The U.S. Navy awarded more than $170 million in Trident II D5 support contracts on October 1, 2026. L3Harris Interstate Electronics captured the largest award at $46.85 million for instrumentation engineering and logistics supporting the Columbia-class ballistic missile submarine program's advance toward service entry.
What's happening
- L3Harris Interstate Electronics received $46.85 million to engineer, maintain and operate Navy-owned instrumentation for Trident II flight tests and related support operations.
- Total contract value across all Trident II awards exceeded $170 million, spanning flight-test support, missile operations, rocket motor storage and logistics.
- Options attached to the L3Harris award could increase its value to $207.1 million over the full performance period.
Why it matters
- Instrumentation and flight-test infrastructure are critical to validating Trident II D5 reliability before Columbia-class boats enter service, directly affecting strategic deterrent capability.
- Sustained logistics and maintenance support contracts ensure continuous operational readiness of test infrastructure and reduce schedule risk for the Navy's largest submarine modernization program.
- L3Harris's role securing end-to-end instrumentation support strengthens its position as a prime contractor for strategic missile systems supporting U.S. nuclear force modernization.
Financial impact
- L3Harris will recognize revenue from the $46.85 million L3Harris contract as engineering and logistics services are delivered; timing not disclosed.
- Contract options worth up to $160.25 million additional value ($207.1 million total minus $46.85 million base) remain unexercised and contingent on Navy requirements.
The fine print
- The $46.85 million figure represents the base contract award; options must be exercised separately by the Navy to reach the $207.1 million ceiling.
- Work involves Navy-owned instrumentation, meaning L3Harris operates and maintains government equipment rather than supplying new hardware.
