As for the stuff that isn't showing up on FlightAware, it's quite possible it's flight testing the MQ-9A reaper.
South NJ is among sites selected about 10 years ago.
It's the one of the only places that has military and commercial airspace side to side.

Anduril has been testing "Lattice" lately, too. I posted about this last week.
Anduril and Palantir have been integrating Maven Smart System

And this requires testing. VMUT-2 Performed it's First MQ-9A Reaper Flight at MCAS Cherry Point, and the Marines on the east coast in general have a new MQ-9a Reaper testing unit going up, they're called the "night owls". That being said, they're replacing all the RQ-21 Blackjacks with MQ-9A Reapers according to recent news. I heard this wasn't happening until spring 2025, but they could be flight testing the units prior to training the marines on them.

They like to just the "pepper" emoji when they're posting about it.
