Vietnam War, the Falklands War and the Gulf War. With their multi-role capabilities, these vessels have also proven extremely useful in civil emergencies, providing humanitarian aid and disaster relief at times of natural disasters, and for peace-keeping duties providing logistical support for internally displaced persons (IDPs), and this capability is often factored into tender requirements during procurement processes (and which can be helpful at justifying the need for these vessels to politicians). Examples of vessels of other classes that have undertaken multiple roles for which a JSS is intended to fulfil include: In 1988, , an LPH of the RN, provided humanitarian aid to victims of Hurricane Mitch in Honduras and Nicaragua. In 2012 the vessel was moored on the River Thames at Greenwich to providing logistics support, accommodation and a secure helicopter landing site for the London Olympic Games. From December 2001 to March 2002 , a landing platform amphibious (LPA) ship of the Royal Australian Navy (RAN), deployed to the Persian Gulf and conducted boarding parties to inspect ships transiting the waters for compliance with sanctions against Iraq, and served as the forward operating base (FOB) for US Navy SEAL teams. In 2003 the vessel returned to the Gulf where it operated as a command and control ship during the invasion of Iraq, as well as providing logistical support to other coalition vessels in the conflict. The ship has also provided disaster relief and humanitarian aid in South East Asia and the Oceania region, including the 2004 Boxing Day Tsunami. In 2020 , a LPD of the Indian Navy was used to retrieve Indian nationals stranded in the Maldives during the COVID-19 pandemic. Various vessels of the USN's landing platform helicopter (LPH) ships have been used for purposes other than amphibious and airborne landings, including: In 1962 USS Iwo Jima operated as a control ship during the Operation Fishbowl nuclear tests at Johnston Atoll and evacuated and later return non-essential personnel to and from the site between 1963 and 1971 numerous vessels of this class operated off the coast of Vietnam where their duties included mine countermeasures, search and rescue operations, underway refuelling of other task force ships, and with their 100-bed hospitals were often the primary receiving station for wounded personnel Between 1970 and 1972 five vessels of this class functioned as recovery ships for NASA's Apollo manned lunar program, including Iwo Jima which recovered the crew
