The US Navy’s most technologically advanced warship broke down while transiting through the Panama Canal, the second setback for the $4 billion ship in the last two months.

The propulsion system of the USS Zumwalt (DDG-1000) had problems while passing through the canal and had to be towed in to the former naval station Rodman in Panama, according to Defense News. A spokesperson for the Navy wouldn’t say how long repairs would take, but one defense official told USNI they could take up to 10 days.

The official also said the Zumwalt made contact with the canal’s walls after the engineering problem, resulting in minor cosmetic damage.

The ship previously suffered an engineering malfunction in September that took around two weeks to fix. It also had “unspecified engineering trouble” right around the time it arrived at Naval Station Mayport, Florida, in late October, according to USNI.
