General Atomics Aeronautical Systems, Inc. (GA-ASI) and Pratt & Whitney Canada successfully tested a new PT6 E-Series turboprop engine on the MQ-9B SkyGuardian during a 44-minute flight last Monday, July 15.

The recent flight demonstrated not only exemplary handling and acceleration but also positioned the MQ-9B for more robust future operations with enhanced power and efficiency.

Witnessed by GA-ASI and Pratt & Whitney representatives, the event celebrated the integration of the PT6 engine—a product of years of collaboration between the two companies, particularly reminiscent of their previous work on the jet-powered MQ-20 Avenger drone.

“We’re excited to see the PT6 engine on our MQ-9B aircraft,” said GA-ASI President David R. Alexander in a released statement. “The first flight marks an important milestone for MQ-9B SkyGuardian and SeaGuardian customers and missions that require additional power.”

MQ-9 B’s variants, SkyGuardian and SeaGuardian, are fundamentally the same platforms, with slight differences in operational roles based on each platform’s payload configuration. This makes SkyGuardian ideal for aerial missions and SeaGuardian essential for maritime operations.

Pratt & Whitney Canada’s New PT6 E-Series Engine

The PT6 E-Series engine is notable for its reliability and versatility.

GA-ASI noted that the new turboprop engine can produce up to a 33 percent increase in power compared to the current engine used in the MQ-9B “with a highly mature dual-channel Full Authority Digital Engine Controller.

This enhancement comes with the promise of low sustainment costs, especially for customers who choose the Pratt & Whitney engine. It is also facilitated by best-in-class Time Between Overhauls and support from over 50 maintenance and overhaul facilities worldwide.
