Background The Towed Array Handling Equipment Facility TAHEF is the Naval Sea Systems Command (NAVSEA) certified Designated Overhaul Point for the OK-542 Thinline Towed Array Handling Equipment (TLTAHE). The OK-542 TLTAHE is essential for deployment and retrieval operations of the Thinline Towed Array (TLTA) used on SSBN/SSGN 727 CL Submarines. The OK-542 Capstan Drive Unit (CDU) and CDU Hydraulic Motor provide positive control of the array during transfer operations. The OK-542 Stowage Drum Unit (SDU) and SDU Hydraulic Motor work to maintain tension during array transfer operations and provide compact stowage of the TLTA during periods of inactivity. The SDU and CDU Hydraulic Motors are overhauled at the TAHEF. The hydraulic motor parts identified below are components of the OK-542 capstan and stowage drum hydraulic motors and are required for overhaul at the TAHEF.
