We know that the Red Sea is famous for its world's hottest and saltiest seawater. It is also the most heavily traveled waterways as well. From the 18th to 19th century, many shipwrecks were discovered in the Red Sea. This shipwreck was discovered in 1988 and it is called the "Russian Wreck". According to experts, it might be a fishing trawler called Khanka.
It is believed that Russians used fishing trawlers for other purposes than just fishing such as surveillance. Given that this ship had some advanced equipment used for communication, it is believed that it was a spy ship.
