In 2023, Germany’s business enterprise R&D expenditure in aerospace manufacturing stood at approximately 2.10 billion USD (PPP). The projections from 2024 to 2028 suggest a gradual decrease: 2.07B in 2024, 2.04B in 2025, 2.0B in 2026, 1.97B in 2027, and 1.94B in 2028. The year-on-year reduction from 2023 through 2028 highlights a consistent downward trend, with an estimated compound annual growth rate (CAGR) indicating a steady annual decline.

Future trends to watch for:

Impact of emerging green technologies on R&D priorities and budgets in aerospace.
Potential for increased investment driven by advancements in space exploration technologies.
Influence of geopolitical factors on aerospace investment and innovation.
The rise of international collaborations in R&D efforts within the aerospace sector.
