Lockheed Martin Corp. has solved a major flaw with the U.S. Marine Corps’ new King Stallion helicopter that threatened to undercut congressional support for the $31 billion program.

The Lockheed-led project “has successfully tested a modification to the aircraft’s exhaust system” to solve the problem of hot engine exhaust being sucked back into one of the aircraft’s three engines, Megan Wasel, a spokeswoman for the Naval Air Systems Command, said in an email on Monday.
