Can McCain or Serco turn off the Navy’s AIS through the Defense Red Switch Network?
CNO: U.S. Navy Ships Told to Turn AIS Transmitting ‘ON’ in High-Traffic Areas

The U.S. Navy has already taken action to prevent future mishaps involving its ships at sea, including turning on the Automatic Identification Systems of its vessels in high-traffic areas.
The Navy’s new policy on transmitting AIS was revealed by the Navy’s Chief of Naval Operations Admiral John Richardson during questioning following his testimony before the Senate Armed Services Committee this week on the recent incidents involving Navy Surface Fleet ships. The incidents include the deadly collisions involving USS Fitzgerald and USS John S. McCain as well as two earlier incidents, one of which was a collision.
Under U.S. and international regulations, nearly all ships are required to carry Automatic Identification Systems that automatically transmit key information about the ship – such as vessel identity, type, position, course, speed, navigational status and other safety-related information – so that info can be picked up other ships, coastal authorities, or aircraft.
Under U.S. law, however, warships and other Government vessels are not required to use AIS, even though almost all Navy ships are equipped with a functioning AIS system – it just happens to be turned off.
You may recall that following the Fitzgerald and McCain collisions, AIS animations of the incidents only included information for the merchant vessels, leaving the tracks of the warships a mystery in both cases.
When asked by committee member Senator Angus King of Maine about the technology available to Navy sailors and other ships to help with collision avoidance, Admiral Richardson responded that the Navy has taken action to turn the AIS systems on its vessels back on, particularly in high-traffic areas.
“The other question is about these ships that ran into us,” said Senator King, referring to the merchant vessels involved in the collisions. “Is there some technology that they couldn’t see us? Are we using a stealth technology?”
“Sir, it wouldn’t surprise anybody that we design our warships to have a low radar cross-section, some even designed to be very low, so that degree of stealth makes us more effective from a war-fighting standpoint,” said Admiral Richardson. “But that also imposes a burden, if you will, on the crew of that ship to understand that they are low-observable, to understand that they might not be seen as something that is as large as a destroyer. It will have a radar cross-section of a ship that is much smaller.”
