In the late 1960s the RSwN aircraft carriers became very costly especialy as their airgroup of SeaVixens where becoming old and needed replacement and the Viggen programe was delayed and very costly there it was decided to gice the SeaVixens a mid life upgrade and then withdraw them in the mid 80s and then let LHDs replace the carriers as fleet flagships.
The result was the LHDA (Landing, Helicopter Dock Assult ships) of the Kung Carl class. They carried 10 Type 200 laningcrafts and room for up to 8 helicopters in a large hangar. most often 2 Seaknights and 4 Cobras where carried.She could accomodate up to 400 troops. The most odd feature where her battey of 6 152mm L55 automatic mouts which could support the troops up to 35km inshore.
The ships entered service in 1978 and 1982, but the analysis of the Falklands war saved the fleet carriers and changed the LHDA role from fleet flagship to mainly amphibius assult ships and traningships for cadets. Some times theyh served as helicopter carriers in GUIK ASW groups.
