Rolls-Royce WR-21 Marine Gas Turbine from China
The Rolls-Royce WR-21 is an intercooled recuperated gas turbine optimized for high efficiency in naval vessels like destroyers. Classified under HTS 8406.10.90.00 as 'other' turbines for marine propulsion, it uses vapor (gas) expansion distinct from steam turbines. Its design for intermittent high-speed marine use fits this subheading.
