Sample_Sustainment_Scenario_Task.docx

TASK

IAW Section L para 4.2.3.1.7 The Offeror shall describe their processes, analysis, and rationale that determine their selected corrective action for the sample sustainment scenario. The Offeror shall describe in their solution all actions needed to resolve the situation and what actions they will take that support the Government. The solution shall define the issue, incorporate all appropriate technical documentation and provide full implementation details. The Offeror’s solution shall be complete and take into account the necessary actions to maintain/sustain the weapon system throughout its lifecycle. From the list of documents in the Bidder’s Library, the Offeror shall document in table format all technical documentation that will be affected with incorporation of the proposed solution.

SAMPLE SUSTAINMENT SCENARIO

NOTES

· All information required to answer this sample sustainment scenario is contained within the scenario or in the GSSC Bidder’s Library. The Government will not provide additional information to offeror including requests for information relating to this sample sustainment scenario.

· All assumptions should be clearly stated to ensure the Government team can evaluate the quality, thoroughness, and timeliness of the offeror’s solution and how well it synthesizes the solution activities required to successfully resolve and implement the sample scenario.

· All indications not specifically provided should be considered as achieved, having correct / acceptable indications.

· All supply information provided in this scenario is not necessarily an accurate representation of current status, but should be assumed to be accurate for purposes of answering this sample sustainment scenario.

· T.O. 21M-LGM30F-1-7 is an incorrect reference in T.O. 21M-LGM30G-1-17. An AFTO-22 has been submitted to correct the reference to T.O. 21M-LGM30F-1-24.

On-site team initiated Para 11.2.2 and reported the following to TSM:

1. During para 11.2.4 SELM Quick Look Inspection - G&C umbilical was expected to have been released but is reported to still be connected to the missile.

TSM directed the on-site team to initiate para 11.2.7 and report findings before proceeding.

1. On site team reports SCS is in Safe position (no noted anomalies) and now installed SCS safing pin.

Test LCC is requested to initiate a GMI for Delta 05 and report status.

1. Test LCC reports LF Status Display indication; 12/0015:11 LFDN.

TSM directs on-site team to complete and report finding of para 11.2.5 before proceeding.

TSM directs on-site team to initiate para 11.2.6 and report findings before proceeding.

TSM directs on-site team to initiate para 11.2.4 and report findings before proceeding.

1. Team reports the following IAW para 11.2.4.a. G&C umbilical was expected to have been released but is reported to still be connected to the missile.

2. On-site team is directed to complete step 11.2.4.b and report all SCM TCD summary printout, TCD data printout, TCD detail status printouts: On-site team then reports the following indications:

SYSTEM=A/CDB

TSM request Test LCC to initiate Ground Maintenance Interrogation.

The TSM and ICBM SD System Engineering Level Evaluation & Correction Team (SELECT) engineering make the following observations from TCD Summary, Data, and Detail Status printouts
