How USS Kittaton compares

Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.

United States is the country of registry for 2,278 vessels in this directory. The most common class under that flag is vessels this registry holds no type classification for (977 ships), and the median vessel measures 1,706 GT. Browse every ship flagged United States.

Narrowing to both dimensions at once, this registry holds 239 tugs flying the United States flag.

USS Kittaton was built in 1945, making it 81 years old. It is one of 191 hulls in this registry delivered that year, a cohort whose median tonnage is 3,923 GT. Across the whole of the 1940s the registry holds 1,039 vessels, median 4,053 GT. The median build year across the entire registry is 1995.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8853568 this registry holds 14 other vessels, whose median build year is 1989 and which range from 1945 to 1991. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1945.

Its IMO number, 8853568, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 8×6 + 5×5 + 3×4 + 5×3 + 6×2 = 168 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
