The F-35B moved another step forward to shipboard testing on board USS Wasp (LHD-1) this year, as F-35 integrated test force personnel used weights to simulate shipboard padeyes during an evaluation of chain down procedures on F-35B test aircraft BF-1.

The team observed no points of interference and identified ways to optimize aircraft jacking techniques.
 
Padeyes are used on ships to secure equipment to the deck during various sea states.

The F-35B and F-35C Lightning II Joint Strike Fighter variants are undergoing test and evaluation at Naval Air Station Patuxent River, Maryland, prior to eventual delivery to the fleet.
