The fuzes allow a bomb's settings to be programmed while on an aircraft in flight.
The JPF is used with general purpose bombs, and guided bombs that use JDAM or Paveway kits, on U.S. aircraft such as F-15, F-16, F-22, A-10, B-1, B-2, B-52 and the MQ-9 unmanned aerial vehicle.
"This order further solidifies the outlook for our largest single program with a backlog of $117 million that extends into 2016," said Kaman Aerospace Group President Greg Steiner. "The order demonstrates the USAF's continued fuzing requirements and commitment to the program."
The order is worth $8.5 million and is the eleventh option exercise of an earlier contract. With the new order, that contract now has achieved a value of about $50.4 million.
Kaman said units to be produced under the extension will be delivered next year and in 2016.
In addition to the United States, 26 other countries utilize Kaman's fuzes.
