# Beechcraft T-6 Texan II
The Beechcraft T-6 Texan II is a single-engine, two-seat turboprop aircraft used as the primary trainer for U.S. Air Force and U.S. Navy student pilots, built as a military derivative of the Swiss Pilatus PC-9.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/) It is the aircraft component of the Joint Primary Aircraft Training System (JPATS), a program that also includes simulators, ground-based training devices, and a Training Integration Management System.[2](https://www.navair.navy.mil/product/T-6A-Texan-II?page=1) More than 1,000 aircraft have been delivered, and the fleet has logged over 5 million flight hours across 14 nations and two NATO flight schools.[3](https://media.txtav.com/244551-history-making-beechcraft-t-6c-texan-ii-sale-supports-the-u-s-vietnam-comprehensive-strategic-partnership-advances-u-s-interests-in-th/)

## Role and design
The T-6A trains entry-level student pilots in the basic flying skills common to Air Force and Navy pilots before they progress to one of four tracks: the bomber-fighter or Navy strike track, the airlift-tanker or maritime track, the turboprop track, and the helicopter track.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/) The stepped-tandem cockpit places one crewmember behind the other, with student and instructor positions interchangeable, and a pilot can fly the aircraft alone from either seat.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/) • [4](https://www.airandspaceforces.com/weapons/t-6/)
The aircraft is fully aerobatic and carries a pressurized cockpit with an anti-G system, ejection seats, and digital avionics with sunlight-readable liquid crystal displays.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/) Its side-opening, one-piece canopy has demonstrated bird-strike resistance at speeds up to 270 knots.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/) With the PT6A-68 engine, the aircraft can climb at 3,100 feet per minute initially and reach 18,000 feet in under six minutes.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/)
## JPATS acquisition
The 1989 Department of Defense Trainer Aircraft Master Plan identified the aircraft portion of the Joint Primary Aircraft Training System, and the aircraft was formally named T-6A in 1997.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/) The program was designed to replace the Air Force's T-37B and the Navy's T-34C trainers along with their associated ground-based training systems.[6](https://www.everycrsreport.com/reports/R44856.html) In December 1990 the Joint Requirements Oversight Council validated a mission need for nearly 900 [trainer aircraft](https://www.edgepedia.org/trainer-aircraft).[7](https://www.globalsecurity.org-www.globalsecurity.org/military/systems/aircraft/t-6-dev.htm)
Raytheon was awarded the JPATS acquisition and support contract on February 5, 1996, after a "fly-before-buy" competition in which each offeror's aircraft was flown for evaluation.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/) • [8](https://www.gao.gov/products/b-261953.5) The competitive selection of an existing commercial design reduced original program estimates from about $7 billion to about $4 billion at contract award.[9](https://www.govinfo.gov/content/pkg/GAOREPORTS-NSIAD-97-172/pdf/GAOREPORTS-NSIAD-97-172.pdf) Raytheon produced the aircraft in Wichita, Kansas, under a licensing agreement with Pilatus, modifying the PC-9 with improved ejection seats, improved bird-strike protection, a pressurized cockpit, an elevated rear instructor seat, and cockpit dimensions sized to accommodate a wider range of male and female pilot candidates.[9](https://www.govinfo.gov/content/pkg/GAOREPORTS-NSIAD-97-172/pdf/GAOREPORTS-NSIAD-97-172.pdf) The cockpit was required to accommodate at least 80 percent of the eligible female pilot population, and the ejection seat's minimum pilot weight was set at 116 pounds.[10](https://gao.justia.com/department-of-defense/1997/9/defense-acquisition-nsiad-97-172/)
The T-6A entered development flight test in July 1998, received FAA type and production certification on July 30, 1999, and reached a Milestone III full-rate production decision in December 2001.[2](https://www.navair.navy.mil/product/T-6A-Texan-II?page=1) The first operational aircraft arrived at [Randolph Air Force Base](https://www.edgepedia.org/randolph-air-force-base), Texas, in May 2000, and Air Force production was completed in 2010.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/) Joint Primary Pilot Training began in October 2001 at Moody AFB, Georgia, and the aircraft is now flown at Columbus AFB, Mississippi; Vance AFB, Oklahoma; and Laughlin AFB and Sheppard AFB in Texas.[1](https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104548/t-6a-texan-ii/)
## Variants and operators
The T-6B is the Navy's upgraded-avionics variant; in August 2009 the Navy began an avionics upgrade program to outfit T-6A aircraft with significant avionics improvements, and the T-6B replaced the T-34C.[11](https://www.navy.mil/Resources/Fact-Files/Display-FactFiles/Article/2166435/t-6b-texan-ii-turboprop-trainer/) The T-6C is a next-generation version designed for instruction from ab initio through advanced operational training, with an Esterline CMC Cockpit 4000 avionics suite, an integrated dual FMS with GPS/INS navigation, a head-up display with F-16 or F/A-18 display formats, and a hard-point wing for external fuel tanks and weapons training.[12](https://defense.txtav.com/~/media/beechcraft-defense/files/t6c_texan_ii_litho_revise4)
Beyond the U.S. services, the type serves the Hellenic, Argentine, Israeli, Royal Air Force, Iraqi, Royal Canadian, Royal Moroccan, Colombian, Royal New Zealand, Royal Thai, and Tunisian air forces, the [Mexican Navy](https://www.edgepedia.org/mexican-navy) and Air Force, and the Vietnam Air Defense Air Force, which received its first five of twelve T-6C aircraft at Phan Thiet Airbase in November 2024 as the 14th T-6 nation.[3](https://media.txtav.com/244551-history-making-beechcraft-t-6c-texan-ii-sale-supports-the-u-s-vietnam-comprehensive-strategic-partnership-advances-u-s-interests-in-th/) In December 2025 Textron Aviation Defense finalized its first contract to deliver the T-6JP Texan II to the [Japan Air Self-Defense Force](https://www.edgepedia.org/japan-air-self-defense-force), which selected the type to replace the Fuji T-7; the initial contract covers two aircraft with deliveries scheduled for 2029, making Japan the type's 15th foreign customer.[13](https://media.txtav.com/258647-textron-aviation-defense-secures-first-contract-to-deliver-beechcraft-t-6-texan-ii-integrated-training-system-to-japan/)
## Physiological events and the oxygen system
Beginning in 2018 the fleet faced unexplained physiological events linked to its onboard oxygen generation system (OBOGS). A six-month examination by Air Education and Training Command and Air Force Materiel Command, with Navy and NASA participation, identified varying oxygen concentrations in the cockpit as the major factor; the fluctuating levels, though generally in excess of what the body needs, caused physiological stress with hypoxia-like symptoms.[14](https://www.af.mil/News/Article-Display/Article/1634093/af-announces-corrective-measures-for-oxygen-breathing-system-in-training-aircra/) In February 2018 the 19th Air Force commander directed an operational pause across the T-6 fleet, and inspections found the OBOGS filter and drain valves failing at much higher than anticipated rates.[14](https://www.af.mil/News/Article-Display/Article/1634093/af-announces-corrective-measures-for-oxygen-breathing-system-in-training-aircra/) The Air Force initiated a two-to-four-year redesign of the OBOGS to stabilize oxygen levels, adjusted the system's software algorithm with the manufacturer, and added new maintenance procedures such as purging excess moisture from the system.[14](https://www.af.mil/News/Article-Display/Article/1634093/af-announces-corrective-measures-for-oxygen-breathing-system-in-training-aircra/) T-6s completed Next-Generation OBOGS upgrades in 2024, which drastically reduced the hypoxia-type incidents that had plagued the fleet.[4](https://www.airandspaceforces.com/weapons/t-6/)
In 2022 the T-6 fleet and hundreds of other aircraft were grounded after inspections revealed a potential defect in a component of the ejection seat's cartridge actuated devices, the cartridges that explode to start the ejection sequence; the fleet was inspected and some components were replaced.[15](https://apnews.com/article/245af4f7949346feecdd8032a92d031c) On May 13, 2024, an instructor pilot was killed at Sheppard Air Force Base, Texas, when the ejection seat of a T-6A activated during ground operations while the aircraft was taxiing. The accident investigation board found two causes: the instructor failed to fully install the rear cockpit ejection seat safety pin during the after-landing checklist, and he partially disconnected from the seat, allowing a harness chest strap V-ring to catch on and inadvertently actuate the ejection control handle.[16](https://www.afjag.af.mil/LinkClick.aspx?fileticket=JJ90O3U_gf0%3D&portalid=77)
## Modernization and readiness
The Air Force's Avionics Replacement Program (ARP) addresses diminishing manufacturing sources and material shortages in the T-6A's aging avionics. On June 16, 2025, the Air Force Life Cycle Management Center awarded Borsight Inc. of Ogden, Utah, a firm-fixed-price, single-award indefinite-delivery contract with a ceiling of $2.18 billion to replace and install affected components across the fleet of 442 T-6A operational trainer aircraft and to upgrade the associated ground-based training devices.[17](https://aviationweek.com/defense/light-attack-advanced-training/borsight-wins-218b-t-6-avionics-contract) • [18](https://govtribe.com/file/government-file/post-award-synopsis-fa810625db001-dot-pdf) The program will replace the T-6A's aging head-up display cockpit displays and interface, integrate simulated air-to-air and air-to-ground weapons and electronic warfare, and modernize debriefing aids; a crash-survivable flight data recorder is also being installed.[4](https://www.airandspaceforces.com/weapons/t-6/) Contract award had been delayed from November 2023 to July 2024 by source selection issues.[19](https://comptroller.war.gov/Portals/45/Documents/execution/reprogramming/fy2024/prior1415s/24-11_PA_Omnibus_Fina_signed_20240628_Implemented.pdf)
Readiness has been a constraint. The T-6's mission capable rate fell to 54 percent in fiscal 2024, down nearly 10 points from the prior year, affecting pilot production and prompting discussion of shifting some T-6 training to the T-7A when that aircraft enters service.[20](https://www.airandspaceforces.com/air-force-mission-capable-rates-fiscal-2024/) • [4](https://www.airandspaceforces.com/weapons/t-6/) Sustainment of the more than 700-aircraft government fleet continues under a renewed five-year sustaining engineering and program management contract with Textron Aviation Defense, and in July 2026 [Pratt & Whitney Canada](https://www.edgepedia.org/pratt-and-whitney-canada) was awarded a nine-year, $1 billion contract from V2X Inc. to overhaul more than 750 PT6A-68 engines powering the U.S. fleet.[21](https://media.txtav.com/263856-textron-aviation-defense-awarded-five-year-sustaining-engineering-and-program-management-contract-for-beechcraft-t-6-texan-ii-fleet/) • [22](https://www.rtx.com/news/news-center/2026/07/20/rtxs-pratt-whitney-canada-awarded-1-billion-jpats-sustainment-contract) The T-7A program will eventually extend to replacing the T-6 Texan.[23](https://www.aetc.af.mil/News/Article-Display/Article/4346536/t-7a-red-hawk-a-new-era-for-pilot-training-begins-at-randolph/)
