SyberJet Aircraft has kept faith with Williams International as the exclusive engine supplier for its next-generation light jet, the SJ36.
Williams International, globally recognised for its FJ44 family of turbofan engines, will collaborate closely with SyberJet’s advanced engineering team to integrate propulsion technologies tailored for high-speed, high-efficiency flight envelopes. This will enable the SJ36 to reach its ambitious performance targets while maintaining SyberJet’s single-pilot capability.
“Williams International is the clear choice for this programme,” says SyberJet CEO Trevor Milton. “The FJ44 is a workhorse and extremely reliable. There is just no other engine like it in my opinion. Together, we’re taking that proven foundation and pushing it further than ever before. The SJ36 will not only set new records for speed and range, but it will also represent a breakthrough in what pilots and passengers can expect from the light jet category. You couldn’t ask for a better partnership than this.”
The FJ44-4A engine is built to deliver performance, fuel efficiency and reliability, generating 3,621 pounds of thrust, a combined total of more than 7,200 pounds for an aircraft. Given the aircraft’s maximum take off weight of 18,500 pounds, this yields 38.9 per cent thrust-to-weight ratio.
The SJ36 programme was announced last month, and is engineered to redefine expectations in light-jet performance, targeting a cruise speed of Mach 0.88, a range of 3,000nm and a service ceiling of 49,000ft. Upon certification, the SJ36 is expected to become the fastest and longest-range light jet in the world, capable of nonstop missions such as New York to Los Angeles and Los Angeles to Hawaii.
First flights are expected to happen in 2027 with certification and deliveries in 2032.
“We’re thrilled that SyberJet Aircraft is creating new horizons for light jets with the SJ36 and are honoured that the FJ44-4A has been selected,” adds Gregg Williams, CEO of Williams International. “The FJ44-4A engine offers unprecedented performance, exceptional durability and reliability, and the industry’s best lifetime maintenance plan, and is a perfect match for the SJ36."
