RTX stock wins DARPA phase-one contract for optical processing

Raytheon, RTX's defense business, received a phase-one contract from the U.S. Defense Advanced Research Projects Agency on November 3 to develop an all-optical processing system under the PICASSO program. RTX announced the award in an RTX release.

The Photonic Integrated Circuit Architectures for Scalable System Objectives program centers on photonic circuit technology that uses light rather than electricity to process signals. Raytheon's Advanced Technology team will design and demonstrate the system, with the stated aim of helping operators detect threats sooner, respond faster and maintain situational awareness in contested environments.

Light-Based Processing Targets Speed

Raytheon said current photonic circuits convert optical signals into electrical signals for further refinement and processing. Removing that conversion step could help preserve signal strength and integrity as circuits become smaller and more complex. The announcement did not disclose a contract value or a production timetable, and the phase-one award remains a development effort rather than a confirmed production order.

Colin Whelan, president of Advanced Technology at Raytheon, said the program reflects a shift toward processing critical information entirely in the optical domain. The company will draw on photonics process development, radio-frequency design and fielded military systems. Synopsys will support the project with design and simulation tools.

RTX Stock Holds Above Xetra Close

RTX stock traded at 176.30 euros on Lang & Schwarz at 14:05 CET on Thursday, November 5, 2026, 0.86 percent above the Xetra close of Wednesday, November 4. Investors can follow the real-time quote of RTX Corporation stock.

The DARPA project adds a research milestone to RTX's defense portfolio, but its near-term financial effect cannot be inferred from the announcement. For investors, the relevant test is whether the technology progresses from demonstration work into funded military applications and larger programs.
