===Batch 1, Ikara conversion===
[[File:HMS Naiad F39 1982.jpeg|thumb|right|''Naiad'', an Ikara conversion in 1982]]
Eight of the first ten ''Leander''s were given the so-called "Batch 1" or "[[Ikara (missile)|Ikara]]" conversion,<ref name=RNFp87/> which saw the Ikara anti-submarine warfare missile installed in place of the 4.5-inch gun, plus an additional Seacat system,<ref name=Hansard06Jul81c47W/> and the removal of the [[Type 965 radar]] and its AKE(1) aerial.  The internal space previously used by the Type 965 was used for the [[Action Data Automated Weapons System|ADAWS]] needed for Ikara.<ref name=RNFp87/>
