propulsion. Accordingly, nothing in this instruction supersedes or changes those authorities, and SEA 08 shall be consulted concerning all matters related to Naval Nuclear Propulsion.

b. For equipment temporarily added to or used with a DSS that interfaces and requires a modification of the host submarine, a Temporary Alteration (TEMP ALT) must be submitted for approval per reference (b) for the modification(s) to the host submarine.

c. A TEMPALT (vice TEMPMOD) must be submitted for approval per reference (b) for modificatfon(s) of host submarine DSS. Examples of such systems are Lock-Out Chambers, Lock Out Trunks, host submarine diver's air systems, etc.

5. Background. Deep Submergence Systems, as defined in reference (a), are those systems and components that, when working together, provide the capability for manned underwater operations.

TEMPMODs are components, systems, or subsystems temporarily installed for the purpose of test and evaluation, research and development programs, or in support of short-term mission or exercise requirements. TEMPMODs are not intended to cover equipment required for normal or long-term operation of the DSS.

6. Action

a. Administration. The cognizant NAVSEA Program Office and the Sustaining Activity for the DSS shall maintain a file of DSS TEMPMODs. The file shall contain the information shown in enclosure (I), and all official correspondence regarding each TEMPMOD. Enclosure (I) has columns for a unique tracking number (TEMPMOD Number), title of the TEMPMOD, the DSS asset/platform on which the TEMPMOD is installed, purpose of the TEMPMOD (i.e., Test and Evaluation, Research and Development, etc.), any restrictions or limitations imposed while the TEMPMOD is installed, the date of approval, date of installation, and th~ required removal date.

Installation approvals and durations shall be in accordance with, and not exceed, the guidelines provided in Table 6.a-1. IN NO CASE shall equipment that is required for regular and routine operations of the DSS asset remain installed by TEMPMOD beyond the time period(s) authorized by NAVSEA. All equipment required for regular operations shall be permanently installed via the formal configuration change process established by the Program Office for the DSS asset. If equipment has been temporarily installed for evaluatio11 purposes via a TEMPMOD, an evaluation shall be conducted by the DSS asset's operational command using a form similar to enclosure (2). If a TEMPMOD is determined as suitable to become a permanent part of the configuration of the DSS asset, the appropriate configuration change process shall be initiated to convert the TEMPMOD into a permanent configuration change prior to the expiration of the approved TEMPMOD installation period.

b. Policy

(I) TEMPMODs will not be accomplished on certified DSS assets unless detailed technical design packages have been approved by NA VSEA for the specific DSS Asset or DSS
