Looks like it might be some flavour of missile test, based on this post: https://forum.nasaspaceflight.com/index.php?topic=8184.msg2647802#msg2647802Ross.
Not sure where to put this. The LRHW Dark Eagle apparently flew from Cape Canaveral yesterday, December 12, 2024. Complex 46 hosted the launch.https://defensescoop.com/2024/12/13/army-navy-second-hypersonic-missile-test-2024-aur-lrhw-dark-eagle-cps/https://www.floridatoday.com/story/tech/science/space/2024/12/12/u-s-military-launches-dark-eagle-hypersonic-missile-from-cape-canaveral-space-force-station-florida/76943770007/ - Ed Kyle
Flight testing of the AUR continued with an attempted launch from the Army’s LRHW (Dark Eagle)prototype TEL in March 2023. This test, Joint Flight Campaign-2 (JFC-2), did not occur due tochallenges in pre-flight checks. The JFC-2 Retest (JFC-2R) was attempted in September 2023 butdid not occur as a result of pre-flight checks. The JFC-3 test is planned for FY24, also planned to belaunched from the Army LRHW TEL. JFC testing continues through FY29 using both Navy and Armylaunchers.
Successful LRHW Flight TestOn June 28, 2024 DOD announced, The U.S. Navy and U.S. Army recently completed an end-to-end flight test of a hypersonic missile from the Pacific Missile Range Facility, Kauai, HI. Reportedly, the two-stage missile was launched from a ground stand from Hawaii across the Pacific Ocean more than 2,000 miles to a test range in the Marshall Islands, with the missile flying its intended course and releasing the C-HGB, which flew to the target.
Third try is the charm. JFC-2 (joint flight campaign) is in the books. The Conventional Prompt Strike campaign phase 1 called for 5 flight tests. The Navy has completed JFC-1 and JFC-4 but the launcher hardware failures delayed the Army flight tests (JFC-2 and JFC-3. Hopefully the flight was nominal and the CPS/LRHW program can get back on track. Success of this test today was a huge milestone for Lockheed Martin, the prime contractor and supplier of the "Dark Eagle" launch hardware. "Under the gun" would be an understatement.
According to U.S. media reports, at about 11:30 local time on December 12, the U.S. Army's "Dark Eagle" long-range hypersonic missile (LRHW) conducted the first vehicle-missile test launch in Florida, and the flight code name was "Joint Flight Test 2R3" (JFC-2R3). Subsequently, the website of the US Department of Defense announced that the test launch of the "Dark Eagle" hypersonic missile was a success, and this is also the second successful test launch of the "Dark Eagle" missile this year.
