US Navy warships have been involved in four major accidents in the Asia-Pacific this year, including three collisions with civilian vessels.
First in January the guided-missile cruiser USS Antietam ran aground while trying to anchor in Tokyo Bay. Then in May the guided-missile cruiser USS Lake Champlain was struck by a South Korean fishing boat off the coast of Korea.
Next month the destroyer USS Fitzgerald was struck by a gigantic container ship in crowded waters off the coast of Japan. 7 US sailors were killed and the ship seriously damaged.
Finally last month the destroyer USS John S. McCain was struck by a massive tanker near Singapore port, killing 10 sailors aboard the American vessel.
"There's something more than just human error going on because there would have been a lot of humans to be checks and balances," Jeff Stutzman, an ex-information warfare specialist in the Navy, who now works at a cyber threat intelligence company, told McClatchyDC.
"When you are going through the Strait of Malacca, you can't tell me that a Navy destroyer doesn't have a full navigation team going with full lookouts on every wing and extra people on radar," he said.
Itay Glick, the founder of cyber security firm Votiro, told news.com.au that the possibility of cyber interference was the first thing that came to his mind when he heard about the incident.
"I don't believe in coincidence," Glick told the website.
The US Navy itself fed the speculation by confirming it was investigating the possibility of a cyber attack, though it admitted it had no reason to suspect one.
