGINT platforms, combined with space-based signal processing, are expanding tactical reach and enabling faster data dissemination to command centers. In addition, rising defense budgets and escalating geopolitical tensions continue to fuel investments in advanced SIGINT capabilities, ensuring militaries remain resilient against evolving electronic threats.

The increasing demand for end-to-end mission support is reshaping the ground segment of the space industry as governments and commercial operators expand their satellite fleets. This shift is accompanied by a growing preference for integrated ground infrastructures that combine control, communications, navigation, and data processing to enhance mission resilience and reduce operational silos. For instance, in June 2025, Indra Group launched enhanced ground-segment capabilities through its newly established Indra Space business unit. The company now offers comprehensive solutions covering satellite command and control, data downlinking, mission operations, control centers, earth stations, and integrated communication and navigation systems. This initiative reinforces Indra’s position as a full-value space solutions provider by reducing reliance on external partners and strengthening its competitiveness across defense, civil, and commercial space applications.

The signals intelligence industry is increasingly influenced by growing requests for real-time data processing and AI-enabled space-domain awareness in response to a more contested and congested operational environment. Stakeholders are showing heightened interest in developing integrated ground, space, and on-orbit signal processing capabilities that leverage AI to detect, classify, and track objects, enabling anticipatory decision-making and effective threat response.

For instance, in June 2024, Voyager Space announced a partnership with Palantir Technologies to integrate Palantir’s advanced AI tools across Voyager’s space and defense operations. The collaboration utilizes Palantir’s AI platform to enhance payload management systems for the International Space Station and the Starlab commercial space station, aiming the reduce data processing burdens and complexity in mission operations. This partnership establishes a new benchmark for AI-powered signal intelligence in space, allowing Voyager to deliver more advanced, responsive, and comprehensive capabilities to both defense and commercial customers.
