Best Aerospace, Maritime and Defense Tech Companies in Spain
The 176 best Aerospace, Maritime and Defense Tech companies in Spain in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: EOS-X SPACE.
Spain's Aerospace, Maritime and Defense Tech sector has 176 tracked companies and $457M in disclosed funding, and if you want to know who's leading that pack, this ranking cuts straight to it, ordered by equity raised and recent momentum.
Two names dominate the capital table. Eos-X Space and PLD Space have pulled in $140M and $139M respectively, together accounting for well over half the sector's total disclosed funding. That concentration tells you something real about where conviction is running. The global aerospace and defense market sits at roughly $1.07T and is forecast to grow at a 5.9% CAGR through 2027, driven by rising strategic investment and geopolitical realignment that's reshaping procurement priorities across Europe. Spain's active investor list, anchored by the EIC Fund, CDTI, and Europa, reflects exactly that institutional push. I'd also flag the digital signal: median install growth across 68 aerospace, maritime and defense apps is tracking at plus 15% year-on-year, as shown in 2019 research on connected defense systems, which suggests real end-user engagement growing alongside the hardware bets. Bound4blue at $23M rounds out the meaningful raises, while the remaining companies cluster well below $5M, meaning the funding story here is top-heavy and still consolidating.
