There's no word on a release date, although DICE says it's now targeting an early April release for both the Xbox One and PC versions of the DLC.
"We have decided to delay the Xbox One version of Naval Strike because we want to address issues in the animation system that hinder players from engaging targets in set circumstances using popular weapon configurations," said DICE.
"We know that many Battlefield 4 Premium owners wanted to play Naval Strike today. However, we didn’t want to release the new content until we believed it was quality content."
"We are trying to resolve these problems as quickly as possible and hope to release the update in early April for Xbox One and PC. We also want to remind Xbox One and PC owners of Battlefield 4 Premium that they will have two weeks early access for Naval Strike once it’s released. Thanks for your continued patience and passion for our games."
