Other defense equipment stocks, such as Curtiss-Wright (CW - Free Report) and Astronics (ATRO - Free Report) , have also outpaced the industry in the past three months. Shares of CW have gained 22.8%, while shares of ATRO have rallied 47.2%.
With RKLB’s recent strong market performance, some investors may feel encouraged to invest quickly. However, it is important to carefully examine the factors behind this growth before making a decision. The key consideration is whether the company can maintain this momentum or if potential risks may affect its future growth. A closer evaluation can help investors form a more balanced and informed view.
Tailwinds for RKLB
RKLB’s recent momentum is supported by steady launch activity and expanding government contracts, which continue to strengthen investor confidence.
In March 2026, Rocket Lab completed its 83rd launch with the Electron rocket through the mission “Insight At Speed Is A Friend Indeed”, deploying a commercial satellite for a confidential customer. The launch took place less than a week after another mission that supported a hypersonic test flight for the Department of War’s Defense Innovation Unit using the HASTE vehicle. This rapid turnaround highlights Rocket Lab’s strong operational capabilities and reinforces its position as a leading provider of small satellite launch services.
In February 2026, Rocket Lab also secured a dedicated mission named Cassowary Vex for the Defense Innovation Unit. The mission will launch on the HASTE rocket from the Mid Atlantic Regional Spaceport in Virginia. This contract further reflects Rocket Lab’s growing involvement in national security space programs and rising demand for its responsive launch services.
Risks to Consider Before Choosing RKLB
Rocket Lab has strong near-term growth potential, but investors should also keep certain risks in mind. One key concern is the company’s rising operating costs, which increased 42.5% in 2025 compared with 2024.
The company continues to invest heavily in developing advanced technologies such as the Neutron rocket, satellite platforms and other space systems. While these investments are important for long-term growth, expenses have been growing faster than revenues, leading to continued losses in recent quarters and possibly in the near term as well.
