There exists a long-standing, intriguing, discrepancy between the BNL E821 measurement and the Standard Model (SM) prediction for the muon anomalous magnetic moment, $a_{\mu} \equiv (g-2)/2$, at the level of about three standard deviations ($3\sigma$). To test this discrepancy, a new muon $(g-2)$ experiment E989 at Fermilab will improve the experimental uncertainty by a factor of four. Providing that the central value remains unchanged, the new measurement would result into more than $5\sigma$ discovery-level'' deviation from the SM. The experiment at Fermilab will employ the original BNL storage ring with an intense new muon source and state-of-the-art detector systems. I will review the current status of the design of new components and upgrades that are required to achieve the challenging precision goal of the experiment.
