Sansha City is located on Woody Island. Woody Island has had two or three artificial harbors capable of docking vessels up to 5,000 tonnes. In 2008, the island's main sea transport was the freighter
Qiongsha-3, (2,500 tonnes, 84m x 13.8m, 200 passengers and 750 tonnes of cargo); it was the only means of sea transport for non-military personnel such as fishermen and researchers. Each trip from Hainan to Woody Island lasted from 13 to 15 hours. In 1990, Chinese authorities built a runway and airport on the island. The
Sansha Yongxing Airport was completed in July 1990, with a 2,700-metre runway that is capable of handling any
fourth generation fighter aircraft of the
PLA Naval Air Force such as the
Chengdu J-10AH,
Shenyang J-11BH,
Xian JH-7A, and
Sukhoi Su-30MK2. Other constructions include three main roads and an 800-metre long concrete causeway connecting to
Rocky Island (石岛/đảo Đá). Apart from government buildings and army posts, the island has various establishments. The island's administrative centre is located on Beijing Road, which has an
Industrial and Commercial Bank of China branch, a hospital, various shops, hostels, food stations, a post office, small department stores and an aquatic company. A rescue centre was established on 15 July 2006. There are two museums on the island – Xisha Maritime Museum and a Naval Museum. Other monuments include towers left by the
Imperial Japanese Army during WWII, a monument erected by the ROC government in 1946, and a monument erected by the PRC in 1974. Visitors to the island are required to obtain approval from PRC authorities in
Haikou before departure. Hiring a fishing boat from
Hainan to the island is possible. On 10 April 2011,
China National Radio (CNR) and Hainan People's Broadcasting Station began
FM broadcasts on the island. This is in addition to mobile communications and satellite television which are available in the fishing villages of the Paracel Islands. China began construction on a school to serve about 40 children whose parents work on the island in June 2014, with construction expected to cost about 36 million yuan and take a year and a half. On 17 February 2016, the New York Times reported that an
HQ-9 Surface to Air Missile system had been deployed on the island. In July 2016, it was reported that
Shenyang J-11BH fighter aircraft were deployed on the island. In April 2017, the Asia Maritime Transparency Initiative – a US think tank based in Washington – reported that a Shenyang J-11BH fighter aircraft was spotted on the island in satellite photos taken on 29 March 2017. On 22 July 2017, over 200 Chinese moviegoers attended a screening in a theater built on the island by the Hainan Film Company with up-to-date technology, including both
4K resolution and a 3-D perforated screen. In May 2018, based on
PLA Air Force defence circulars and Chinese social media posts, the Washington Post and Washington based Asia maritime transparency initiative reported that China had landed long range
bombers on the island as part of a defense exercise. In August 2020 the PLA Air Force deployed
H-6J bombers to Woody Island. ==Ecology and resources==
