From USNI News:

The landing of the Super Hornet marks the start of manned aircraft tests for the system that was also installed in parallel on Gerald R. Ford (CVN-76) — currently finishing construction.

The facility in New Jersey had arrested simulated dead loads and jet cars ahead of the first manned arrested landing with the Super Hornet from Naval Strike Aircraft Test Squadron 23 (VX-23) on March 31, according to a General Atomics statement.
“More than 1,200 successful dead load arrestments have been completed at the Jet Car Test Site in Lakehurst, New Jersey,” stated Dean Key with General Atomics said in the statement.
“Now, with the arrestment of aircraft, we take an important step in verifying the dynamic controls and system performance as a whole.”
