Abstract: Steering gear mechanical efficiency was measured in drydock for USS KNOX (DE 1052) and found to be 72%. The associated gage readings were later used in sea trials, with inconclusive results. Efficiency of 70% for electro-hydraulic Rapson slide steering gear is now recommended, rather than the traditional values of 80% or 85%.
