Other Navies
The Royal Navy deploys Tomahawk missiles for land-attack on all its present fleet submarines (the Trafalgar and Astute classes), although these are multi-roled boats rather than having land attack as a primary role. Formerly, some submarines (e.g. of the Swiftsure class) also carried Sub-Harpoon anti-ship missiles.
The Collins class submarines of the Royal Australian Navy, which can launch Sub-Harpoon anti-ship missiles, use the SSG designation.
The Israeli Dolphin class submarine fleet is alleged to carry both nuclear armed Popeye Turbo SLCMs with a range of at least 1,500 km (930 mi) as well as Sub-Harpoon missiles.
