After Trump's Twitter attack, F-35 jets lose face over delivery delay

F-35 aircraft is the most costly plane in history with development & acquisition price tag of $379 bn for 2,443 jets

The US F-35 stealth fighter programme suffered a dual blow on Monday as President-elect Donald Trump blasted "out of control" costs and bad weather delayed delivery to Israel by six hours.

With US Defence Secretary Ashton Carter in Israel for the arrival of the first two of 50 of the warplanes bought from aerospace giant Lockheed Martin, Trump lashed out on Twitter against the programme.

Lockheed Martin's stock tumbled 4.3 per cent shortly after the tweet, which prompted a response from the company.

With a current development and acquisition price tag of $379 billion for a total of 2,443 F-35 aircraft -most of them destined for the US Air Force -the plane is the most expensive in history.

Once servicing and maintenance costs are factored in over the aircraft's lifespan through 2070, overall programme costs are expected to soar to $1.5 trillion.

Speaking at the landing site in southern Israel, Jeff Babione, Lockheed's programme manager for the F-35s, told journalists the planes represented a good deal.

"It's of great value and I look forward to any questions that the president-elect may have," he said.

In Israel, the first two F-35s landed at Nevatim air base at around 8.15 pm (1845 GMT), around six hours late after being delayed by bad weather in Italy, believed to be fog.

Some 4,000 people had been expected to watch the landings but the crowds thinned as the landing was delayed, leaving only around half the seats full by nightfall.

The two planes came to a halt in front of the spectators, one on each side of the stage erected for speeches of welcome.

"The aircraft landing here will change the rules of the game," President Reuven Rivlin said.

Prime Minister Benjamin Netanyahu referred to Israel's air force as the state's long arm.

I want to tell the people of Israel today (Monday) that this long arm became longer, more powerful," he said.

"Anyone thinking of attacking us will be attacked," he added, in an apparent reference to arch-foe Iran. "Anyone thinking of destroying us places his own existence in danger."

A Lockheed official said the delivery delay was caused by Italian air safety regulations, rather than any limitation of the planes, but this did not stop jibes.

The Trump attack and the delay in the fighters' arrival threatened to overshadow what Israel had labelled a key day in its military's future.

While other countries have ordered the planes, Israel, which receives more than $3 billion a year in US defence aid, says it will be the first outside the US with an operational F-35 squadron.

Carter and Israeli Defence Minister Avigdor Lieberman joined Netanyahu and Rivlin at the ceremony.
