Algérie's performance came from welded construction, improved turbines, and reliable high-pressure superheated steam working together. Operating at the stated pressure and temperature allowed compact machinery to produce consistent power without sacrificing economical endurance. With 3,190 tons of fuel, the resulting plant could drive 4,000 nautical miles at 27 knots or roughly twice that distance at 15 knots. The comparison shows why steam conditions and thermodynamic efficiency matter to naval logistics as much as the more visible questions of speed and armour.

Superheated steam unlocked speed and range
High-pressure superheated steam made Algérie's compact machinery efficient enough for both high speed and an 8,000-nautical-mile economical range.
