The South African Navy (SA Navy) fleet consists of approximately 60 commissioned vessels as of 2026. Its core combat capability is centred on four stealth guided-missile frigates and three diesel-electric attack submarines. Amphibious and support capability is provided by a combat support ship, a hydrographic survey vessel, mine countermeasure vessels, and a growing fleet of inshore and offshore patrol vessels, supported by harbour and seagoing tugs. Numerous smaller auxiliaries and craft, including rigid-hulled inflatable boats (RHIBs), also remain in service but are not listed.
The SA Navy has operated six submarines and nine strike craft throughout its history. The three Daphné-class submarines were retired during the early 2000s following the introduction of the Heroine class, while the Warrior-class strike craft, which served as the Navy's principal surface combatants during the late apartheid era, were gradually withdrawn from frontline service following the commissioning of the Valour-class frigates.
The majority of the fleet is based at Naval Base Simon's Town near Cape Town in the Western Cape, which serves as the Navy's headquarters, principal dockyard and main operational base. Naval Base Durban functions as a forward-operating facility for patrol vessels and mine warfare units.
Submarines Heroine class
South Africa operates a single class of diesel-electric attack submarines, the Heroine class, comprising three boats commissioned between 2005 and 2008. Based on the German Type 209/1400MOD design, the submarines were constructed by Howaldtswerke-Deutsche Werft (HDW) and Thyssen Nordseewerke in Germany to meet South African Navy requirements. Acquired under Project Wills as part of the Strategic Defence Package, they replaced the ageing French-built Daphné-class submarines and restored South Africa's submarine capability. Their introduction made South Africa one of only three African nations, alongside Algeria and Egypt, to operate an active submarine fleet, and the only country in sub-Saharan Africa with an operational submarine arm.
Designed as highly capable hunter-killer submarines (SSKs), the Heroine class provides the SA Navy with anti-surface, anti-submarine and intelligence-gathering capabilities, while also supporting special forces insertion, covert surveillance and maritime reconnaissance. Each submarine is fitted with eight 533 mm bow torpedo tubes capable of carrying up to 14 Atlas Elektronik SUT 264 heavyweight torpedoes or optional UGM-84 Sub-Harpoon anti-ship missiles, although the latter capability has never been introduced into service. Equipped with advanced sonar, electronic warfare and combat management systems, the class is optimised for stealth, long-endurance patrols and operations across the Atlantic and Indian Oceans.
The submarines are currently undergoing phased refits and life-extension work following years of deferred maintenance, with work on SAS Charlotte Maxeke and SAS Queen Modjadji commencing in late 2025 under the SA Navy's long-delayed submarine sustainment programme. All three vessels are expected to remain in service until around 2038–2040, although no formal successor programme has yet been announced. Despite ongoing funding constraints, the Heroine class remains the most strategically significant capability in the SA Navy, providing South Africa with the only submarine force in sub-Saharan Africa.

Frigates
Valour class
South Africa operates a single class of stealth guided-missile frigates, the Valour class, comprising four vessels commissioned between 2006 and 2007. Based on the German MEKO A-200SAN design, the ships were constructed by Blohm+Voss in Hamburg, with final assembly and fitting-out completed in Durban. Acquired under Project Sitron as part of the Strategic Defence Package, the programme restored a blue-water surface combat capability that had effectively lapsed following the retirement of the President-class frigates. Although the Spanish Bazán 59B design initially ranked highest during the evaluation process, it was considered larger and more expensive than required, and the Navy selected the smaller MEKO design to preserve funding for Project Wills, the submarine acquisition programme.
With a standard displacement of approximately 3,590 tonnes and a full-load displacement of approximately 3,700 tonnes, the Valour class is the largest and most capable class of surface combatant ever operated by the SA Navy. Designed as highly survivable multi-role warships, the class incorporates extensive stealth features to reduce radar and infrared signatures, while its modular construction simplifies maintenance and future upgrades. The frigates are equipped for anti-surface, anti-air and anti-submarine warfare. The flight deck and hangar can accommodate up to two Super Lynx 300 helicopters or one Oryx medium utility helicopter, while the ships can also operate two rigid-hulled inflatable boats (RHIBs) for boarding and maritime security operations. A proposal to integrate unmanned aerial vehicles (UAVs) for enhanced surveillance and reconnaissance was later sidelined due to budget constraints.
Originally planned as a five-ship programme, the acquisition was reduced to four vessels because of budget constraints. The class is currently undergoing phased refits and capability upgrades under Project Syne, the South African Navy's long-term frigate modernisation programme, intended to extend operational service into the 2030s. Additional proposals, including upgraded Umkhonto missiles, UAV integration, a larger-calibre main gun, and BrahMos supersonic anti-ship missiles, have periodically been considered but remain unfunded. Despite these limitations, the Valour class remains the most capable surface combatant in sub-Saharan Africa and forms the backbone of South Africa's blue-water naval capability.

Patrol and defence
Warrior class
The Warrior-class Multi-Mission Inshore Patrol Vessels (MMIPV) are the newest surface combatants in the SA Navy, introduced to enhance maritime security within the country's Exclusive Economic Zone. Built under Project Biro by Damen Shipyards Cape Town, the vessels feature a modern, modular design optimised for patrol, interdiction, and low-intensity operations in littoral waters. The class was conceived to succeed the ageing Warrior-class missile strike craft while providing a flexible platform capable of performing a wide range of peacetime and contingency operations.
These multi-role vessels support mine countermeasures, search and rescue, submarine torpedo recovery, humanitarian assistance, and anti-pollution operations, while also performing constabulary missions such as intercepting illegal trafficking, combating illegal fishing, and counter-piracy. Their modular design allows for containerised mission modules, enabling rapid adaptation for specialised tasks, including mine warfare, with facilities to carry one 20-foot or four 10-foot containers. Each ship is equipped with a 20 mm Reutech Super Rogue remotely operated cannon, heavy machine guns, advanced Reutech RTS 3200 radar/optronics systems, and Link-ZA compatible communications suites, while rigid-hull inflatable boats (RHIBs) extend their boarding and interdiction capabilities.
Three vessels — SAS Sekhukhune I, SAS King Shaka Zulu, and SAS Adam Kok III — were delivered between 2022 and 2024. Despite this, the Navy's Blue Print Force plan calls for at least 15 inshore and offshore patrol vessels to fully safeguard South Africa's maritime interests. Future expansion may include additional MMIPVs and larger offshore patrol vessels (MMOPVs), alongside a replacement for the ageing replenishment ship SAS Drakensberg. The Warrior-class MMIPVs thus represent a flexible, multi-mission platform central to South Africa's maritime security and the protection of its marine resources and economic zones.

The Warrior-class strike craft were the backbone of the SA Navy's fast attack capability from the late 1970s into the early 21st century. A total of nine vessels were constructed, with three built in Israel and the remaining six completed at Sandock-Austral in Durban. Based on the Israeli Reshef-class (Sa'ar 4) design, the ships were acquired under Project Japonica to provide a compact, fast, and heavily armed platform capable of coastal defence and sea control. Their introduction allowed the Navy to deliver credible strike capability cost-effectively during the South African Border War and the subsequent democratic era.
The Warrior-class vessels were armed with Gabriel 2 anti-ship missiles, a 76 mm OTO Melara naval gun, a pair of 20 mm Oerlikon autocannons, and additional heavy machine guns, giving them significant anti-surface firepower for their size. Their design emphasised high speed, manoeuvrability, and striking power, enabling operations as fast attack missile craft (FAC-M) in coastal waters. They were also capable of supporting special operations, most notably during Operation Kerslig in 1981, when strike craft deployed reconnaissance and demolition teams off the coast of Luanda, Angola, demonstrating the vessels long-range strike and covert operational capabilities.
Although highly capable during their operational peak, the class became increasingly obsolete in the 21st century. Eight of the nine vessels were retired, with six sold for scrap or sunk as target ships and two retained in reserve. Only one remains nominally commissioned while being gradually replaced by the Warrior-class MMIPVs under Project Biro. Despite budget constraints and the gradual phase-out, the Warrior-class strike craft are remembered as some of the most formidable small surface combatants ever operated in sub-Saharan Africa, and their legacy continues in the naming of the new multi-mission patrol vessels.
