A U.S. Navy investigation to assess the circumstances surrounding the USS Guardian (MCM 5) grounding that occurred in Philippine waters will include information on faulty digital navigation chart data that misplaced the location of Tubbataha Reef.
Last Friday, the U.S. National Geospatial-Intelligence Agency provided the Navy preliminary findings of a review on Digital Nautical Charts that contain inaccurate navigation data and may have been a factor in the Guardian grounding that occurred in the Sulu Sea on Jan. 17 Philippine time.
"While the erroneous navigation chart data is important information, no one should jump to conclusions," U.S. Pacific Fleet spokesman Capt. Darryn James said. "It is critical that the U.S. Navy conduct a comprehensive investigation that assesses all the facts surrounding the Guardian grounding."
