ARLINGTON, Va. — The attack on two U.S. warships in Jordan was not the result of a Navy security lapse, a Navy official said Thursday.

On Aug. 19, terrorists fired rockets at the USS Ashland and Kearsarge while the two ships were at pier in Aqaba, Jordan.

No disciplinary action is pending in connection with the attack, said Lt. Cmdr. Charlie Brown, a spokesman for 5th Fleet, based in Bahrain.

“There is no way to make sure any force protection is 100 percent guaranteed. We’re going to increase force protection measures, but we’re not going to allow terrorists to dictate future actions,” Brown said.

Jordanian officials continue to investigate the attack, he said.

“The fact is we’re conducting operations and exercises in a region of the world that can be a dangerous place,” Brown said.

The Jordan attacks come almost five years after the October 2000 terrorist attack on the USS Cole that killed 17 sailors.

Since then, the Navy has changed its security measures, causing the terrorists to change tactics, a Navy official said Wednesday.

In the aftermath of the Cole attack, the Navy has seen a spike in numbers of Masters At Arms, tasked with keeping ships safe, said Navy Capt. Tim Sprague, branch head of anti-terrorism.

Before the Cole attack, the Navy had about 2,000 Masters at Arms, but now that number is 9,700 and the Navy expects to have more than 11,000 Masters at Arms by 2008, said Navy spokesman Lt. Trey Brown.

Masters at Arms make up the core of mobile security forces established after the Cole attack that set up tight perimeters around ships, Sprague said.

“Nothing will get inside that perimeter without their knowledge and without their permission,” he said.

Sprague said terrorists adjust to improvements in security, so the Navy randomly changes its security procedures.

“We try to keep them guessing with what we’re going to do,” he said.

Since the attack on the Cole, the Navy and law enforcement share intelligence from the Naval Criminal Investigative Service’s Multi-Threat Alert Center in Washington, said Elmer Roman, a science adviser to the Navy and NCIS.

Sprague said communication is open among all elements of force protection.

“There are no secrets here. We share information and by sharing information we get smarter and we get better,” Sprague said.
