Underwater blast intended to evaluate how well carrier survives severe vibration.

The United States Navy has conducted the first shock trial of the first-in-class carrier, USS Gerald R. Ford. It is the first time since 1987 that the navy has carried out shock trials on a carrier — the last carrier to be thus tested was the USS Theodore Roosevelt.
The navy says the dramatic trial allows it to evaluate the new carrier’s resilience to severe close-quarter vibration. According to the United States Geological Survey, the blast was large enough to register 3.9 on the Richter scale.
In a statement, the navy said: “Ford’s shock trials are being conducted off the East Coast of the United States, within a narrow schedule that complies with environmental mitigation requirements, respecting known migration patterns of marine life in the test area.
“The Navy also has employed extensive protocols throughout FSST [Full Ship Shock Trials] to ensure the safety of military and civilian personnel participating in the testing evolution.”
