The LCS saga continues. The USS Freedom suffered another serious failure. There are currently three Freedom Class Littoral Combat Ships (LCS) in service — USS Freedom, USS Fort Worth, and the USS Milwaukee. In the past twelve months, all three of the ships in service have suffered major engine or propulsion gear failures, an unenviable record.
The Navy announced yesterday that the USS Freedom suffered damage to one of its two diesel engines, which will require either a major overhaul or replacement of the engine. The Freedom Class LCS are powered by two Colt-Pielstick diesel engines and two Rolls-Royce MT30 36 MW gas turbines driving four waterjets. The damage to the USS Freedom was reportedly caused by a leak in a pump seal which allowed seawater to leak into the lube oil system. How long the repairs will take and how long the ship will be out of service are unknown.
