What specific area of engineering expertise is still present and engaged internationally, crucial for tackling challenges like precision landing systems?

Designing advanced turbopumps, flight control systems, and cryogenic tankage

Despite the perception of a timeline gap in hardware recovery, the underlying pool of Russian engineering talent remains highly capable and globally engaged. This expertise is essential for the core challenges of developing a modern reusable vehicle. The text specifies that this talent is capable of designing complex components such as advanced turbopumps (critical for high-performance engines), sophisticated flight control systems (essential for GNC during landing), and precise cryogenic tankage (necessary for handling methane and LOX). Having this expertise available, whether domestically or through international exposure, is fundamental for successfully integrating the software and hardware required for autonomous precision landing.
