HMS Queen Elizabeth recently departed her home port bound for the United States in trials that will see her land fast jets on deck for the first time.

The ship will conduct trials in UK waters over the coming days, before departing for the United States.

The deployment, known as ‘WESTLANT 18’, will be the first-time HMS Queen Elizabeth will have sailed across the Atlantic. As well as the vital deck trials, the Royal Navy say it will also involve exercises to prove the ability to operate with other nations’ maritime and aviation assets, as well as the landing of Royal Marines and their equipment ashore in the United States, to conduct training with their US counterparts.

The Royal Navy add that the carrier will be joined by RFA Tiderace and Type-23 Frigate HMS Monmouth, as well as Merlin Mk2 helicopters from 820 Naval Air Squadron, RNAS Culdrose, Mk 4 Merlins from 845 Naval Air Squadron, RNAS Yeovilton and a contingent of Royal Marines from 42 Commando, Plymouth.

It is understood that around 200 trials support staff will be joined by two ‘orange wired’ F-35 test aircraft, belonging to the Integrated Test Force (ITF), which are expected to conduct 500 take offs and landings during their 11-week period at sea.

After speaking to one of the pilots in the test programme, I was informed 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”.

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.

I was 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.”

The aim of these initial, or ‘developmental’ trials are to ascertain, through the specially equipped aircraft and sensors around the ship, the operating parameters of the aircraft and ship, in a range of conditions. Similar successful trials were conducted by HMS Queen Elizabeth at sea earlier this year for Rotary Wing aircraft.

Four F‑35B Lightning developmental test pilots will embark to fly the aircraft; three British, one American. The British personnel comprise a Royal Navy Commander, a Squadron Leader from the Royal Air Force and one civilian test pilot. They will be joined by a Major from the US Marine Corps.

HMS Queen Elizabeth Commanding Officer, Capt Jerry Kyd said:

“This deployment to the United States will be another first for my ship. Crossing a major ocean with 1500 sailors, aircrew and Marines embarked and the spectacle of the first F-35B Lightning landing on the deck in September is very exciting for us all. It has been an incredible journey since we left Rosyth just over a year ago and we are all looking forward to this next, seminal chapter in HMS Queen Elizabeth’s life.”

This deployment 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.”

As the ship’s work-up continues, so too does the regeneration of the UK’s Carrier Strike capability. Commander UK Carrier Strike Group (COMUKCSG), Cdre Andrew Betton, will take command of the ship and other units of his task group, embarking in HMS Queen Elizabeth with his Carrier Strike Group headquarters staff.

He said:

“As a critical step towards delivering the UK’s new Carrier Strike Group, this deployment demonstrates the astonishing collaborative effort that will enable the new F-35 jets to fly routinely from our Queen Elizabeth class aircraft carriers.

At the heart of the Maritime Task Group, the aircraft carrier is well protected and sustained, ready to operate around the world as a potent and exceptionally flexible instrument of our foreign policy. These first F-35B embarked trials in a UK aircraft carrier are not only key to future operational success, but represent an iconic moment for the modern Royal Navy.”
