The U.S. Air Force recently completed two modifications for its T-38C twin-engine trainer aircraft, the branch announced.

The modifications included the installation of speed break indicators and video data transfer systems. Under the program, 446 trainer jets from the Air Force were upgraded in addition to 10 trainers operated by the U.S. Navy.

Air Force officials say the $50 million operation extends the service life for the jets while also providing updated tools for pilots.

"Service life extension programs and modifications are essential for aging aircraft like the T-38 in order to meet current and future mission needs," program manager Angela Michael said in a press release. "These modifications will ensure continued suitable, safe and effective operation of the T-38 fleet."

As a result of the modifications, pilots operating the Talons have access to a visual indicator of the speed break on the heads-up display. New video data transfer systems were installed to record flight and cockpit data for debriefing students.

The Northrop T-38C Talon is a twin-engine supersonic jet trainer operated primarily by the U.S. Air Education and Training Command to prepare Air Force pilots for combat and bombing missions. The aircraft entered service with the Air Force in 1961.

U.S. defense leaders plan to keep the plane in service until at least 2034, when it is slated to be replaced by the next-generation T-X trainer.
