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.
“Perhaps a rocketed version could be launched from a B-2 or B-21 from 100NM.”
Sounds like a perfect use for a cruise missile with long stand-off distance and precise terminal guidance to put the JDAM in the water close to the hull.
