The Joint Direct Attack Munition (JDAM) is a joint U.S. Air Force and Department of Navy program.
So it is weird the article only mentions it being used on Air Force jets. Either the original press release said that or perhaps the author didn’t do much research.
My guess is the USAF is the lead agency for the test because they have the assets in place at Eglin AFB to conduct the test. Fully instrumented F-15Es, Live Fire Water ranges, Instrumentation in place to collect the data.
I believe the impact angle of the JDAM as it enters the water is critical.
If full scale development gets approved, then any aircraft that can carry a 2000 pound JDAM will eventually get certified to carry the Quicksink version.
Perhaps a rocketed version could be launched from a B-2 or B-21 from 100NM.
Who knows what the final Quicksink will look like.
