Recommendations
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| Department of Defense | To avoid spending funds on construction from a design that may require costly modifications to meet requirements, the Secretary of Defense should require the Secretary of the Navy to conduct survivability modeling to assess the impact that reduced capabilities of various subsystems have on ship survivability when integrated into the overall NSSN design. |
Closed – Not Implemented
Five submarines are currently under construction. Recommendation on design of submarine is now moot.
|
| Department of Defense | The Secretary of Defense should take steps to ensure that the results are used in making fiscal year spending decisions on the program. |
Closed – Not Implemented
Recommendation is tied to implementation of another recommendation.
