The program manager for the Littoral Combat Ship’s sea-frame is under investigation following allegations of “inappropriate personal behavior,” the Navy said Friday.

Capt. Jeff Riedel has been temporarily reassigned pending the outcome of the investigation, said Chris Johnson, a spokesman for Naval Sea Systems Command (NAVSEA). Johnson would not specify the nature of the accusations.

Rear Adm. James Murdoch, the LCS program executive officer, reassigned Riedel “pending an investigation into allegations of inappropriate personal behavior,” Johnson said.

NAVSEA is conducting the investigation. Once complete, the findings will be reviewed by Vice Adm. Kevin McCoy, the chief of NAVSEA, and a final determination will be made as to Riedel’s status, Johnson said. There is no deadline for completing the probe, he said.

Riedel has been a program manager in the LCS Program Executive Office since August 2010, according to a profile on the professional networking website LinkedIn.

He has previously served as the program manager for amphibious warfare programs, and as a production and technical director for the San Antonio-class (LPD-17) transport dock ship, the LinkedIn profile said.

The sea frame for the LCS consists of two designs, the Freedom (LCS-1) variant by Lockheed Martin [LMT] and the one built by Austal USA for the Independence (LCS-2) version.

Edward Foster will act in Riedel’s place, Johnson said.
