The aircraft continued to fly as trainers, combat and tactical simulation training, electronic countermeasures and warfare training, and test platforms right into the 1980s. They were also used as "hack" aircraft, which are aircraft that perform duties they were not intended for.
For example, many foreign countries used T-33s as cargo planes, liaison aircraft, and as ferries to chauffeur dignitaries around. In the US, they became drone towing planes, and eventually, drones themselves, such as the QT-33A.
Skyfox
By the 1980s, a more modern training aircraft was needed. Shooting Star designer Irvin Culver and a number of other former Lockheed employees formed Flight Concepts Incorporated in 1982, with the intent of modernizing the aging design into a modern twin-engine aircraft. The company's name was later changed to Skyfox Corporation.
Besides its primary role as a trainer, the aircraft was envisioned to have other roles as well, including ground attack. The highly modified aircraft was expected to cost about half of a new comparable trainer, such as the British Aerospace BAE Hawk and the Dassault-Breguet/Dornier Alpha Jet.
With the design work done, Skyfox purchased 80 surplus T-33s. The first one converted was an ex-Canadian Forces CT-133 Silver Star (the Canadian license-built equivalent of the T-33).
After conversion to the Skyfox configuration, the first flight was performed on August 23, 1983 by renowned race pilot Skip Holm at the Mojave Airport. Skyfox Corp was not able to find any buyers for the aircraft, despite its price and capability.
In 1986, Boeing saw potential, and purchased the marketing and production rights. Boeing marketed the Skyfox as a complete converted aircraft built by Boeing, or as a conversion kit, with the customer providing the airframe.
The conversion incorporated about 70% of the existing T-33 airframe, but replaced the existing internal single Allison J33 turbojet engine with two Garrett TFE731-3A turbofan engines mounted externally. Together, the two TFE731s weighed 17% less than the single original engine, provided 60% more thrust on 45% less fuel.
Changing engines provided a large internal volume for fuel storage, eliminating the need for the wing tip tanks (although the wing tip mountings were retained to provide for optional auxiliary fuel tanks if desired). The Skyfox used an aerodynamically improved nose and tail, although the original wings were retained.
Though Portugal signed a letter of intent for 20 conversion kits, no other nation signed on. Faced with a lack of customers, Boeing cancelled the project.
The prototype aircraft (21160, N221SF) remains the only Skyfox built. See public domain photo below. To our knowledge, the aircraft is still airworthy.

Longevity
The T-33 has served with over 30 nations, and continues to operate as a trainer in smaller air forces. Canadair built 656 T-33s on license for service in the Canadian Forces as the CT-133 Silver Star while Kawasaki manufactured 210 in Japan. Other operators included Brazil, Turkey and Thailand.
Many T-33s (and CT-133s) still fly in the US as warbirds at air shows such as the CT-133 Silver Star Mk. III (T-33-129, NX84TB) shown below.

Our favorite Shooting Star is this absolutely beautiful T-33A (58-665, NX556RH) in Thunderbird markings. It is owned by Fowler 'Big Dog' Cary and flown by Jerry ‘Jive’ Kerby.

Jerry's commentator (and now his wife) is the lovely LM ‘Lunar’ Sawyer. I promised Lunar I would not say what the LM stands for. If you have a chance to see this awesome aircraft, please do so.
