• The four new missions follow on from the success of Rocket Lab’s first HASTE launch for Leidos in June this year

LONG BEACH, Calif. / Sep 12, 2023 / Business Wire / Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a global leader in launch services and space systems, today announced it has signed a contract with Leidos to launch four HASTE (Hypersonic Accelerator Suborbital Test Electron) missions.

The missions, scheduled across 2024 and 2025, will lift off from Rocket Lab Launch Complex 2 at Virginia’s Mid-Atlantic Regional Spaceport within NASA’s Wallops Flight Facility. Rocket Lab was selected by Leidos to provide hypersonic test launch capabilities with HASTE under the MACH-TB project. The project was awarded by Naval Surface Warfare Center (NSWC) Crane through the Strategic and Spectrum Missions Advanced Resilient Trusted Systems (S2MARTS) Other Transaction Authority (OTA) vehicle on behalf of the U.S. Department of Defense Test Resource Management Center (TRMC).

“Our first HASTE mission in June this year successfully demonstrated HASTE’s ability to accelerate the cadence of hypersonic flight testing for the nation. We’re proud to now follow it up with a series of four additional missions for Leidos to support hypersonic technology innovation and technology maturation,” said Brian Rogers, Senior Director – Global Launch Services.

Rocket Lab’s HASTE suborbital launch vehicle is derived from the Company’s Electron rocket but has been modified to support hypersonic payload deployment. 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.

Rocket Lab launched the first HASTE mission on 17 June 2023 for Leidos under the Multi-Service Advanced Capability Hypersonic Test Bed (MACH-TB) program.

HASTE is operated under Rocket Lab National Security (RLNS), the Company’s wholly owned subsidiary created to serve the unique needs of the U.S. defense and intelligence community and its allies.

These forward-looking statements are based on Rocket Lab’s current expectations and beliefs concerning future developments and their potential effects. These forward-looking statements involve a number of risks, uncertainties (many of which are beyond Rocket Lab’s control), or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Many factors could cause actual future events to differ materially from the forward-looking statements in this press release, including risks related to delays and disruptions in expansion efforts; our dependence on a limited number of customers; the harsh and unpredictable environment of space in which our products operate which could adversely affect our launch vehicle and spacecraft; increased congestion from the proliferation of low Earth orbit constellations which could materially increase the risk of potential collision with space debris or another spacecraft and limit or impair our launch flexibility and/or access to our own orbital slots; increased competition in our industry due in part to rapid technological development and decreasing costs; technological change in our industry which we may not be able to keep up with or which may render our services uncompetitive; average selling price trends; failure of our launch vehicles, spacecraft and components to operate as intended either due to our error in design in production or through no fault of our own; launch schedule disruptions; supply chain disruptions, product delays or failures; design and engineering flaws; launch failures; natural disasters and epidemics or pandemics, including COVID-19; changes in governmental regulations including with respect to trade and export restrictions, or in the status of our regulatory approvals or applications; or other events that force us to cancel or reschedule launches, including customer contractual rescheduling and termination rights; risks that acquisitions may not be completed on the anticipated time frame or at all or do not achieve the anticipated benefits and results; and the other risks detailed from time to time in Rocket Lab’s filings with the Securities and Exchange Commission (the “SEC”), including under the heading “Risk Factors” in Rocket Lab’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the SEC on March 7, 2023, and elsewhere (including that the impact of the COVID-19 pandemic may also exacerbate the risks discussed therein). There can be no assurance that the future developments affecting Rocket Lab will be those that we have anticipated.
