President Trump announced Sunday that a huge cache of desperately-needed coronavirus-fighting supplies has landed in New York.

The first flight in the FEMA project dubbed “Project Airbridge” landed at John F. Kennedy International Airport with 2 million masks and gowns, more than 10 million gloves and 70,000 thermometers that will go to New York, New Jersey and Connecticut.

The Federal Emergency Management Agency is working with private companies on the initiative to “expedite the movement of critical supplies from other countries to the United States,” the president said.

FEMA has scheduled 19 additional flights, and hopes to have about 50, Trump said at the press conference — where he also announced that federal social-distancing guidelines would be extended to April 30.

State and city leaders, including New York Gov. Andrew Cuomo and Mayor Bill de Blasio, have been pleading with the federal government for more supplies of ventilators and masks for healthcare workers amid a widespread shortage.

In an appearance on Fox News’ “Hannity,” Friday, Trump suggested that New York won’t need the 30,000 ventilators that Cuomo has said will be necessary when virus cases peak in the state.

Trump on Sunday suggested that some hospitals were stockpiling with the equipment.

“We have some healthcare workers, some hospitals … hoarding equipment including ventilators,” Trump said. “We have to release those ventilators — especially hospitals that are never going to use them.”

He said of one unspecified New York hospital, “How do you go … from 10 to 20,000 masks to 300,000? Even though this is different. Something is going on, and you ought to look into it as reporters. Are they going out the back door?”

“I want the people in New York to check — Gov. Cuomo, Mayor de Blasio … I would like them to check that, because I hear stories like that all the time,” he added later.

The president also praised FEMA and the Army Corps of Engineers for building an “incredible” 2,900-bed hospital in New York’s Javits Center. He said they are now moving to other states to build hospital beds, including New Jersey and Louisiana.

“It’s an incredible complex, top of the line hospital,” Trump said. “They did it so quickly. Everyone is trying to figure out how they did it, including me — and I was a good builder.”

And he noted the grim scenes playing out at hard-hit Elmhurst Hospital in his native Queens.

“I’ve been watching that for the last week on television,” he said. ”Body bags all over, in hallways. I’ve been watching them bring in trailer trucks — freezer trucks, they’re freezer trucks, because they can’t handle the bodies, there are so many of them. This is essentially in my community, in Queens, Queens, New York.”
