Goldman Sachs has released an in-depth research report on the space sector, focusing on the U.S. Department of Defense’s Space Development Agency (SDA) and its Proliferated Warfighter Space Architecture (PWSA) program. The report highlights the recent awarding of the PWSA Tranche 2 Tracking Layer satellite contracts, valued at $3.5 billion, covering the construction and launch of 72 satellites set for deployment starting in 2029.

The contracts were awarded to four companies: L3Harris Technologies, Inc. (LHX.US), Lockheed Martin (LMT.US), Northrop Grumman (NOC.US), and Rocket Lab USA, Inc. (RKLB.US). Each secured hundreds of millions in orders, with Rocket Lab achieving its largest government contract to date, signaling the rise of innovative disruptors in critical national security projects.

The PWSA program aims to establish a low Earth orbit (LEO) constellation of military satellites to provide end-to-end missile warning, tracking, and defense capabilities. The phased approach ensures continuous upgrades to address evolving space security challenges. Since its inception, the SDA has awarded $13.6 billion in contracts for 518 tracking and transport satellites.

Goldman Sachs analyzed the contract distribution and technological advancements, noting Tranche 2’s improved missile tracking sensitivity, accuracy, targeting capabilities, and advanced tactical data links. The SDA’s satellite deployment plan includes Tranche 0 (28 satellites), Tranche 1 (154), Tranche 2 (264), and the ongoing Tranche 3 (72).

For participating companies, these contracts align with growing U.S. defense budgets, offering mid-term growth potential. Goldman Sachs provided the following assessments: - **L3Harris**: Buy rating, $351 target (based on 4.75% 2026 FCF yield). Risks include defense spending shifts and execution uncertainties. - **Northrop Grumman**: Neutral, $533 target (0.99x 2026 P/E vs. S&P 500). Risks involve geopolitical factors and capital allocation. - **Rocket Lab**: Neutral, $47 target (23.0x 2027 EV/sales, discounted at 10%). Risks include product expansion challenges and capital pressures. - **Lockheed Martin**: Sell, $430 target (0.81x 2026 P/E vs. S&P 500). Risks include geopolitical and spending priorities.

The report also emphasized PWSA’s broader impact on satellite communications and navigation, enabling low-latency global connectivity for applications like telemedicine and autonomous vehicles. However, challenges such as high launch costs and space debris remain critical hurdles requiring innovation and investment.
