(Inputs to Questions)
Q1. Compressing the Sensor-to-Shooter Timeline
In today’s evolving warfare landscape, the true strength and deterrence now come from long-range strike weapons, unmanned systems, loitering munitions, airborne tankers, space-based ISR networks, and the collaboration between manned and unmanned systems. This shift in military strategy calls for a broader structural change. Delays in taking action are no longer just tactical setbacks; they become a significant strategic vulnerability.
The sensor-to-shooter timeline compression is not only a technological problem but also a fundamental issue in decision architecture. Compressing that timeline requires work in several areas.
First, satellites must carry onboard AI capable of detecting, classifying, and cueing targets. They should be able to transmit actionable intelligence over tactical data links. This eliminates the round-trip to a ground station for analysis.
Second, pre-authorised engagement envelopes, i.e. defined target criteria against which strike authority is delegated to the satellite before conflict begins. A satellite can trigger an execution sequence rather than a consultation.
Third, a direct machine-to-machine network between ISR assets and strike platforms, with AI cross-referencing satellite data with other sensors (UAVs, SIGINT, and ground radars) to automatically produce a confidence-rated target package.
The legal and ethical concerns surrounding a misattributed strike are understandable, highlighting the importance of having a careful approach in the kill chain. It’s essential to keep the human in the loop, ensuring the human authorises each kinetic attack. While smart machines can identify and designate targets, human oversight remains a crucial safeguard.
Q2. Fighting Through the Electronic Fog
Fighting through the Fog of war has existed since wars began. Electronic fog is a part of it. In the future, assessments of the threat environment should treat GPS jamming and ISR spoofing as baseline assumptions in conflict scenarios. The opening moves of any conflict involve cyber and electronic attacks before any kinetic exchange. Electronic attack is now a feature of even ostensibly non-combat environments (IAF aircraft flying into earthquake-hit Myanmar faced GPS spoofing).
The response must be across three levels. At the platform level, the need is for integrated systems with multiple guidance modes (inertial navigation, terrain-referenced navigation, NavIC integration, and optical terminal guidance). so that loss of GPS does not render the platform/weapon ineffective. Multi-constellation receivers (combining NavIC, GLONASS, and Galileo) would force an adversary to jam multiple frequencies simultaneously. In the future, quantum computing will enable precise navigation without reliance on GPS. At the same time, the implementation of quantum cryptography will secure communications.
At the space segment level, satellites should be capable of operating in a degraded communications environment. Resilience must be built into the architecture from the outset. They need anomaly-detection capability, frequency agility and hardened electronics. Optical communication between satellites is one way of reducing RF vulnerability.
At the operational level, the goal is not to eliminate the electronic fog but to remain functional inside it. Combat personnel must train regularly in GPS-denied and communications-degraded environments. Spectrum-agile systems, low-probability-of-intercept communications, and redundant networks are required to counter EW threats. Redundancy in sensors, communications, and commanders’ cognitive habits produces all-around resilience.
Q3. Distributed Constellations vs. Exquisite Satellites
The doctrine of “space deterrence” has become a key part of modern defence strategies. Protecting satellites through resilience and backups is now more important than ever. While a single valuable satellite can be a tempting target, having a group of smaller satellites spreads out the risk, making the overall system much sturdier. Each small satellite is less critical on its own, but together, they create a network that’s much harder to disrupt.
However, there are some trade-offs. Smaller satellites can carry smaller payloads. They have lower sensor resolution and have narrower per-node bandwidth. They may be suitable for tactical ISR functions, but insufficient for certain high-end ISR requirements. The practical answer is a tiered architecture. A mix of a small number of high-capability strategic satellites complemented by a larger constellation of capable, expendable ones.
Stratospheric airships present an exciting alternative! Operating comfortably at altitudes of 20–30 km, they blend the long-lasting qualities of satellites with the flexibility of terrestrial systems. Unlike geostationary satellites, airships can be moved, repaired, or upgraded with ease, allowing them to adapt to changing mission needs. The successful flight trial of DRDO’s stratospheric platform in May 2025 is a significant milestone. While these platforms won’t replace satellites, they offer a cost-effective addition to the overall surveillance setup.
India’s SBS-III programme, targeting 52 dedicated military satellites (equipped with SAR, electro-optical, and infrared payloads), is a step in the right direction. The involvement of private industry in a significant portion of those satellites signals an important shift toward faster production and greater cost efficiency.
Q4. Fusing Space Assets into a Common Operational Picture
The data fusion problem is a real challenge. Without integration, more sensors produce more confusion, rather than clarity. The challenge is to get the processed sensor data to the right person, in usable form, at the right time. It is more of an organisational and doctrinal issue than a technical one.
The information from space sensors must be fused into a single picture. The Common Operational Picture that a field commander can rely on must be continuously updated and remain current. It needs AI-driven correlation engines that perform real-time multi-sensor fusion, with confidence scoring for each data element, so a commander knows not just what the picture shows but how much to trust it. Building this requires common data standards across the IAF, the Army, the Navy, and the Defence Space Agency. This is a foundational necessity.
The most critical single step is to establish a jointly manned Space and Intelligence Fusion Center. The center should have real-time data access, direct connectivity and the authority to produce an integrated assessment. In the current model, information from different agencies passes through separate chains before being reconciled at a higher level. It introduces a delay that defeats the purpose of persistent surveillance. AI-enabled networked solutions for data collection, analysis, planning, dissemination, and monitoring must sit at the heart of this center.
Q5. Responsive Space and Tactical Satellite Launch
Space is becoming more militarised, with countries developing anti-satellite weapons, directed-energy systems, and cyber tools to disrupt vital assets such as GPS, reconnaissance, and communications satellites. Countries that can quickly rebuild their space infrastructure during challenges enjoy a lasting edge over those that can’t.
Tactical gaps can arise during hostilities due to satellite attrition or new threat activity not accounted for in pre-conflict planning. The ability to task a launch in response to these situations is necessary. The concept needs a shift in mindset of viewing the space as a static strategic asset to a fluid manoeuvre domain. In the longer term, the vision of a field commander requesting coverage over a sector and receiving a dedicated satellite within 24 to 72 hours is both feasible and strategically significant.
Current launch timelines are measured in weeks or months, not hours. Closing that gap requires investment in small launch vehicles with rapid turnaround capability. India’s SSLV technology transfer to industry is a step in the right direction. A stock of ready-to-launch, pre-integrated satellites with modular payloads needs to be built up. Launch infrastructure capable of supporting surge operations, including mobile or dispersed pad options, would also be required.
The more immediately achievable priority is responsive tasking of satellites already in orbit. The existing assets should be dynamically reprogrammable to cover a priority area at short notice. That is primarily a software and ground architecture problem and should be the near-term focus while launch responsiveness matures.
