Are you building a 1:350 scale modern USN warship model? More than likely you have noticed that the USN changed from white hull numbers shaded in black to a low visibility Lo-Viz pale gray, shaded in black. Your kit may come with the right decals but perhaps it doesn't. Perhaps it doesn't have the right numbers for the particular ship, which you are modeling. Hawk Graphics has the solution. They produce a decal sheet in 1:350 scale of Lo-Viz hull numbers of the USN. The sheet is Hawk D3507 and has hull numbers in three sizes, large, medium and small. Each size has rows of 1 through 0 with six rows in the large size, four in the medium and six in the small.
