Redwire (RDW) Lands ESA Quantum-Secure Satellite Contract for QKDSat Program

Redwire Corporation (NYSE:RDW) is one of the best space stocks with high upside potential.

On April 2, 2026, Redwire said it had been awarded a contract to develop a quantum-secure satellite for the European Space Agency’s Quantum Key Distribution Satellite, or QKDSat, under ESA’s ARTES Partnership Projects program. The company said it will manufacture and deliver its European-built Hammerhead spacecraft, which will carry the quantum key distribution payload along with Redwire’s ADPMS-3 avionics suite.

Redwire said the project is part of a multi-country consortium led by Honeywell Aerospace’s UK team and is aimed at enabling satellite-based quantum key distribution to protect communications against data breaches.

Management framed the award as a step toward more resilient long-distance secure communications, noting that satellite quantum key distribution can overcome the distance limits of terrestrial fiber-based quantum networks. ESA also described the program as important for secure commercial and government communications across member states amid rising cyber threats.

Redwire Corporation (NYSE:RDW) is an integrated aerospace and defense company focused on advanced technologies spanning space infrastructure, autonomous systems, and multi-domain operations.
