| The design used in the MTTC testing will require some additional re-design and testing. The composite portion will be replaced by stainless steel and several lengths will be converted to rigid chuting to facilitate flow and ease of installation. New test parts should be available in approximately 12 months. The Navy is funding this work as a follow-on to the MTTC-sponsored design and test. |

Problem:
| The chuting of the CIWS Gun Ammunition Handling System (GHAS) is a continuing problem, accounting for 28% of all requisitioned parts in the past year. The failures are caused by a variety of factors including corrosion, stress and improper maintenance. |
Solution:
| The same GHAS is used in military aircraft. The system used in the F/A-18 fighter has recently been redesigned to address some of the issues. Additional modifications are required to adapt the system to the shipboard system. |
Fleet Impact:
| The Phalanx CIWS continues to be the single Combat System in the Top-Management Interest database. A 25% reduction in maintenance and parts useage will provide a significant improvement in overall system reliability and maintainability. |
Applications:
| This remedy will apply to over 250 Phalanx systems onboard nearly every surface ship in the Navy. |
