Fermilab carries out an extensive program of accelerator-based high-energy particle physics research, which relies on 8 GeV and 120 GeV proton accelerators. Routine operations with 700 kW, 120 GeV proton beam power on a neutrino target was achieved in 2017. There are plans to further increase the beam power to the 900 kW range. The next major upgrade of the Fermilab accelerator complex, the PIP-II project, is under development. Its goal is to deliver 1.2 MW of beam power on target at the start of the DUNE experiment in the middle of the next decade. PIP-II will replace the existing 40-year old 400 MeV normal-conducting Linac with a modern 800 MeV superconducting RF based linear accelerator. There are several concepts for future upgrades that will increase the beam power to >2.4 MW, after replacement of the existing 8 GeV Booster synchrotron. The Muon Campus provides 3.1 GeV polarized muons to the g-2 experiment and will provide 8 kW of 8 GeV protons to the Mu2e production target. The Fermilab Test Beam Facility provides a primary 120 GeV proton beam of moderate intensity, (1-300 kHz) and secondary particle beams of energies down to about 1 GeV, consisting of hadrons, muons and/or electrons/photons for detectors tests. In this article we discuss the current performance of the Fermilab accelerator complex, the upgrade plans for the next two decades, and the accelerator R&D program to address cost and performance risks for these upgrades.
