Frigates designed in the 1960s and 1970s, such as the US Navy's {{sclass|Knox|frigate|1}}, West Germany's {{sclass|Bremen|frigate|1}}, and Royal Navy's [[Type 22 frigate]] were equipped with a small number of short-ranged surface-to-air missiles ([[AIM-7 Sparrow#Sea Sparrow|Sea Sparrow]] or [[Sea Wolf (missile)|Sea Wolf]]) for point defense only.

By contrast newer frigates starting with the {{sclass|Oliver Hazard Perry|frigate|1}} are specialised for "zone-defense" [[anti-aircraft warfare|air defence]], because of the major developments in [[fighter jet]]s and [[ballistic missile]]s. Recent examples include the {{sclass|De Zeven Provinciën|frigate|0}} air defence and command frigate of the [[Royal Netherlands Navy]]. These ships are armed with [[RIM-66 Standard|VL Standard Missile 2 Block IIIA]], one or two [[Goalkeeper CIWS]] systems, ({{HNLMS|Evertsen|F805|6}} has two Goalkeepers, the rest of the ships have the capacity for another one.) [[RIM-162 ESSM|VL Evolved Sea Sparrow Missile]]s, a special [[SMART-L]] radar and a Thales [[Active Phased Array Radar]] (APAR), all of which are for air defence. Another example is the {{sclass|Iver Huitfeldt|frigate|4}} of the [[Royal Danish Navy]].<ref>{{cite web|url=https://marineschepen.nl/schepen/zeprov.html#specs|title=De Zeven Provinciën classe (LCF)|publisher=Jaime Karreman|access-date=24 September 2018|archive-url=https://web.archive.org/web/20180924185534/https://marineschepen.nl/schepen/zeprov.html#specs|archive-date=24 September 2018|url-status=live}}</ref>
