# Navy Awards $170 Million Trident II Support Contracts

The U.S. Navy awarded more than $170 million in Trident II D5 support contracts on October 1, with work covering flight-test instrumentation and other missile operations and sustainment needs as the Columbia-class submarine program advances. The largest identified award, a $46.85 million contract to L3Harris Technologies’ Interstate Electronics Corp., covers engineering and related support for Navy-owned instrumentation; options could increase that award’s value to $207.1 million.

- The awards signal continuing demand for specialized engineering, logistics, instrumentation, installation, and maintenance capabilities supporting the Trident II program.
- Contractors with relevant test instrumentation and missile sustainment experience may find opportunities in subcontracting and related support work; the signal does not identify additional solicitation details or deadlines.
- Companies evaluating the identified award should distinguish its $46.85 million base value from the potential $207.1 million value if options are exercised.
