The German Army Aviation Corps received 110 type CH-53Gs. Except for the first two, all machines were built in Germany. The first flight made by a German CH-53G was made in 1971, followed in March 1973 by the delivery of the first machines to Army Aviation Corps Regiment 35 in Mendig, and shortly afterwards to the newly formed Army Aviation Corps Regiment 15 based at Rheine, and Army Aviation Corps Regiment 25 based at Laupheim.

In order to meet ever more demanding specifications, over time the CH-53G received modifications designed to improve its service life and operational capabilities. These involved three major upgrades: new missile warning and self-protection systems; provision for two external fuel tanks allowing range to be increased to 1800 km when carrying 36 armed soldiers or a 5500-kg payload; and addition of a night vision goggles-compatible cockpit for night low-level flying capabilities. All CH-53Gs were upgraded by Eurocopter Germany by early 2001.
