Viper Aircraft ViperJet Mk II for Sale — The Kit-Built Jet Fighter Experience
The Viper Aircraft Corporation ViperJet Mk II occupies one of the most unusual and exciting niches in experimental aviation — a single-seat, fighter-inspired jet aircraft built from a kit that delivers performance characteristics approaching those of military trainers at a fraction of their acquisition cost. Powered by a Williams International FJ33 turbofan, the ViperJet Mk II reaches speeds exceeding 400 knots and altitudes above 30,000 feet in an aircraft whose exterior profile deliberately evokes the F-16 Fighting Falcon — the most iconic single-engine jet fighter of the modern era. For pilots who have dreamed of experiencing fighter-like performance in a civilian aircraft they own and fly themselves, the ViperJet represents the closest available approximation.
Experimental Category and Builder Requirements
The ViperJet Mk II is certificated in the FAA Experimental — Amateur Built category, which requires the builder to complete the majority of construction personally. Completed and flying examples available on the pre-owned market represent significant investments of builder time and skill, and each aircraft reflects the individual builder's capabilities and choices in equipment and finish. When evaluating a pre-owned ViperJet, review the builder log carefully, verify that the FAA amateur-built majority rule was met, and inspect the construction quality thoroughly — ideally with an A&P mechanic experienced with experimental jet aircraft.
Who Flies the ViperJet?
ViperJet owners and operators are typically experienced pilots — often with turbine backgrounds from military or commercial aviation — who want the experience of single-seat jet flight in an aircraft they can own, operate, and maintain in the experimental category. The aircraft's performance demands respect and type-specific training, and its single-seat configuration means there is no provision for a co-pilot or instructor during flight. Prospective buyers should plan for comprehensive transition training before solo operations.
