Iran likely to reverse-engineer captured US underwater drone

Iran recovered a U.S. autonomous underwater drone and says it will study it, while U.S. officials say it was an older, non-sensitive model.
Iranian embassies gloated on social media, mocking the U.S. and joking about reverse-engineering the craft.
The episode is an awkward PR and tech setback for Washington, highlighting the risks when advanced drones end up in rival hands.
