US Navy Refuses New Freedom LCS

 

US Navy refuses new Freedom LCS unless class-wide propulsion defects are corrected.US Navy's USS Detroit (LCS-7) warship.

US Navy New Freedom Refused:

US Navy builds new Freedom by Lockheed Martin Class Literal Combat Aircraft (LCS) refuses to accept unless the company fixes an error in the service found in its combination gear.USS Detroit (LCS-7) And the USS Little Rock (LCS-9) aircraft were found to have an engineering defect in the bearing system. 

Strengthens the main drive shaft to achieve speed.Bearings wear faster than expected and as a result the combination gears fail.A possible fix would replace two high-speed clutch bearings with different bearing versions that would not fail easily.The Navy will have to operate on 35 planets or less until the problem is resolved.

Little Rock L Gear Failed:

We launched Little Rock L. in March last year.Combined gear failure on CS9.The gear failure ended with a high-speed clutch, a senior Navy official said.The service has informed Lockheed Martin that it will not accept the provision of additional Freedom Class Hole until the design has been fixed.

This could delay the launch of the Navy's Minneapolis-St.Paul (LCS 21) in May.The Navy and Lockheed Martin team, along with the original equipment manufacturer, RENK AG, analyzed a key reason and Determined.There is a class design flaw with high speed clutch bearing.A design fix has been developed and is being developed, followed by factory and sea-based testing.

Naval Sea Systems Command 

The Navy is planning to fix this on ships in the Navy.Naval Sea Systems Command told USNI News in a statement on Tuesday.The cost of resolving the issue in class is yet to be determined.Initial repairs on the Detroit or Little Rock show that the ship can be repaired without being put in a dry dock.

Instead, the repair yard could build a cofferdam around parts of Hill that need to be cut and then accessed through piping and wiring to get to the gear.A source familiar with the company's ongoing procedures said.The company is also testing a method that the company has developed internally that allows the ship to be repaired without having to be traced and save months in the process.

Has developed a solution that really allows you to jack this gear,so you can rotate it in place.By doing so, you reduce the need to dry the dock, and you also reduce the need to remove some of the interference there.

Saudi Frigates:

Saudi Frigates also get LCS-based fixes to a great extent.The ground-based test will be performed on four combination gears developed by RENK based on the LCS design of four frigates for the Royal Saudi Navy.

Sources say the equipment will be in gear, and the issue will not delay the construction of four Saudi ships.Previous defects found on the LCS.A software glitch that caused the US to crash.

The Milwaukee (LCS5) propulsion plant was damaged.Another LCS, USS Fort Worth (LCS-3), had an operator malfunction that caused a variety of damage.
