Edwards’ testers complete Joint Strike Missile test program

The next step is for the Norwegians to integrate the Joint Strike Missile on to the F-35 Joint Strike Fighter and then on to further weapons and integration testing

A team of U.S. Air Force (USAF) engineers, test pilots and Norwegian government and industry personnel recently completed a large phase of testing for the Joint Strike Missile (JSM).

The JSM is Norway’s advanced anti-surface warfare missile designed to be carried in the new F-35A’s internal weapons bay. The missile can be employed against sea- and land-based targets. Norway is a partner nation in the development of the fifth-generation Joint Strike Fighter.

As reported by Kenji Thuloweit, 412th Test Wing Public Affairs, in the article Edwards test squadron completes Joint Strike Missile test program, before proceeding with integration testing on the F-35A, the JSM was tested at Edwards AFB on F-16 Fighting Falcons from the 416th Flight Test Squadron (FLTS).

“As a mature platform with certified interface standards, the F-16 makes a perfect carriage platform for weapon development while the eventual host aircraft is still under test,” said Collin Drake, 416th FLTS JSM project engineer. “It made it a lot more efficient and effective to use F-16s to be able to test mid-cycle a new type of weapon.”

Drake said the weapons development program at Edwards began in 2015. The JSM missile system was matured and proven with ground testing, captive carriage testing (flight test missions to ensure the weapon would perform its designed functions prior to being released from the aircraft), and live-drop testing to verify the JSM’s ability to be safely released from the aircraft and perform its autonomous functions.

Testing included multiple variants of the JSM that increased in complexity and capability throughout the course of the program with the first JSM being a glide-only weapon with an active autopilot, but without a live engine, according to Drake. The next several tests used a version of the JSM that still did not have a warhead, but had a live engine and navigation avionics. The different variants proved the JSM could sustain extended periods of flight under its own power and successfully navigate over different terrain.

All variants of the JSM were inert until the final flight test events where it actually hit a target with full mission systems software and guidance. Throughout the test program, numerous software and hardware changes and updates were made. All live releases of the weapon were conducted at the Utah Test and Training Range.

“The multi-national test team, including the 416th, was able to work with the weapon developer over the course of the program to improve the JSM in an incremental fashion, which has resulted in a reliable and high-performance missile system,” Drake said. “It was an enormous milestone to release the final, all-up-round weapon.”

Edwards AFB’s airspace, personnel, assets and the American-Norway alliance make it the ideal situation to test the JSM.

“The weapons ranges needed simply don’t exist in Norway. So they were able to come here and utilize the Edwards airspace and ground test facilities for the captive carriage flight and ground testing. The 416th FLTS has a long and storied history of testing systems with our foreign partners, especially with Norway. Norway has been a partner in F-16 development since its inception, so it was a natural fit to work with the Norwegian Ministry of Defense to make this technology development program a reality. The 416th is equipped to provide flight test expertise and is adaptable to accommodate the testing of first-of-its-kind hardware and software, such as that of the Joint Strike Missile,” said Drake.

The next step is for the Norwegians to integrate the JSM on to the F-35 Joint Strike Fighter and then on to further weapons and integration testing.
