In March of 1966, the Royal Thai AF became an F-5 operator, and over the years introduced 81 airframes of various versions. The airframe shown here was one of six F-5F delivered to Thailand under US FY # 79-1693. It was among twelve F-5E and three F-5F upgraded to F-5T / F-5TF standard by ELBIT under a contract awarded in 2003. A 2nd modernization program by ELBIT started in 2014, bringing eleven single seat F-5T and three dual seat F-5TF to F-5TH and F-5THF "Super Tigris" respectively. As such, 91693 took part in the LIMA'23 show on the island of Langkawi, Malaysia.

Newly rebuilt from USAF F-5F 79-1693, and dismantled at Sacramento ALC, ready for shipment to Thailand.
