F-35Bs with special instruments are testing whether the advanced jet can operate on the Italian navy flagship

• Two US F-35Bs have landed on the Italian Navy aircraft carrier Cavour.
• In the coming weeks, the pilots and test team will collect data to certify that the ship can conduct carrier operations with Italy's own F-35s.

Two specially instrumented US F-35Bs from Air Test and Evaluation Squadron 23 (VX-23) at Naval Air Station Patuxent River (NAS Pax River), Maryland, landed aboard Italian aircraft carrier ITS Cavour, off the US East Coast, on March 1, 2021.

The flagship of the Marina Militare (Italian Navy) had left Naval Station Norfolk (Virginia) on February 28, in preparation of the four-week sea trials.

During the sea trials, the F-35 Patuxent River Integrated Test Force (ITF) will verify the compatibility between the 5th-generation fighter aircraft and the ITS Cavour. The trials also represent an important step towards declaring the Initial Operation Capability (IOC) of the F-35B in the Italian Navy, expected by 2024.

The landing of the F-35Bs aboard Cavour was a significant milestone for the Italian naval service, as it prepares to operate the 5th-gen. stealth jet from an aircraft carrier.

"It is a remarkable achievement for all of us, today, to see the fifth-generation fighter aircraft on our flight deck," said ITS Cavour Commanding Officer Italian Navy Capt. Giancarlo Ciappina in a US DoD release. "This represents, indeed, an outstanding success but, at the same time, a new challenge for the future of Italian Naval Aviation."

"Each and every officer and the whole crew are very proud to work closely with the F-35 Joint Program Office test team during these sea trials, and we are very well prepared to do the hard work to equip ITS Cavour and the Italian Navy with the Joint Strike Fighter's fifth-generation air combat capability," Ciappina said.

The pilots and aircraft join a test team of approximately 180 personnel from the NAS Pax River-based F-35 Integrated Test Force (ITF) embarked for up to four weeks of sea trials.

"Our team has trained extensively to prepare for this day, and I was honored to land one of the first two jets aboard Cavour," said F-35B test pilot US Marine Maj. Brad Leeman, the ITF test team project officer. Maj. Leeman and two other pilots attached to the Naval Air Warfare Center Aircraft Division (NAWCAD) Air Test and Evaluation Squadron Two Three (VX-23) at NAS Pax River, will fly the ITF jets during the flight test.

"The ITF plays a key role in the ship achieving carrier qualification in the near future," Leeman said. "All of our hard work planning and training will ensure a successful sea trial and ultimately lead to Italy achieving the milestone of initial operating capability."

In the next weeks, the pilots and test team will collect data that will ultimately lead achievement of the "Ready for Operations" status, that certifies the ship's and her crew's ability to safely conduct carrier operations with Italy's own F-35s.

"We are excited to be underway with the crew of Cavour and honored to contribute to the aircraft carrier achieving the Italian Navy's strategic goal of it being 'Ready for Operations,'" said Andrew Maack, F-35 Pax River ITF chief test engineer and site director.

Maack is embarked with the team, whose members have the engineering and test pilot expertise and experience to conduct F-35B envelope expansion flight test. "We look forward to a phenomenally successful shipboard detachment," he said.

As already reported, the sea trials will take place in an unspecified area of the Western Atlantic involving other assets, including ships and aircraft from the US 2nd Fleet to improve interoperability and strengthen the relationship between the two NATO Allies.
