In brief

About USNS Sirius

Full article ↗

USNS Sirius (T-AFS 8) was a Sirius-class combat stores ship of the United States Navy, named for Sirius (α Canis Majoris), the brightest star visible from Earth other than the Sun.
Sirius was built by Swan Hunter & Wigham Richardson for the Royal Navy. Laid down in 1965, she was launched in 1966 from Wallsend as RFA Lyness with the pennant A339 serving in the British Royal Fleet Auxiliary.
On 15 November 1980, the ship was acquired by charter by the United States Military Sealift Command. She was transferred to the U.S. Navy's Military Sealift Command in 1981.
Sirius was deactivated and struck from the Naval Vessel Register in 2005 and given to the U.S. Department of Transportation's Maritime Administration (MARAD), then assigned to Texas Maritime Academy under an agreement that it can be activated by MARAD at any time. During the fall of 2005, the Sirius served in New Orleans for Katrina relief, from 10 September until 29 November and at Lake Charles, LA for Rita relief until 2 March. Because of its extended relief effort the Sirius was unable to undergo a refit in 2006 to adapt its new role as a training vessel and comply with U.S. Coast Guard safety standards. Because the Sirius had not undergone a refit, it could not be formally commissioned as the USTS Texas Clipper III nor could it be used for summer training cruises.

How USNS Sirius 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.

At 14,113 gross tons, USNS Sirius is the 31,617th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 2.4 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 58,086 vessels this registry holds no type classification for held here, it ranks 17,750th by tonnage — larger than 64% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.

United States is the country of registry for 2,278 vessels in this directory, of which USNS Sirius is the 285th largest by tonnage. 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 977 vessels this registry holds no type classification for flying the United States flag, of which 110 are larger by tonnage.

USNS Sirius was built in 1967, making it 59 years old. It is one of 496 hulls in this registry delivered that year, a cohort whose median tonnage is 757 GT; within it this ship is the 14th largest. Across the whole of the 1960s the registry holds 4,074 vessels, median 844 GT. The median build year across the entire registry is 1995.

The registry attributes 124 vessels to Swan Hunter, with a median tonnage of 6,944 GT, delivered between 1903 and 2006. See the rest of that yard’s output.

At 159.5 m overall, USNS Sirius is 44.5 m longer than the 115.0 m median for vessels this registry holds no type classification for on record, with a beam of 72.0 m and a draft of 26.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 6706888 this registry holds 11 other vessels, whose median build year is 1967 and which range from 1965 to 1968. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1967.

Its IMO number, 6706888, carries its own check digit. The first six digits are weighted seven down to two and summed — 6×7 + 7×6 + 0×5 + 6×4 + 8×3 + 8×2 = 148 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
