170404-N-WV703-020 CHANGI NAVAL BASE, Singapore (April 4, 2017) Sailors aboard the littoral combat ship USS Coronado (LCS 4) observe the aircraft carrier USS Carl Vinson (CVN 70) as it makes port at Changi Naval Base. Coronado is a fast and agile warship tailor-made to patrol the region's littorals and work hull-to-hull with partner navies, providing U.S. 7th Fleet with the flexible capabilities it needs now and in the future.
