The Javelin by Stavatti Aerospace of Minnesota is another contender in the United States Air Force's T-X competition attempting to find a replacement for the service's 55+ year old Northrop T-38 'Talon' advanced jet trainers. The contract has the potential to cover some 350 to 400 total aircraft which - coupled with long term support of the product to span decades - stands to make the winner a nice profit. Other contenders in the program include Boeing with Saab of Sweden, Leonardo of Italy, Lockheed Martin with KAI of South Korea, Northrop Grumman with BAe Systems, Sierra Nevada with TAI of Turkey and Textron AirLand.

The Javelin is based on a two-seat civilian market sport aircraft originally developed by Aviation Technology Group (ATG) in the late 1990s. A military version was commissioned at some point by IAI (Israel Aircraft Industries) and this became the Javelin 'Mk-30'. However, despite some work on a prototype being completed, as well as an order for 151 of the type, the project came to naught and ATG was no more before the end of the 2000s.

The Javelin design has since been picked up by Stavatti Aerospace and has been announced as a contender in the USAF T-X program. It retains a two-seat (tandem) crew configuration and carries two engines of (as of right now) unknown make, model and thrust output. The engines are aspirated by small, half-moon intakes located along the sides of the fuselage. Twin vertical tail fins are seated at the rear of the aircraft, positioned over the dual exhaust ports. The wing mainplanes are small in total area and fitted low along the fuselage sides. Horizontal planes are also positioned at the tail in the traditional fashion. Beyond obvious physical design features, internally, the Javelin is reinforced for the rigors of 9G flying. The aircraft can reach speeds of over 1,000 miles per hour (or about Mach 1.36).

At this time (April 2017), Stravatti is attempting to secure a bigger defense player to help push its Javelin product for T-X.©MilitaryFactory.com
