OVERVIEW
Temco TT-1 Pinto
The T-610 Super Pinto originated in 1968 as a modified version of the Navy’s Temco TT-1 Pinto two-seat jet trainer. This conversion replaced the original Continental J69 (Turbomeca Marbore) engine with a more powerful General Electric CJ610 (a civilian version of the military J85) and extended the fuselage by 2 meters. The redesign resulted in an aircraft that performed exceptionally well, boasting three times the power of the original model while adding only 20 pounds to its weight.
In the early 1970s, AJI proposed the Super Pinto as a light-strike/counter-insurgency (COIN) aircraft. Powered by a CJ610-4 turbojet engine and fitted with six underwing hardpoints for external armaments, the aircraft, however, failed to secure contracts from the USAF or Turkey.

Subsequently, AJI decided to sell the project. In 1976, the Philippine government acquired the Super Pinto program for $1.25 million through the Philippine Air Force’s Self-Reliance Development Wing. The deal included work drawings, patents, design details, flight test data, manufacturing process sheets, a US-built prototype (which became the first Philippine T-610, later renamed the “Calí” or “eagle”), and an additional fuselage. The agreement also granted the Philippines exclusive global rights to market both military and commercial variants of the aircraft.
However, the program was mired by problems especially after the first prototype was lost in an accident in its evaluation flight (which caused the abandonment of the program when it killed a high ranking PAF officer). This was compounded with the fact that economic mismanagement of the then dictator Ferdinand Marcos Sr. almost lead to a near financial collapse. In the mid-1980s, there were plans to revive the project to replace a bunch of PAF assets from the F-86 Sabres, Lockheed T-33s, and a bunch more. The engine commonality with the PAF’s own Northrop F-5A/Bs were found to be especially promising but this never really took off.
To this day, Manila still technically hold the licensing rights of the Super Pinto but this has been challenged way back in 1988 when Avstar Inc., in cooperation with Shenyang Aircraft Corp. planned to revive the Super Pinto with Avstar T-100 Super Mustang but this time powered by a GE J85 Turbojet or Williams FJ44 with the argument that Manila invalidated its own licensing rights for not having produced any new aircraft for the past decade. This however did also not pan out and the Super Mustang never was produced.

Fairly fast and agile, its very similar in capability with the BAE Strikemaster and should fulfill the same role and niche. If this gets added to Japan as part of a larger ASEAN subtree, this would be an excellent sidegrade to the Thai OA-37B Dragonfly and be a fantastic premium option.
Since the license was sold to the Philippines, this variant is effectively entirely Filipino if it was ever produced (aside from the prototype).
There are actually a few Super Pintos that still remain in the US before it was bought by the Philippine Government (especially as only one out of the total 15 Super Pintos built was sent to the Philippines) so we do have some more pictures of it in US Navy livery (the US Navy used the previous TT-1 Pinto in small numbers as trainers).
