USS Gerald R. Ford endures final blast to complete shock trials

The US Navy’s lead Ford-class carrier, USS Gerald R. Ford (CVN 78), successfully conducted a third and final explosive event off the coast of Florida, 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 first two shots of the FSST sequence occurred on June 18 and July 16 this year.

“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,” said Capt. Brian Metcalf, manager for the navy’s future aircraft carrier program office, PMS 378. “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.”

Metcalf said that the goal of the tests is to ensure that Ford’s integrated combat systems perform as designed and added “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.”

CVN 78 is returning to the Tidewater area for a six month planned incremental availability (PIA) overhaul. 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.

Rear Adm. James P. Downey, program executive officer for aircraft carriers, rode the ship during the first and third shock evolutions, and observed the trials first-hand. “FSST has proven a critical investment in the Ford-class development,” said Downey. “The ship and crew performed exceptionally in these very strenuous conditions and continued their operations throughout the shock events, demonstrating the ship’s ‘fight-through’ capability.”

“We’re designing and building these aircraft carriers to sail in some of the world’s most contested security environments. So when you think about the threats to warships posed by non-contact blasts and the number of sea mines in the inventories of navies around the world, the gravity and consequence of these shock trials really come into focus. The Navy’s ongoing investment in the design, including this modeling, will help ensure the resiliency of Ford’s integrated, mission critical systems in underway threat environments.”

Downey added that the trial’s ultimate success hinged on the extraordinary performance of ship’s force, in coordination with crews on several surface and aviation platforms that support FSST.

“The countdown to the actual shot is choreographed down to the smallest detail, and the coordination between the ship and the other surface and aviation platforms, as well as the on-scene environmental scientists has been impressive.”

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.

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.

Ford’s Commanding Officer, Capt. Paul Lanzilotta, was the tactical commander that ordered the go/no-go decision, based on the interplay of several crucial variables, such as ship and crew readiness, weather, and sea state, as well as pre-set environmental mitigation measures, designed to protect any marine life spotted within the test area.

“Safety was always the driving consideration throughout the shock trials,” recalled Lanzilotta. “So, once we were ready and in position, pausing the countdown to the shot could really test our focus and persistence.”

“In spite of months of detailed preparation, you can’t always count on the weather,” he said. “But the crew hung in there, and showed the great tenacity and professionalism reflective of their pride in our warship.”

The US 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.
