Delivery of the fuze order, known as Option 10, will begin next year.
Kaman said the award to its aerospace segment also features two follow-on options, which would extend deliveries through mid-2017.
"This contract award from the Air Force signifies the critical capability that the JPF provides to our men and woman in uniform," said Neal J. Keating, Kaman Corp.'s chairman, president and chief executive officer.
"The JPF is the most functional and reliable bomb fuze in the U.S. military's arsenal. We are pleased to solidify the future of our largest single program."
Kaman has been the sole provider of the JPF to the USAF since 2002.
The fuze allows the settings of a weapon to be programmed in flight.
