Should governments prioritize increasing spending on space-based defense and intelligence capabilities?
Novaspace projects the launch of 2,306 defense intelligence, surveillance, and reconnaissance (ISR) satellites between 2026 and 2035. This marks a significant increase from the 485 such systems deployed during the previous decade.
Why it matters
Governments are rapidly scaling space-based assets to secure persistent, real-time intelligence for military operations. This trend follows heightened reliance on orbital data observed during recent conflicts, driving a surge in global defense spending.
The projected launch volume represents a substantial ramp-up from the current baseline of 18,000 active satellites. Experts anticipate that the total number of operational space systems could increase fivefold by 2036, reaching between 50,000 and 100,000 units.

The details
These defense ISR satellites — orbital platforms designed for intelligence, surveillance, and reconnaissance — will function as distributed constellations. Rather than relying on singular high-cost hardware, nations are diversifying their assets to ensure persistent coverage. This architectural shift enables real-time data collection, a necessity proven by military dependence on space-based intel during active combat zones.
Timeline
2022: Global government space defense spending totaled $53 billion.
March 2025: The United States experienced a brief halt in its space data sharing.
2025: Government spending on space defense reached $74 billion.
2026-2035: Projected timeframe for the launch of 2,306 defense ISR satellites.
2028: Government space defense budgets are forecast to reach $121 billion.
The Tech Race
This forecasted expansion represents a fundamental shift away from monolithic, high-cost military satellites toward resilient, distributed constellations. Nations are competing to secure persistent orbital presence, fundamentally altering the traditional intelligence-gathering race.
The transition to massive satellite constellations will likely change the speed and granularity of intelligence data available to military and civil decision-makers. As spending scales to $121 billion by 2028, the density of low-earth orbit will increase, creating new operational requirements for collision avoidance and tracking.
The takeaway
The move toward massive, distributed satellite networks is no longer a research goal but an active procurement strategy across 55 nations. Monitor upcoming annual defense budget reports to see if spending trajectories meet the forecast of $121 billion by 2028.
