F-35's Latest Glitch: Fighter Jet Can't Fire A GunUntil 2019 LMT - Investors.com

The F-35 has state of the art stealth features, but won't be able to fire a gun for four more years, according to reports.

Lockheed Martin's (NYSE:LMT) F-35 is expected to enter combat with the Marine Corps in 2015 and Air Force in 2016. But the software on the high-tech fighter jet isn't capable of shooting the 25mm cannon on board. Officials from the Air Force told the Daily Beast that the software support won't be finished until 2019.

The plane will still have weapon capabilities, including two Raytheon (NYSE:RTN) long range air-to-air missiles and two bombs, according to the report.

The weapon software issues are the latest in a series of setbacks for the overbudget and behind-schedule plane — the world's most expensive weapon program ever.

"To me, the more disturbing aspect of this delay is that it represents yet another clear indication that the program is in serious trouble," said an Air Force official cited by the Daily Beast.
