Boeing said the JDAM Extended Range kit, with modular add-on wings that unfold in flight, will enable a glide range of 40 miles for a 500-pound bomb -- triple the current range with a JDAM kit.
The JDAM-ER is being developed in partnership with the Australian government under a 2011 contract and will be produced in Australia.
"Boeing and our Australian partners have worked closely together to employ affordable technology and the leanest manufacturing processes to cost-effectively enhance JDAM's capabilities," said Debbie Rub, Boeing vice president and general manager for Missiles and Unmanned Airborne Systems.
"The JDAM-ER effectively meets the needs of the Commonwealth (of Australia) by providing a greater stand-off capability and making it safer for pilots to prosecute their missions on today's ever-changing battlefields."
Boeing said the JDAM-ER, first demonstrated in 2008, can also be coupled with other modular enhancements, including laser sensors.
Initial deliveries of the kits are expected to begin in early 2015.
JDAM converts free-fall bombs into a more precisely guided weapon.
