Aircraft carrier HMS Queen Elizabeth is expected to sail to the United States any day now for a series of trials with F-35 jets.

The four-month WESTLANT 18 deployment will see the supercarrier sail to the eastern coast of the United States to begin trials that will pave the way for the UK to operationally deploy fighter jets at sea for the first time in years.

This is the culmination of years of training, tests and trials. Last year, British personnel embarked on the USS America week for at-sea developmental testing phase 3 (DT3), the last trial that paves the way for the US Marine Corps to deploy the jet operationally on amphibious assault ships.

BAE Systems test pilot Pete Wilson said:

“This will not be a DT phase. Testing on the Queen Elizabeth will be like DTs 1, 2 and 3 combined. We don’t need to use fully instrumented aircraft; we already understand most of the loads on the aircraft systems, as we have tested that during earlier tests.”

The aircraft that will be landing on the supercarrier will belong to the Joint Operational Test team. The team’s mission is to build confidence in the aircraft towards helping clear the F-35 to make the legally mandated advance from Low Rate Initial Production to Full Rate Production. The RAF’s No 17 (Reserve) Test and Evaluation Squadron comprises ten percent of the test program in the JOTT we understand.

The reason that most if not all of the aircraft to touch down will be American isn’t some scandalous outrage (just watch how some papers report this, though) but rather most of the F-35Bs in Joint Operational Test team are American.

After speaking to one of the pilots in the test programme, we understand that the UK only has three (BK1, 2 & 4) test jets that are “orange wired” to take data for post-flight analysis, the rest being operational aircraft. Therefore, it is highly likely that the jets to go on HMS Queen Elizabeth later this year will be “mostly, if not entirely, American but flown by UK pilots”.

We were told by one of the UK pilots currently flying the jet that the reason for this is that the JOT team dictate the availability of test jets out of a pool. Our contact said:

“It would be nothing more than symbolic to make UK jets available for the trials and that comes at a significant effort since all of them are based at Edwards AFB in California, not on the East Coast where the ship trial is due to take place.

Therefore, the most obvious and cheaper choice is to use the F-35B test jets based at Pax River, which are US ones. British test pilots like Andy Edgell, Nath Gray, will obviously fly them but there’ll be US pilots too because that’s how Joint Test works.”

HMS Queen Elizabeth is expected to sail any day this week.
