More than 50 IRGCN and Iranian Navy personnel were killed, while the US lost one SeaCobra helicopter and its two crew members. After all, Iran has made significant changes to its naval forces and tactics over the past 35 years, becoming "much more asymmetric," according to Bryan Clark, a senior fellow at the Hudson Institute and expert on naval operations. Iran's naval force now consists of the Islamic Revolutionary Guard Corps Navy, known as the IRGCN, and the regular Iranian Navy, Clark told Insider. The Iranian Navy still primarily consists of frigates and corvettes, which operate outside the Gulf, and is much more like other conventional navies.
