Rocket Lab USA (NASDAQ: RKLB) shares jumped nearly 5% in premarket trading Monday after the company landed its largest U.S. government rocket launch contract to date.

The United States Space Force selected Rocket Lab to support space-based missile defense missions through a newly signed launch services contract valued at $266 million.

Under the terms of the agreement, Rocket Lab will be responsible for executing 12 suborbital launches along with an additional six launches on behalf of the Space Force.

The contract also confirms the establishment of the company’s fourth launchpad, to be located at the Pacific Spaceport Complex in Kodiak, Alaska.

Launches tied to this contract are scheduled to begin from the new Kodiak facility starting next year, expanding the company’s operational footprint considerably.

The agreement signals a meaningful step in Rocket Lab’s strategy to diversify its revenue base beyond commercial launch services into the government defense sector.

It also reflects broader demand across the defense industry, coming amid rising geopolitical tensions between the United States and Iran that have sharpened national security priorities.

CEO Peter Beck framed the contract as a vote of confidence from one of the most demanding customers in the aerospace sector, pointing to the scale and urgency of the mission.

“The size and scale of this contract reflects the Space Force’s confidence in our ability to meet their urgent national security demands with speed, responsiveness, and scale, and we’re proud to provide the high-frequency launch capacity required to keep the U.S. ahead of global threats,” Beck said.

Unlike commercial launches, which typically serve private satellite operators and corporate clients, government defense contracts of this nature carry strict national security requirements and demand rapid, reliable deployment capabilities.

Retail sentiment on Stocktwits remained in bullish territory for RKLB over the 24 hours following the announcement, reflecting enthusiasm from individual investors tracking the stock.

Despite the premarket surge, RKLB shares remained down more than 8% on a year-to-date basis heading into Monday’s session, though the stock has gained 33% over the past 12 months.

The Kodiak launchpad addition positions Rocket Lab to handle a higher frequency of government missions while keeping commercial operations running in parallel from its existing sites.

Analysts and investors will be watching closely to see whether this landmark contract serves as a catalyst for additional defense partnerships as U.S. space-based security infrastructure continues to expand.
