AT-6 Wolverine

The light-attack plane that kept coming second — the AT-6 Wolverine is Textron's armed turboprop built on the T-6 Texan II trainer, and on paper it should have won: it is faster than the A-29 Super Tucano, has ejection seats the OA-1K lacks, and rides on the logistics tail of thousands of T-6 trainers already in US and allied service. Yet it lost the Afghan light-attack competition to the A-29, produced no US buy from the OA-X experiment, and lost Armed Overwatch to the OA-1K. About ten have ever been built — two American test aircraft headed for divestment, and eight for Thailand, its only real customer. It is the strong contender that never converted.

Overview

The AT-6 Wolverine (production variant AT-6E) is a light-attack and armed-reconnaissance turboprop from Textron Aviation Defense (Beechcraft), derived from the T-6 Texan II trainer — itself a development of the Pilatus PC-9, and cousin to the PC-21. Its selling point was always commonality: with thousands of T-6 trainers flying in US, allied and partner air forces, the AT-6 promised a shared logistics, parts and training pipeline no rival could match — plus real advantages over its competitors, a higher top speed (~510 km/h) and Martin-Baker ejection seats (which the OA-1K does not have). Its avionics were its pitch: an A-10C mission computer, F-16-style controls, a helmet-mounted cueing system, Link-16, a WESCAM MX-15D sensor turret, and six hardpoints for Hellfire, APKWS rockets and guided bombs. And yet the AT-6's history is a chronicle of near-misses: it lost the Afghan Light Air Support competition to the A-29, it and the A-29 both emerged from the 2017–2019 OA-X Light Attack Experiment as finalists with no program of record, and it lost SOCOM's Armed Overwatch to the OA-1K Skyraider II in 2022. The US bought just two for experiments (now slated for divestment); the only operational light-attack buyer is Thailand (eight AT-6THs, delivered 2024–2025). With roughly ten built in total, the AT-6 is the light-attack class's strongest also-ran — a capable aircraft whose commonality advantage never converted into orders, now repitched as a counter-drone platform in search of a market.

Development

The AT-6 grew out of the T-6 Texan II trainer, first flying in armed prototype form on 10 September 2009, and was pitched for the USAF's Light Attack/Armed Reconnaissance requirement that died in budget cuts. Its central chapter was the OA-X Light Attack Experiment (2017–2019): the USAF flew four contenders at Holloman in 2017 — the A-29, the AT-6, Textron's Scorpion jet, and the AT-802L Longsword (the OA-1K's ancestor) — and in February 2018 named the AT-6 and A-29 as the two finalists, per FlightGlobal. But the experiment produced no fleet buy: after a fatal A-29 crash paused the combat demo, the USAF stepped back from a program of record in October 2019 and bought only a handful of each for continued experimentation, per War on the Rocks — which is why the common shorthand that "the A-29 won OA-X" is inaccurate; neither won. The US ultimately took two AT-6Es under a $70.2 million contract (March 2020, first delivered December 2020), tested them at Moody AFB on the AERONet partner-nation networking effort, and certified the type in June 2022 — enabling foreign sales, not signaling a USAF buy — before announcing it would divest its tiny A-29 and AT-6 fleets, per Air & Space Forces Magazine. The one export success came from Thailand, which ordered eight AT-6THs for $143 million in November 2021 as international launch customer, taking the first pair in July 2024 and reaching full fleet by 2025. Through 2025–2026, Textron repositioned the AT-6 as a modular counter-UAV and close-air-support platform and floated markets like Peru, but announced no major new orders.
