The Joint Operational Fuel System contract has an initial period of performance of two years, KBR reported.
"The award of this contract is key to the strategic development of our U.K.-based support to the Ministry of Defense," said Andrew Pringle, president of KBR's International Government, Defense and Support Services.
"The MOD remains a key client of IGDSS and we look forward to ensuring that the MOD continues to receive outstanding support."
KBR, which has headquarters in Houston, said that under the contract it would provide fuel-handling equipment and services but didn't provide specifics on the equipment it will supply to the Ministry of Defense or the services it will render.
KBR is a global engineering, construction and services company.
