The jets landed on Sunday evening, their arrival delayed by bad weather on the flight from USA to England, and then onward to Finnish air space.
The next #HX candidate to participate in the #HXChallenge is Lockheed Martin F-35A Lightning II. Two F-35As arrived at Pirkkala Air Base tonight on 9 February. #ilmavoimat #finaf #comcamfi pic.twitter.com/ilpwfn7dSk— Ilmavoimat (@FinnishAirForce) February 9, 2020
Four F-35s initially left Luke Air Force Base in Arizona on 5th February and headed east but refueling tankers couldn’t support the mission across the Atlantic due to the weather conditions, and just two jets ended up in Pirkkala.
We're excited to be in Finland alongside @billieflynn and the entire @LockheedMartin team to showcase the capabilities of the #F35 during the #HXChallenge. #F35inFinland #hxhanke #hx pic.twitter.com/r1eqviBjrw— F-35 Lightning II (@thef35) February 10, 2020
“We’re thrilled to be able to show what the F-35 can do, its amazing capabilities, and what it will be like as part of the future of the Finnish Defence forces now, and for the many decades to come” says Lockheed Martin test pilot Bille Flynn in a short video posted to social media.
What’s happening at Pirkkala Air Base?
The aircraft will take part in simulated long-term war games, where the candidate jets will play their roles as part of Finland’s defence systems. In the simulated battles they’ll face the Air Force’s current F/A-18 Hornets and Hawk jet trainers.
The Air Force says the event is taking place in Finland so that each plane can be tested under Finnish winter operating conditions – and also to provide a balanced evaluation for each of the five candidate aircraft.
The other contenders taking part in ‘Operation HX Challenge’ are France’s Rafale; the Eurofighter’s Typhoon; Boeing’s F/A-18 Super Hornet; and Sweden’s Saab Gripen.
Day #4. Groundhog Day! Waiting for refueling tankers and the big winter storm. 2 former CF18 Canucks can handle winter storms but we do need gas! Look forward to more white stuff at #HXChallenge and Finland. #F35KnowsCold pic.twitter.com/i3hHhVuUOE— Billie Flynn (@billieflynn) February 6, 2020
Although all the aircraft are designed to operate in sub-zero temperatures, the Air Force says when temperatures hover around zero with snow, sleet or freezing drizzle, it throws up extra challenges for the jets.
Harsh weather conditions can have an impact on the performance of electro-optical sensors in particular.
