Between 1983 and 1987, the Centurions had a midlife renovation and modification (REMO) done, which included among other things night vision equipment, targeting systems, laser range finders, improved gun stabilisation, thermal sleeves on the barrel and exhaust pipes and reactive armour developed by the Swedish FFV Ordnance. Around 80 strv 102 were upgraded with Continental diesel engines and Allison gearboxes in the early 1980s, becoming strv 104.
The Swedish Army gradually phased out its Centurions and Strv 103 during the 1990s as a consequence of comparative tests of the T-72, Leclerc, M1A1 and Leopard 2. They were replaced with the
Stridsvagn 121 and
Stridsvagn 122.
