The Pentagon’s top testing official has weighed and measured the F-35 and found it wanting.

The F-35 Joint Strike Fighter program, the most expensive military program in the world, is even more broken than previously thought. The jet can’t tell old parts from new ones, randomly prevents user logins, and trying to eject out of it will likely result in serious neck injury and maybe death. A Pentagon office is warning that the plane is being rushed into service.

The Pentagon’s office of testing and evaluation on Monday released a report detailing dozens of major problems, or “deficiencies” with the aircraft. The report follows the release of a December memo by Michael Gilmore, the Department of Defense’s director for Operational Test and Evaluation, or OT&E. The report goes on to question the logic of pushing other governments to purchase large blocks of the aircraft until the issues are fixed.

So what’s wrong with the F-35?  Below are some of the report’s key findings.

The Version That the Marines Are Using Is Very Buggy

The Marines rushed to finish testing their version of the aircraft in May of 2015 in order to declare initial operating capability by July. The report describes serious problems with the computer software, (the Block 2B version of the software) in the Marines’ F-35 variant. Those software problems include “in fusion, electronic warfare, and weapons employment result[ing] in ambiguous threat displays, limited ability to respond to threats, and a requirement for off-board sources to provide accurate coordinates for precision attack.”

After the report came out Monday, Lt. Gen. Chris Bogdan, of the F-35 program executive office, issued a statement to cast the report’s findings in a rather more flattering light. “Once again, the annual DOT&E report points out the progress being made by the program,” the statement read, as though responding to a different report altogether. “This includes the U.S. Marine Corps declaring Initial Operational Capability (IOC) in July 2015. The USMC declared IOC with Block 2B software because it provides increased initial warfighting capability. Marine F-35s have the necessary weapons to conduct close air support, air interdiction and limited suppression/destruction of enemy air defense missions.”

ALIS Is Still Terrible, Perhaps Even Getting Worse

In a 60 Minutes segment, reporter David Martin in 2014 made famous problems with one of the  F-35’s key computers, the Autonomic Logistics Information System, or ALIS, the internal diagnostic system on the plane that was supposed to keep track of the health of virtually every part. The system was heavily resistant to human overrides. After the segment aired, the Joint Program Office claimed that the override issues had been fixed.

Unfortunately, ALIS’s various updates have left many of the old problems intact and added new ones, according to the report. “Each new version of software, while adding some new capability, failed to resolve all the deficiencies identified in earlier releases,” it states.

Lockouts, Confusion, etc.

What forms do these bugs take and what can they do the plane? Here a few of the more alarming finds:

  • The F-35 doesn’t know its new parts from old parts. The computerized maintenance management System, or CMMS, “incorrectly authorizes older/inappropriate replacement parts.”
  • The F-35 fails to detect  if it’s been flying too fast or what effect that might have. “The Integrated Exceedance Management System, designed to assess and report whether the aircraft exceeded limitations during flight, failed to function properly.”
  • The plane “randomly prevented user logins.”
  • The plane doesn’t know how broken broken parts are: “The maintenance action severity code functionality…designed to automatically assign severity codes to work orders as maintenance personnel create them—did not work correctly.”
  • The plane’s crews need to phone Lockheed Martin tech support because the plane can’t handle the data it needs to process in order to run missions. “Managing data loads associated with mission planning required extensive contractor support.”
