The TF-50 Trainer Jet is Lockheed Martin's proposed advanced trainer and light attack fighter version of the KAI T-50 family. Lockheed markets the TF-50 as a production-ready path for faster fourth- and fifth-generation fighter training; the TF-50A was submitted for U.S. Air Force tactical training needs, while the TF-50N was a U.S. Navy trainer proposal before Lockheed withdrew from the 2026 UJTS solicitation.
Open official and defense-industry sources present TF-50 as a proposal built from the proven T-50/FA-50 industrial base, not as a delivered conflict-use aircraft. The separate FA-50PH catalog record covers the Philippine combat aircraft that has documented Marawi and counterinsurgency use.
Lockheed Martin says the active T-50 production line in South Korea supports full value-stream production and could support a Final Assembly and Check-Out facility when needed.
The Red 6 work is centered on augmented-reality synthetic training for TF-50/T-50 ground and airborne training environments.
Sources reviewed through 2026-07-03 describe offers, requests for information, product cards, competition reporting, and simulator integration; they do not document TF-50 procurement, delivery, fielding, or combat use.
Lockheed Martin uses TF-50 for the proposed advanced trainer/light-attack derivative of the T-50/FA-50 family; TF-50A and TF-50N identify customer-program configurations rather than fielded production models.
| Variant | Configuration | Designation notes |
|---|---|---|
| TF-50A | U.S. Air Force tactical trainer proposal | Submitted for an Air Force trainer program covering tactical training, adversary air support, and tactical fighter surrogate missions; Lockheed described the configuration as adding radar, electronic warfare, tactical data link, and other Air Combat Command-oriented capabilities.

| TF-50N | U.S. Navy trainer proposal | Configured for Navy fast-jet training, landing qualification, adversary air, tactical surrogate, and chase missions; Lockheed later told Breaking Defense it would not pursue the 2026 UJTS solicitation.

The TF-50 proposal sits inside the KAI T-50 and FA-50 aircraft family rather than a separate combat lineage.

 | Light combat aircraft variant | Lockheed Martin describes TF-50 and TF-50A as variants of the T-50 family, while KAI identifies the FA-50 as part of the same T-50-derived light-combat-aircraft family represented in the catalog by the FA-50PH record.
