The C-130As were replaced by twelve C-130Hs in 1978, and the C-130Es by twelve C-130J Super Hercules in 1999. No. 37 Squadron became the RAAF's sole Hercules operator in 2006, when No. 36 Squadron transferred its C-130Hs prior to converting to Boeing C-17 Globemaster III heavy transports. The C-130Hs were retired in November 2012, leaving the C-130J as the only model in Australian service.
