VISR

A reusable multi-mission flyer being developed for defence applications. With the ability to accelerate between Mach 5 to Mach 10, this rapidly deployable, highly- manoeuvrable aircraft is designed for hypersonic ISR and other repeatable operations.

Engineered for high-cadence hypersonic defence missions

Repeated hypersonic flight

Designed for high-cadence flight, this aircraft can be refuelled and ready to fly in a short timeframe, proving capable of multi-mission payload delivery.

Ceramic matrix composites

Manufactured using CMC materials as they are lightweight, have a high strength-to-weight ratio, perform at high temperatures and are shock resistant.

Launch from air and ground

VISR will have the flexibility to be deployed from the ground, or once boosted to atmospheric flight conditions, and then return to land on a conventional runway.

Manoeuvrable trajectory

While capable of fully autonomous flight, VISR has the ability to change direction and evade enemy air defences, offering uncontested mission deployment.

Defence hypersonics

The global defence sector is growing rapidly. Hypersonic capabilities have become a critical priority, heightened by geopolitical risks and accelerated by international partnerships – like AUKUS.

High development costs, supply chain constraints, and the lack of testing capabilities have created a major technical gap in defending against hypersonic threats. However, with the ability to deliver hypersonic ISR and payload delivery, VISR offers an affordable, multi-mission, high-speed asset for counter-hypersonic applications.

Uncontested payload delivery

The VISR aircraft is designed for uncontested payload delivery in contested and denied environments, especially where traditional systems are increasingly constrained. Being engineered for high-speed rapid deployment, this flight platform is suited for key defence applications: hypersonic ISR, time-sensitive logistics resupply, and mission-critical system insertion.

With significant speed, range, and survivability advantages over alternative aircraft, VISR will have the longest flight time of any scramjet flyer and will become a strategically critical defence asset.

Delivering sustained mach 5+ flight

Our most recent DART AE mission marked a critical step in validating flight system performance in true hypersonic conditions. Achieving speeds beyond Mach 5 within a real-world hypersonic environment, the program generated high-value flight data across propulsion, materials, and guidance systems.

In partnership with NASA and Rocket Lab, this milestone marked the world’s first hydrogen-powered scramjet hypersonic flight – demonstrating our capability to develop next-generation, scalable, and commercially viable flight platforms.

Power source

Powered by SPARTAN

VISR is powered by four SPARTAN scramjet engines – Hypersonix’s fifth-generation propulsion system. The flight-proven, hydrogen-powered SPARTAN delivers enhanced mission reliability, designed for high-cadence flight.

Why use H2 as fuel?

Hydrogen is fuel for a low carbon future

Hydrogen can be produced from just water, using renewable energy. Burning it in an engine produces only water vapour. There is a global movement towards low-carbon fuels and Australia is set to become a key player in the hydrogen industry, with government and private investment into local green hydrogen production facilities.
Hypersonix has partnered with BOC Australia, who has announced its intention to build a green hydrogen production facility using seawater as the main ingredient, in Queensland.

The clean hydrogen industry is growing quickly Australia-wide, with over $1.6 billion invested in the private sector and $1.27 billion in the public sector. The price of clean hydrogen is projected to decrease to between $2 and $4 per kilogram by 2030.

Hydrogen is an excellent aerospace fuel

The space industry has historically utilised hydrogen as rocket fuel, including in the space shuttle program.

Hydrogen is non-toxic and its low density means any leaks and fires are directed upwards — unlike hydrocarbon fuels, which could pool under the aircraft. Hypersonix’s vehicles are also unmanned, reducing the risks to humans. Hydrogen has approximately 2.5 times the energy density of hydrocarbon fuels, such as kerosene, making it the perfect fuel in an industry where every gram counts.
