Editing Leander-class frigate (section)

===Batch 3, Seawolf/Exocet conversion===
[[File:HMS Andromeda DN-SC-90-11423.jpg|thumb|right|''Andromeda'', a Seawolf conversion, in 1990]]

The Seawolf conversion gave the broad-beamed ''Leander''s Exocet anti-shipping missiles in place of the 4.5-inch mounting, a [[Sea Wolf (missile)|Seawolf]] missile system in place of Seacat, Sonar 2016, and the ability to operate the Lynx helicopter.<ref name=Hansard06Jul81c47W/>  All the radar systems were removed and replaced by Type 967, 968, 975 and 910 radars.<ref name=MarriottFrigate94>{{citation|page =94|title=Royal Navy Frigates Since 1945|first1=Leo|last1=Marriott|edition=2|publisher=Ian Allan Ltd|year=1990|isbn=0-7110-1915-0}}</ref> Only five of the broad-beamed ''Leander''s were converted to carry Seawolf due to costs (£70 million for each refit) and, as a lesser consideration, to retain some ships capable of [[naval gunfire support]].<ref name=RNFp94/>
