Terror-targeted JFK Airport has become a giant slumber party for some of its security guards — who regularly doze on duty at key posts, according to a former boss and damning photos obtained by The Post.

Although the airport has been at the center of at least one terror plot — and an embarrassing security snafu involving a jet skier last summer — these disturbing infractions seem to mean little to the cadre of guards who catnap on the job, says the ex-boss, Stephen Jackson, 39.

“It was a regular occurrence finding the guards sleeping,” said Jackson, a former manager for FJC Security, which employs about 300 security guards at JFK Airport.

Jackson, an ex-Marine, began working at FJC in August 2011 and became a security-guard supervisor at JFK in December. He was fired May 28 after what he calls a campaign of harassment over everything from his whistle-blowing to his being Hispanic.

The married Staten Island father of four said he typically supervised between 58 and 65 guards over an eight-hour shift at JFK — and regularly caught about six sleeping on duty.
