The U.S. Navy aircraft carrier Abraham Lincoln is due to dock at nearby Laem Chabang on Wednesday with two accompanying Navy vessels, bringing nearly 5,000 sailors and Marines to Pattaya after more than 200 days at sea. Thai officials expect the port call to provide a short-term economic boost, with Pattaya Mayor Poramase Ngampiches estimating daily spending of 1,000 to 3,000 baht ($30 to $91) per U.S. military personnel, depending on time ashore and overnight stays. Authorities are also adding patrols around the beachfront and nightlife district after weekend raids detained 40 to 50 people suspected of prostitution. Prostitution is illegal in Thailand, although the sex industry remains visible in tourism centers including Pattaya and parts of Bangkok. Officials and tourism representatives said the commercial impact would depend on where sailors spend their time, including whether they travel to Bangkok. Researchers warned that a surge in customers could increase sexual exploitation and sexually transmitted diseases, while reports of suicide attempts and falling morale aboard the carrier have added concern. The Lincoln left San Diego in November and was later redirected to the Middle East to support military operations in the U.S.-Israeli war with Iran; Democratic lawmakers said the deployment set a modern-day record for consecutive days at sea.
