The Australian Future Submarine Class is an as-yet unnamed class of 'at least 8' submarines[1] to replace the Collins-class submarine for the Royal Australian Navy.[2] This program supersedes the Attack-class program, following an announcement by Australian Prime Minister Scott Morrison that all 12 submarines, built by French shipbuilder Naval Group, will be scrapped in favour of a new nuclear-powered design, likely based on either the Royal Navy's Astute-class or United States Navy's Virgina-class[2].
