This month, the USS Gerald R. Ford, the US Navy’s newest aircraft carrier, successfully completed its shock trials. The third and final 40,000-pound explosive detonated near the Ford’s hull and caused no major injuries, flooding, or fires.

“We had zero catastrophic failures on the ship, zero situations where we had flooding or anything, and zero fires. All that is pretty significant,” Capt. Paul Lanzilotta, the Ford’s commanding officer, told reporters.

The shock trials are the latest milestone for a carrier that has struggled through years of delays and cost overruns — setbacks caused at least in part by the many brand-new systems the Navy chose to put on its newest class of carrier, the service’s top officer said in July.

In an interview at a Navy League event, Chief of Naval Operations Adm. Michael Gilday said the Navy had been too ambitious with the Ford’s new technologies.
