Optics11 banks €100M to push fiber-optic sensors into global navies
A Dutch defense technology firm, Optics11, has raised about €100 million to bring its fiber-optic underwater surveillance systems to more navies. Its sensors can spot an oil tanker 100 kilometers away—far beyond the reach of conventional sonar. With contracts from five to ten naval customers already signed, the company is racing to scale production before its next funding round in 2027.

30 SEC SUMMARY
- Optics11, a Dutch defense tech firm, raised €100 million to expand its fiber-optic underwater surveillance systems.
- Its sensors detect oil tankers 100 kilometers away—far beyond conventional sonar range.
- The company already serves 5–10 navies and has 35 paid evaluations scheduled for 2026.
- Optics11 expects to reach positive cash flow by 2028 and aims for a $1B+ valuation in its 2027 funding round.

€100 million injection to scale underwater sensors
Optics11, a Dutch defense technology company, just closed about €100 million in funding over the past 15 months. The European Investment Bank contributed €25 million in venture debt to the round.
The money will scale its fiber-optic underwater surveillance systems, which use light pulsing through optical fibers to pick up acoustic vibrations across dozens of kilometers.
How the sensors outrange sonar—and what it costs users
A single Optics11 sensor can detect an oil tanker 100 kilometers away—roughly twice the range of legacy sonar.
The company sells two configurations: OptiBarrier, a fixed seabed array, and OptiArray, a towed line that ships can pull behind them.
Both systems flood operators with far more acoustic data than conventional sonar. Off-the-shelf software can’t handle the load, so Optics11 built its own processing suite in-house.
AI cut the software team from 60–80 developers to about 10 while keeping pace with the data deluge.
Global navies adopt the tech as contracts pile up
Between five and ten navies have already bought Optics11’s systems. Another 35 paid evaluations are booked for 2026.
One flagship contract is with the Royal Netherlands Navy: Optics11 is tailoring a towed OptiArray for the future Orka-class submarines, which French shipbuilder Naval Group will deliver.
Other defense contractors—Saab, Rheinmetall, Thales, Fincantieri, Exail—and UK maritime surveillance firm Ocean Infinity have all inked partnerships with Optics11.
2027 funding round targets $1B+ valuation
CEO Paul Heiden told TechRadar the company is on track for positive cash flow by 2028.
Next summer, Optics11 will launch another funding round, eyeing a valuation above $1 billion.
Expansion teams are already on the ground in Southeast Asia and the Middle East, where territorial disputes are driving demand for long-range underwater sensing.
What this means
Lazyfounder analysis — our interpretation, not reported fact.
Optics11’s fiber-optic sensors give navies a longer detection range than traditional sonar, but the data deluge forces buyers to adopt Optics11’s proprietary software—or risk missing threats.
Key takeaways
- Navies can now spot oil tankers at 100 km, but only if they use Optics11’s software to handle the data.
- Optics11’s customer list grew from zero to 5–10 navies in 15 months, with 35 more evaluations booked for 2026.
- The €100 million war chest funds expansion in Southeast Asia and the Middle East, where maritime tensions are rising.
- A $1B+ valuation in 2027 is plausible if the Royal Netherlands Navy’s Orka-class integration succeeds.
