Core Viewpoint - Goldman Sachs released an in-depth research report focusing on the U.S. Space Development Agency's (SDA) "Proliferated Warfighter Space Architecture" (PWSA) project, particularly analyzing the contract awards for the third batch of tracking layer satellites [1][3]. Summary by Sections Contract Awards and Project Overview - The SDA announced the third batch of tracking layer satellite contracts on December 19, 2025, with a total value of $3.5 billion, covering the construction and launch of 72 satellites, expected to be gradually deployed starting in 2029 [3]. - The PWSA project aims to create a low Earth orbit (LEO) satellite constellation for missile warning, tracking, and defense services, evolving through phased implementation to address complex space security challenges [3][4]. Satellite Development and Funding - Since the project's inception, the SDA has awarded contracts worth $13.6 billion for the construction of 518 tracking and communication satellites, with the third batch showing both quantity growth and significant technological upgrades [4][6]. - The satellite iteration plan is divided into multiple batches: Batch 0 deployed 28 satellites, Batch 1 expanded to 154, Batch 2 increased to 264, and the current Batch 3 includes 72 satellites [5]. Company Analysis and Ratings - For L3Harris, Goldman Sachs gives a buy rating with a 12-month target price of $351, based on a projected 4.75% free cash flow yield for 2026 [10]. - Northrop Grumman receives a neutral rating with a target price of $533, calculated based on a relative P/E ratio of 0.99 times the expected 2026 earnings [10]. - Rocket Lab is also rated neutral with a target price of $47, based on a projected enterprise value/sales ratio of 23.0 times for FY2027 [11]. - Lockheed Martin is rated sell with a target price of $430, determined by a relative P/E ratio of 0.81 times the expected 2026 earnings [12]. Industry Impact and Challenges - The PWSA project is expected to have a profound impact on satellite communication and navigation, enabling low-latency global communication access, which supports emerging applications like telemedicine and autonomous driving [12]. - The aerospace sector faces challenges such as high launch costs, bandwidth and latency issues, and space debris, which are critical constraints on further industry development [12].
