Abstract
The SKA South Africa radio astronomy roadmap is in 4 phases: Phase 1: construction of the pathfinder KAT-7 (7 × 12m antennae) completed in December 2010 & in operation since then (8 HI scientific publications — description of the results to follow); Phase 2: construction of the SKA precursor MeerKAT (maximum baseline ∼8 km) (64 × 13.5m antennae), fully funded (RSA), completed in mid-2018; Phase 3: MeerKAT merged with SKA 1 -mid (64 + 136 = 200 antennae — max baseline ∼150 km ∼1/2 FAST collecting area) 2018–2023; Phase 4: SKA2 (∼2500 ?, SF or PAFs ? antennae) (phases 1 & 2) 2023–2030.
