As part of its contract for providing the Defense Department with a testbed for hypersonic testing, Rocket Lab on June 17, 2023 successfully completed the first suborbital test launch of its Electron rocket.

The HASTE suborbital launch vehicle is derived from the Company’s Electron rocket but has a modified Kick Stage for hypersonic payload deployment, a larger payload capacity of up to 700 kg / 1,540 lbs, and options for tailored fairings to accommodate larger payloads, including air-breathing, ballistic re-entry, boost-glide, and space-based applications payloads. By leveraging the heritage of Rocket Lab’s low-cost Electron – the world’s most frequently launched commercial small launch vehicle – HASTE offers true commercial testing capability at a fraction of the cost of current full-scale tests.

Because of its military nature, Rocket Lab’s press release was generally terse in providing details. Sources in the industry tell me that this launch was designed to prove out the required suborbital capabilities of Electron prior to the first hypersonic test flight. When that flight takes place, it will carry a hypersonic test vehicle built by another company, Hypersonix.

Rocket Lab with this launch demonstrated again the smart flexibility of the company. It only announced this suborbital concept for Electron in April. Only two months later it has test flown it. It is now ready to fly an actual hypersonic test flight, and waits only for the test vehicle to be provided by Hypersonix. The speed of this program leap-frogged Stratolaunch, which is also offering its Roc airplane and Talon hypersonic test vehicle to the military but started its project in late 2020 and is still not ready for flight.
