TITLE / SUBJECT: TOPSIDE ANTENNA REMOVALS DURING PSNS SHIPCHECKS

REFERENCES:

ENCLOSURES:

1) LIST OF ANTENNA’S

Enclosure 1_CVN 74

Ant List Per April 17 SC.xlsx

QUESTION OR ACTION REQUIRED:

During the month of April 2017, NNS conducted topside shipchecks for the island, mast and tower aboard CVN

74. It was soon realized that many of the radio antennas normally on location were not present. Further observation revealed that the cables were left in place - bagged and tagged in some cases - at the foundation.

Later during the shipchecks, NNS witnessed the removal of the larger, SPQ-9B antenna. NNS consulted the

CVN 74 CSMO who explained that they (SF) were preserving and restoring the antennas and intended on reinstalling them back in place.

1. NNS requests validation that the antennas highlighted on Enclosure (1) that were not present during shipchecks will be reinstalled and that NNS should develop products to remove these antennas.

2. NNS requests validation whether any antenna’s on this list will be removed from the ship prior to execution of the RCOH.
