WASHINGTON - The US Department of State has approved the potential sale of 720 Stinger missiles to Egypt for $740 million, the Pentagon said on Tuesday.

Egypt would put the Stingers on vehicles equipped with the Avenger launcher system versus a shoulder-fired launcher.

The principal contractor will be RTX Corp, the Pentagon said.

This summer several NATO members placed an order for nearly $700 million worth of the missiles. That order extended the production lines' order backlog through 2029. Egypt's order adds to that.
