X-Bow Systems Achieves First In-House Electronic Ignition Safety Device Test for Solid Rocket Motors
Event summary
- X-Bow Systems successfully fired a solid rocket motor (SRM) ignitor using its in-house designed Electronic Ignition Safety Device (eISD) on April 20, 2026.
- This marks the first time a solid propellant provider has independently developed and tested an electronic ISD, traditionally sourced from third-party specialists.
- The eISD is now baselined in multiple SRMs currently in development at X-Bow, including the Mk 72 booster and Mk 104 dual-thrust SRM for the U.S. Navy's Standard Missile 6 program.
- X-Bow completed the Preliminary Design Review (PDR) for both contracts, underscoring rapid progress in supporting the Navy's evolving needs.
The big picture
X-Bow Systems' achievement in developing and testing its own Electronic Ignition Safety Device (eISD) represents a significant shift in the defense and aerospace industry. Traditionally, ISDs have been managed by prime integrators and sourced externally, often resulting in costly delays and program risks. By bringing eISD development in-house, X-Bow is strengthening its vertical integration, reducing costs, and accelerating delivery timelines. This strategic move enables X-Bow to deliver critical capabilities to the warfighter faster, supporting urgent defense needs and strengthening national security. The company's rapid progress in completing the Preliminary Design Review (PDR) for the U.S. Navy's Standard Missile 6 program underscores its commitment to supporting the Navy's evolving needs.
