US Navy USS Gerald R. Ford (CVN-78) Conducts Final Full Ship Shock Trials (FSST)


The U.S. Navy USS Gerald R. Ford (CVN 78) successfully conducted a third explosive event off the coast of Jacksonville, FL, on 8 August, marking the completion of the ship’s Full Ship Shock Trials (FSST). Shock Trials validate a ship’s shock hardness and ability to sustain operations in a simulated combat environment using live ordnance. During the four-month testing evolution, the first-in-class aircraft carrier withstood the impact of three 40,000-pound underwater blasts, released at distances progressively closer to the ship.

“The Navy designed the Ford-class carrier using advanced computer modeling methods, testing, and analysis to ensure the ships are hardened to withstand harsh battle conditions. These shock trials have tested the resiliency of Ford and her crew and provided extensive data used in the process of validating the shock hardness of the ship. The tests demonstrated—and proved to the crew, fairly dramatically—that the ship will be able to withstand formidable shocks and continue to operate under extreme conditions.,” said Capt. Brian Metcalf, manager for the U.S. Navy’s future aircraft carrier program office, PMS 378.

CVN 78 is returning to the Tidewater area for a six month Planned Incremental Availability (PIA). As the PIA begins, teams will conduct additional detailed inspections, assess any damage sustained during the shots, and continue modernization and maintenance work in advance of workups for the ship’s deployment in 2022. FSSTs are complex evolutions, conducted during a precise operating schedule in compliance with exacting environmental mitigation requirements, respecting known migration patterns of marine life and protected species. Ford’s shock trials required exacting coordination across multiple Navy/Naval Sea Systems Command (NAVSEA) organizations and experienced FSST teams.

The FSST team notified mariners to avoid the test area, and implemented extensive protocols to ensure the safety of military and civilian personnel participating in the operation. A team of more than a dozen scientists, biologists, and observers were assigned to Ford, nearby support vessels, and observation aircraft. Observers used high-powered lenses to detect marine life at great distances, through ocean waves and white caps. During the sequence of events leading up to each shot, crews operated in a heightened state of watchful readiness in anticipation of the ultimate go/no-go decision, which had to be made between 4:00 and 8:00 a.m. on the day of the scheduled blast.

The U.S. Navy has conducted FSSTs over several decades, most recently for the Littoral Combat Ships USS Jackson (LCS 6) and USS Milwaukee (LCS 5) in 2016; as well as on the San Antonio-class amphibious transport dock USS Mesa Verde (LPD 19) in 2008, the amphibious assault ship USS Wasp (LHD 1) in 1990, and the guided missile cruiser USS Mobile Bay (CG 53) in 1987. The last aircraft carrier to execute FSST was USS Theodore Roosevelt (CVN 71) in 1987. The Navy conducted the Gerald R. Ford shock trial testing in accordance with Office of the Chief of Naval Operations Instruction 9072.2, and as mandated by the National Defense Authorization Act of 2016. The first two shots of the FSST sequence occurred on June 18 and July 16.

USS Gerald R. Ford is the newest and most advanced aircraft carrier in the U.S. Navy. The ship closed out a successful 18-month Post Delivery Test & Trials period in April, during which the crew completed all required testing, accomplished planned improvements and maintenance ahead of schedule, and learned valuable lessons to increase the reliability of Ford-Class systems. At the same time, the ship also served as the sole East Coast platform for conducting carrier qualifications. The Gerald R. Ford-class represents the first major design investment in aircraft carriers since the 1960s. CVN 78 is engineered to support new technologies and a modern air wing essential to deterring and defeating near-peer adversaries in a complex maritime environment.
