 Other observers, such as Barnett, pointed to the difficulty the German Navy would have had in rearming the ship with German guns, given the fact that Germany possessed no designs for naval guns of that caliber or mountings suitable for use aboard "Salamis".He regarded the claim that she had been put into service "doubtful".Barnett's assessment was correct; a substantial rebuilding of the ship's barbette structures would have been required to accommodate German guns, and since guns available for naval use were not easily available owing to the needs of the German Army, work was directed toward German vessels under construction like the battlecruiser .
