F-35B conducts Shipborne Rolling Vertical Landing on HMS ‘Queen Elizabeth’

-

The first ever Shipborne Rolling Vertical Landing ( SRVL) was recently carried out with an F-35B conducting trials onboard the new British aircraft carrier, HMS Queen Elizabeth. The UK is the only nation currently planning to use this manouvere, which allows jets to land onboard with heavier loads, with no need to jettison fuel and weapons before landing.

The F-35Bs have conducted vertical landings, coming to a hover to the side of the ship, translatin­g sideways over the deck, before gently lowering to land, regarded as a “safer method” to reduce speed before the jet lands in this way, rather than landing on at speed and coming to a stop before it runs out of deck.

An SRVL uses a different approach, with the jet using a more convention­al landing pattern, approachin­g the ship from the aft end at speed, using the thrust from the nozzle and lift created by air over the wings, to touch down and come to a stop as soon as possible.

The first SRVL was conducted by Peter Wilson, a BAE Systems test pilot with the F- 35 Pax River Integrated Test Force, which took place on 13 October 2018, off the US east coast. Landing 755 yards back from the end of the carrier’s ski jump, the jet came to a complete standstill at the 580 yard mark.

“I’m thrilled to have achieved this, the whole team is,” Wilson said. “It’s an inherently risky manouvere. We have always understood it is safer to stop before you land than it is to land before you stop and the prime reason for that is that if something goes wrong with the airplane it is far better for it to be stationary than a rolling wreckage. I’ve worked on this for the past 17 years; it’s fantastic to know that it’s matched the modelling and simulation we have done over the years. I’ve flown over 2,000 SRVLs in the simulator, and am honoured to have been able to do the first one onboard HMS Queen Elizabeth here today.”

Royal Navy Lt. Christophe­r Mould had the role of Landing Safety Officer (LSO) during Wilson’s flight. Taking his place in a packed, but eerily silent FLYCO (Flight Control), Mould was the final say as to whether the jet could land. With seconds to go before touchdown, his call of “happy” allowed the historic landing to take place.

“I’ll admit, I was nervous; it was a pretty intense experience,” Mould recalled. “It’s the first time we’ve ever done it. As the independen­t checker, I have to make sure that what we are seeing in FLYCO, is also what the pilot is seeing and call it as I see it.”

His test pilot colleague onboard, U.S. Marine Corps Maj. Michael Lippert from F-35 Pax River ITF, said that “America was watching this part of the trials onboard the carrier particular­ly closely.” The USMC, which also flies the F-35B variant, will join the ship when she deploys operationa­lly for the first time in 2021. “This is one of the main reasons we are here. It is of interest to the Service at large – we are learning from each other,” Lippert said. “I will have the honour of conducting the first SRVL at sea for the US military, so I’m excited; it’s what we all join up for. This is truly experiment­al test flying.”

Royal Navy Commodore Mike Utley, Commander U.K. Carrier Strike Group onboard stated “What today’s milestone eventually means is that we will give our strategic leaders even more choice. Pushing this ever expanding envelope means we can achieve the effects they require from us. Yet again we have demonstrat­ed the seamless cooperatio­n between the UK and US, but more essential than that, is how it will translate into future operations.”

For HMS Queen Elizabeth’s First of Class Flight Trials Lead Test Pilot, Royal Air Force Squadron Leader Andy Edgell, the first SRVL was the culminatio­n of two years’ work and described the emotional moment. Edgell, who is also a test pilot at the F-35 Pax River ITF stated: “I’m feeling an enormous release, two years of concern— have we missed anything? What did we not consider? It’s overtaken our lives, to make sure the outcome today was perfect. It couldn’t have gone better and it was obvious to anyone, we were watching a moment in history being made for Royal Navy aviation. Now we will focus on putting all four of our test pilots here through the same process to achieve the widest breadth of data possible.”

HMS Queen Elizabeth continues the Westlant 18 deployment, along with escorts Type 23 frigate HMS Monmouth and Arleigh Burke- class destroyer USS Lassen. She also has embarked Merlin Mk 2 anti-submarine helicopter­s from Naval Air Squadron 820 from RNAS Culdrose, and Mk 4 Merlins from Naval Air Squadron 845 at RNAS Yeovilton for conducting Search & Rescue and Helicopter Delivery Services.
