Rocket Lab shares climbed in extended trading Tuesday after the company announced a new $266 million defense award. The gain came after investors reacted to news that the launch company had secured a firm-fixed-price completion contract tied to suborbital launch work for the U.S. military.

According to the announcement, the contract was awarded by the U.S. Space Forces' Space Systems Command. The deal covers a series of 12 suborbital launches, giving Rocket Lab another notable win in the national security and defense segment of the space market.

The after-hours move suggests investors view the contract as a meaningful addition to Rocket Lab’s backlog and government business. Defense-related launch work can be especially important for space companies because it can provide clearer revenue visibility and strengthen long-term relationships with federal customers.

For Rocket Lab, the award also highlights continued demand for its launch capabilities beyond commercial missions. With the company adding another major government contract, the market appeared to respond positively to the potential impact on future growth and defense-sector momentum.
