Javelin Advanced Jet Trainer (AJT) joins USAF T-X competition

Stavatti enters Javelin into USAF T-X competition

The Stavatti Javelin is a new twin-engine, two-seat, high performance military jet trainer and Very Light Fighter (VLF) aircraft. Derived from the ATG Javelin Mk-30, the Javelin will be a candidate for the USAF T-X trainer requirement, as well as a trainer and VLF that can be sold to allied air forces worldwide.

The Javelin project began in 1998 with the formation of Aviation Technology Group (ATG) in Englewood, Colorado. Intended as a two-seat civil jet sportplane, the original ATG-1 Javelin mockup was unveiled and displayed at the NBAA convention in 2002. With orders for 151 aircraft by 2003, in 2004 ATG announced a partnership with Israel Aircraft Industries (IAI) to develop and produce a family of two seat military jet trainers designated the Javelin Mk-20 and Mk-30. The prototype Javelin had its maiden flight on 30 September 2005. In December 2007 ATG ceased business operations after failing to raise additional development capital, ultimately declaring bankruptcy in 2008.

On 14 November 2016 Stavatti Aerospace Ltd was granted an Exclusive License to re-imagine, develop, prototype, certify, manufacture, sell, and support the Javelin as an Advanced Jet Trainer (AJT) and VLF from the present owner of the Javelin project’s intellectual property and physical assets.

Upon execution of the licensing agreement, Stavatti immediately began redesigning the Mk-30 Javelin configuration to directly address the current USAF T-X RFP requirements as issued on 31 December 2016. The Stavatti Javelin maintains many exterior characteristics of the original Javelin design but benefits from structural improvements to increase maximum load factor to 9-Gs, more powerful engines, greater internal fuel capacity, increased maximum external warload, higher maximum takeoff weight, a cockpit designed for the T-X mission that satisfies JPATs flight crew accommodation cases 1-8, and a maximum level speed of Mach 1.36. The result is a very affordable, next generation supersonic trainer.

Stavatti is now building the Javelin Industry Team and may partner with a larger prime contractor to expand the Javelin program’s ability to provide comprehensive manufacturing, training, and contractor logistical support to satisfy T-X requirements.

Stavatti will be releasing technical information regarding the reimagined Javelin beginning March 1st followed by a formal response to the USAF T-X RFP on March 30th.

Javelin Advanced Jet Trainer (AJT)


The two-seater, twin-engine Javelin is a non-military jet aircraft developed by the Aviation Technology Group (ATG) to conduct a broad range of uses such as charter, air taxi, training, experiment support, organ transportation, etc. Javelin MK-10 aircraft combines glass instrumentation, safety features, and FJ-33 wide-fan sweep technology jet engines into a two-place executive jet. The aircraft first flew on September 30, 2005. In December 2007, the project was put on hold due to funding related issues.

The Advanced Jet Trainer (AJT) is a derivative of Javelin executive jet for military pilot training featuring high reliability and low maintenance costs, which are common trait within Javelin family of aircraft. The performance of this trainer is equal to or superior to all existing trainers in its class. The Javelin AJT differs from existing military trainers because it can not carry weapons load, which also means a lower operating and maintenance costs. The weapons training is replaced by a simulation system.

Two Javelin AJT military training variants are being developed by ATG: the Javelin AJT MK-20 and Javelin AJT MK-30 aircraft, while the Javelin MK-10 remains as a business jet version. The two variants are externally the same aircraft but differ in their gross weight. The Javelin AJT MK-20 loads up to 280 gallons of fuel, while the heavier MK-30 variant has 350 gal of fuel capacity. Structural limits for both aircraft are +6g/-3g.

In October 13, 2004, ATG and IAI of Israel signed a cooperative agreement for the design, development and manufacture of the AJT aircraft. The AJT prototype first flight was expected in October 2004. The agreement covers marketing and establishes two final assembly lines in New Mexico (USA) and Israel. Cockpit and avionics of AJT will be compatible with 4th and 5th generation aircraft including F-15, F-16, Mig-29, Su-30, Rafale and Eurofighter.
