Kaman has secured a contract modification to supply additional joint programmable fuses (JPF) to the US Air Force (USAF).

The contract is valued at $58m. It is the first order under Option 12 of the company’s joint programmable fuse (JPF) contract with the air force, and requires its aerospace division to deliver unspecified number of fuses.

Kaman Aerospace Group president Greg Steiner said: "The JPF is the most functional and reliable bomb fuse in the US Military’s arsenal.

"This award for additional fuses signifies the critical capability and demand for the JPF that only Kaman can satisfy.

"The JPF is the most functional and reliable bomb fuse in the US Military’s arsenal."

"We are pleased to increase our backlog on this programme to $131m, solidifying the future of our largest single programme through 2016."

The JPF is manufactured at Kaman’s facilities in Orlando, Florida and Middletown, Connecticut. It is an electro-mechanical bomb safing and arming device, and is designed to allow the settings of a weapon to be programmed on wing in flight.

The bomb is claimed to be the USAF’s current bomb fuse of choice, and is used with an array of weapons, such as general purpose bombs and guided bombs that use joint-direct attack munitions, and paveway kits on a range of US and international aircraft.

Some of the aircraft using the fuse include the US’ F-15 Silent Eagle, F-16 Fighting Falcon, F-22 Raptor, A-10 Thunderbolt, B-1 Lancer, B-2 Spirit, B-52 Stratofortress, the MQ-9 Reaper unmanned aerial vehicle, as well as the international Mirage 3 and JAS 39 Gripen fighters.

Since 2002, Kaman has been providing the JPF to the USAF and 26 other countries worldwide.

Delivery of the fuses under the latest contract is expected to take place in 2016 and 2017.
