The U.S. Navy has awarded a pair of sole-source contracts to a BAE Systems subsidiary and Boeing (NYSE: BA) for support work on the military branch’s Trident II D5 fleet ballistic missile system.
BAEÂ Technology Solutions and Services will provide systems engineering and integration services for the Trident FBM under a contract that contains $56.6 million in base value and could reach $368.7 million in total value if all options are exercised, the Defense Department said Monday.
Work also covers SSGN attack weapon system and nuclear weapon surety support.
Boeing received a separate contract with an initial value of $32.8 million and a potential ceiling of $88.9 million to provide materials, labor and services for the Trident’s inertial navigation equipment, according to DoD.
DoD added the Navy will initially obligate a total of $89.3 million to both contractors upon the availability of the branch’s operations and maintenance funds and research development test and evaluation funds in fiscal year 2017 as well as funds from the government of U.K.
BAE’s contract has one base year and options that could extend the performance period through Sept. 30, 2021.
Boeing’s contract has three base years and options that could extend work through Sept. 30, 2020.
Lockheed Martin (NYSE: LMT) is the prime contractor for the Trident II D5,  a successor to the Navy’s Polaris, Poseidon and Trident I C4 missile systems.
Trident II D5 missiles have been fielded on U.S. Ohio-class submarines and U.K. Vanguard-class submarines.
