In brief

About RFA Sir Lancelot

Full article ↗

RFA Sir Lancelot (L3029) was the lead ship and prototype of the Round Table class landing ship logistics, an amphibious warfare design operated by the British Armed Forces.
Sir Lancelot sailed with the British Task Force that took part in the Falklands War. Whilst in San Carlos Water, an Argentine plane dropped a bomb that penetrated her hull, but the bomb failed to explode.

How RFA Sir Lancelot 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 Kingdom is the country of registry for 2,394 vessels in this directory. The most common class under that flag is vessels this registry holds no type classification for (1,835 ships), and the median vessel measures 2,515 GT. Browse every ship flagged United Kingdom.

Narrowing to both dimensions at once, this registry holds 46 naval / patrols flying the United Kingdom flag.

RFA Sir Lancelot was built in 1964, making it 62 years old. It is one of 309 hulls in this registry delivered that year, a cohort whose median tonnage is 909 GT. 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 10 vessels to Fairfield Shipbuilding and Engineering Company, with a median tonnage of 26,313 GT, delivered between 1930 and 1964. See the rest of that yard’s output.

At 125.6 m overall, RFA Sir Lancelot is 39.1 m longer than the 86.5 m median for naval / patrols on record, with a beam of 60.0 m and a draft of 13.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5413642 this registry holds 6 other vessels, whose median build year is 1963 and which range from 1953 to 1987. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1964.

Its IMO number, 5413642, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 4×6 + 1×5 + 3×4 + 6×3 + 4×2 = 102 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
