The work will mostly be performed in Magna, Utah (33.5 percent), Sunnyvale, California (13.7 percent); Denver (10.6 percent); Cape Canaveral, Florida (6.9 percent); and other various locations and is expected to be finished by September 2024.

The Trident II D5 nuclear-armed missiles are deployed on Ohio-class ballistic missile submarines.

Obligated funding for this work is split among $499 million in fiscal year 2021 Navy weapons procurement, $93 million in United Kingdom funds, and $500,000 in incremental FY 2020 Navy research and development accounts with none set to expire at the end of this fiscal year.

The contract was awarded on a sole source basis.

Previously, the Navy awarded Lockheed Martin a $495 million modification for this contract last September.
