T64

The T64 is a turboshaft engine for applications on medium-size transport helicopters, such as the Sikorsky CH-53. The engine  was built between 1968 and 1975 in cooperation with GE and Klöckner-Humboldt-Deutz (KHD). MTU’s role in this engine was chiefly assembly and acceptance test work at its Munich facility. In all, 247 T64 engines were delivered.

Between 2003 and 2008, the company made technical improvements to the T64 and made it fit for operations in climatically and geographically challenging regions. In 2014, the comprehensive modification program to upgrade the T64-7 to the more powerful -100 standard was completed.

Today, MTU provides repair and maintenance services for the T64.
