NAVAIR press release
A diverse team of 105 personnel from Air Test and Evaluation Squadron Two One (HX-21), H-53 Heavy Lift Helicopters Program Office (PMA-261), Marine Heavy Helicopter Squadron 461 (HMH-461), Marine Operational Test and Evaluation Squadron One (VMX-1), and Sikorsky pilots, engineers, technicians and maintainers successfully accomplished this second set of sea trials for the CH-53K. Sea trial testing took place aboard the USS Arlington, a San Antonio-class amphibious transport dock (LPD24), operated by the U.S. Navy.
“The latest sea trials were another great success for the CH-53K program. Data analysis has shown a greater CH-53K LPD launch and recovery envelope than that of the CH-53E.”
Col. Kate Fleeger, PMA-261 Program Manager
Sea trials are a series of tests to evaluate the performance of the aircraft at sea. Tests performed during the event included: launch and recovery; rotor start and shutdown; blade fold; and shipboard compatibility testing – all in increasing wind speed and varying wind directions relative to the aircraft.
According to Sarah Naiva, Assistant Program Manager for Test and Evaluation for the CH-53K, there are many variables potentially impacting a high-profile, high-risk event such as sea trials.
“We made the stars align for us with months of exhaustive planning and tireless collaboratio. The joint team overcame numerous challenges, such as tumultuous seas, and their hard work and dedication will provide the fleet with greater flexibility to launch and recover the CH-53K in more severe weather conditions and mission scenarios where an LPD has limited steering.”

Ship compatibility testing includes towing the aircraft around the deck and in the hangar, performing maintenance while aboard the ship, ensuring the aircraft fits in all the locations it needs to around the ship deck and hangar and evaluating chain/tie-down procedures.
“Ultimately, the results of these tests will enable the CH-53K to provide critical ship-to-shore heavy lift capability for future Marine Expeditionary Unit deployments,” said Naiva.
The Marine Corps continues to execute its transition from the CH-53E to the CH-53K and is on schedule to declare Full Operational Capability in FY2029.
