No gross tonnage is recorded for this vessel, so it cannot be ranked by size. Rank is only shown where the underlying measurement exists.

Every value is as recorded in the source. Blanks are values the source does not hold — none is estimated from a sister ship or a class average.

In context
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 136 naval / patrols flying the United States flag.
The registry attributes 59 vessels to Avondale Shipyard, with a median tonnage of 25,742 GT, delivered between 1945 and 2006. See the rest of that yard’s output.
At 206.5 m overall, USNS Tippecanoe is 120.0 m longer than the 86.5 m median for naval / patrols on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8906602 this registry holds 69 other vessels, whose median build year is 1991 and which range from 1988 to 1996. That places this hull’s registration in the same part of the series; no build year is recorded for this vessel itself.
Its IMO number, 8906602, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 9×6 + 0×5 + 6×4 + 6×3 + 0×2 = 152 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
